British travel brand Antler will open the doors to its UK flagship store at 100 Regent Street, London, on 21 April 2026. Marking the brand’s first standalone UK store under its new ownership, the opening represents a significant milestone in Antler’s journey and global retail expansion strategy. Spanning two floors and over 2,400 sq ft, the Regent Street flagship opens as the home of Antler. The store affirms Antler’s brand positioning as The British Travel Lifestyle Brand through a considered physical environment with sensory details introduced through lighting, materials and Antler’s signature scent. 100 Regent Street is designed as a destination that reflects Antler’s ethos that more travelled people make for a better world, brought to life through Antler’s collections of modern, functional travel goods for those who travel often. Located within London’s prestigious shopping district, Antler will join other iconic British brands, including Burberry and Mulberry, in its premium retail positioning. Designed in collaboration with award-winning design agency Checkland Kindleysides, the flagship brings together product and travel expertise within a contemporary, design-led retail environment defined by natural materials and a seamless artisan micro-cement finish that flows from floor to ceiling. The ground floor forms the primary retail space, centred around a bespoke 6-metre layered table designed as a focal point of the floor. The table features a soft, tactile surface designed to encourage hands-on interaction, allowing customers to open cases and explore the form and function of Antler’s collections. The ground floor is also home to a floral art installation by renowned British floral artist Hamish Powell. Woven around the central table and, along the right-hand wall, the installation introduces texture and seasonality into the space, drawing on natural materials and inspired by great British landscapes. At the rear of the ground floor, the space opens into a quieter haven designed for pause and reflection. Immersive brand visuals introduce Antler’s lifestyle world, offering a moment of rest and refreshments within the pace of Regent Street. The lower ground floor opens into a second retail space alongside the more intimate retreat, designed for discovery. The atmosphere shifts into a lounge environment inspired by the warmth of British hospitality with refreshments served, inviting customers to relax and explore the collection. The space converts from retail floor to an adaptable showroom and events space designed to host talks and cultural moments, bringing together London’s travel community. Furniture throughout the flagship has been designed and made by Toogood, the London based studio led by British designer Faye Toogood, introducing a sculptural yet functional design language throughout the store. In keeping with Antler’s wider engagement with British creatives, staff uniforms have been curated in collaboration with London clothing brand Studio Wylder, each piece finished with a bespoke Antler patch featuring the new monogram. The opening also marks the introduction of the Antler Monogram, a new brand code developed from the interlocking geometry of Antler’s icon and brand mark. Launching in a palette of signature green, archival coral and warm white, the monogram is a symbol of Antler’s design heritage and will launch with a flagship exclusive cashmere scarf and throw, packing cubes and a candle in Antler’s signature store scent, ‘Shared Worlds’. Introduced to mark the milestone opening of the Regent Street flagship, the monogram is designed to remain a long-term brand code, reflecting Antler’s evolution from heritage luggage maker to modern British travel lifestyle brand. Kirsty Glenne, CEO at Antler, said: “The opening of our Regent Street flagship is a defining moment for Antler and a powerful statement of our ambition. This store brings our brand to life as a destination that expresses our values, our heritage and our confidence in the future of physical retail, while creating a new, meaningful way for customers to engage with Antler. Regent Street provides the perfect stage for the next chapter of Antler’s growth.” The Regent Street opening follows four consecutive years of double-digit profitable growth with global sales reaching £52M, +17% YoY. Strategic investment into new product categories including bags and accessories has broadened Antler’s reach beyond core luggage to grow its consumer base, placing the brand firmly on track to reach £100 Million in global sales by 2029. This sustained global growth has also enabled Antler to accelerate its strategic expansion into a House of Brands, through acquiring Paravel and undertaking the expansion of Nere’s international business. Laura Thursfield, Retail Leasing Director, at The Crown Estate, said: “We are delighted to welcome Antler, an iconic British brand, to Regent Street. The arrival reflects our strategy to curate a street of best-in-class brands, led by flagship stores that reinforce Regent Street’s global profile. Antler’s opening marks the start of a summer of new arrivals and supports our ambition to create a forward-thinking destination that continues to evolve in line with emerging consumer trends.” Building, Design & Construction Magazine | The Choice of Industry Professionals
Watkin Jones has reached a major milestone on its 484-bed purpose-built student accommodation (PBSA) scheme in Bristol, with the Malago Road development securing Gateway 2 approval and progressing into full delivery. The scheme, located within the city’s fast-evolving Temple Quarter, is being delivered through a joint venture with Maslow Capital. Gateway 2 approval confirms that all necessary planning, funding and contractual arrangements are in place, allowing the project to move confidently into the next phase of construction. Works commenced on site in early 2026, with the development remaining on programme for completion ahead of the 2028 academic year. Once delivered, the scheme will provide a mix of modern student accommodation, including studio units and 30 non-en suite rooms, arranged across three buildings. The project will regenerate a brownfield site in a well-connected urban location, positioned approximately 100 metres from Bedminster station and within an 11-minute walk of the University of Bristol’s new Temple Quarter campus. Part of the development will operate under a nomination agreement with the university, supporting demand from its expanding student population. The scheme forms part of a wider wave of PBSA development across key regional cities, where supply continues to lag behind growing student numbers. Its proximity to transport infrastructure and major academic institutions is expected to underpin strong long-term occupancy and investment performance. Gwyn Pritchard, managing director at Watkin Jones, said the milestone reflects the strength of collaboration across the project team, as well as the quality of the scheme’s design and delivery approach. He added that the development demonstrates the company’s ongoing commitment to delivering sustainable, future-ready student accommodation in prime urban locations. Sky Mapson, senior director of origination at Maslow Capital, described Gateway 2 approval as a significant step forward, highlighting Bristol’s continued appeal as a market with clear demand for well-located PBSA. He noted that the scheme is well positioned to meet the long-term needs of the city, particularly given its connectivity and alignment with the University of Bristol’s growth plans. The Malago Road project reinforces the continued momentum within the PBSA sector, with developers and investors targeting high-quality schemes in strong university cities where demand fundamentals remain robust.

Bellway has submitted detailed plans for a development of much-needed new homes in South Hertfordshire. The company secured outline planning permission for the project and completed the purchase of the 12-acre site in Colney Heath in November last year. Its proposals for the 155-home development, to be known as Roestock Meadows and accessed off Roestock Lane, include a mix of one and two-bedroom apartments and two, three, four and five-bedroom houses. Ali Maruf, Managing Director of Bellway North London, said: “Our plans for Roestock Meadows would deliver a highly sustainable development which would make a significant contribution towards meeting the need for high-quality homes in this popular part of South Hertfordshire. “There’s a real demand for new housing here given Colney Heath’s proximity to St Albans, the city’s excellent rail links to central London, and the wide choice of highly rated schools within the area. “We have taken great care to ensure that our development would be a positive and sensitive addition to the village, with homes designed to reflect the appearance of existing houses in the area through the use of features such as dark weatherboard, dormer windows and gable-end chimneys. “Landscaping has also been carefully considered, with the majority of trees and hedgerows on site to be retained and a comprehensive planting programme put forward to improve biodiversity. We also plan to provide a new children’s play area in a central area of open space featuring three large trees for the community to enjoy. “This is a sustainable location for people to live, within walking distance of the village primary school, pub, takeaway and Post Office – and the new residents which the development would attract would further support these important village amenities. “We have also committed to significant financial investment in local education, health services, bus routes and community facilities as part of the planning agreement for the outline permission already in place for the project.” Bellway North London is currently building homes across Hertfordshire – at King George’s Vale in Cuffley, Forster Park in Stevenage and St James’ Park and Goodsyard in Bishop’s Stortford.

Commercial property developer Wykeland Group has submitted revised plans for a stylish new hotel in Hull city centre, under the Marriott group’s chic Moxy brand. Subject to planning approval, a £25m investment would see the hotel built opposite the city’s Connexin Live arena. Wykeland already has planning permission for a hotel on the site. With Moxy now lined up, revised plans have been submitted to Hull City Council to meet the hotel brand’s specific requirements. The development is planned for next to the recently-restored Castle Buildings and former Earl de Grey pub, and delivery of the hotel would mark the completion of a transformative regeneration project across the wider site. Jonathan Stubbs, Development Director of Hull-based Wykeland, said: “We’re proud of our work to restore Castle Buildings and the Earl de Grey and the development of a Moxy hotel would complete this prominent development site, as well as being an impressive addition to the Hull skyline. “The hotel’s location, on the doorstep of the Connexin Live arena and close to Hull’s city centre, marina, Fruit Market and Old Town, make it the perfect location for both leisure and business visitors. “These revised plans ensure the building reflects the stylish Moxy brand. Approval of the planning application will pave the way for the development of a high-quality new hotel that the business community, the tourism and hospitality sectors, and visitors to Hull have been crying out for.” The revised plans are for a seven-storey hotel with 122 bedrooms. The ground floor would include a bar and food area, a gym and a relaxation space, and business section. The hotel would meet a pent-up demand for accommodation in the city centre. Independent market research commissioned by Wykeland found there are 100 nights every year when city centre hotel capacity is full, with potential visitors forced to stay outside of the city. It would be owned by Wykeland and operated by Legacy Hotel Management Services, which manages more than 25 hotels across the UK on behalf of developers, investors and property owners. Moxy is Marriott’s quirky, non-traditional brand, offering guests a buzzing, contemporary vibe. Guests are welcomed with a drink as they check in at the bar, with convenient food options available both in the bar and at a grab-and-go counter. Moxy hotels can be found in 130 locations in more than 25 countries, with each hotel designed with a unique theme reflecting the host city. In the UK, Moxy has hotels in major cities including London, Birmingham, Manchester, Edinburgh, Glasgow and Belfast. Internationally, Moxy can be found in the likes of Bangkok, Shanghai, Los Angeles, New York, Paris, Amsterdam, Barcelona and Lisbon. Molly Turpie, Senior Manager, International Hotel Development, for Marriott International Hotels, said: “We’re excited at the prospect of creating a hotel that reflects the spirit of the city while delivering the high standards and global reach of Marriott International. “At Moxy, we believe hotels should be more than just a place to sleep – they should be social hubs, full of energy, creativity and personality. From check-in at the bar to buzzing communal spaces, the brand is all about creating memorable experiences at an accessible price point. “Hull’s independent spirit and cultural vibrancy make it a natural fit for Moxy, and we’re excited at the prospect of bringing something fresh, playful and distinctive to the city’s hospitality scene.” Building, Design & Construction Magazine | The Choice of Industry Professionals
Elderly residents at a sheltered housing complex in Rustington are getting together more frequently after a modern community hall was completed by Pilbeam Construction. Littlehampton and Rustington Housing Society said since the hall was officially opened residents have been leading busier social lives, attending quizzes, film nights and some even had their own Christmas celebrations in the space. The original 1970s communal building had reached the end of its life and was replaced by the award-winning Booker Hall, which features sustainable design, vaulted ceilings, large skylights, a fully equipped kitchen and ample space for events. Sussex contractor Pilbeam delivered the scheme alongside architects Studio Scott Taylor for owner Littlehampton and Rustington Housing Society, which said the new facilities are also providing an events space for the local community groups. The scheme was highly commended in the Sussex Heritage Trust Awards 2025 in the public and community category. Alan Corbett, managing director of Pilbeam Construction, said: “We worked closely with Littlehampton and Rustington Housing Society to ensure a smooth process and a positive experience for everyone. “It’s great to hear how well used the hall has been since opening and that it’s helped to create a much stronger sense of community for residents who are enjoying socialising in a modern and brighter space.” The project included the demolition of an outdated communal hall, laundrette and office facilities and replacing them with a Cross-Laminated Timber (CLT) framed hall, a modern laundrette, offices and new flats, all with sustainable design at their core. The new structures are energy efficient and purpose built, providing a warm, welcoming and modern design which is tailored for residents, the wider community and employees. Next to the hall, the laundrette offers a practical yet inviting environment, complete with a courtyard that allows for natural drying in good weather and a social space for residents located at the heart of the site. The timber frame and glue-laminated beams lean into the sustainable feel of the whole complex. Locally sourced flint, an element of locally sourced bricks and a zinc roof with concealed gutters ensure the buildings are not only visually appealing, but also environmentally sound. Emily Scott, director of Studio Scott Taylor, the project’s architectural firm, said: “From the outset we worked closely with the client team to nurture a project that incorporates their specific needs & creates welcoming spaces for staff and residents. “This project seamlessly integrates modern and traditional construction methods, making use of locally sourced materials, resulting in a unique civic building that enriches the local community and enhances the lives of those it serves. “The project has a strong emphasis on sustainability incorporating prefabricated timber construction methods, biodiverse planting and renewable energy sources. This includes solar panels, air source heat pumps and a natural ventilation strategy. At its heart, the project is designed to foster connections and promote the wellbeing of both residents and staff, reflecting a people-centred approach to architecture.” The communal spaces are available for hire by the wider Rustington community, creating an additional revenue stream for the housing society and strengthening local ties. The new office buildings provide employees with a collaborative workspace with large windows providing generous daylight and views to the surrounding planting. Sally Shepherd CEO Littlehampton and Rustington Housing Society said: “Since the communal hall officially opened, our residents have been holding a number of events which is making them feel less isolated. “For those residents who do not have or do not see their friends and family very much they can become lonely – the new hall is helping them integrate with others on a much more regular basis.” Community groups and residents who want to hire the hall can find out more here: https://www.rustingtonhall.co.uk/ For further information visit: https://www.pilbeamconstruction.co.uk/ Building, Design & Construction Magazine | The Choice of Industry Professionals
Brymec, a leading manufacturer and supplier of future-proofed solutions to the M&E sector, recently provided end-to-end M&E infrastructure for Portal Way, North Acton, a large-scale, contemporary residential development in west London. An ambitious project from the outset, the specifications were extensive, with multiple mechanical systems running across the building, including drainage, water, waste and pressure-regulated pipework. It demanded a technical partner involved from the earliest stages. Brymec, which has decades of experience working within high-rise structures, was appointed at the design stage to provide mechanical systems support, joining the project team from the first design review and providing support from specification through to on-site delivery. Early involvement makes a difference Brymec’s involvement began long before any pipe was laid. The team worked through early design reviews, shaping the drainage specification and advising on cast iron drainage systems suited to the building’s requirements. Multiple technical take-offs followed, with Brymec checking drawings, identifying potential issues and recommending the right M&E pipework and fittings across water, waste and pressure-regulated systems. Brymec approached the project as a technical consultancy as much as a supplier. Working as a material-agnostic partner, the team assessed each system on its merits, advising on material compatibility across drainage, water and waste systems and matching products and specifications to the building’s specific requirements. Recommendations were driven by performance, giving the contractor confidence at every stage. Carter Cowley, Key Accounts Manager, Brymec, said: “We were involved in the project from the outset, supporting the initial design conversations through to take-offs, onsite reviews and ongoing technical decisions. That kind of early engagement means problems get solved before they become costly on site. It’s the way we work.” Supporting prefabricated bathroom pods Prefabrication is an increasingly common feature of large-scale residential construction, used to reduce on-site labour demands and improve programme certainty. Portal Way was no exception. One of the more complex elements of the project involved prefabricated pods, including bathroom, shower and utility modules, assembled off-site before delivery. Brymec managed the prefabrication supply chain directly, supplying mechanical components to the prefabrication partners and ensuring everything arrived correctly specified and ready to install. The team then carried out on-site installation reviews as the completed pods were fitted into the building. That level of end-to-end support, from early specification through to installation checks, helped reduce labour demands on-site and kept the build programme on track. Having a single technical team backing the project meant the contractor had one consistent point of contact, regardless of which system or component they needed guidance on. Controlled delivery, consistent quality Delivery was managed through the Brymec Breeze supply model, giving the contractor the certainty of on-time, in-full delivery aligned to the project programme. Products arrived when they were needed, correctly specified and ready to install. The consistency of product quality meant installation teams could work without disruption, with components that fitted first time and required no reworking on-site. That reliability reduced site storage pressures and kept the programme moving. Throughout the project, Brymec adapted as new drawings arrived and the scope evolved. The technical team stayed close, monitoring updates and advising on any implications for the systems already specified. Adam Habib, Project Manager, CJ O’Shea, adds: “Brymec were with us from the start. They understood the project and what we were trying to achieve. When issues came up, we knew exactly who to call and they always had a practical answer.” A trusted partner across the full project For M&E contractors working on complex residential schemes, Portal Way is a clear example of what integrated mechanical systems support looks like in practice: a single technical team, embedded from design stage, delivering certainty from the first drawing to the final installation.

The team building the Northolt Tunnel for HS2 have reached a new milestone, completing the construction of 34 cross passages. Cross passages connect the northbound and southbound tunnel and are a safety feature which allows passengers to cross to the adjacent tunnel in the event of an emergency. The Northolt Tunnel is 8.4 miles long, running underground between West Ruislip Victoria Road in Ealing, west London – just outside HS2’s Old Oak Common station. At its deepest point, the tunnel is 35 metres below ground. The tunnel was constructed using four tunnel boring machines (TBMs) and the excavation was finished in June 2025. Following completion of the cross-passages, engineers will turn to the installation of reinforced concrete secondary collars, which will form the permanent openings for cross passage doors and enable the installation of permanent fire-rated sliding doors. It is expected that all structural works on the tunnel – the second longest on the 140-mile route between London and the West Midlands – will be completed later this year. The tunnel will then be readied for installation of the rail systems such as tracks and overhead power in the coming years. Malcolm Codling, Project Client for HS2 Ltd, said: “The progress made to construct the Northolt Tunnel demonstrates the commitment of our teams to deliver this vital infrastructure efficiently and safely. “Completing the construction of the cross passages is an important step towards finishing the civil engineering on the tunnel which will allow us to ultimately begin rail systems work including laying track.” The connections have been made using a spray concrete lining (SCL) mining technique where the team methodically cuts through the ground between the two tunnel bores. The distance between the two tunnel bores ranges from 6metres to 20metres. The work is carried out using mini-excavators, and every metre of earth cut is supported with sprayed concrete lining while the cross-passage slowly takes shape. Once the team has completed the lined tunnel, a water-proof membrane is installed followed by a secondary concrete lining. 11 of the cross passages were constructed using a ground freezing technique. This method was adopted due the presence of water bearing soils with a high-water table present in the ground in the western section of the tunnel. The methodology required the team to insert freeze pipes through special tunnel segments to create a 2m thick freeze wall to stabilise the ground before excavation could take place. HS2’s London Tunnels Contractor is Skanska Costain STRABAG joint venture (SCS JV). They are responsible for the main works civils construction of HS2 between Hillingdon and Camden, bringing the HS2 line into Euston. Dave Hannon, Tunnels & Routeway Director from SCS JV said: “The completion of all 34 cross passages along the Northolt Tunnel marks another important step forward for the programme, demonstrating consistent progress across multiple work fronts and the coordinated effort of our teams working deep beneath London. “With this phase complete, we can progress on the next stage of works on the tunnel, with safety and productivity at the forefront.” Booth Industries in Bolton are manufacturing the doors for all the tunnels across the HS2 route. With high-speed trains passing within metres of the doors, they will be capable of withstanding constant 14Kpa pressure cycles, along with 2hr Integrity and 2hr Insulation against fire – a world first and setting a new benchmark within the industry. They are being manufactured using majority UK made steel. While the completion of the cross passages for the Northolt Tunnel demonstrates progress on the HS2 route, there is still a vast amount of work to do across the 140-mile route between London and Birmingham. Mark Wild, HS2 Ltd Chief Executive, is leading a comprehensive reset of the project to ensure the remainder of the route is delivered as efficiently as possible and for the lowest reasonable cost.
