Aviva Investors, the global asset management business of Aviva plc, announces it has reached completion of construction works at its One Liverpool Street development scheme in the City of London. One Liverpool Street has been designed and developed to create best-in-class office headquarters fit for the future. Energy-efficiency is a prominent consideration in its design, which features triple glazing, high-efficiency chillers, energy-efficient lighting, all-electric energy solutions, green roof, and HEPA filters for clean air. It is targeting a BREEAM ‘Outstanding’ certification for sustainability performance and an EPC ‘A’ rating. Providing 176,000 sq ft of office and retail space across the ground and ten upper floors, the scheme is already 90 per cent pre-let. Knight Frank, the global real estate adviser, will make One Liverpool Street its London and global headquarters while Dentons, the world’s largest global law firm, will also be based in the building after leasing almost 68,000 sq ft of space. Both firms will occupy four floors each. Completion at One Liverpool Street also caps a substantial piece of engineering. Built directly above Liverpool Street station, the new structure straddles three live London Underground lines, while bridging across existing infrastructure and wrapping around a six-storey ventilation shaft from the Underground system. This has required the construction of a highly-complex structure, including nearly 200 piles that extend up to 43 metres deep, whilst sophisticated bearings have been installed under every column and truss to offset vibrations from the railway lines below. One Liverpool Street is one of several high-profile developments being delivered by Aviva Investors in the City of London. 101 Moorgate, the sister schemes to One Liverpool Street, sits at the western entrance to the Elizabeth Line at Liverpool Street station and provides over 70,000 sq ft of office and retail space over its ground and eight upper floors and roof terrace. In September last year, Aviva Investors received approval from the City of London Corporation’s Planning and Transportation Committee for its proposed redevelopment of 130 Fenchurch Street, which will see the creation of a showpiece 34-storey tower. In August, Aviva Investors purchased the remaining stake at New Broad Street House, with an initial assessment into the building’s development potential suggesting it could provide up to an additional 100,000 sq ft of additional prime office space, subject to planning permission. Ben Littman, Head of Development, Real Estate, at Aviva Investors, said: “One Liverpool Street is a transformational scheme and, given its location above the London Underground network, one of the most complex developments to be brought forward in the City of London. Its completion is a significant achievement, testament to our development capabilities and the expertise of our construction partners on the project over the last five years of construction. “Supporting the City of London’s strategic ‘City Plan 2040’ to deliver 1.2 million sq m of additional office floorspace, this is an example of a flagship scheme that combines best-in-class facilities with pioneering engineering and modern technology making it ready for the future. We believe it will contribute significantly to investment outcomes for our clients and investors.” Tom Sleigh, Chairman of the City of London Corporation Planning and Transportation Committee, said: “One Liverpool Street is a remarkable achievement. Built above live railway infrastructure and delivered to the highest sustainability standards, it showcases the ambition, ingenuity and confidence that continue to define the City of London. As businesses from around the world choose to invest here, developments like this are helping us create the modern, sustainable workspace needed to support economic growth, attract talent and keep the Square Mile at the forefront of global business.” Building, Design & Construction Magazine | The Choice of Industry Professionals

RED Group, the specialist main contractor, has announced the appointment of its South West division to deliver two office developments at more than £42m, showcasing RED’s significant commercial impact in the region. Appointed by BlackRock and development manager LS Estates, the first of these two premier Cat A office redevelopments is at Portwall Place, Bristol. Redefining the city’s workspace market, Portwall Place will span seven floors and 150,000 sq ft of office space, designed by architects Buckley Grey Yeoman (BGY). The building’s market-leading amenity provision will include a café, gym, and communal workspaces, featuring Bristol’s largest roof terrace with views over the City Centre, the Brunel Mile, St Mary Redcliffe, the Floating Harbour, and the Mendip Hills beyond.  The team will also carry out external repairs to the building façade and construct over 7,500 sq ft of terrace spaces with improved ecology through green roof areas. Targeting EPC A, BREEAM Excellent, and Nabers 4.5, Portwall Place has been designed as an all-electric building with a calculated saving for embodied carbon at 75%, and works will complete at the end of 2027. The second of the two new projects is Pinesgate West in Bath, an £8m office refurbishment located along the Avon River, which will be the new headquarters for engineering consultancy firm, Buro Happold. RED South West has been appointed by WPV Developments, and are working to AWW Architects’ design, targeting BREEAM Excellent and EPC A. Removing the façade and replacing it with a new envelope will improve the building’s aesthetic and form a prestigious gateway into Bath, but also drive lower energy consumption by minimising solar gain. That operational energy reduction is also supported through the introduction of PV panels, with EV charging, cycle storage, and an external terrace adding to the desirability of the scheme for its future occupiers. This project marks a continuation of the relationship between RED South West and AWW, the latter celebrating its 50th birthday in 2025. The two Bristol-based businesses also partnered on Hollis Wharf, the £13m 45,000 sq ft mixed-used development in Bath, and a £15m health hub in Weston-super-Mare. James Devey, Divisional Director at RED South West, commented: “These two premier office projects highlight RED’s dominance in the region, expertise in sustainable development, and sensitivity to local heritage. Set to be the largest commercial refurbishment in the South West, Portwall Place is a landmark scheme for Bristol and one that will be looked to as a benchmark for the office market here. Pinesgate takes the same inspiration, building on Bath’s industrial heritage whilst keeping sustainability a priority. These schemes will really stand out, in cities where there is huge demand for quality office space, and we have a big role to play in delivering them.” Jamie Furse, Director and Architect at AWW, said: “Pinesgate will be our third project with Red South West, following Hollis Wharf and Weston Health Hub, so our working relationship has already delivered some really positive outcomes for our region. As Pinesgate sets the pace for future developments in Bath, we were always keen to partner with a construction team that truly understood its complexities, with a thorough appreciation of what makes the city unique. As AWW celebrated its 50th year, it was incredibly rewarding to continue delivering projects that set benchmarks in design and helped shape the future direction of architecture across key South West locations.” These appointments follow the news that RED South West has celebrated project completions totalling more than £65m, most recently completing the £15m Millstream development, as the final piece of the Chocolate Quarter Retirement Village. Following the successful delivery of the Chocolate Quarter Retirement Village, St Monica Trust has now appointed the South West division as its construction partner on The Hub, a vibrant new social facility to be located at the heart of Cote Lane Retirement Village in Bristol.  Building, Design & Construction Magazine | The Choice of Industry Professionals

Mace has begun work on a landmark £150 million redevelopment of London’s former City Hall, returning to one of the capital’s most recognisable buildings more than two decades after originally constructing it. Appointed by St Martins Property Investments, the Kuwaiti-owned real estate investor, Mace will deliver the extensive transformation of the former Greater London Authority headquarters at More London into a modern, sustainable office and retail destination designed to meet the evolving demands of today’s commercial property market. The ambitious retrofit project will increase the building’s floorspace from 18,000 sq m to 22,000 sq m through carefully designed extensions around the existing 10-storey structure. Designed by Gensler, with Waterman providing structural, mechanical and electrical engineering services, the redevelopment will modernise the landmark while preserving its prominent position on the South Bank. One of the most significant aspects of the scheme will see the building’s distinctive leaning profile refined through the extension of its floorplates, creating larger and more flexible office accommodation for future occupiers. The existing glass façade will be removed and replaced with a high-performance cladding system, while landscaped terraces will be introduced to enhance both occupier wellbeing and environmental performance. The redevelopment also includes the infilling of the central atrium, installation of new mechanical, electrical and public health (MEP) systems, shell and core office fit-out, roof terraces and modern end-of-trip facilities, reflecting growing demand for premium workplace amenities within central London office developments. At ground level, new retail space will be incorporated alongside improvements to the surrounding public realm. Works will enhance The Scoop amphitheatre, Queen’s Walk and the wider landscape, creating a more attractive and accessible riverside environment for office users, visitors and the local community. Originally designed by Foster + Partners, the iconic building was officially opened by Queen Elizabeth II in 2002 and served as London’s City Hall until the Greater London Authority relocated to the Royal Docks in 2021. For the construction industry, the project highlights the continued importance of deep retrofit and adaptive reuse as developers seek to extend the lifespan of existing commercial buildings while significantly improving their sustainability credentials. Rather than demolishing and rebuilding, the scheme demonstrates how complex structural remodelling and modern engineering solutions can deliver future-ready workplaces with a substantially reduced environmental impact. Ged Simmonds, Managing Director for Private Sector at Mace Construct, said returning to More London presented a unique opportunity to build upon the legacy of a landmark development. He added that the focus would be on delivering a high-performing, sustainable workplace while enhancing the surrounding public realm and creating long-term value for occupiers and the wider community. With construction now underway, the redevelopment is set to breathe new life into one of London’s best-known commercial buildings, reinforcing the growing role of retrofit in shaping the future of the UK’s office property sector.

Vistry, the UK’s leading provider of mixed-tenure homes, has leased a 17,000 sq ft office at Skypark near Exeter.

Securing a leading house builder on a long-term lease is a powerful endorsement of Skypark’s quality and appeal.  Skypark is setting a new benchmark for sustainable, people focused business environments, not just in Exeter, but across the UK. It is a vibrant, beautifully designed employment site to support businesses to grow and thrive.” Councillor Paul Hayward, Portfolio Holder for Assets and Economy at East Devon District Council and representing Exeter and East Devon Enterprise Zone, said: “We are delighted to welcome Vistry to Skypark, one of the four key sites within the Exeter and East Devon Enterprise Zone. This is a strong vote of confidence in the quality of the business environment we are creating here and in Skypark’s continued appeal as a location for ambitious, growing businesses.

Construction is set to commence this October on one of the City of London’s most significant commercial developments, as Skanska prepares to begin work on the £282m redevelopment of 55 Old Broad Street. The scheme will deliver approximately 270,000 sq ft of premium office accommodation across 23 storeys, alongside new retail space and enhanced public realm, reinforcing the continued demand for high-quality, sustainable workplaces within London’s financial district. Originally promoted by Landsec, the development is now being taken forward by private equity real estate investor AshbyCapital, with Landsec continuing to play a key role as development manager. Completion is scheduled for 2029, with the project aiming to create a future-ready commercial destination just moments from Liverpool Street Station, one of the capital’s busiest transport hubs. Skanska’s appointment extends well beyond the core construction works. Alongside delivering the main building structure, the contractor will install the full mechanical, electrical and public health (MEP) systems, together with the Cat A office fit-out, providing occupiers with modern, flexible workspace designed to meet evolving business requirements. The project also includes the sensitive refurbishment of the Grade II-listed Bishopsgate Victorian Bath House, preserving an important piece of London’s architectural heritage, as well as the refurbishment of the neighbouring five-storey building at 65 Old Broad Street. Together, these elements demonstrate a balanced approach that combines contemporary commercial development with the restoration of historic assets. As occupier expectations continue to evolve, developers are placing greater emphasis on creating workplaces that deliver strong environmental performance, high-quality amenities and attractive public spaces. The redevelopment of 55 Old Broad Street reflects these changing priorities, with sustainability, connectivity and employee wellbeing all forming key components of the overall vision. Lee Marks, Executive Vice President at Skanska, described the project as an opportunity to create high-quality, future-ready workspace in one of London’s best-connected commercial locations. He added that the company was proud to bring its specialist expertise to a development of such scale and significance. Tom Smithers, Property Director at AshbyCapital, said securing Skanska represented an important milestone for the project. He noted that the shared ambition is to deliver a best-in-class workplace that combines outstanding design, strong environmental performance and enhanced public realm while meeting the changing needs of modern occupiers. With demand for sustainable, high-specification office space continuing to drive investment across the City, 55 Old Broad Street is set to become another flagship commercial development contributing to London’s evolving business landscape while supporting the ongoing regeneration of one of its most prominent financial districts.

Taking the highest office floor in the building at Level 47 on a 12-year lease, the new office space totals 8,479 sq ft, increasing King & Spalding’s total footprint to seven floors and almost 60,000 sq ft. King & Spalding signed on Levels 27-31 in 2023 and expanded into the 41st floor in 2025.  Spanning 550,000 sq ft the 47-office floor tower is now fully occupied. 8 Bishopsgate has proved to be a pioneering development that has attracted occupiers from a range of sectors from across the City and West End markets. The first development to truly deliver a range of occupier focused amenity, 10% of the building – representing 75,000 sq ft – is dedicated to amenity space. This includes the Think Tank, a dedicated 200-seat auditorium, with associated meeting rooms, alongside a range of food and beverage offerings on the ground, 1st and 26th floors.
