Vistry, the UK’s leading provider of mixed-tenure homes, has leased a 17,000 sq ft office at Skypark near Exeter. The business historically operated from two separate offices in Exeter, but they will now be located in a Grade A, 17,143 sq ft office at One Tiger Moth Road at Skypark. Leased from Devon County Council, the move will enable Vistry to unite its two regional teams under one roof, bringing 300 employees together to provide a best-in-class service for customers and partners. The EPC A-rated building offers exceptional, state-of-the-art office space situated over three floors and is located within Exeter and East Devon Enterprise Zone’s Skypark, providing easy access to nearby transport hubs. Vistry has long been the largest homebuilder across the South West, with its teams delivering hundreds of new affordable homes in partnership with leading housing providers, including Livewest. In 2026, the combined business expects to deliver 1,400 homes across the region. Peter Tannian, Managing Director of Vistry Devon & Cornwall Regions, said: “This move provides a fantastic opportunity for our South West businesses to become more aligned and ensure we provide the best and most efficient service for our customers and partners. Equally, the exceptional, Grade A office space at One Tiger Moth provides a great opportunity for our teams to collaborate and ensure best practice is being adopted across the business.” Councillor Simon Clist, Devon County Council Cabinet Member for Assets and Resources, and Chair of Skypark Development Partnership LLP, commented:“We are delighted to welcome Vistry Group to Exeter Skypark. 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. Vistry’s arrival brings hundreds of employees together in one place and further strengthens Skypark’s role as a major employment destination for the area.” Vistry was advised by JLL and Hector Pearce.

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.

Kevin Darvishi, Head of Leasing at Stanhope said: “Reaching full occupancy at 8 Bishopsgate is a landmark moment and clear endorsement of the long-term vision behind the building, from its sustainability credentials through to the breadth of amenity.

Plans have been unveiled for a landmark £1bn skyscraper that is set to become the tallest building in the City of London and one of the most significant commercial developments in Europe. Developed by Aroland Holdings, advised by Perennial Holdings, alongside Stanhope and Eric Parry Architects, the project known as One London will transform the City skyline with a striking new tower rising to 309.6 metres. Formerly known as 1 Undershaft, the development is expected to become London’s tallest skyscraper, the tallest office building in the UK and the joint-tallest building in Western Europe when completed in 2033. Located at the prominent junction of Leadenhall Street and St Mary Axe, the development will deliver approximately 1.2 million sq ft of office-led accommodation at the heart of the capital’s financial district. Designed to meet the evolving needs of modern businesses, the tower will provide high-quality workspace while reinforcing the City’s position as a global centre for finance, technology and innovation. The scheme received full planning approval from the City of London Corporation in December 2025, marking a major milestone for one of the capital’s most ambitious commercial projects. The development occupies a highly connected location, situated within a short walk of six London Underground lines and the Elizabeth line, offering exceptional accessibility for workers, visitors and businesses alike. In addition to its transport connections, the site benefits from proximity to around 1,000 hospitality venues and 27 acres of public open space, helping to create a vibrant environment that supports both professional and social activity within the Square Mile. Preparatory work is already progressing, with the deconstruction of the existing St Helen’s Tower now underway. The project team expects to appoint a main contractor later this year, with full construction anticipated to commence in 2028 following the completion of deconstruction and enabling works, as well as the finalisation of development financing arrangements. Once complete, One London is expected to become one of the defining buildings of the next decade, joining the ranks of the capital’s most recognisable landmarks. Beyond its impressive scale, the development reflects the continued confidence in London’s commercial property market and the growing demand for premium, sustainable and future-focused office space in prime locations. The project also highlights the ongoing evolution of the City of London, where new generations of workplace environments are being developed to accommodate changing occupier requirements, technological advancement and increasing expectations around sustainability, wellbeing and connectivity. As construction moves closer, One London is poised to play a major role in shaping the future skyline of the capital, creating a new focal point for business, investment and architectural ambition in one of the world’s leading financial centres.

A wave of high-spec office schemes across London and other parts of the UK is opening up substantial new work for contractors, as developers respond to demand for energy‑efficient, grade‑A space that helps employers attract and retain staff. April’s Glenigan Construction Review reports that office project starts totalled just over £4 billion in Q1 (January–March), a 75% rise on both the previous quarter and the same period last year. London dominated activity, supported by large City of London schemes and major data centre projects. Starts in the capital were worth almost £2.9 billion in January–March, more than double a year earlier. Other regions also posted strong gains, notably the South West (starts rose 15‑fold), Scotland (up 55%), Northern Ireland (more than 16‑fold) and the North East. Looking ahead, London offers the brightest prospects. Glenigan figures show the value of office planning approvals in the capital climbed by 90% in the first quarter compared with last year. The latest Deloitte office crane survey for London highlights developer confidence in resilient occupier demand for grade‑A offices. Anticipating a potential office supply gap later in the decade, the survey finds most developers expect their pipeline to either ‘increase’ (58%) or ‘remain stable’ (34%) over the next 12 months, while three‑quarters feel ‘more positive’ about leasing demand. Refurbishments remain a key driver: they made up around two‑thirds of all new office starts in the capital last year, covering some 3.1 million sq ft. Glenigan project data also flags major City of London schemes set to break ground in the coming months. The £330 million Alliance House at 60 Gracechurch Street—a 36‑storey tower with ground and basement levels—is due to start later this summer. Bovis is the main contractor on the 52,000+ sq m project (Project ID: 24112367). Construction on the £477 million, 53‑storey office at 99 Bishopsgate (pictured) is likewise expected to begin later this summer, following detailed consent, delivering over 144,000 sq m of new space. At 1 Undershaft – The Trellis, demolition is progressing and planning conditions are being resolved ahead of a planned start next spring. The 74‑storey, £510 million office tower by developer Stanhope will provide over 154,000 sq m, is at pre‑tender, and has a 60‑month build programme. Larger schemes are becoming more prominent in the pipeline. Although the total value of underlying office planning approvals fell year on year in Q1, approvals for major projects over £100 million rose by 2%. Beyond London, approvals strengthened in the South East (up 48%), surged in the North East (almost tenfold) and climbed in Wales (up 157%).

Contractor Legendre UK has secured the main construction role on the major redevelopment of 50 Stratton Street in the heart of Mayfair, London, on behalf of Berkeley Estate Asset Management. Designed by acclaimed architects Stiff + Trevillion, the 135,000 sq ft office development is set to deliver a premium commercial destination tailored to the evolving demands of the central London market. The scheme has been created with a strong emphasis on sustainability, modern workplace design and long-term building performance. Targeting both BREEAM Outstanding and LEED Gold certifications, the redevelopment will introduce a highly efficient all-electric building designed to align with the growing demand for low-carbon office environments across the capital. A key feature of the project is its focus on reducing embodied carbon through innovative construction methods and material selection. Lightweight steel will be used throughout the structure, alongside the addition of four new cross-laminated timber floors, helping to minimise environmental impact while supporting modern standards of sustainable development. The redevelopment will also significantly enhance the building’s external appearance and operational efficiency. New façades featuring high-quality stone cladding, aluminium-framed glazing and curtain walling systems will create a refined architectural identity suited to Mayfair’s prestigious commercial landscape. As demand continues to grow for sustainable Grade A office space in London’s prime business districts, the project reflects a wider industry shift towards environmentally responsible redevelopment and future-ready workplaces that prioritise energy performance, occupier wellbeing and design excellence.
