Across different geographies and scales, this week's architecture news reflects a sustained focus on how cities and buildings are being recalibrated in response to evolving patterns of movement, work, and collective life. Across multiple contexts, public space and mobility remain central concerns, with streets, downtowns, and large-scale developments serving as testing grounds for new approaches to accessibility, resilience, and everyday use. Pedestrianisation initiatives and community-led visions point to evolving governance models and long-term urban strategies, while cultural and research-driven platforms continue to frame these changes within broader public discourse. In parallel, progress on major mixed-use and corporate projects underscores the growing integration of digitalinfrastructure, environmental performance, and flexible spatial frameworks within contemporary architecture.
Construction has officially broken ground on Tokyo's new global headquarters for NTT, a major Japanese technology company. The project is a key component of PLP Architecture's Tokyo Cross Park masterplan, a large-scale regeneration development in the Tokyo metropolitan area, first announced in 2022. On December 5, 2025, construction began on the first stage of the scheme, one of four towers planned within the masterplan. The NTT Hibiya Tower, designed by PLP Architecture and developed by NTT Urban Development in collaboration with Tokyo Electric Power Company, is a 230-metre-tall, 361,000-square-metre mixed-use building and forms the central element of the 1.1-million-square-metre Tokyo Cross Park Vision. PLP Architecture serves as Design Architect for the tower, as well as Masterplanner and Placemaking Strategist for the wider development.

As the landscape of architecture and urban development adapts to the modern climate, the traditional notion of construction has been significantly modified and adjusted. Specifically, principles of reuse, recycling, adaptive reuse, and the power of transforming existing structures into something more meaningful and sustainable have gained much traction. Looking at these curated collections of unbuilt projects, one can begin exploring a different way of looking at buildings and heritage, which is significantly more sensitive to the built environment.
From the austere office buildings of the United Kingdom to the proposal to re-activate a skyscraper in Ostrava, these diverse contexts tell stories of resilience, innovation, and a profound commitment to the existing built environment. Offering a new way of looking at things, the projects champion adaptive reuse and activation concepts.

The City of London has released new visualizations showing how its fast-changing skyline will look by 2026, as 13 schemes are currently under construction or due to begin construction in London’s Financial District.
Amongst the rapid materializing of telecoms, media and tech companies within the Blackfriar’s Southbank region, PLP Architecture has been chosen for the design of a new office building with the challenge of successfully integrating into the ever-changing local fabric.
“Our proposal speculates on the nature of the contemporary office tower,” explained the firm. “What is the architectural expression of today’s high-density workplace? How does the building acquire an identity specific to its media/tech occupiers and how is that identity conveyed to the city?”

The Ensemble Immobilier Tour Maine-Montparnasse (EITMM) has selected 7 notable firms to continue to the second round in a competition for the renovation of Tour Montparnasse in the Montparnasse district of Paris, France.
Often cited as one of the architecture world’s most hated buildings, Tour Montparnasse has been criticized for its discordance with the Parisian urban landscape – just two years after its completion, new buildings over seven stories high in the city centre were banned, leaving the tower as an alien presence on the skyline.
With the launching of the competition, the EITMM hopes to transform Tour Montparnasse into a beloved landmark with a complete renovation of the facade, the building entry and all interior spaces. The budget for the project is estimated to reach over 300 million Euro ($330 million USD), and will be funded in entirety by the building owners.
British firm PLP has unveiled their design for a large complex at the heart of the Pearl River Delta in China.

PLP Architecture has received planning approval for its 62-story tower at 22 Bishopsgate in the City of London. 22 Bishopsgate, which will take the place of the high-profile "Pinnacle" designed by KPF and abandoned as a result of the financial crisis, will be the City of London's tallest building at a height of 278 meters. As reported by The Architects' Journal, the design of the project has been led by PLP co-founder Karen Cook, who worked on the design of the Pinnacle before leaving KPF in 2009.
PLP Architecture has released their new design for a skyscraper at 22 Bishopsgate. Set to be 278m tall, it will be the tallest building in the City of London, second only to the Shard in the UK. The site was originally home to the Pinnacle, a slightly taller proposal that stopped work in 2012 due to economic restraints. Located in the midst of the city’s cluster of tall buildings, the new design will pick up where the Pinnacle left off, reusing the already built foundations and basements.
