We’ve been appointed to deliver the UfAC system for the major refurbishment of 1-5 London Wall Buildings (25 Finsbury Circus), a Grade II-listed Edwardian office building overlooking Finsbury Circus Gardens in the heart of the City of London.

The sustainability-led redevelopment includes the restoration of the building’s historic façade, a two-storey extension and new rooftop terraces, targeting BREEAM Outstanding, WELL Platinum, NABERS 4 Stars, EPC A and WiredScore Platinum.

Working alongside IJM, Oxygen Asset Management, Carmody Groarke, Watermans, Quinn Ross, Quantem, and Ark M&E, AET will deliver the UfAC system across eight floors, serving 18,700m² of office space. The installation comprises 86 CAM—V DX units, 811 TU4 Fantiles™ and 195 FA7 Supply Air Booster Modules and will be one of AET’s first major projects to utilise lower GWP R32 refrigerant.

We’re pleased to be joining the team delivering the transformation of 95 New Cavendish Street, a prominent island site in the heart of Fitzrovia.

The comprehensive refurbishment will create over 2,000m² of Grade A workspace, bringing new life to the existing building through a new façade, additional floors, a Clubroom and communal roof terrace.

AET will deliver underfloor air conditioning across five floors, comprising 10 CAM—C units and 62 TU4 Fantiles™ — freeing the ceiling from conventional HVAC distribution and allowing natural light to travel further across the floorplate, while supporting a flexible, clean interior environment.

Targeting market-leading ESG credentials including BREEAM Excellent and EPC A, the scheme is another great example of how existing commercial buildings can be repositioned to deliver high-quality, lower-impact workplaces without having to start again.

Great to be working for our client, LBS Properties, alongside Ambit, Stiff + Trevillion Architects, Heyne Tillett Steel, Hoare Lea, and Bryair as the project takes shape.

Watch this space as the project progresses; completion is set for 2027.

We’re pleased to be delivering our underfloor air conditioning system as part of the deep retrofit of 25 St George Street, creating around 5,500m² of premium Grade A workspace in the heart of Mayfair.
The redevelopment will transform the existing building across eight floors, introducing new landscaped terraces and reconstructing the upper two floors in mass timber — reducing embodied carbon while creating a modern, high-performing workplace.

Targeting BREEAM Outstanding, WELL Platinum and NABERS 5 Stars, the scheme reflects the growing demand for retrofit projects that combine sustainability, occupant wellbeing and long-term performance.

AET will deliver our CAM—V UfAC system with 48 TU3 Fantiles™, providing a flexible HVAC solution that supports the project’s ambitious sustainability goals.

We look forward to working alongside our clients Old Park Lane Management, CO-⁠RE London, John Robertson Architects, Hilson Moran and Redworx MEP as the project progresses towards completion in 2027.
