Cundall started working with Derwent London on the Brunel Building from as long ago as 2004, in its earliest guise, and obtained planning in 2009. In early 2013, Derwent London entered into an option agreement with the freeholder and head leaseholder of the site, unlocking the development of an office development of approx. 24,000m² NLA of 15-storeys in height, alongside approx 100 apartments, with 15% affordable, contained within a 12-storey new build development.

The development is being constructed with a large combined basement, directly adjacent to the canal in Paddington, and directly opposite Paddington and the Crossrail interchange. The completion of the scheme should be shortly after the opening of the Crossrail Interchange in 2018.

Architecturally, the building is constructed with a complex exoskeleton, which will challenge the local existing building stock in the area in design terms, and will form a new landmark for Paddington.

In terms of sustainability, the building is designed to comply with the current BREEAM 'Excellent' rating, and contains Ground Source Heat Pump technology with Aquifer Thermal Energy Storage to comply with Westminster and GLA renewable and sustainability strategies.  

The on-floor services are designed with modern energy efficient ECDC four pipe fan coil units to minimise energy use. A significant area of the roof-scape is designed as terraces to be used as an amenity for the tenants, and affords fantastic views of London in all directions.  The building complies with the current Westminster and GLA renewables and sustainability requirements, and the design features CHP and ground water heat pumps connected to an Aquifer Thermal Energy Store (ATES).

Work on drilling the test boreholes for the ATES system was completed in 2010/2011.  The Contractor - Laing O’Rourke, was appointed in early 2016 and the main site works commenced early in 2016.
