Minerva House
The Minerva House redevelopment works will include the partial demolition of the existing building and extension comprising of additional upper floors and a new lower ground floor.

Stockley Park is an established business park near Heathrow, where The Bower at 4 Roundwood
Avenue has given the practice their first project with Exton Estates.
The existing building was ripe for refurbishment, and this became a complete transformation. Initially the thought was to retain as much structure as possible and change the whole layout to deliver a contemporary office environment; but to achieve this, the design evolved into extending the floor plates, relocating the
cores, creating a central atrium and replacing all the building services and the façade. This gives extensive flexibility, enabling anything from four separate tenancies per floor to a headquarters building for a single tenant.
Office space is created over three floors, served by four cores located around the light-filled atrium and reception space. The façade has been designed to balance daylight penetration and thermal efficiency and creates a striking visual appearance.
The MEP services solution uses all electric air source heat pumps as the base heating and cooling system with extensive energy efficiency and sustainable measures, delivering a BREEAM Excellent rating and A rated EPC. Features include 370m² of roof level PV panels, heat recovery, automatic lighting controls with daylight dimming plus energy management for tenant billing and demand control purposes.

The 47,900ft² area of The Smithson building in Farringdon was refurbished to high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering and energy consultancy to achieve an EPC B rating. The refurbished area is spread across basement and ground floor.

All MEP systems within One Hanover Street are being fully replaced, with new services distributed through the upgraded risers to each office floor. The refurbished building will benefit from high-efficiency heat-recovery systems, LED lighting throughout, intelligent lighting controls, a common network system and new fan-coil units among other modern building services upgrades.

The Kodak building in Holborn has been designed to achieve high sustainability benchmarks with WELL ‘Gold’ and BREEAM ‘Excellent’.

Watkins Payne carried out the Independent Design Review role for Block A at The Soapworks development.
