Imperial Works is a heritage piano manufacturing workshop that had already been converted to office use when Coffey Architects got involved. Tired, outdated and with poor internal circulation, the building was not performing to its full potential.


The client asked us to increase the floor area, improve the worn-out building fabric, and improve horizontal and vertical access. Working around an in-situ tenant and to a limited budget, we delivered on time.


Whereas previous attempts had failed, our proposals for a discrete roof extension won planning permission, unlocking precious extra internal area to seal the project’s commercial viability.


A new occupier took a 15-year lease on the building during the design stage, establishing the building as their headquarters. The client sold the building before completion for a healthy profit.


The 1,950 m2 GIA project combines whole-life robustness in the choice of hard-wearing finishes and energy-efficient interventions for a delightful architectural end result. The building is now an up-to-date, comfortable office environment enjoying clever plays of daylight from new glazing that frame fantastic views of the London skyline.
