Duval House, Harmondsworth



Duval House is located 19 miles west of Central London and strategically situated between the M4 motorway and Heathrow Airport only 1.5 miles from M4 junction 4 and 1.5 miles from Terminals 1, 2 & 3. The project comprised the redevelopment of a 0.5 acre brownfield site, formally used as a petrol filling station and vehicle servicing/repair garage, to provide a self-contained air-conditioned HQ office building of 12,263ft² (1,140m²) of high quality offices on ground, first and part second floors, together with 36 car parking spaces.

The scheme was developed by Ravenbourne in conjunction with Quintain Estates & Development PLC, with finance from Bank of Wales PLC. It was let at £28.54/ft² to Harvard Public Relations Limited guaranteed by its then parent company Chime Communications PLC. The created investment was sold for £4.415 million reflecting 7.49% Net Initial Yield to The Nuclear Generation Decommissioning Fund Ltd realising a development profit of almost 40% on cost.
