R&D Architects Ltd was established in 1991. It is an RIBA Chartered Practice based in the London Borough of Redbridge.

The principal of the practice, Stephen Radley, has been a Chartered, formerly Corporate, Member of the RIBA since 1979. He has a range of experience extending through all types of domestic projects, from modest extensions to complete new houses, and apartment buildings, and including works to veterinary surgeries, primary schools, and church halls.

Originally based in Loughton, Essex, the practice relocated to its present address at the end of 2005. The office is in Hainault, on the north east border of Greater London, with easy access to the M11 and M25 motorways, and the Central Line underground into London.

Since establishment, the practice has built up a considerable portfolio of work mainly for private clients, many of whom commission the practice more than once. The practice has developed a particular expertise in designing residential developments on awkward urban or ‘brownfield’ sites, which also meet the increasingly stringent requirements of the Building Regulations.

Since May 2013, the practice has been affiliated with Epping Forest District Council under the LABC Partner Authority Scheme.

The practice can also provide planning advice, including the preparation and submission of appeals against refusals of Planning permission, or co-ordinate with, if necessary, other consultants providing quantity surveying, structural, mechanical, and environmental engineering services, party wall surveying services, and CDM2015 Principal Designer services.
