The office of Wiles and Maguire Ltd  is located in a bright and airy 1950’s school building close by the river in York. Founded in 2001 by Andrew Wiles and Martha Maguire the staff currently comprise of the director, Andrew Wiles, and a small team of assistants.



RIBA, MA (Sheff), Dip Arch, BAHons, AABC. Member of EASA, SPAB, Building Limes Forum and the C20 Society.

Andrew is a fully qualified architect and is on the Historic England approved register of ‘Architects Accredited in Building Conservation’ (AABC). The specialist research carried out for his MA was in the ‘timber construction of the early medieval period’ this remains a passion to this day. He sits as an architect member of the Sheffield Diocesan Advisory Committee and the Catholic Diocese of Hallam as their Historic England liaison. He is registered as a Church inspecting Architect (suitable for Grade 1 listed churches) with the Diocese of York, Sheffield, Ripon, Durham and Lincoln.

Andrew has worked exclusively with the repair and regeneration of historic buildings since 1988. His expertise and confidence in tackling any conservation challenge arises in part from these many years of experience actually seeing traditional skills being carried out by experts. For the first 10 years he worked with Martin Stancliffe who was at that time the Cathedral Architect for St Paul’s in London. A life encountering these special buildings is an invaluable resource but he also regularly attends, and contributes to, specialist courses and workshops to keep abreast of the ever evolving modern conservation technology and trends.
