Report
UPDATE: William Green has admitted making mistakes on my project. Both in technical measurements and not following my brief. Unfortunately he has not offered a satisfactory resolution so we are complaining to the Architect's Registration Board. To anyone already working with William Green, please ask a professional to double check all measurements and calculations before planning or building regulation submission to make sure that the work is correct. The errors are very costly. I would also suggest being very wary of 3 potential fake reviews that have been posted one week after mine. William

I have worked with the William Green team on a large renovation and extension project on a period property in a conservation area in the centre of Bloxham. They understood our brief immediately and translated it into a workable, creative and clever design which brought the property into the 21st century whilst highlighting its period features. They managed to get all planning permission approved on the first attempt; quite an achievement with such a large project in the centre of a conservation area. They managed the whole project very professionally and were invaluable in solving various builder
