Surveying across London
Most of our work is in London. We have surveyed everything from one-bedroom flats and terraced gardens to Wembley Stadium, Whitehall and the Thames foreshore, for architects, engineers, contractors, developers and homeowners.
Our office is in Leigh-on-Sea, Essex. Central London is 45 minutes by train and the M25 is 25 minutes by road, so London sites are well within reach, and you deal directly with the surveyor who measured your site.
