We help our clients across London and the South East get their construction and engineering projects off to the best start. From measured building surveys to topographical surveys, we assist Architects & construction professionals looking for accurate drawings, value for money and great customer service.

Hi, I’m Tom, founder and co-director of THS Concepts. I started the business in February 2013. Before THS Concepts, I was a marine civil engineer working for a company called Red7Marine.

I started the business to provide local architects with quality survey information to base their proposed designs from. Obtaining accurate survey information for a building project from the start is important. I found that architects often lacked the time and the equipment to undertake this task correctly.

The business was started from my kitchen table, however, this quickly graduated to a small office nearby as the business grew.

7 years, three office upgrades and about 1,500 jobs later, THS Concepts is a team of seven people and one of the leading surveying businesses in South East England. We’re based in Leigh-on-Sea, recently voted the happiest place to live in the UK.
