I started working in the building industry after studying brickwork at Norwich City College. I worked with my father doing hard landscaping and building. I then left to work with a building company that focused on heritage buildings.

In 2014 I trained as a floor fitter learning different aspects of flooring and then in 2020, I joined my brother James at J Thornton Paving and Landscaping. We have always worked well together and it was great to get back to landscaping again.

After leaving school I was fortunate enough to get an apprenticeship with a very reputable company in Norwich learning carpentry. After 5 years I achieved my NVQ level 1, 2 & 3 in carpentry. I have always taken great pride in my work and really enjoy what I do.

In 2014 my brother Grant and I started G & J building we completed jobs from as little as hanging one door right through to a complete new-build house. Throughout my career so far I have become an all-round builder who specialises in carpentry and kitchen fitting.

When I left school I went to college learning bricklaying while working for a small Norwich-based building company. I was lucky enough to work for a company that allowed me the time to perfect my trade and learn all avenues of building work. Throughout my time with them, I completed my qualifications in bricklaying, I also learned roofing to a high standard.

In 2014 I started G & J Building with my brother Jack, specialising in extensions and renovations. We wanted to expand and grow our business so in 2023 we merged with J Thornton Paving and Landscaping and now we have a complete team that offers a complete service.

James Thornton

After leaving school I started working for my dad doing building and landscaping whilst attending Norwich City College to get my bricklaying qualifications. I have spent my whole working career in the building industry and from a young age I've always had a passion for hard landscaping. There is a massive amount of job satisfaction in what we do and I still enjoy every job.

In 2018, I set up J Thornton Paving & Landscaping and in 2020 my brother Stephen joined me. We have always worked closely with Grant and Jack as we are all good friends and work really well together so in 2023 we merged two companies to become East County Developments.

Let's work together.
