About Us

Established in 1986, Thames & Newcastle (T&N) is a family-run, chartered building company with a reputation for excellence. For more than 35 years, we have been at the forefront of luxury residential construction, delivering projects of uncompromising quality across London and the South East.

Our clients trust us to deliver exceptional results with integrity and meticulous attention to detail. That’s why most of our work comes from repeat business and referrals.

Working directly with private clients, developers or architects, we offer both traditional and design-and-build contracts. Although our core focus is on the residential sector, our expertise extends to bespoke commercial projects. No matter the scale or scope, we bring the same high standards to every job.

What sets us apart is our highly skilled team, including in-house joinery, maintenance, and waterproofing specialists. As well as directly employing key tradespeople, we also collaborate with a trusted network of subcontractors, ensuring every project is delivered with precision, care and efficiency.

Reinforcing our commitment to professionalism and industry best practice, our directors are proud members of the Chartered Institute of Building (CIOB). As a chartered company, our business has been independently assessed to ensure we meet the highest professional, technical, and ethical standards. For our clients, this accreditation provides confidence that their project is in expert hands.
