Sentinel Design & Build – Preserving the past, building the future

Who we are

Sentinel Design & Build was founded over 30 years ago by our MD Steve James Corbyn, and has grown to become one of the leading building firms in the Borough of Greenwich. Steve continues to drive the company forward, supported by a team of trusted trade professionals. From planning and project management through to the construction, electrics, plumbing and finish, over the years Sentinel has earned a reputation for high quality work backed up by friendly service.

What we do

At Sentinel Design & Build we have a wealth of experience restoring and refurbishing period properties to perfection. In addition, we appreciate good modern design and the benefits of new and innovative building materials. Our team includes an experienced architect, and we can help you plan layouts that give you more space, maximising the potential of your property.

Kitchens, bathrooms, loft conversions and extensions – whatever you need, we’ll help create your dream home. No job is too big or too small and our trustworthy team are always ready to help. Other services we offer include damp-proofing, chimneys, bi-fold doors, conservatories and more.

By popular demand we have launched two new divisions - Sentinel Roofing for all your roofing needs, and Sentinel Plumbing and Heating. Our Gas Safe team are ready to assist with any plumbing project including boilers and central heating.

Based in the heart of Greenwich, we carry out work across London and South East London, Blackheath, Charlton, Shooters Hill, Eltham, Plumstead, Lewisham, Brockley and surrounding areas.
