Sentinel have just completed my single storey extension and ground floor renovation and we are delighted with the results and overall very high quality of workmanship. All staff were punctual and extremely courteous, and they treated my house like it was my home and not a building site. Full and frequent contact was maintained throughout, which was really helpful as the job evolved and our original requirements changed. They made what would ordinarily have been an extremely stressful process a lot more manageable and I would not hesitate to recommend them. More...

Steve and the Sentinel team are amazing. We initially contracted them to complete a rear infill extension on our property but after seeing the quality of their workmanship, we contracted them to do a near total house refurbishment (all of which they achieved in an impressive 7 weeks). The whole team are a pleasure to work with. Would we use them again? Definitely. Would we recommend them . Absolutely. Thank you Sentinel! More...

I instructed Sentinel Design & Build in Sept '18 to renovate my historic cottage involving the demolition of existing bathroom extension and construction of a new kitchen/diner/art studio into the side return. Given the idiosyncrasies of the old building, which is in a conservation area, a lot of the work had to be sympathetically considered and the solutions considered and often bespoke.

Both the existing kitchen and bathroom were repositioned resulting in far larger spaces for both. The kitchen/diner/art studio has been positioned in the old bathroom and side return which provide multi-purpose space accessing the rear courtyard garden.

Steve and his team were absolute professionals in their professional and thoughtful approach. As I work from home, a lot of time was spent living in a building/construction site and I can honestly say the team were a pleasure to have around with their hard working, positive attitude to all tasks required.

Steve's architect was very professional to deal with, understood what I wanted to achieve from the design and talked me through every step from presentation of the design drawings to the planning application process.

Bespoke steel columns & beams were installed and exposed as I wanted to reveal the integral construction of the new build and for it to be obvious where the original cottage finished and the new build started. The new extension is flooded with natural daylight, enhanced with the installation of velux roof and sash windows.

Many reclaimed, salvaged & bespoke items were used in the build and Steve appreciated working with historic materials and considering how best they could be installed sympathetically into the work.

Mains drainage was replaced including the installation of an external manhole for the benefit of adjacent properties.

My daughter and I are thrilled with the outcome, we had an idea of what our cottage could be, but with Sentinel's help it has exceeded all our expectation. It's an absolute pleasure to live here.

Communication was straightforward, transparent and prompt.

The staff uniforms also gave the building site a smart look and all staff were courteous, hardworking and professional.

The bespoke front door was made to measure with the installation of an antique leaded coat of arms glass panel. Ironmongery also included a hand-made Arts & Crafts copper letterbox and matching vintage copper door knocker. This attention to detail has resulted in a wonderful blend of historic and contemporary styles, the ultimate urban cottage.

I recommend Sentinel Design and Build to anyone looking to have a renovation, extension or conversion done on their property who wants a competitive price and a fantastic hardworking & professional team.

The look on the clients face when the project becomes reality

A close family member used to be in the trade and offered me my first job. I then followed in his footsteps and set up my own business.
