I instructed Sentinel to re-design my home to increase and make better use of the space with the build of a side return extension. They did a fantastic job of understanding my aims of marrying the historic building with new build unifying the property perfectly. I now have a stunning light filed kitchen/diner and a much larger bathroom. They also installed a new en-suite bathroom. Steve was a fantastic Project Manager, professional, helpful and very responsive with all our communication. I found all of the Sentinel tradesmen to be trustworthy, hardworking and a pleasure to have at my property. So much so, I have asked them to come back to re-design/configure my spare room/office. Highly recommended and have done so to friends looking to have building work done.
