I instructed the services of Sentinel 2018. I have an old characterful cottage but the space was not working on the ground floor so they were enlisted to build a sign return extension to create a large kitchen/diner, new bathroom & additionally a new ensuite bathroom in the master bedroom in existing loft conversion. I found all communication, site visits and meetings to be very efficient and professional. Unfortunately some serious structural issues were discovered in the property which meant complete demolition of the old bathroom extension had to take place and the new build area required specialist foundations. Also it was found that the mains drainage had collapsed and required replacement. Steve Corbyn and his excellent architect talked me through every aspect of this unique build and I felt clear at all stages & well supported through what, at times, was quite a stressful process (especially as my daughter & I were living on site). The build is now complete and I am absolutely thrilled with the end result. The design has taken the heritage of the old historic property into consideration and the extension is a stunning modern addition to be proud of.
