    "John today finished our annexe built for my mother in our garden. I have only positive comments for the whole team - groundwork team, plasterers Alex and Ryan, Chippy Gareth, Electrician Andy and John himself who worked both as project manager and hands-on builder The whole build was well coordinated and beautifully finished. I was always involved in decision making and John went out of his way to make sure we were informed and happy. Can totally recommend Pinnacle to anyone who wants a professional builder, you won’t be disappointed."

    David - Image 1 "We engaged John and his company Pinnacle to build a two storey extension to our existing house in 2021. Large gable end style bedroom extension and further extended our kitchen entertaining area downstairs. Professional, caring, on budget. I would highly recommend them."
