Collenmore is committed to bringing the highest standards of workmanship to

meet and exceed Client and Designer expectations.    

Collenmore is proud to hold an ongoing relationship with Strawberry Hill House, Sir Horace Walpole's 18th Century Gothic Castle just outside Twickenham

Our works at this beautiful Grade 1 Listed treasure have covered everything from the finest of joinery repairs to the replacement of the recently damaged front iron railings and stonework footings

" James and his team came highly recommended to me, and lived up to my expectations. The extension work carried on my home was of the highest standard. They are clearly dedicated professionals, were always friendly and reliable, and kept the project going without any stress to us. I wouldn't hesitate to call James for further projects and will be recommending him to my friends in the area, and quite willing to give him references for new clients".
