More about usProject Testimonials
We are absolutely thrilled with the large rear kitchen and day room extension John and the team completed on our house in Guildford. They really understood what we wanted and went above and beyond to ensure that all the work was completed on time and to an extremely high standard. On a personal note, we genuinely enjoyed having Onslow Construction working in our home. We cannot recommend them highly enough and without any reservations.
The guys at Onslow Construction completed our 2 storey extension which gave us an amazing kitchen diner, utility, extra bedroom and bathroom. It has completely transformed our house. They were an absolute pleasure to work with, keeping to the time schedule and budget set at the start and the communication was great throughout. Even at the end when there were a few snagging points, they were brilliant at ensuring everything was completed. We would totally recommend them and would definitely use them again if we wanted any further work doing!
