Lee replaced our old, rather tired looking uPVC porch with a fantastic new metal framed one. The quality of work is excellent. The finish is incredibly high standard, with careful attention to detail, including filling and shaping the ceiling around an odd toothed-edge lintel to retain the shape while still finishing the edges for painting. He and Lenny were great to have on the job; thoroughly decent blokes who took care to keep everything tidy and did a great job of cleaning up when it was all done. Price-wise, he was really competitive with other quotes. We wouldn't hesitate to recommend Design a View to anyone (we've already booked him to come back to fit new conservatory doors).

From start to finish, the team at Design a View were exceptional! They took the time to understand our vision and transformed it into reality, with incredible workmanship. The end result was outstanding and they went above and beyond to ensure we were happy with every detail. Communication was prompt and clear throughout the project, and the team was always professional and courteous. We would highly recommend them to anyone looking for someone that is reliable and skilled. We cannot thank you enough.
