Latest review:
Hi, Dan recently completed a loft conversion and ground floor extension for our house in Ealing. It is the second time I've used him for a loft conversion. We are delighted with the work, team, price and timing and I highly recommend him. Dan is entirely trustworthy, and the team are a mixture of his family, friends and choir group. Like all projects there were a few snags and without fail Dan was pragmatic, helpful and keen to make sure we were happy with the quality at the end. I've recommended him to neighbours on both sides who are both pleased and happy to recommend him.

We are extremely happy we chose to use Phil for our loft and extension design. Phil is professional, extremely accommodating and a pleasure to work with.

His design ideas were smart and he presented us with a number of workable options. We wouldn’t hesitate recommend Phil and would certainly use again for any architectural works.
