    My name is Paul and I've been in the building trade since leaving school 40 years ago. I started out as a steel fixer, then went to college to gain a City & Guilds Level 3 in carpentry & joinery. Over the last 40 years I have become proficient in all aspects of the building trade. I specialise in extensions, loft conversions and refurbishments. I have had refurbishments featured in Home & Gardens Magazine and The Daily Telegraph. I live in Sidcup, but am willing to travel. All my work has been on personal recommendation. I pride myself on providing a quality service at a fair price and support the client from the beginning to the end of the job.
