Extension Builder

Home Extension ServicesPhoenix Extensions are extension specialists specialising in extension design, home extensions and new extensions. We are based in Swindon and carry out work all over Wiltshire, Marlborough, Swindon and further afield. We have over 20 years of experience in conversion design and pride ourselves on offering a quality, professional, reliable and friendly service to all our clients. We appreciate that having building work carried out on your home can be a stressful and worrying time. That is why it is fundamental to Phoenix Extensions that from planning to completion, all our customers have a 'stress free' service. We are proud that most of our work comes from recommendations from previous satisfied customers.

Complete Service

At Phoenix Extensions, we offer a complete extension builder service from design to completion and we can undertake projects large or small. We will always offer our complete dedication to you, our customer. We believe that the key to our success is that we recognise the importance of working within time constraints, exceeding our customers expectations and providing a speedy, high quality service.

Trust us to give you honest advice as to whether one of our bungalow extension, Garage Conversion, kitchen extension or bathroom extension solutions will best meet your home's individual needs and requirements whilst ensuring your new conversion or building extensions are in-keeping with your home's current design and style.

Quality Workmanship and Customer Satisfaction

Our continual commitment to quality workmanship and customer satisfaction is at the heart of our business. All of our team are professional, punctual and friendly and take steps to ensure that your home is treated with the respect it deserves. We all work closely together to ensure all of our customers are totally satisfied.


We would like to take this opportunity to once again tell you how pleased we are, not just with the new building itself, but also with the way in which the work was undertaken. We were very impressed by both the ability and competence of the builders, and we have been recommending Phoenix Extensions to friends. quoteright
