Why homeowners call Garry
The space you need,
built properly the first time.
Outgrowing your home doesn't have to mean selling it. A well-built extension, loft or garage conversion gives you the extra bedroom, the bigger kitchen or the home office you've been missing, and adds value to your property at the same time.
The hard part is finding a builder you can trust to turn up, do the job right and see it through. With 45 years in the trade, Garry Travis has built his business on exactly that: straight talking, quality workmanship and taking responsibility from first visit to final sign-off.

What our customers say
"Can't thank you and those brilliant lads enough, we are so happy with how it looks, it's bloody amazing. Thank you all so much for all your hard work, it's going to be pretty quiet without you lot being around."
"From the first meeting with Gary he inspired confidence and we can honestly say that he hasn't let us down. He has totally delivered at every stage of the build, keeping us informed of the progress every step of the way. Gary estimated our build to take between 6-8 weeks and it was completed in 6 weeks. We would definitely recommend Gary to anyone contemplating any building work."
"Garry has completed three major projects for us. All the work has been carried out promptly and to a very high standard. Garry listens carefully to the ideas and wishes of the homeowner and contributes excellent (and creative) advice on possible solutions. We would not hesitate to recommend his firm for any building project."
