Customer testimonials

They completed a 2nd storey, tandem garage conversion, rear extension, three new bathrooms and a new kitchen, and whole-of-house refurbishment. The workmanship was spot on and the fitters John, Jay and Shane each brought their individual strengths the project each with millimetre perfect work. The builder brought forward several suggestions that improved the original design, bringing the porch forward, as well has having a rear vaulted ceiling in the rear open plan area and moving the cloakroom to a better location. The contracted electrician, Craig showed great attention to detail and ensured the +50 downlighters installed on the ground floor were perfectly placed to give good illumination as well as symmetry. All the trades brought-in were top-notch. Covid 19 caused havoc with the schedule; the result was worth the wait. - Steve Mayne

With virtually no input from the Spa company as they have never installed one in ground or indoors, ours was always going to be a difficult build. However no one envisaged just how difficult it would prove, digging a pit for a Swimspa in the wettest February on record followed by a worldwide pandemic. They had to overcome major build issues, supply issues, a stressed client and a few heated debates along the way. What the core team managed to achieve really is quite exceptional. The quality of the build and finish, tidiness of Shane's team (considering this was maintained over a prolonged period of time is a testament to the tradesmen and their pride in their work). Their design and problem solving over key issues invaluable. Help and advice on mid build amendments and the addition of a bespoke glass cloakroom ensured the end result has proved to be a beautiful and life changing addition to our home. I would not hesitate to recommend Simon, Shane and the team. - Extension with in-ground Swimspa

We have now had our bathroom, kitchen and most recently our loft converted by Simon and the team. The first two projects were finished on time and with great results and we are very happy customers. The final project for the loft conversion has been challenging, we had 2 huge hurricanes and Covid 19 since February so extremely challenging times but I can say they adapted to each headache we all faced through no fault of their own and kept me updated on all the changes to the project and timelines due to Covid 19. Very happy with the final result and happy would recommend them without hesitation for anyone looking at forthcoming projects in their home. - J S
