We wanted to extend an existing shed to form a unique L shaped shed. The task involved dismantling half of the existing 12X6M shed, then building the new 6X12.6M section over the existing and new slabs. SGI were the only company remotely interested in the project. They have all the necessary engineering and design skills in house, and have created an extraordinary structure for us. Aside from building the new section, they also re-clad and re-roofed the remaining section of the existing shed, as well as inserting full wall and roof insulation. SGI was always prepared to go the extra mile, sorted out all the issues of the build quickly and with good humour, and the end product is something very special. Two of our neighbours were so impressed they engaged SGI for their own projects.
If the project is a little different, or a high standard of finish and attention to detail is required, my experience indicates that SGI will exceed expectations.
