"Dan and his team done a great job on our pole shed. It was and extension with concrete floors and enclosing the front with 2 roller doors and a PA door. The team are easy to deal with and do a good quality job. What was a standard open pole shed is now a tidy weathered in workshop. Wouldn't hesitate to use Southern Buildworks again'
