What Our Clients Say
"Had WestMod install a granny flat in the backyard for my mum. The whole thing was done in a few weeks — way faster than I expected. Communication was great throughout."
"They handled everything including council approval which I was dreading. Saved me so much time and stress. The home looks fantastic and is already rented out."
"Really straightforward process. They explained everything clearly, gave us a couple of layout options, and delivered exactly what we asked for. No surprises."
