My house is built by Tamarack. So far so good. Some of the stuff they provide as standard while other builders consider as upgrades. The quality is not bad, and their after service is good. For the 30 days inspection, all their trademen came at the same say to fix things, very efficient. I prefer Tamarack over Tartan. Most of tartan's homes use vinyl siding in the front, and the interior materials aren't as nice as Tamarack.
