We’ve had the SWRT Expendable House 40×20 FT for a little while now and so far we’re really happy with it. I’ll be honest, I wasn’t sure what to expect ordering a house like this, especially without seeing one in person. Once it arrived and was set up, though, it looked really good. There’s a lot more room inside than I expected and the windows make it feel bright during the day. We’re using it as an extra living space for now and it’s worked out really well

I spent quite a bit of time looking at different prefab houses before choosing the SWRT Expendable House 40×20 FT. My main concern was whether it would actually feel like a real home once it was set up. It does. We have plenty of space inside and it gets a lot of natural light. The outside also looks really nice once everything is finished around it. So far we’ve had a very good experience and I’m glad we went with this one.”

We needed another living space on our property and didn’t really want to deal with a long construction project. That’s what led us to the SWRT Expendable House 40×20 FT. When it first arrived, I was surprised by how compact it looked before being expanded. Once it was set up, though, there was a lot of space inside. We’ve been using it regularly and it’s been comfortable. Overall we’re very pleased with how it turned out.”

We wanted something smaller for our property, so the SWRT Expendable House 20×10 FT made more sense for us than one of the larger models. I was worried it might feel cramped, but once it was set up I was actually surprised by how comfortable it felt. We added a bed, some storage and a few other things and it works really well. It’s exactly the kind of extra space we were looking for.”

Our SWRT Expendable House 20×10 FT arrived a few weeks ago and we’ve been really happy with it. We mainly wanted an extra room for guests and occasional use. Once everything was set up and we put some furniture inside, it felt surprisingly homey. It’s not huge, obviously, but the space is used well. For what we needed, it has worked out very nicely.”

I was looking for something simple for our property and came across the SWRT Expendable House 20×10 FT. What I liked was that it didn’t take up a huge amount of space but still gave us a proper room inside. After delivery and setup, we added a sofa, small table and some storage and it turned into a really useful space. We’ve been happy with it so far.”
