My Warmalog Modetro had proved to be brilliant! It arrived as expected and 3 of us erected it on an adjustable framework base. All parts fitted together with no major setbacks. 4 months after delivery there have been no problems. I use it as a teaching room ( clarinet and saxophone) and office/rehearsal space. It warms up quickly and retains its heat in this cold weather. No complaints from the neighbours as it's pretty sound proof.
Went together very well apart from the doors. Made sure it was all square and level. I adjusted as per instructions but was still out by 5 mm which I fixed with some home made washers. Would happily buy again. Delivery guy was great. Although I helped he shifted about twice as much as me. If I was doing it again I'd just pay the extra for 2 to unload.
