Not flat-packed, not a kit, not a weekend with two people and an instruction booklet — the Tartu is \u003cstrong\u003edelivered as one assembled building\u003c\/strong\u003e, craned or rolled into position, and connected. That is the whole proposition, and it is why it costs what it does.\u003c\/p\u003e\n\n\u003cp\u003eWhat turns up is a blackened-timber cabin with a pitched roof, a \u003cstrong\u003efull glass gable end\u003c\/strong\u003e, aspen-lined walls, two-level benches with a backrest, and \u003cstrong\u003eLED lighting already installed\u003c\/strong\u003e behind the backrest and in the ceiling.

A 14 m³ room is a lot of air to warm, but with this much insulation it comes up quickly and holds temperature long after the heater cycles off — and it costs less to run than the volume would suggest. It also means the cabin is comfortable to sit in as a garden room when the heater is off, which is not true of a thin-panel sauna.\u003c\/p\u003e\n\u003cp\u003eOutside: 19 mm spruce, \u003cstrong\u003epre-painted black\u003c\/strong\u003e at the factory.
