An alternative design for a cabin or a house which utilizes an arched shape to provide a significantly stronger overall structure. The design includes a first roofing structure, a second roofing structure, a planar base, and a ridge beam. The planar base makes up the flooring for the cabin. The ridge beam is positioned parallel to and offset to the planar base to join and support the first roofing structure and the second roofing structure. The first roofing structure and the second roofing structure are positioned opposite to each other across the bridge beam and each includes a plurality of arched beams and a plurality of roofing boards. The arched beams are distributed along the bridge beam and are connected in between the bridge beam and the planar base. The roofing boards are distributed across and mounted to the arched beams to make up the roof of the cabin.
