Lightweight hall for low-cost do-it-yourself house raising

The paper presents design of a single-nave hall with the span of 12 m and pole height from 3.0 to 4.5 m. The hall can be used for warehousing goods, garaging vehicles or shedding farm animals. Construction material is mostly round timber. The structure consists of a strut brace frame with reinforced saddle diaphragm beam in longitudinal module 3.6 m, timber binding rafter and transversal trusses. Material, construction type and solution of details meet requirements and possibilities of do-it-yourself manufacture and assembly. The construction system of the hall has options for the rigid damp-proof roof course or for the prestressed canvas made of technical textile with water-proof surface finish. Foundation of the building is on concrete abutments, or – in a less traditional way – on concrete-encased poles in the ground shaft. Optional technical solutions (textile roofing, pole foundations) can reduce the framework costs including roofing by about 9% and total house raising costs by about 45%.
