We are planning to build a 190 sqm single-family house according to Kfw55 standard in northern Lower Saxony. The shape of the house is relatively simple: gable roof with a protruding living room and a roof over the recessed area. One-story construction, 131 m² base slab, 1.6 m knee wall. Engobed clay bricks will be used, 24 cm mineral wool insulation for the roof and top intermediate ceiling, knee wall for inside walls top and bottom, knee wall for exterior walls, 16 cm mineral wool insulation, fully brick-faced (65 cents / brick). Tiles will be laid throughout the house (tile price €25 / sqm), roller shutters with belt drive everywhere, painting work up to €6K, decentralized controlled residential ventilation with heat recovery. Interior doors are budgeted at €240 including fittings. 43 m² window area. Gypsum plaster (but we probably want to change that). Adequate electrical installation. Basically, we just hope it will be robust. The offer does not include sand slab, water supply or drainage lines, earthworks, heating or sanitary fixtures. The offer is €233K. Another offer is now available for sanitary and heating. This includes: sanitary for one WC, one shower bathroom and one bathtub and shower bathroom (8 m²), underfloor heating with 15 cm laying distance (we had read that 10 cm would be better or even better to consider the whole thing more differentiated), heat probe drilling, 2 water connections for the garden (we had not requested this, but why not), 300 L tank (I still have to check if that makes sense, since the device actually already has a tank inside), supply and drainage lines in the house. The sanitary fixtures are also rather "robust" - the most expensive will probably be the bathtub (Kaldewei Mega Duo 180 x 90). The whole thing is supposed to cost €48K. We would like to build with the general contractor since he is local and has been recommended to us twice already - but we would still like to estimate whether the offer is okay, we are a bit unsure about the heating company.
