Construction standards

B20 to B25 concrete, mesh reinforcement top and bottom, and Styrodur boards beneath the top layer of reinforcement as integrated thermal insulation. Once the concrete has cured, usually after 28 days, we apply a Rooftek Pro Alu Mineral radon barrier and Glastek 40 Mineral waterproofing. A geopathic zone survey and a radon survey are part of the work. The slab is priced separately.

Depending on the technique you choose: 200 mm two-sided logs, round logs, logs hewn flat on the inside, or glulam beams. For two-sided and round logs we pick logs 280 to 500 mm in diameter, usually larch and pine with as few knots as possible. Isolena sheep’s wool insulation goes between the logs.

We build the non-load-bearing partitions to your requirements, in timber as standard so they don’t spoil the feel of a log house interior. We fill them with Isolena sheep’s wool, which insulates against heat loss and noise, helps maintain a pleasant indoor climate and is hypoallergenic.

Bochemit boron salt, a base oil and a pigmented top-coat oil from Kreidezeit. Our standard shade is red pine, which suits pine best, but you can choose another from the range of glazes. Wooden floors get a hard floor oil, and interior walls an oil enriched with natural wax. The top coat is renewed after 7 years.

BETA concrete roof tiles with fittings for valleys, hips, ridge and ventilation, counter-battens, roof battens and a Jutafol breathable membrane. Gutters and downpipes are galvanised steel or copper; connecting them to the stormwater drain isn’t part of the supply.

Triple-glazed timber Euro windows in Nordic pine with clear glass and full-perimeter locking hardware, plus Velux GGL roof windows. External sills in galvanised steel, internal sills in wood or plastic. We make the windows and doors to measure only once the building has settled. Roller shutters and blinds aren’t included in the price.

On the ground floor, a 180 mm Rigidur dry floor build-up with 2 × 60 mm Styrodur insulation, electric or wet underfloor heating and a 10 mm floor finish. In the attic, 35 mm board decking, 200 mm insulation and 20 mm Rigidur gypsum fibreboard. Boarding the loft on the third storey isn’t included in the price.

Floor tiles in the entrance hall, bathrooms and WCs on both the ground floor and in the attic, and wall tiles in the bathrooms and WCs up to 2 metres high, laid straight. White ceramic sanitary ware, plastic water pipes and grey PVC drainage.

Copper wiring, a consumer unit specified for the type of house, double non-combustible back boxes, and white switches and sockets. We run the wiring through channels milled straight into the walls, so you can move lights and sockets right up to the last moment.

A Hotjet air-to-water heat pump with a Siemens control unit, combined with an electric boiler and underfloor heating. On request we can fit conventional radiators or switch the system to direct electric heaters, gas or solar collectors. Every house has a chimney, but a fireplace or fireplace insert isn’t included in the price.
