Hello to all construction experts, thanks in advance for the support. I hope I am in the right subforum with my questions.
We are currently planning our single-family house and need some assistance. A plot of land is already available, and I have a few questions about it.
I have attached pictures of the plot and our planning. The marked stream runs underground in a pipe at a depth of 25-30 cm. However, the plot slopes down from the street about 90 cm towards the middle and is filled level with the street.
We intend to build a single-family house with two floors without a basement, 1.60 m knee wall, and 38° roof pitch. The residential area is very quiet and not located on a main road. The elevation of the site is 540 m.
KFW funding is not planned, but we want to achieve at least the KFW 55 standard regarding energy costs.
We are only having the shell construction done, including the foundation slab and roof.
We will do the rest ourselves, as my father owns a carpentry/joinery business specializing in windows, and we also have a plastering company in the family. Therefore, we will do floors, windows, doors, stairs, installation level, roof insulation, interior walls (non-load bearing), interior plaster, and possibly exterior plaster ourselves.
The electrical work will be carried out by me (master electrician), and I am active in this field.
We are currently undecided between timber frame construction and solid masonry.
Regarding timber frame construction, I have concerns about sound insulation within the house (children’s room above the living room with home cinema). Is good soundproofing of the intermediate ceiling possible here?
With timber frame construction, we can do much of the work ourselves, as we would only have the timber frame with plaster carrier board (or DWD board with air layer and wooden facade) constructed. Wall insulation and cladding would be done by us. We already built my uncle’s house ourselves this way (10 years ago). What bothers me about that house is that when the children play upstairs, you hear this very clearly in the living room below. However, it has an open beam ceiling with ventilation ducts running over the visible boards.
1. Are there any forum members with experience regarding other ceiling constructions? We do not need an open beam ceiling or have also considered a cross-laminated timber ceiling.
2. As an alternative, solid construction would also be an option—here only the outer walls and load-bearing walls—but I would prefer to avoid ETICS (external thermal insulation composite system) in this case and build monolithically if possible. Or do you think there are currently better alternatives?
3. We are planning with a heat pump and geothermal energy. Due to the plot size, I considered trench collectors, but my question is whether they have to be directly next to the house or if they can also be located a bit away from the house as shown in the drawing? The lines would then arrive at the garage approximately.
4. The heat should be distributed via underfloor heating in the rooms, and additionally, a stove with a water jacket is planned in the living room to support the heating. I was thinking that the heat from the stove would be fed into the underfloor heating circuit and the hot water circuit via a mixing valve.
5. A central ventilation system is not planned; instead, decentralized ventilation in the living area, kitchen, bathroom, and possibly bedrooms.
Maybe you have some ideas
