ᐅ Single-Family Home Optimization and Planning (180 sqm + Attic, No Basement)

Hello everyone,

I was directed to this interesting sub-forum through other threads, and of course, I would like to share our idea pool in the form of Draft 2.0.

First, a few facts about us:

Both 32 years old, no children, working full time. Two children are planned, but only after the house is built and before 40. So, relatively mid-term.

We plan to build in the front yard (650 m² (7,000 sq ft)) of the builder’s parents. The plot is signed, and the partnership agreement is in place. We envision a single-family house of about 180 m² (1,940 sq ft) with a double garage. We do not want a basement.
The house should preferably meet the KfW55 energy efficiency standard despite having a gas heating system. As a guy, I obviously find KNX great, but maybe Somfy Smart Home would also work. However, I would really regret it in the future if I squander that investment.

The cube shown in the drawing, originally made of exposed concrete, has now been clad with Trespa panels. The window shutters should be external Venetian blinds (Raffstores) in the basement and regular shutters on the upper floor. A large covered terrace (not visible here) is also very important to us since we really want to sit in the garden sheltered from the weather.

Additionally, we face the challenge that the driveway is from the southwest side, so we need to combine garden and driveway.

A wood-burning fireplace is very important to the builder. The airlock/transition zone between garage and house, connecting both, is also essential. We like the idea of a shared but “separate” bathroom; a bathtub is not necessary. An additional third, basic bathroom in the garage for garden parties is also planned (we live in a rural area of Lower Saxony, where corn and beer are enjoyed every other day…) but should be kept very simple.

I will actively participate in the thread and look forward to an engaging discussion.

Best regards,
