Hello everyone,

Attached are our current plans before submitting the building permit / planning permission application.
I would appreciate your feedback of any kind, including suggestions for cost savings or any potential mistakes by the architect / draftsman!

Project: Single-family house with basement, granny flat (mainly for rental, 40m² (430 sq ft) * €11 = cold rent) in the basement, double precast concrete garage + 2 terraces.
Construction type: Prefabricated wooden frame house + precast concrete basement + precast concrete garage.
Compared to our plans from a few months ago, we have:
- mainly reduced the living area by about 25%, thus also reducing the house length and width.
- changed the kitchen and garage to a simple standard form with standard dimensions for a precast concrete garage 6 x 6m (20 x 20 ft).
- changed the window design.
- added a photovoltaic system + battery storage for KfW 40+ standard.

Good luck
Luke

The project is a bit too large for you. Remove the granny flat and redesign it as a two-story building.
Alternative: Check the terms for additional financing beforehand.
Based on my own experience with building on a slope, I would suggest that you might need an extra 100,000 to complete it as shown in the plans.

Does the angled parking space work well for driving in and out? Is it intended for the secondary apartment? If I understand correctly, you would never be able to park in front of the garage because it would block the other parking space.

Are you all aware of the actual ceiling heights? On the ground floor, it will be about 2.4 – 2.45 meters (7 ft 10 in – 8 ft) high. In the basement, meeting the required 2.3 meters (7 ft 7 in) for rental units will be tight.

What the house completely lacks is storage space.

I have to agree with kaho674 and also say at the beginning: the ventilation system (EWL) would be a complete no-go for me.
Thanks @hanse987.
We need at least 2.36 meters (7 ft 9 in) in the granny flat. On the ground floor, 2.4 meters (7 ft 10 in) is sufficient for us.
We will discuss this with our architect.
Do you then "simply" build deeper if more ceiling height is needed?

Thanks for your info.
Including the granny flat makes it more expensive, but it’s also intended as an investment. A 40m² (430 sq ft) apartment to rent covers basement costs + granny flat costs 30,000 euros more? About 440€/month rent (minus reserves etc.). I myself lived as a student in a basement granny flat in a single-family home. Everything was great.
What do you think the basement with the granny flat will cost?

When children are playing, we stay on the terrace at the front of the house; otherwise (in the evenings, etc.), we use the terrace above the garage. Privacy screening is also planned.
There is very little traffic, it’s a shared street with a 30 km/h (18.6 mph) speed limit zone.

This is about the view from inside looking outside – I mentioned that before, or where is your dining table located? But do as you wish; if you prefer looking at the street or your neighbor’s garage wall instead of your own flowers, then your priorities are obviously different.

Thanks, Katja.
We have similar priorities to you; the planting is also planned as a privacy screen from the neighbors and the street along the edges of the terrace.
However, our architect did not include this on our plans at all. But he doesn’t need to.
