Hello everyone,
First, a brief introduction. I’m Andy, 35 years old, married, and embarking on building a house for the first time. I’m an employee, my wife is self-employed, and together with my parents-in-law, we plan to develop a large plot of land. The plot is already purchased and fully paid for with equity. For the construction of the houses, we have a budget of around €1.2 million, of which about €600k come from the sale of existing properties (my parents-in-law’s single-family house and our condominium) and a financing commitment for up to €600k.
We are currently in the planning phase for a multi-generation project, but my main focus is our house (“House 1”). The parents-in-law have already completed the plans for their bungalow (basically a modified ground-floor layout of their current house). The design is mine, adapted by the general contractor, and is currently with the architect for further revisions. I would really appreciate any tips, feedback, and ideas you might have.
I’ll follow the provided questionnaire:

Basement, storeys: No basement, 1 storey
Number of occupants, ages: 2, aged 35 and 31. Planning for 2 children
Office: Yes, space for two desks and some filing
Guest bedrooms per year: 10-15
Open or closed architecture: Open
Conservative or modern construction: Modern
Open kitchen, island: Both yes
Number of dining seats: 6-8
Fireplace: Nice to have but not essential
Music/sound wall: No
Balcony, roof terrace: No
Garage, carport: 2 garage spaces
Utility garden, greenhouse: Herb garden
Additional wishes: Dog shower
House design
Designed by: My design, implemented by the general contractor
What do you especially like? The atrium as a visual centerpiece and the related openness of the house
What do you dislike? Some wasted space, inconvenient furnishing of the walk-in closet due to 4 doors
Estimated cost according to architect/planner: €675k (approx. $720k) including paving, exposed concrete floor/wood flooring, painting, partial air conditioning, and additional upgrades. A horizontal roller shutter to close the entire atrium is also included (about €15k).
Personal price limit for the house including features: €750k (approx. $800k)
Preferred heating technology: Heat pump, photovoltaic system planned
If you had to give up something, on which details/extras
- could you compromise on: space in the parents’ area, 2 lift-and-slide doors in the atrium, lift-and-slide door in the living room
- could you not do without:
Why was the design made as it is?
After the attempt to build one large house including a granny flat on the front building plot was rejected, we are opting for two houses. To avoid further discussions about eaves height, we are building bungalows.
Contour lines:
Unfortunately, I cannot attach the PDF, but I hope the numbers are readable.

There are many points here that give me pause... The budget shouldn’t really be an issue. The total amount covers both houses, and my in-laws’ house is significantly smaller. We also have a good buffer just in case, which we’d prefer not to use since it yields much more than the loan interest costs us.
A partial basement was once considered but was later dropped for various reasons (including the groundwater level and the location at the foot of a slope. Right behind the house, we have two well shafts that aren’t very deep, and about 150m (500 feet) further east there is a stream).
We basically like the shape, but I’m increasingly realizing that it’s rather impractical...
I quickly sketched an alternative. The kitchen in the center, the living and dining rooms on either side. The children’s rooms and office can be swapped depending on the needs.

Hmm... then logically the dining area would also be in the center, meaning everything would be rotated around the original point. But then the pantry would be quite far away.
Actually, I quite like having the kitchen in the middle. It forms the center of the living area, and while cooking, you have a view into the atrium (whatever ends up being in there). A small dining space should definitely be included there as well.

Surface water runs down from three sides and collects at the lowest point, which is exactly at the corner of the house. Therefore, it only makes sense to have a basement on the lower side of the terrain. I would like to avoid creating an even lower point by adding a basement.
Unfortunately, a staggered floor level is not possible due to the height restriction, at least not without covering the single-story section with a shed roof. The bungalow originally came about more as a last resort, but I've actually come to find it appealing to have everything on one level.
We initially wanted to build a large house (shed roof / staggered floor), but the building authorities objected. According to them, the maximum height of 3.50 meters (11.5 feet) applies to the western (left) and southern (bottom) hillside sides, as well as the rear building plot to the west and north. Furthermore, for flat roofs, they use the top edge of the parapet as the reference height, even though the development plan clearly states "intersection with the roof covering." This caused a huge dispute, and before we even consider legal action (time, money, nerves), we decided to build in a way that leaves no room for discussion.
The first plan looked like this:
