House Design
Planner:
- Do-it-yourself; adapted by planner to the site
What do you particularly like? Basically everything needed is included; the sloping site makes it a bit more complex; driveway to garage is almost level as is the terrace; the view facing south is nice
What do you not like? Why? Upstairs bathroom is too small; would like walk-in shower and bathtub; widen the building by one meter (3 ft)?
Personal budget for the house, including fittings: 550,000
Preferred heating system: underfloor heating

Hello everyone,
We have a nice plot with a slight slope and want to build a new home. All rooms are basically included in the design, but we would appreciate other perspectives. The upstairs bathroom seems too small at the moment, and the layout feels unbalanced.

So am I correct in assuming that this is your entire plot of land and not just half of it?

Man, having to extract every bit of information from you like this is really getting frustrating for me.

Correct. Sorry, I thought that was clear from the plan. I have no idea what the black line represents; it is not a boundary.

The top of the plan is north; the slope rises toward the southeast.

In principle, I find partially or fully integrated garages to be much more visually harmonious. However, as already mentioned, you also bring a dirty area into the house.

Regarding this particular plot, I think the southwest corner of the house is far too valuable for a garage. In summer, you have the evening sun there, while the terrace is already shaded.

kaho’s idea of using the basement for living spaces and possibly creating a connection (stairs in the garden) between the two terraces has charm.

If the driveway absolutely has to be accessed from the west, you could also consider a detached garage with a roof terrace, accessible from the ground floor. Both concepts would allow the stairs to be positioned one above the other at a practical location in the house.

How about placing your house on your plot first? That would have avoided a lot of confusion.

I would still recommend planning parking spaces only on the north side. Needing to park with a slight turn around the corner seems less problematic to me than the hundreds of thousands you’d have to spend on an unwanted basement with a garage under the house.

I would rather invest that money in an elegant multi-level terrace that connects the ground floor and basement with stairs.

The idea of having a garage in the basement was suggested because it supposedly doesn’t cost significantly more than leaving out the basement, building an additional garage, and having to level the terrain. However, I have no idea if this is really true.

I find the idea of a roof terrace on the garage interesting. Is something like this easy to implement, or does it cost significantly more than if it were fully integrated into the building?

It will be significantly cheaper if you build only a basement level and a ground floor. A basement level is not a cellar. It is a full floor with living spaces on the side with windows and utility rooms on the earth-retaining wall side.
