Hello everyone,
we are currently planning to build a single-family house with a basement on a sloped site and would appreciate your feedback.
Development plan / restrictions
Plot size: 517 sqm (approximately 5,567 sq ft)
Slope: yes
Site occupancy index: 0.3
Floor area ratio: 0.3
Number of parking spaces: 0/1
Number of floors: 1.5
Roof type: gable roof
Maximum heights / limits
Other requirements: roof pitch 28-45°. Knee wall height 75 cm (30 inches), defined slightly differently
Client requirements
Basement, floors: basement + ground floor + attic living space
Number of people, age: currently 3 people (2 adults + 1 child). Planning should include child #2.
Space requirements on ground and upper floors
Office: family use or home office?
Overnight guests per year: not relevant, occasional
Open or closed layout: rather open
Conservative or modern design: rather modern
Open kitchen, kitchen island: yes, kitchen island if possible
Number of dining seats
Fireplace: currently under discussion
Balcony, roof terrace: terrace facing south + terrace facing west planned
Garage, carport: 1 garage, with space next to it for carport / garage (optional, future)
House design
Who designed it: general contractor from the area
What do you like especially? Why? Open living area. All requirements accommodated. Option for a second garage.
What don’t you like? Why? Currently considering removing the second bathroom in the attic and instead adding a shower on the ground floor.
Price estimate according to architect/planner: 500,000 excluding land, additional costs, civil engineering, and landscaping.
Preferred heating technology: heat pump
If you have to give up something, which details / extensions
- can you give up: separate bathroom for the children in the attic
- can’t you give up: open living area, large bathroom upstairs
Why is the design like this? It is the first design from the contractor. Other plans were partly similar.

That’s just how basements are, right? Basements are one thing, lowering a basement by almost half a story is a whole different matter.

What exactly is that iron rod near the driveway? That’s probably a survey marker (for the survey itself; the relevant reference point is marked separately here).

If the manhole cover is the reference point, what is it used for? Most likely for the eave and ridge height measurements of the properties, since it’s closer to the ones in question than some of the other markers. So it also applies to the original poster’s property, while the neighbor to the left uses a different one.

Please provide the development plan. With such selective information, it’s hard to make use of it. I don’t have much more information. What details are missing?
In my opinion, the garage/carport should be on the east boundary, since it is already 1.11m (3 ft 7.7 inches) higher there. Placing the house as close to the street as possible also helps reduce costs. Designing the house narrow also helps. I actually like the idea of the garage/carport on the east side as well. We had it on the west because we wanted a balcony there, but we’ll have to reconsider that. The advantage of the elevation difference should definitely not be underestimated.
Probably refers to the eave and ridge height specifications of the properties, which he is closer to than one of his colleagues. So also for the roof heights of the original poster’s property, while the neighbor on the left side has the other colleague. Where can I find the requirements for the eave and ridge heights? Are those usually included in the development plan/planning permission?
