Hello everyone,
We have been planning our own home for about a year now and have gone through many iterations (from basement to two-story, etc.). In the end, we want to build a bungalow and would appreciate some critical feedback and suggestions. So far, we have created the floor plan ourselves, but we will hand it over to the building company afterward. Thank you!
Development Plan / Restrictions
Plot size – 1,056 sqm (0.26 acres)
Slope – 2 m (6.6 ft) drop over 35 m (115 ft)
Site coverage ratio – 0.4 (according to §17 Federal Land Utilization Ordinance WR)
Floor area ratio – 1.2 (according to §17 Federal Land Utilization Ordinance WR)
Building setback line and boundaries – 4 m (13 ft) from property line
Adjacent development – NW, N, NE
Number of parking spaces – 2
Number of floors – 1
Roof style – gable or hipped roof with two small dormers + triangular windows facing SW
Architectural style – bungalow, because the plot is large enough, children within sight and hearing range, barrier-free possible
Orientation – SW (like neighboring houses)
Maximum heights / restrictions – 9 m (30 ft) height / 4 m (13 ft) to neighboring properties
Other specifications – roof pitch 25-40°
Owners’ Requirements
Style, roof form, building type – timber frame construction, bungalow with exposed roof beams in living and bedrooms (except entrance area + technical room, possibly to create storage space)
Basement, floors – no basement
Number of people, ages – 33, 29, <1 planned, planned
Space requirements on ground floor / upper floor // rooms
Office use: family or home office? – both, current home office not necessary but possibly in future
Guests per year – 6
Open or closed architecture – closed
Traditional or modern style – modern
Open kitchen, kitchen island – kitchen island and separable kitchen with sliding door
Number of dining seats – 6-8
Fireplace – no
Music / stereo wall – no
Balcony, roof terrace – covered terrace between dormers
Garage, carport – garage (not prefab – timber frame with gable roof as additional storage area) with adjacent shed/workshop
Kitchen garden, greenhouse – kitchen garden
Other wishes / special features / daily routine, including reasons why something should or should not be included
- Living area should not exceed 155 sqm (1,668 sq ft) (cost factor)
House Design
Who created the plan – do-it-yourself – floor plan DIY
What do you like in particular? Why? – separation of living and sleeping areas, covered terrace and entrance, small dormers and high ceilings due to exposed roof beams
What do you dislike? Why? – possibly the office is too small? Technical/utility room large enough
Personal price limit including equipment: 500,000 €
Preferred heating system: photovoltaics + battery with air-to-water heat pump + underfloor heating
If you have to give up certain features / expansions
-can you do without: actually all rooms should be as planned
-can’t do without: -
Why is the design as it is now? For example
After many iterations with a draftsman from a construction company and different styles (single-family house with two floors, with or without basement), we tried to fit all our wishes ourselves into one floor plan.
What do you think makes it particularly good or bad? – That’s the question for you 😉
What is the most important / fundamental question about the floor plan summarized in 130 characters?
Critical feedback, thoughts, and suggestions regarding major issues, feasibility, and practicality.
Best regards

the mini-splitNo mini-split. Just a simple slab-on-grade house… right, Katja?ypg schrieb:
By the way: do you both reply using the same account?Yes, we do. Otherwise, it would probably be confusing for other readers.
Actually, two concrete slabs were planned here. The idea is to soften the moderate slope a bit without having to create a real split-level foundation. Maybe it’s cheaper to just do one slab and simply pour more screed in the upper area? Depending on what is more cost-effective.
I added a bit to the exterior dimensions because the knee wall at the top takes up a lot of space. I need to measure tomorrow. I’m about to go to bed now...

You should hire a surveyor I generally think that’s a good idea 😉 Just kidding, but seriously, a topographic survey is always useful, whether for the building permit / planning permission, a potential architect, or others involved.

There is a special tool, like a hose or something, to measure elevations. That tool is called a water level. It’s basically just a hose filled with water. I believe there are some good videos about it on YouTube.
As a surveyor, my question is whether you need the absolute elevation (above sea level). That’s not easy to get without a professional surveyor. For a surveyor, it’s a routine job. You can expect to pay around 300 to 500 euros, but the survey will be very useful.

It should cost around 300-500€ (approx. $320–$530). With the survey plan, you can do a lot. Hiring a surveyor does indeed sound like a good investment! We will move forward with that.

@K a t j a, I remember that your sketches were roughly 100 + 80 square meters, which could be reduced by about 10 square meters with some careful adjustments.
Do you think this approach would fit better within our budget compared to the bungalow mentioned at the beginning?Well, that’s a good question. The expensive part of building on a slope compared to a flat plot is the earthworks. If you want to place a large flat area on a sloped terrain, you have to move much more fill material back and forth than if the area is smaller. That makes sense. Then there are the many retaining structures, which aren’t cheap either. The more you build into the slope, the less you have to move and support the earth. But you’ll probably never avoid it completely. The roof is also a major cost factor for the bungalow. It’s simply huge. Two floors need only about half the roof area (roughly speaking). A staircase is also cheaper than two separate roofs. The question for you is also: what do you really need? 155 square meters for five people is rather tight, especially if you need an office as well. Yvonne nicely calculated that in #48. You basically need 180 square meters. A 155 square meter bungalow will probably end up costing you just as much or more than a 180 square meter one-and-a-half-story house. Prices are currently very unstable, but it feels like you’re about 100K short – no matter what you build. It only gets cheaper if you reduce your wish list. I also have to ask quite bluntly: if the budget is already tight now, how will it be with three kids? I have my doubts.
Ultimately, we can’t tell you what the local companies will charge. The only way is to ask. 😉
