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)

Number of people, ages – 33, 29, <1 planned, planned
Space requirements on ground floor / upper floor // rooms

  • Separated sleeping area accessed through hallway
  • Central kitchen with island and access to terrace and roof windows, kitchen separable from living area with sliding door
  • Children’s rooms all roughly equal in size (with possibility for bunk beds thanks to exposed roof beams)
  • Technical and utility room: air-to-water heat pump, photovoltaics, battery storage, washing machine, and all other necessary connections/distribution (well away from main living areas)
  • Office: soundproofed area

Office use: family or home office? – both, current home office not necessary but possibly in future

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
Frennie

Cool, this reminds me of a book I got as a teenager—full of American houses and floor plans 🙂
Do you have one like that too?

It’s like with a sump pump system that you try to save on, only to realize later that having a basement at ground level is problematic because the landscaping ends up costing even more 😉

I grew up in the USA but have been living in Germany for over 15 years. For love’s sake. My relatives are always surprised at how it’s possible to live in such small apartments like ours 🙂

How was it again?... later having to swap the houses with a low loader so that each fits the plot properly ;-)

The OP @Frennie apparently wasn't interested in the feedback... has checked back here many times but hasn't responded...

Clearly.
Let me say right away: No, we don’t want to put you down! We want to help you so you don’t risk building such nonsense and throwing your money away, and so something like this (sorry @Machu Picchu) doesn’t happen to you:

Good evening!
Thank you all for the quick and, above all, honest feedback. That’s exactly why we signed up!

Kitchen and guest area as a passage and hallway for all family members who want to retreat – that’s more bad than good.

The idea behind this is that the cooking/dining area serves as the central space where most daily activities take place. If you want to avoid the kitchen being a walk-through room, the alternative would be a narrow, windowless, and rather long corridor to reach all other rooms.
ypg schrieb:

Shower in the guest bathroom, why? [...] And some areas just don’t work, like bathtub/shower

In case mornings become hectic with five people, this provides an alternative. But a good point – certainly an option to repurpose about 2sqm (22 sq ft). The bathroom is shown unfavorably in the picture. However, 10sqm (108 sq ft) should be enough to accommodate everything.

Living room for 5 people as a walk-through room to the office, which is supposed to be private?

I am not quite sure if you are bothered by access to the office here or the overall location? Feel free to suggest an alternative location where the office would be better placed.

Bedroom width, table length only for 2 chairs in 2/2.5 meter length

Please explain in more detail what exactly you mean. A bedroom width of 3.30m (11 ft) should be sufficient. We currently have a 1.80m (6 ft) bed, so there is still 0.75m (2 ft 6 in) of space on each side.

Before things escalate further… Detailed answers—and you deserve those—will usually come in the evening. Until then, work and our daughter come first! But that doesn’t stop us from following the thread and reading along.

More to follow 😉

That is basically a good idea, but as it has been implemented, there is hardly any kitchen space, and the table is drawn in too optimistically.

Is there actually a site plan with elevation points?

That is optimistic... 330 cm (11 feet) in the shell construction might be about 325 cm (10 feet 8 inches) finished. And a 180 cm (5 feet 11 inches) bed is probably the mattress width, but the overall bed width is often a bit more.
