Dear Homebuilding Forum,
As a newcomer to your group, here is the completed profile of our building project:
Development Plan / Restrictions
Plot size: 637sqm (6860 sq ft)
Slope: no, completely flat
Site coverage ratio: 0.4
Floor area ratio: 0.8
Building window, building line and boundary: street frontage 17.6m (58 ft), 3m (10 ft) setback on left and right sides, building window 11.6m (38 ft) wide x 12.5m (41 ft) deep
Adjacent buildings: single-family houses
Number of parking spaces: two possible
Number of floors: 2 full stories plus 1 setback floor with flat roof (minimum 1m (3 ft) recess on all four sides)
Roof type: gable roof & flat roof
Architectural style: many options allowed as long as aligned with design guidelines
Orientation: south-facing
Maximum height/limits: 9m (30 ft)
Other requirements
Homeowners’ Requirements
Style, roof form, building type: simple, timeless, flat roof, cube-shaped
Basement, floors: basement, ground floor, 1st floor, 2nd floor as setback level
Number of people, ages: 2 adults, 4 children between 1 and 6 years
Space requirements ground floor, upper floors: ground floor approx. 105-110sqm (1130-1180 sq ft), 1st floor approx. 100-105sqm (1080-1130 sq ft), 2nd floor approx. 40-45sqm (430-480 sq ft)
Office: family use or home office? 1 home office
Guest bedrooms per year: very rare
Open or closed architecture: open concept
Conservative or modern construction: conservative design
Open kitchen, kitchen island: open kitchen with island
Number of dining seats: at least 6, extendable to 8-9
Fireplace: maybe, but chimney routing is a bit complicated
Music/stereo wall: no
Balcony, roof terrace: balcony on 1st floor to soften the building volume, possibly a roof terrace on the 2nd floor if not too complicated
Garage, carport: originally planned garage on one side including storage and carport on the other side, now tend to only carport as garage affects overall appearance
Utility garden, greenhouse: kindergarten ;-)
Other wishes/special features/daily routine, also reasons for why this or that should or should not be included
House Design
Who designed it:
Do-it-Yourself
What do you like most and why?
That it was possible to arrange spacious children’s rooms and create space for two bathrooms. Public living areas on the ground floor, children’s floor on the 1st floor, and parents’ area on the 2nd floor.
What do you like least and why?
I’m uncertain about the positioning of the bathrooms relative to each other (complexity due to drainage pipes), and which staircase best serves the 1st floor layout. The building volume is still not ideal, but I have no further ideas on how to meet the zoning requirements.
Price estimate according to architect/planner: 640,000 EUR
Personal price limit for the house including fittings: approx. 700,000 EUR
Preferred heating system: geothermal
If you have to give up something, which details or extensions
- can you do without: additional room in the setback floor, terrace in the setback floor, already gave up on double garage as it overly restricted the floor plan :-( possibly external basement stairs
- cannot do without: 4 large children’s/teenage rooms, setback floor because we can’t fit all rooms on just 2 floors, basement as a lot of stuff accumulates with 4 children...
Why is the design like it is now? For example:
Because after many nights of planning I couldn’t come up with a better solution...
What makes it in your opinion particularly good or bad?
It meets our requirements on paper, but I lack the experience to judge whether it will work well in practice, which is why I’m asking for your opinions.
What is the most important/basic question about the floor plan in 130 characters?
How can I best organize the living space (especially but not only the 1st floor) and use the proper staircase design to create a spacious hallway without wasting area?
That was quite a bit of work ;-) I hope this information is useful for the further discussion.
In the next post I’ll share the floor plans and some exterior views (if I manage the attachments...)
Thank you in advance for your time reviewing this and for your honest and constructive feedback on the current design!
Best regards
Stephan

Wall construction: We’re planning for KfW55 standard with 17.5cm (7 inches) calcium silicate blocks plus 14cm (5.5 inches) external thermal insulation composite system (ETICS) = 31.5cm (12.4 inches) total. That’s not much less than a monolithic wall using 36cm (14 inches) blocks, which I would also find appealing. The general contractor, however, isn’t particularly keen on this (among other reasons, due to load-bearing and soundproofing concerns)... I understand this question can’t be answered universally because of energy calculations, window areas, etc., but maybe you have some ideas: What other wall constructions do you see as possible to reach at least KfW55 standard without significantly increasing the wall thickness? Keep in mind "Des 11anten Steinemantra" (also recently available at baulotse-hoffmann punkt de). Use the wall construction that the builder has the most experience with. Everything else is secondary, as Rolf Miller aptly puts it.

Subsequent division into two or three units. Unfortunately, our current staircase design is only somewhat suitable for dividing the house later into multiple units. Do you have any spontaneous ideas on how this could be achieved? With a six-year-old and a one-year-old, my clear solution would be: simply sell the entire house once the kids have all moved out for university. Then the house will be at a desirable age, and in the niche market of “houses for families with four children,” you’ll best know how quickly properties sell.

Nice to see the story continuing. The drawing style of the design looks familiar to me. 😉 Yes, I think so too! Thanks to your puzzle from 5 months ago :-) thanks again for your tip! So far, a complete success story! Regards, Stephan

How critical do you consider a stairwell without natural light (except through windows on the second floor)?In general, having a staircase as a “dark hole” is obviously not ideal, but I think in your case it won’t be too bad. You also have options to improve the overall situation, for example by partially opening up the lower staircase area by shortening the adjacent wall or balustrade. If you then widen the first two steps, the staircase will integrate better into the hallway and feel more open with more angled natural light coming in. This should work on the ground and upper floors. On the upper floor, this would also have the added benefit of reducing the tunnel-like impression in the children's bathroom.ypg schrieb:
Are all the basement rooms finished?What exactly do you mean by "finished"? Finished as in unnecessary? How do you come to that conclusion? Because of the room layout? Regards, Stephan
