Hello everyone,
attached is our project with a request for suggestions for improvement, especially regarding the interior layout. The building permit application is currently in process, so please avoid complete redesign proposals for the building envelope, entrance, etc. Doors and walls can still be adjusted inside.
And yes, we are fully aware that this is a small constrained plot with limited garden space, but this is all we have here and we’re happy with it!
Development Plan/Restrictions
Plot size: 310 m2 (3,337 sq ft)
Number of parking spaces: 2
Number of floors: 1.5–2
Roof type: 45-degree gable roof
Orientation: SW
Additional requirements: Must be attached to neighbors and adapted accordingly. Changes to roof shape, knee wall height, number of floors, etc. are not possible!
Owners’ Requirements
Style, roof type, building type: Attached house, adapted to neighbors. This is restricted. Open floor plan. Flexible for aging occupants.
Basement, floors: Basement = self-contained apartment according to regional building codes, with separate entrance for permanent rental in the basement.
Number of occupants, ages: 2 adults + 2 children (4 and 1 year old), basement apartment: either 2 people or a shared office for 2 to max. 6 people
Space requirements on ground and upper floors: at least 120 m2 (1,292 sq ft). We have 165 m2 (1,776 sq ft) + 18 m2 (194 sq ft), so more than needed.
Office: Family use or home office? All three desired. One mixed-use room for home office and guests planned on the ground floor.
Guest sleepers per year: maximum 2, 1–3 times per year
Modern construction style
Open kitchen, kitchen island: possibly
Number of dining seats: 1
Fireplace: no
Balcony: yes, roof terrace: no due to neighbors
Garage, carport: no, only 2 parking spaces and storage rooms on the floors. One parking space will be realized with grass pavers and a sliding gate so that the garden visually appears larger.
House Design
Who designed the plan: 2 years of our own planning, final design approved by an architect as feasible.
- Planner from a construction company: yes
- Architect: yes
What do you particularly like? Why: We planned 3 separate living units so that we can live on the ground floor as we get older and the kids move upstairs or we can rent it out. A barrier-free ground floor was very important to us. In case of emergency, we can also rent out the ground and upper floors. Only the basement apartment is planned for rental; ground and upper floors for own use.
Estimated cost according to architect/planner: approx. 1 million €
Preferred heating system: Air-to-water heat pump, split system for cost reasons. 8 kWp solar system, 2 centralized ventilation systems. Basement made of concrete + Styrodur insulation, ground and upper floors with Poroton T7-MW 36.5 bricks. Soundproofing and increased living space were priorities, and unfortunately, we no longer qualify for KfW40+ funding. We simply didn’t have enough time for the KfW40+ NH standard because interest rates have risen sharply.
If you have to give up something, which details or expansions?
- Can give up: definitely the garage. We don’t own a car and use car sharing, which works well for the family. We can occasionally use a garage and shed on the neighboring property.
- Cannot give up: terrace, garden, balcony
Why is the design as it is now?
For example, standard design from planner? No, everything developed by us. Strong restrictions due to attachment to neighbors and limits on ridge height, roof shape, and height of the adjoining building. “Wish for” options are hardly possible here since the house must be attached to the neighbor.
Which wishes did the architect implement? Most of them.
What do you think makes it particularly good or bad? We have a very small plot and limited freedom in terms of shape, but in our opinion, we made the best of it. For cost reasons, we omitted Gutex insulation in the roof. We only have the attic peak, the bathroom, and one room with a sloping ceiling (knee wall height 1.38 m (4 ft 6 in)).
According to the site manager, this should not lead to extreme overheating, but we might still install it depending on feedback. The attic is open and connected to the ventilation system, so air in the basement will be mixed via the heat exchanger anyway. My parents also don’t have Gutex insulation in their prefab home from the 1980s, and yes, the attic gets quite warm but not over 35°C (95°F). We planned to compensate with blinds but are still unsure.
Additionally, we plan to convert the kitchen on the ground floor into a living room as we age and relocate the kitchen accordingly. Everything is optional, and planned with flexible plumbing. In the basement, we might still plan another room but are unsure of the location.
What is the most important/basic question about the floor plan in 130 characters?
Is the size of the bathroom and hallway sufficient, or should we have it adjusted?
In the basement, we will add a south-facing window on the left side to brighten the basement apartment. This will reduce privacy and garden space but should please the basement occupants.

but here there were no suggestions, just complaints 🙂There will never be any with this kind of vague guessing. If you think we’re going to throw 100 plans at you to choose from, you’re mistaken. A floor plan is an iterative process that starts with a detailed needs analysis combined with your wishes. Since these often change or sometimes become unrealistic, no one takes you or your project seriously anymore.I get the feeling you’re afraid to commit, which is something you have to do when building a house. Maybe it would be better if you stay in your apartment and keep your money. That way you can always decide flexibly to move and live differently.

Bertram10030 Aug 2022 15:29You should definitely plan ahead so that the basement can also be converted to be drive-in accessible. 😎 This way, the bulky basement space can still be properly used as a garage. Upstairs, everything can probably be converted somehow into a great single-family home, but it would be a shame not to be able to use the basement properly as well.

And here’s my quick suggestion based on Katja’s basement (windows slightly modified, since that’s allowed)
... although I wonder how you would actually drive to the parking spaces ...I liked it too and used most of it for the basement level. I just find the bathroom placement unfortunate. This way, any guest who needs to use the restroom has to go through your bedroom. Let’s see what Katja thinks about that.medow1982 schrieb:
I have discussed the project costs objectively. @katja, what do you think about #57?I assume you mean #63. At least that’s the number I see. But we’ve already had this issue where everyone sees a different number...About the design:
The pantry takes up important (natural light) space that should be allocated to the kitchen. The kitchen is unnecessarily small. Bathroom layout is poor. The chill-out area remains too cramped and is still in the hallway traffic area.

medow198230 Aug 2022 15:39#63 was correct. I only arranged the bathroom to give an idea of the size. What isn’t working here, or how should the toilet, bathtub, shower, and sink be arranged so that it’s not a problem for you?
