Hello everyone,
we have just purchased a plot of land and I have created my first floor plan. I would appreciate your feedback and criticism.

Development Plan/Restrictions
Plot size: 639 m² (6875 sq ft)
Slope: 1 m (3.3 ft) decline over 18 m (59 ft)
Floor area ratio (FAR): 0.4
Plot ratio: 0.8
Building envelope, building line and boundary: 20 m x 15 m (66 ft x 49 ft) (minus 3 m (10 ft) to the neighboring boundary)
Edge development: no
Number of parking spaces/garage: 2 (unfortunately not allowed outside the buildable plot area)
Number of floors: max. 2
Knee wall height: for single-story construction: 0.8 m (2.6 ft)
Roof type: gable, hip, half-hip roof
Orientation: south
Maximum heights/limits: eaves height max. 4.5 m (15 ft) for one floor and 6.5 m (21 ft) for two floors

Owners’ Requirements
Style, roof shape, building type: bungalow, gable roof (to possibly use the attic later)

Number of dining seats: 4
Fireplace: yes
Balcony, roof terrace: no
Garage, carport: 2-car garage
Utility garden, greenhouse: no
Additional wishes/special features/daily routine, also reasons why or why not

House Design
Who designed it: do-it-yourself
What do you especially like? Why? All living spaces on one level
What do you dislike? Why? Stair position, hallway, kitchen, dining, living area. The kitchen, dining, and living area feels “cramped” to me.
Attic: expandable if needed
Is the plot available: yes
Personal price limit for the house: max. €450,000 (approx. $490,000) including basement, excavation, floor, walls, plumbing (I am still unsure whether basement and excavation count as additional house costs, so stated as overall sum)
Kitchen: €20,000 (approx. $22,000)
Double garage including foundation: €18,000 (approx. $19,500)
Preferred heating technology: ground-source heat pump or air-source heat pump (depending on price), solar thermal, photovoltaic (due to subsidies)

If you had to give up some details/extra features
- Could you give up: fireplace
- Could not give up: basement (a partial basement would be acceptable due to size, but unsure if that would be much cheaper)

Why has the design ended up like this?
House building forum, internet

Because of the building envelope of 20 m (66 ft) minus 6 m (20 ft) garage, only 14 m (46 ft) remain for the house. Although I really believe that we will never be able to build the house for this price. There is an old 100 m² (1075 sq ft) bungalow with a partial basement on the plot, demolition has been budgeted at €25,000 (approx. $27,000) (not included above), hopefully this will make the necessary excavation work somewhat cheaper...
As an alternative, we are considering building a “boring” two-story townhouse with 10 m x 10 m (33 ft x 33 ft) footprint (complaining on a high level).
Basement and attic are roughly sketched only, just done for the staircase.

Our family experience with bungalows and basements is that basements always end up getting filled, and 90% of the stuff and old furniture stored there is never brought back upstairs.
That’s why we decided to build a slightly larger bungalow of 125m² (1,345 sq ft) without a basement.
Over the course of 15 years, the basement gets full.

No problem, then just mark your calendar for twelve years from now to start decluttering 🙂

Setback areas must still be observed in my opinion, even if the building envelope allows otherwise. 2.5 m (8 feet) is too little.

The driveway to the garage is also too short. In my opinion, it needs to be 5 m (16 feet). Or does the zoning plan say something different?

Hmm, I’ve positioned the garages at the edge of the building envelope, which is about 4.3 m (14 feet) from the street. I might have to move them back a bit. The development plan only states that garages outside the building envelope are not permitted, but that doesn’t mean other regulations don’t apply.
The boundary to the (only) neighboring property is 4 m (13 feet), which should be okay. The 2.5 m (8 feet) refers to the distance to the street, and there is already an existing bungalow there. But that doesn’t mean I’m allowed to build the same way again.
Thanks for the pointers, I’ll add them to my list of questions.

In most federal states, the setback is 3 m (10 feet) or half the building height, but this can extend up to the centerline of public roads. Therefore, a building window line drawn at only 2.5 m (8 feet) from the property boundary is not necessarily contradictory. Many regional building codes require garages to have a 5 m (16 feet) setback in front of the door, so the distance between the garage and the street also depends on which side the driveway is located.
