Dear forum community,

just newly registered after months of reading and I would already appreciate your feedback. We have signed the contract for a new single-family house in northern Hesse and have had preliminary floor plans created based on our ideas.

Development plan/restrictions
Plot size: 578m² (6,225 sq ft)
Slope: 3m (10 ft) height difference sloping from north to south
Site coverage ratio: 0.4
Floor area ratio: 0.8
Building zone, building line, and boundary: all according to HBO
Number of stories: 2 full floors
Maximum average ridge height: 10.0m (33 ft)

Client requirements
Style, roof type, building type: hipped roof
Basement: no
Stories: 2 full floors
Number of occupants: 2 adults mid/late 30s, 2 children “in planning”
Space requirements on ground floor: living, dining, kitchen, study, utility room, guest toilet; upper floor: adult bedroom, child 1 + 2, bathroom, possibly hobby/storage room.
Office: used by one adult
Overnight guests per year = few
Open kitchen: yes
Number of dining seats: 6 – 8
Fireplace: no
Music/stereo wall: no
Balcony: yes
Carport: yes

House design
Who designed it:
- Ideas DIY, plan by prefab house provider
What do we like most? dining table in the bay window overlooking the garden
What do we dislike? hallway on the ground floor is very long (?), little storage space
Price estimate according to architect/planner: €390,000 (KFW40+ house)
Personal budget limit for house including fittings: €450,000
Preferred heating technology: air-to-water heat pump

Why is the design like it is now?
Our ideas were:
- open living/dining area with open kitchen
- lots of light in the living/dining area with large sliding door to the garden
- guest toilet including shower
- adult bedroom with 3.30m (11 ft) wall for our wardrobe, which we would like to keep
- access to balcony from adult bedroom
- no adjoining walls between adult bedroom and children’s rooms
- shower/toilet plumbing not running in a wall adjacent to a bedroom

What is the most important/fundamental question about the floor plan summarized in 130 characters?
We would appreciate any general suggestions/ideas/criticism to improve the floor plan.

The final architect meeting with the prefab house provider is scheduled for December. Until then, we would like to make good use of the time and contribute ideas if useful.

The idea is to position the house in the northeast corner of the plot with a 3m (10 ft) distance to the property boundary so that the garden faces southwest. Due to the slope, there is a beautiful view southwest over the village to the church. To the west is a horse farm, so not the nearest house either.

Best regards,
Steffi

This is something you build on a hillside.
Exactly, unfortunately: a classic example of a house on flat terrain with a basement apartment pushed underneath the distant view terrace.

Quite possible, since there was only a mailbox up there.
However, I would also like to be able to use this "barracks" on my own. 😉

I am quite surprised that the development plan actually allows for a ground floor plus an upper floor. On sloped sites, I am familiar with the practice where houses at higher elevations are also built taller (usually flatter at the top), meaning ground floor plus upper floor; those at mid-level would then have a ground floor plus attic with a steeper roof and an additional basement that is open on one side; and at the lowest level, a basement plus ground floor with a flatter roof. All these building styles involve two-story construction.

However, if the development area is exclusively built by a timber frame contractor, they naturally would not recommend a basement. In that case, something must have gone wrong during the allocation of the building plots.

In our case, though, two homeowners hired a local company to build the basement and then had a timber frame house erected on top. Both turned out well.

The basement level is a money pit full of unnecessary compromises.
