ᐅ Single-family house, 150 sqm, Lower Saxony

Hello everyone,

After following this forum for what feels like forever, I finally have to “lay all my cards on the table.” Some time ago, we bought a plot of land in rural Lower Saxony right next to our current apartment, and now we want to slowly but surely start the house building process.

I’ve filled out the questionnaire as much as possible. For roof style, number of floors, building setback lines, etc., I only have information from an old preliminary building inquiry made by the previous owner of the land. However, a lot has changed since then (several houses with two full floors, etc.), so I can well imagine that two full floors won’t be a problem.

I’ve attached the floor plans for the ground floor (GF) and upper floor (UF), as well as a relevant excerpt from Google Maps. The two floor plans are not oriented to north, so I added a north arrow there. The Google Maps image is oriented north. The red frame roughly marks the property. The small red box on the street marks the lowered curb for the driveway access. The larger red box roughly indicates the area where the house including the carport is planned to be located. I hope this is enough for now?

Zoning Plan / Restrictions
Plot size: 1978 sqm (about 0.49 acres)
Slope: No
Building setback lines and building boundaries: 6.0 and 19.0 m (about 20 and 62 feet) from the street-side property boundary (still being clarified, a lot has changed recently)
Number of floors: 1.5 or 2 (still being clarified, a lot has changed recently)
Roof style: Gable roof

Homeowners’ Requirements

Room requirements on GF, UF:
GF: Kitchen with dining area, living room (can be separated), office, guest bathroom with shower, utility room, small storage space
UF: 2 children’s bedrooms, bathroom, storage room, master bedroom
Office: Family use or home office? Home office
Number of overnight guests per year: Negligible

Garage, carport: Carport for one car and possibly a simple parking space in front of the house (cars are for us purely practical items)
Kitchen garden, greenhouse: Unclear
Other: The kitchen island is intentionally only 1 meter (39 inches) deep. This seems like a comfortable depth for us since both of us can easily reach the far end (we’re both not very tall, about 170 cm (5’7”), and we tested by placing a 1-meter-wide wooden board on our current countertop). A nice side effect is that this frees up more space for the dining table. Overall, we still plan to discuss the kitchen layout further in the other forum.

House Design
Who designed the plan: Do-it-yourself with the probably usual approach (we looked at many floor plans from friends and prefab house providers)
What do you like most and why? We’re quite happy with the design. We really like the sliding door in the dining area and the large window in the living room because of the direct connection between garden and indoors. The sliding door between living and dining rooms allows retreat to the living room when guests are over (it’s not a big deal that you still have to walk through the dining area). The staircase should be separated from the living space but not located in a direct dirt/splash zone. The children’s rooms are sufficiently large and have south-facing windows overlooking the garden.
What do you dislike and why? We’re still tinkering with the exterior and window positions. Especially upstairs, the window layout is far from finalized. For the stairs, I grabbed a floor plan from a stair builder that fits (concrete stairs); I hope the dimensions are also realistic in real life?
Personal budget for the house including fittings: 300k, the average price per square meter given by our banking contact pretty much matches the costs of several friends currently building (rural Lower Saxony, about 1650 - 1850 €/sqm)
Preferred heating system: Heat pump with horizontal loop collector

If you had to give up anything, which details / features could you do without?
- Could do without: Honestly, not much
- Cannot do without: Office, sliding door, kitchen island

Why does the design look like it does now?
We looked at many floor plans from friends and prefab house suppliers. Changing existing plans mostly didn’t help, so in the end we spent nights drawing our own plans (which is fun, anyway).
What do you think makes it particularly good or bad?
We managed to fit our entire room program into our limit of about 150 sqm (about 1,615 sq ft). When mentally going through our typical day, the floor plan works quite well and all rooms seem sufficiently sized.

What is the most important / fundamental question about the floor plan summed up in 130 characters?
Since we are still happy with it after letting it “sit for a while and reviewing it again,” the question naturally arises whether we have overlooked something fundamental. Does anything stand out as a problem that wouldn’t work? Something we would regret for the next 30 years? More specifically: is the kitchen with the dining area too narrow or too long and narrow?

I look forward to hopefully plenty of feedback.

Thanks in advance!
