Hello everyone,

we are still in the planning phase of our single-family house and have been experimenting a bit with a freeware floor plan program. We would like to get your feedback.

But first, the questionnaire:

Development plan/restrictions
Plot size: 440m² (4,736 sq ft)
Slope: approx. 2m (6.6 ft) over 20m (66 ft) to the east and approx. 2m (6.6 ft) over 20m (66 ft) to the south
Floor area ratio: no development plan available, building according to §34 Baugesetzbuch (German federal building code), so floor area ratio 0.4
Floor space index: see above: 1.2
Buildable area boundaries: north (toward street): approx. 2m (6.6 ft), west: 3m (10 ft), south: 3m (10 ft), east: 6m (20 ft) to the immediately adjacent neighbor’s building, otherwise 3m (10 ft)
Edge development: yes, neighbor to the east
Parking spaces: 2 in garage and 2 in front of garage for guests
Stories: 2 full floors
Roof type: hipped roof (all types are permitted)
Architectural style: modern (all styles are permitted)
Orientation: garden facing south
Maximum heights/limits: same as neighboring buildings, tall enough
Other requirements: none
Street: very narrow, dead-end

Homeowners’ requirements
Style, roof shape, building type: urban villa with hipped or gabled roof, with at least 2.00m (6.6 ft) knee wall height
Basement, floors: basement, ground floor, and upper floor
Number of occupants, age: currently 2, planned 4
Space requirement ground floor, upper floor: about 60-70 m² (650-750 sq ft)
Office: family use or home office? Both, but mostly private use
Overnight guests per year: a few, possibly longer stays in a few years
Open or closed layout: open
Traditional or modern construction: modern
Open kitchen, cooking island: open kitchen with counter or island
Number of dining places: 4-6
Fireplace: no
Music/stereo wall: standard TV wall
Balcony, roof terrace: no
Garage, carport: double garage with one door
Vegetable garden, greenhouse: standard
Other wishes/special features/daily routine, including reasons why some things are wanted or not: guest room and guest bathroom in basement, laundry room on the upper floor

House design
Who planned it: DIY
What do you especially like? Why?: upper floor bathroom and bedroom facing the garden (near the forest edge), separate entrance area with cloakroom so cats can’t run outside the front door, laundry room on the upper floor
What do you dislike? Why?: bathrooms are not stacked vertically, so the drains are under the living room, but we accept that
Preferred heating system: air-to-water heat pump with or without ventilation system

If you had to give up something, which features or extensions
- can you give up: basically nothing 🙂

Why did the design turn out this way?
We sketched out our specific wishes and then made sure they fit within the built-up space.
What do you think makes it particularly good or bad? I hope it will be comfortable to live in.

What is the most important/fundamental question about the floor plan in 130 characters?
How do you like the floor plan? I’m happy to explain our thinking behind particular features if you have questions.
Would the drains under the living room be very noticeable? I think they might be hidden with furniture (possibly DIY). Those black squares in the drawings indicate drains or ventilation shafts.

I plan to present this design to various general contractors. An architect is not an option for various reasons. Please avoid discussions about why we chose general contractors over an architect.

Due to the neighbor’s building on the boundary and the building authority’s instruction that we keep 6m (20 ft) distance from their house wall, we want to place the garage adjacent to their wall (with appropriate foundations, of course, so no pressure is exerted on their basement wall). The garage is about 1m (3.3 ft) lower than the house to reduce the slope from the street to the garage. That’s why I integrated this corner into the ground floor and basement so one can walk down a few steps from the front door to the garage. Possibly, a passage to the garage could be made at the stairs if the height levels work out. The staircase will be a half-landing staircase, but the program cannot display this. From the front door to the street, no steps are necessary; a ramp should suffice.

In the basement, the utility room and hobby room will have light wells, and the guest room/office and bathroom will have a light court. Guest room and office can be combined; it only needs space for a bed, a wardrobe, and a desk.

We look forward to your suggestions!

Good luck Tortuga123

What we have noticed about this and what we want to include as additional agreements:
- Offer or information regarding photovoltaic system (so we have documentation for financing)
- Planning and approval of the garage (but construction work done by ourselves)
- Window tinting/film
- Electricity supplied from the roof
- Additional bathroom in the basement
- Possibly centralized instead of decentralized ventilation
- Seismic zone 1; access roads and site conditions need to be checked beforehand, any potential difficulties must be factored in and will not be separately compensated
- Washing machine connection on the upper floor
- Shower with seating option and a partition wall longer than 1.20 m (4 feet) (possibly to be clarified on site)
- More electrical outlets (possibly to be coordinated directly with the electrician)
- Heavy-duty power cable to the garage
- Instead of 2 light wells, one light courtyard (electrical)
- Declaration of basement rooms due to building regulations (ventilation, lighting, fire protection, etc.) and calculation of potential additional costs

Costs we are aware of: earthworks, including ring earth electrode, drainage, dimpled membrane, backfilling; garage; outdoor stairs; other landscaping; tiles in the rest of the house except bathrooms; wall sanding and painting

Otherwise, as with other contractors: buffer for selections

We have already done a geotechnical survey (loess clay, no groundwater present).

Do you notice anything seriously important that we might be missing like blind frogs?

Considering the 20 (!) partners with logos mentioned by the construction company, it is somewhat ridiculous that you specifically concealed the name of the general contractor himself. This is also counterproductive, as it prevents users from searching the forum to see what information we have already compiled about this provider here.

I’m off now – and not to Santiago ;-)

Honestly: then goodbye. Whether you find it ridiculous or not doesn’t matter to me. First, I’m supposed to post the scope of work description, then that’s wrong again.

And for everyone else: there has been no information compiled here in the forum about this provider yet. So a forum search isn’t necessary anyway.

Thanks for posting, now the experts here can take a look and check for anything missing...

The structural engineering is included, but not the additional costs that may arise from it, such as more reinforcement or thicker slabs.
Four inspectors are not enough; if in doubt, they work for the client, not for you.
Earthworks are to be done by the builder or involve site preparation.
The electrical plan is still far too basic, more like something from 1960 than 2020.
Floor and wall coverings are missing except for the tiles.
You will need to decide if the overall fittings suit your taste. Everything is listed fairly clearly.
Some builder-supplied items are also included.

I only skimmed through the scope of work, but it’s not the worst.

Four inspections by an expert are too few; if in doubt, they usually work for the client, so not for you.
Earthworks are to be done by the client or as part of site preparation.
The electrical installation is, as always, far too minimal. It’s more like standards from 1960 than from 2020.
Floor and wall coverings are missing, except for the tiles.
Regarding all the fittings, you need to see if you like them. Everything is listed quite thoroughly.
Some client-responsible items are also included.

Hi, yes, we are aware of the specifications.
The electrical installation is minimal, I have already noticed that, but still more than with some others, as I have found out...
The note about additional costs due to structural engineering is helpful, thanks! I will try to inquire about what might come up for us.

I have already joined the Builders’ Protection Association and will order the expert through them. They will probably visit about eight times or so. I would do that with every general contractor anyway.
