ᐅ Floor Plan of a Two-Story House on a Gentle Slope

Hello.

I have a plot of land with a slight slope; the height difference from the front to the back is about 1.5m (5 feet).

For cost reasons, I would prefer to forgo a basement and have as much as possible on the ground floor level. The upper floor is intended to be used either by the children or possibly rented out later, depending on what the children decide to do.

I expect that building upwards with an additional upper floor will provide more flexibility than building downwards with a basement, which is usually less pleasant to live in compared to the same area at ground level.

A large double garage will be built on the east boundary. The neighboring property on that side only has frosted bathroom windows, and the owner (a relative) has also agreed to an easement if the garage is somewhat larger.

Development Plan / Restrictions
Plot size: 814m² (8,761 sq ft)
Slope: approx. 1.5m (5 feet) across the entire area
Floor area ratio (FAR): 0.4
Plot ratio / floor space index: 0.7
Maximum number of floors: 2
Roof style: gable, 30 degrees
Ridge orientation: east to west
Maximum heights / limits: none, the development plan dates from 1980, and various roof and building shapes can be found in this area

Owner Requirements
Style, roof shape, building type: definitely no flat roof, no bay windows or dormers
Preferably solid construction (masonry)
Guest toilet on every floor
Basement still undecided, 2 floors possible
Walk-in (level-access) shower preferred, bathtub not necessary

Flexible use for one large or two small families in the future should be possible.

House Design
Based on consultation with a licensed general contractor (GC) from the region

The shell construction will be provided by the contractor, while I will do the interior finishing myself, including electrical work, plumbing, water installations, flooring, interior plastering, etc., as I am a professional. I plan to organize and subcontract the remaining work to experienced local companies.

There is no rush, so the complete interior finishing can take some time.

Preferred heating technology:
District heating connection supplied 100% with renewable energy

Why does the design look the way it does?
The design was created by the architect after consultation based on our ideas.

What do you think of the design? What would you change?

Since the terrain needs to be adjusted and the foundation slab filled to compensate for the slight slope, how much would you estimate the additional cost for a basement? The planner suggests that a basement should be considered with a height difference between 1.5m and 2m (5 to 6.5 feet).

Do you have any other thoughts? Once you commit to a design, it’s easy to become a bit blind to alternatives...

Thank you and best regards!

With the new orientation, the lowest point of the property/house is about 40 cm (16 inches) higher.

In my opinion, the neighbor already has a tall hedge acting as a privacy screen.

You will then have a fairly well-protected garden on the north side.

How have the neighbors shaped their land?

Please take some photos of the property boundaries on the west and east sides. This way, we can see how the neighbors have designed their property borders.

but why so far from the street? That’s quite a long driveway / paving, which also increases the overall cost.
We have a similar sloped site.

The building envelope doesn’t allow much flexibility on the south side.

Slope from southeast to northwest is 5%.

When I compare the status of https://www.hausbau-forum.de/threads/einschaetzung-kosten-fuer-rohbau-und-gesamtkosten-putz-estrich.46290/ with the initial post here, I see such strong similarities that it is difficult for me to understand the purpose of all the suggestions provided in the meantime :-(

Hello.

Inspired by another design, I created an alternative floor plan for the ground floor using Corel Draw, experimenting with different staircase positions.

The goal of the design was to achieve a better separation between "public and private" areas, and to include a space accessible from the garage for storing shoes and clothes.

The utility room, with 7m² (75 sq ft), is intended to be barrier-free and may also accommodate a washing machine and dryer. The electrical panel is planned to be located there as well.

The district heating transfer station will be installed in the basement.

I would simply clone or create a similar layout for the upper floor.

So, it could either accommodate two small families or one large family spread over two floors.

To fit in better with the surrounding buildings and out of consideration for the neighbors, I will shift the house northwards like the others and place the garden on the south side.

What else could be optimized here?

Best regards and thanks!

You seem to prefer ignoring well-intended advice. You have still violated the building boundaries. First, clarify where the house can be placed.

Here is my suggestion that complies with the building envelope.
