ᐅ Separate Apartment for Parents: 210 m² Detached Single-Family House with an 80 m² Self-Contained Apartment

Created on: 22 Apr 2017 18:22

Hello everyone,

We are planning to build a house with a separate apartment for parents.
The main house will have two full stories and a hip roof, and to reduce costs a bit, the separate apartment and the garage will have flat roofs.

The house will be built in a new development, and I have already designed the floor plan.
The plot measures 924 m² (11,470 sq ft) and is numbered 30 on the site plan.
Site coverage ratio: 0.4
Floor area ratio: 0.6
Building height: 4.5 - 6.5 meters (15 - 21 feet)

The driveway can only be on the west side because there will be a bus stop on the south side.

What concerns me:
On the upper floor, the east wall runs right above the living and dining area and is actually only supported by the wall between the stairwell and the storage room of the separate apartment. Could this cause any structural issues?

I have drawn the exterior walls as 45 cm (18 inches) thick and the interior walls as 15 cm (6 inches). Load-bearing walls could probably be reduced to 20-22 cm (8-9 inches).

The “wet rooms” like bathrooms and toilets are spread throughout the house, and the separate apartment will have its own heating system. The sewer drainage gullies are located at the south edge of the plot near the bus stop.

So, if Kerstin were to send you an invoice now, I can understand if you complain that it’s not what you wanted. But she doesn’t do that; she spent one or two evenings giving you a thought-provoking suggestion for a sensible room layout.

Some walls can certainly be moved, even if it’s the exterior wall, so that your wishes for the house front are approximately met. But as 11ant already said: where a circle fits, a square must leave corners.

Anyone who buys a challenging plot must also live with the consequences.

Still, I find the plot quite acceptable; you just need to be open-minded and not too set in your ideas.

Best regards in brief

The more I look at the plan, the more I like it, but it has to please all of us.

Then you should probably look at it even more, because here:

it seems to me that you might be starting to revert back to a worse version.

Oops, did I say that?

How should I picture the bus stop and the plots 42/8 and 42/9?

Here you can see that an older renovated house stands to the right, and the bus stop is marked in yellow.

Exactly, and that is what we want to do now.
- We want to place the garage entirely in the northeast, right at the boundary, with the main house designed as a townhouse and the granny flat to the left, so there is also a longer, wide courtyard.

- The kitchen does not need to be at the front facing the street.

- The choice of staircase does not matter.

- The sauna does not need to be inside the house; if at all, it should be in an extension near the garage, along with a small toilet.

What should remain is that the front door is centrally located at the front of the house and the granny flat is to the left of the single-family home, slightly set back by 1–2 meters (3–6 feet). Both the single-family house and the granny flat have a hipped roof, and the garage has a flat roof. For example, these two layouts.

Two architectural floor plans of a plot: house 103.31 m2, granny flat 68.57 m2, garage, plot 923.83 m2.

That won’t work. With boundary construction, living spaces are not permitted.

It’s one or the other. If the front door is centered on the main house, but the main house itself is not centered within the whole layout, it will look off.

Imagine what you’re planning as a face: both ears on the same side. The nose in the middle doesn’t save the symmetry.

Place the main house in the center. Give both side structures the same roof style. Set both outbuildings apart from the main building (or at least the garage far enough so that the center of the main house aligns with the overall center, taking into account the outer edges of the group).

That way, the entire ensemble visually looks balanced again — which it actually did in the design from kbt09.

Is the accessory apartment considered essentially a second house on the same property?

And again, one car in the garage plus parking spaces for two more cars?
