Hello,

we are a family of five planning to build a single-family house in Lower Saxony next year. The house might be divided in about 15 years so that my wife and I will live on the ground floor and the upper floor could either be sold or stay for the younger generation of the family.

The plot is a gap in the row of buildings, there is no zoning plan.
The plot size is 911 sqm (9,800 sq ft).
The exterior dimensions of the house are 12.5 x 10 m (41 x 33 ft).

Roof type: gable roof
No basement, ground floor and attic with knee wall of 1.5 m (5 ft)
Number of residents: my wife and I, three children aged 7, 10, and 13 years
Room requirements on ground floor and upper floor
Office: family use or home office?
Guest bedrooms per year
Open or closed floor plan
Conservative or modern architectural style
Open kitchen: no
Number of dining seats
Fireplace: not decided yet, probably no.

A conservatory is planned on the west side of the living-dining area, facing south and west.
Garage: planned as a prefabricated garage, carport: opposite the north side (next to the utility room side entrance).

House design
Planning by: Do-it-Yourself
Preferred heating system: gas condensing boiler

Please share your opinions.

... to put it simply:

You first need to plan a two-family house, which you then adapt for your use – not the other way around.

I believe that an apartment without a balcony will be difficult to sell.

Unfortunately, a site plan including access paths is missing once again.

Regarding the balcony, I agree with Curly. Also, a site plan is important because if you ever want to sell the upper floor as a separate apartment, you need to consider parking space and possibly a small garden area for the upper unit.

That said, I wonder if it wouldn't be better to plan so that a caregiver or similar could be accommodated upstairs.

Thank you for the comments and tips.

You are, of course, right about the bathroom; I have made the changes.

@Doc.Schnaggls:
-We have incorporated many suggestions that we now find good (or at least not bad), including the location of the stairs relative to the front door and the distance between the door and the chairs in the dining area. However, a sliding door between the kitchen and dining area is a very good idea, thanks.

-I did not understand the idea with the skylights above; could you please explain?

-I also find the door arrangement between the hallway, utility room, and kitchen a bit unusual. However, I don’t want to reduce the size of the utility room because then I would need to place a door on the wide wall of the utility room (opposite the secondary entrance). What do you think?

-The separation of the technical areas is, of course, planned, including the connections for a kitchen upstairs. I have attached my idea of how the separation in the entrance area might work.

@Climbee
My wife had the same thought at first, but the route is only 1m (3 feet) longer than what she has now, and this way we benefit from all rooms with water pipes being on one side.

@hbf12
I was also concerned about the space requirements in the utility room, but after a conversation with the heating and plumbing company and reading a few topics about it here in the forum, I believe it will be sufficient. How is the space for technical equipment in your home?

@kbt09
Thank you for your comment regarding the bathroom. I don’t yet have a site plan. I wanted to first gather opinions on the layout and space requirements.

@Nofret
You are right—as you say—it is planning a two-family house that functions as a single-family house at first. But we are not willing to go outside in the cold every time we want to move between the two floors.

@Curly
You are right, a balcony does make an apartment more valuable.

Then heat the stairwell separately – this way, it will not turn into a two-family house.

So, what will the upper floor look like after the separation?

And one more thing... how can you design a house with an entrance, etc., if you don't have a site plan?
