Hello everyone, we are looking for a floor plan for a semi-detached house!

Most semi-detached houses are long and narrow, but our building area does not allow that.

We want to live in one half of the semi-detached house
And rent out the other half. We prefer not to be alone.

Development plan / restrictions
There is only one supplementary ordinance. Construction according to Paragraph 34.

Size of the plot: 815 sqm (8770 sq ft)

Open construction method according to Paragraph 34.

Slope: yes, over 16 m (52 ft) there is a 1.5 - 2 m (5 - 6.5 ft) gradient.
Floor area ratio: 0.4
Floor space index: not specified anywhere.

Building area, building line, and boundary
8.5 m x 16 m (28 ft x 52 ft) according to surveyor.

Edge development: no
Number of parking spaces: flexible
Number of floors: 1.5 - 2 (neighbors)
Roof shape: gable roof > 35 degrees
Architectural style: classic mixed with modern
Orientation: see drawing
Maximum heights / limits: unknown
Other requirements

Homeowners’ requirements:
Style, roof shape, building type

Classic-modern, gable roof, semi-detached house

Basement: yes, floors 1.5 - 2

Number of people: 3 adults, 2 children, 1 toddler
Room requirements on ground floor: kitchen, living room, dining room, shower bathroom
Upper floor: master bedroom, two children’s rooms, bathroom.
Office: nice to have, but not mandatory – home office!
Guests sleeping overnight per year: none
Open or closed architecture: open
Conservative or modern construction: flexible
Open kitchen, cooking island: would be great
Number of dining seats: 8
Fireplace: no
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: yes, 2 spaces
Utility garden, greenhouse
Other: 1 garden north, 2 gardens south

Requests / special features / daily routine, also reasons why this or that should or should not be included: we are open to everything, we want to build something that makes sense! It does not need to be large! We currently live in 102 sqm (1100 sq ft) plus basement and that is sufficient.

House design
Who is responsible for the planning:
We do not have one yet! The plan below would be acceptable for us, but it needs to be made quite square. Has anyone worked on a similar project?

- Architect: We want an architect to help us but do not want to hire one unprepared.

- DIY: That’s why we want to gather as much input as possible.

What do you particularly like? To make full use of the building area, if possible. Why? So that there is not a 100-130 sqm (1075-1400 sq ft) house on an 815 sqm (8770 sq ft) plot, and we would like to have neighbors!
What do you not like? The 8.5 m (28 ft) width of the building area. Why? 10 m (33 ft) would be optimal for a nice semi-detached house.
Price estimate according to architect/planner:
700,000 euros without land!

Personal price limit for the house including equipment: 400,000 euros per semi-detached half
Preferred heating system: solar thermal combined with gas

If you had to compromise on details/additions:
- What could you live without: office
- What can you not live without: large kitchen, all activity centers around the kitchen and dining room, we hardly ever use the living room!

Why is the current design the way it is?
We actually do not have one.

Standard design from planner? Yes

Which requests were implemented by the architect?
A mixture of many examples from different prefabricated house catalogs.

What do you think makes it particularly good or bad?
No compromise on the kitchen, as it is our central living space.

Bad: possibly planning a semi-detached house, maybe better a house with a granny flat?

What is the most important/basic question about the floor plan summarized in 130 characters?

How can we combine family life with spatial design in one half of a semi-detached house?

Hello everyone, okay, apparently there is still a lot of work to do! Thanks for the valuable tips.

@ypg
1. Regarding the master bathroom, we don’t mind where the entrance is. A kids’ bathroom is also not absolutely necessary. We would just find it practical. We assume that since the bathroom is in the basement and extends all the way up to the attic, ventilation will be necessary anyway! That’s why we chose this.

2. The idea of building an enclosure in the living room because of the window is a good point. We will have to reconsider that.

3. Initially, we wanted a monolithic construction method, but now we find brick exterior very appealing and like the idea of a double-layer masonry wall.

4. Living room facing south so that we don’t have a long walk to the north terrace; possibly a south-facing balcony is planned, but we are not entirely sure yet... Regarding wasting living space, I don’t fully understand—our idea was rather to have kitchen, dining room, and living room arranged in a row, which we think would be ideal because it could then create a home office/guest area.

Thanks

@11ant:
Good tip, we will reconsider that. We had assumed that a 1.5-story house with a few windows on the roof would be much cheaper.

We didn’t want two full stories because it doesn’t look very good aesthetically and would require two concrete ceilings. That was our idea.

Thanks, that helps us, now the thinking process begins again...

Best regards

I can’t follow that: you don’t actually need fewer windows just because they are vertical or sloped, do you?

And here I still don’t understand: a) the proportions of this building don’t work anyway; b) what does that have to do with the ceiling or floor slab construction?

3. At first, we wanted a monolithic construction method, but now we find clinker brick very appealing and love the idea of a two-layer masonry wall.

If not clinker brick, what else is the current facade design supposed to represent?

Now the doubts start again.....

About what exactly? — I already see no potential whatsoever to increase the level of lack of concept any further.

What does the architect do professionally? — She apparently doesn’t notice the most obvious mistakes and doesn’t seem to provide any meaningful advice either…

Thank you, then we really have to ask ourselves whether it is the right one for us who have no plans.

I also don’t see what you could build with this "architect"—except "on sand." Laypeople without a plan need professionals who know what they are doing. At most, either the builder OR the architect should not know the direction to take.

Floor plan of a house with basement, staircase, hallway, room 1, and kitchen.

Floor plan of an apartment: living room, kitchen, hallway, cloakroom, bathroom, stairs, office.

Top-down view of a small house with several rooms on green land.

Floor plan of a residential layout: hallway, staircase, bathroom, kitchen, 2 bedrooms (K1, K2), and study.

White, two-story 3D house with dark roof, two skylights, and glass sliding door to the terrace.


So, here is my proposal for the 8.5 x 12-meter (28 x 39-foot) house with a 1.50-meter (5-foot) knee wall, with north at the top.
I have included 5 roof windows. You really need to calculate if that is economical.
I’m not sure if the fill and so on are cost-effective or compliant; the client will need to check that.
This is just an idea: a retreat area in the north overlooking the garden, a west-facing terrace for the kitchen/dining area. Adequate wardrobe space, open staircase.
One small change I’d suggest: swap the toilet and bathtub in the children's bathroom, so it can also be used as a shower room :P
