ᐅ Floor plan design for a single-family house of approximately 125 square meters, with two full stories

Created on: 27 Jul 2018 22:33

We plan to build a single-family house with about 125sqm (1,345 sqft). We would like to include a small home office on the upper floor.

We prefer not to have the staircase directly next to the front door to avoid having to walk through the “dirty zone” all the time. However, an L-shaped staircase next to the front door might save space. This would allow for a larger utility room (the front door would be moved slightly).

The kitchen cabinet layout is not finalized yet. A place for a fireplace is also still missing (the challenge is integrating the chimney on the upper floor).

Development Plan / Restrictions
Plot size 1000sqm (10,760 sqft)
Slope approx. 1 – 1.5m (3 – 5 ft) decline from north to south over 50m (164 ft).
Site and floor area ratio unknown, as §34 applies
Building envelope, boundary lines Building envelope 5m (16 ft) from the street on the north side, approx. 20 x 20m (66 x 66 ft), on the west side 15m (49 ft) distance to the neighbor’s building envelope, meaning the minimum distance to the west neighbor is 15m (49 ft), see site plan.
Edge development -
Number of parking spaces -
Number of floors 1–2
Roof type / Style / Orientation no restrictions
Maximum heights / limits -

Owners’ Requirements

House Design
Designed by: > Do-it-Yourself
What do you particularly like? Why? What do you dislike? Why? The north and west elevations look a bit odd; maybe an additional window should be added there.
Personal budget for the house, including fittings: approx. 250,000€
Preferred heating system: Gas or air-to-water heat pump

If you had to give up anything, which details/extra features
- could you live without:
- could you not do without:

Why is the design like it is now? For example:
We used various floor plans from prefabricated house providers/contractors found online as templates.

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

The following questions:

1. Is the floor plan feasible and practical to use?
2. Would an L-shaped staircase be preferable to save space?
3. Do load-bearing walls on the upper and ground floors have to be aligned?
4. Where is the best place to position the carport on the plot, northeast or northwest?
5. How can the chimney for the upstairs fireplace be integrated without taking up too much space?

Floor plan:

Floor plan of an apartment with living/dining, kitchen, hallway, utility room, bathroom, and U-shaped staircase.

I’m afraid the utility room is still quite small. Also, I would probably swap the children's room and the bedroom upstairs. You likely spend less time in the bedroom than the child, who also has a desk in their room.

Yes, we have already considered swapping the bedroom and the children’s room. The children’s room would then have a north/east orientation. Unfortunately, due to the structural constraints, the wall between the bedroom and children’s room cannot be moved, so swapping is probably the better option.

@ypg
The comments regarding the size of the utility room are certainly valid. However, a utility room larger than 10sqm (107.6 sq ft) will hardly be feasible with the given floor plan. Also, stacking the WC and bathroom is challenging. Do you have any ideas on how to optimize the floor plan?

Are there any other opinions on the orientation of the house and carport?

Bathrooms or toilets stacked vertically for drainage
Combine guest room and office, and include a large closet, desk, and sofa bed there
Allocate 5 square meters (54 square feet) for a freezer
Allocate 3 square meters (32 square feet) for washing machine and dryer
Allocate 1 square meter (11 square feet) for cleaning supplies
Allocate 1 square meter (11 square feet) for tools
Plan for 2 linear meters (6.5 linear feet) of closet space for seasonal clothing
Allocate 60 cm (24 inches) of closet space per person for coat storage
Walk-in closet should accommodate at least 3 linear meters (10 linear feet) of closet space, with enough room to step back in front of it

The recommendations regarding the size of the utility room are probably correct. However, a utility room larger than 10 square meters (108 square feet) will be difficult to fit on the available floor area. Also, stacking WC and bathroom is challenging.

I never said you need a utility room larger than 10 square meters (108 square feet).

I described what would be necessary to live without compromises. If that is not feasible for you, then please consult a professional. Stacking bathrooms vertically is almost always possible.

If you don’t want to spend much money or cannot, then this is a rule you should implement. Almost every standard house type includes this rule.

Who says that and why?
In a typical hip-roof suburban house, I would rather expect drywall partitions on the upper floor (or, if needed, aerated concrete at this location), so I don’t see any problem.

Here is my idea with the same external dimensions, assuming the structural aspects can be managed. (I also left out the windows.)

Floor plan of a living/dining area with dining table, kitchen island, and sofa; hallway, utility room, WC, stairs.

The kitchen and dining area could have direct access to the terrace.
There is space for a wardrobe and the utility room has grown (not sure if this is enough).
The WC still has room for towels and cleaning supplies.

Floor plan of an apartment: hallway, bathroom, children’s room, guest/office, spiral staircase.

Bathroom above the WC. Guest room and office combined. The child’s room is oriented south/west.

EDIT: Oops, the guest bed moved a bit.

How about using the Flair 130 as a template ...

hmm, I don’t find the orientation on the ground floor there very appealing. I don’t understand why “everyone” always wants their living room in the southwest. I think northwest is a much better location; plus, then the kitchen is in the southeast instead of the northeast, so you still have sun in the kitchen around midday and in the afternoon (since you prepare food several times a day, while I usually sit on my sofa in the evening).
