Hello House Building Forum

I am new here, and we are currently planning our house with an architect. There are currently 4 of us, but we plan to have a 5th. Therefore, the house will include 3 children's bedrooms.

Here is the questionnaire:

Development Plan / Restrictions
Plot size: 1250 sqm (13455 sq ft) on 25m x 50m (82 ft x 164 ft)
Slope: no
Site coverage ratio: 0.4
Floor area ratio: not sure at the moment
Edge development: allowed but I want to avoid it
Number of parking spaces: double carport + 2 cars in front

Roof style: gable roof
Architectural style: classic single-family home
Orientation: see drawing

Owners’ Requirements
Open floor plan on the ground floor, 4 bedrooms on the upper floor, attic with enough space for storage and a hobby area

House Design
Who created the design:
- Architect

What do you like most? Why?
Ground floor: open kitchen and living room. Office accessible from the living room. Direct access to the terrace.
Upper floor: accommodate 3 children’s bedrooms, bedroom with walk-in closet area. The large dormer. The stairs to the attic, where the hobby room will be located.

What do you dislike? Why?
Basically only the staircase to the upper floor. I am a bit bothered by having to walk “around the corner” when coming up. I am looking for ideas to improve this. Or is this concern unfounded?

Cost estimate according to architect/planner:
Not determined yet.

Personal budget limit for the house, including fittings:
350,000 Euro

Preferred heating system:
Gas boiler, solar thermal, and underfloor heating

If you have to give up something, which details or extensions can you do without:
We have already eliminated everything we could possibly do without.

Why is the design the way it is? For example:
We went to the architect with our preferred design. He used our floor plan as a basis and created a floor plan that we like even better. Only the staircase layout is not yet 100% satisfactory for me.

What is the most important/basic question about the floor plan, summarized in 130 characters?
As mentioned, the staircase to the upper floor is my biggest concern. I hope to get some ideas on how to improve it and maybe some feedback on the rest.



Ground floor plan: kitchen/dining/living area, hallway, office, utility room, bathroom, fireplace in the living room.


Upper floor plan with master bedroom, three children’s rooms, bathroom, landing, and storage room.


South is “up” on the drawings



If more information is needed, I am happy to provide it.

Best regards

Exactly – and just to clarify, this isn’t about my pedantic use of terms, but about your observation that a higher knee wall doesn’t necessarily push your window sills upward.
I’m afraid I don’t quite follow anymore. That can’t be right, can it? If my knee wall is at 1.30 meters (4 ft 3 in), then my roof should start at the earliest at 1.30 meters (4 ft 3 in) as well. Or are you suggesting placing the window beyond the wall? That would mean I’d have to remove part of the wall.
Could you maybe draw a sketch? *blink, blink, bat eyes*

Just out of curiosity, can anyone estimate what it might cost to raise the knee wall from 75cm to about 130cm (I would have whole courses of bricks raised to avoid cutting)? I have no sense at all for this.

Neither do I (among other reasons, because “only fools shorten sums”): increases are rarely linear; usually, a compensation in the form of a reduced roof pitch is included as part of the overall measure. Don’t worry about “whole brick rows” — in a worst-case scenario, smaller formats are still available. For the target size of 130, however, five rows in the most common large format (125) are probably the most practical — although you could add a row of DF or NF bricks, resulting in about 131.3 / 133.3.

I’m afraid only your general contractor can give you an accurate answer. It varies a lot depending on the location, and most people don’t buy their house brick by brick, but rather the complete shell for a fixed price.

Ok, thanks for now. From what I understand, the wall with the higher knee wall has to withstand more because the leverage force from the roof increases.

My question was simply whether that would cost about 5,000 or 15,000 more. Just a rough estimate.

We are currently (once again) working on the floor plan. We started by optimizing our layout. I still need to redraw the other suggestions calmly. My wife doesn’t have to watch over me for that. But @Niloa was right. The kitchen didn’t work.

After playing around with our floor plan, this is what we came up with. The idea was to swap the office and the kitchen.



Floor plan of a house: living, dining, kitchen, hallway, utility room, entrance area, office, bathroom.


- swapped all rooms except the bathroom and utility room
- rotated the stairs – they no longer intrude into the utility room but now lead into the office

This is how I imagine it and could live with it.

- The living room could be separated if needed
- Kitchen is now the first room, so the living room is no longer just a passageway

Upper floor

Floor plan of an apartment with multiple rooms, bathroom, master bedroom and walk-in closet.



Cozy or cold (or a disaster)?

I would ask the general contractor which option is more cost-effective:
- lower knee wall with dormers
- higher knee wall without dormers
- larger floor area but no bay window, gable roof without dormers (the linear meters of exterior wall are the same, simple shape, simple roof, no transitions or corners)
