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

I would ask the general contractor what 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 walls remain the same, simple shape, straightforward roof, no transitions or corners)

I will definitely do that. Thanks for summarizing. The last option should probably be the most affordable.

I’m not sure it would be cheaper since it would be larger. It probably wouldn’t be much more expensive either. In 2016, we had two quotes for a bay window in the dining area and a balcony upstairs; both company consultants said it would cost about the same as enlarging the entire house by the size of the bay window.

In any case, those few square meters on each floor would definitely be beneficial.

- All rooms have been rearranged except for the bathroom and utility room
- Staircase rotated – it no longer extends into the utility room but into the office

This is how I imagine it and could live with it

- The living room could be separated if needed
- The kitchen is the first room, so the living room is no longer in a through-way

Upper floor

Warm or cold (or disaster)?

Disaster!

Ok, I should give up ^^ There’s a reason why I didn’t become an architect.

As far as I understand, a wall with a higher knee wall must bear more load because the leverage from the roof increases.

That is basically correct – but it does not mean that the house will automatically be more expensive because of a higher knee wall. As mentioned: overall ... more knee wall, less roof pitch / no bay window, but spread over the building depth – these elements are interconnected and tend to be "rebalanced" rather than making the total cost higher or lower.

We haven’t considered the Neo yet. With dimensions of 11.1m x 9.3m (36.4 ft x 30.5 ft), we would roughly end up with the same base floor area. Knee wall at 1.30m (4 ft 3 in), ceiling heights: ground floor 2.60m (8 ft 6 in), upper floor 2.50m (8 ft 2 in). For K3, we could reconsider a shed roof or something similar. For cost reasons, initially only double casement windows. Stairs again offset above each other (no landing) – please put on your glasses!
Upstairs facing south as usual:


Grundriss: Büro, Diele, Dusche, HAR; runder Esstisch mit Stühlen, Treppen, Türen.


Grundriss eines Stockwerks mit Flur, Treppe, Bad, SZ, K1-K3, A, Dusche.


Grundriss eines Gebäudes mit violetten Außenwänden, mit einer zentralen Treppe, Innenwänden und Türen.

I haven’t given the chimney any thought yet. It could be tried out if it suits the design at all. It would probably be placed on the gable side.
