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

Then forget about the knee wall. There are also beautiful houses with a small knee wall, where the steep roof pitch and dormers do the work, like here.

Yes, that was the idea. To minimize the sloping ceilings in the rooms (especially on the south side) as much as possible.

And what about a house with a third gable?

Our builder said a third gable is much more expensive than a dormer like this. So we designed it this way with the architect.

The south dormers are huge. How much do they cost?

Huge in the sense of ugly or monstrously expensive?

Hmm, yes, that’s true. Unfortunately, I can’t quite get used to the 1 meter (3 feet 3 inches) height. It’s kind of neither one thing nor the other—especially when I can choose freely.

Here, the usability of the attic space is important. The original poster is even building stairs up there, so it should be worthwhile. So far, the attic looks like this to me with a 1 meter (3 feet 3 inches) knee wall, just to give an impression:


Attic room with wooden door frame, gray walls, carpet, and view of staircase landing.


Here, I created a recess at 70 centimeters (28 inches). The door is 2.10 meters (6 feet 11 inches) tall. So, really full standing height is only available along a strip about 1 meter (3 feet 3 inches) wide under the ridge. If the roof were 30 centimeters (12 inches) higher, I think it would already make things much more comfortable.

ops:
I thought expensive. But if it's a bargain according to the building planner ...

The usable space at the roof peak is important here too. The original poster is even building a staircase up there, so it should be worthwhile. So far, with a knee wall height of 1 m (3 ft 3 in), this is what the peak looks like for me, just to give an impression:



Here, I dug down 70 cm (28 inches). The door is 2.10 m (6 ft 11 in) tall. So real standing height exists only on a strip about 1 m (3 ft 3 in) wide under the ridge. If the roof were 30 cm (12 inches) higher, the situation would be much more comfortable, I think.

Hmm, but a higher knee wall can’t be combined with dormers, right? Yeah, the space upstairs is really limited. That’s a 45° pitch, isn’t it? What ceiling heights are you working with? Would a cross-section drawing be helpful for you? The usable space in the dormer area (up to 70 cm / 28 inches) should become wider there, shouldn’t it?

Cross-section of a two-story house with roof truss, dimensions, and staircase.

Just ask the architect! He still has to change the staircase anyway.

I will do that as well

My wife also has a say here. We haven’t yet decided what changes we want to make to the stairs, or whether we will change the stairs at all, or if we will make the wall to the bathroom upstairs curved or more slanted. We will definitely discuss these ideas with the architect again. But I don’t just have to convince myself here, I also have to convince my wife... and most people know that “more practical” as an argument doesn’t always work out ^^

About the section drawing: the knee wall is currently at 75cm (30 inches). If we raise it to 1m (39 inches), as we would like, there is a small problem with the dormer windows.

- The dormer windows would also be raised
- in order for the window sill to have a normal length, the dormer windows would need to sit on the roof. So the window sill would be at about 1.35m (53 inches), which is quite high already.

Setting the windows on the first beam would be possible, but then the window sills would have to extend further out beyond the roof. What do you think? I hope it makes sense what I’m trying to say with my amateur knowledge. ^^
