Floor plan MGH 200QM - Evaluation ideas

Hello,

I have been reading here for a while, now we have purchased a plot of land ourselves and are planning a house on it.

Questionnaire:
Development plan/restrictions

Size of the plot = 525 m2
Slope - 1M height difference downwards to the south
Site coverage index = 0.4
Floor area ratio unknown
Building window, building line and boundary = Plot 18.2 x 29, building window 12.2 * 20. Similar plots to the left and right (new development area)
Edge development = No
Number of parking spaces = 2
Number of floors = 2
Roof shape - SD 25-45 degrees
Style = Modern, timeless
Orientation = unknown
Maximum heights/limits = Eaves height 4.5, ridge height 8.5. Since eaves height applies from the reference height, but the reference height is 1.5 M above the ground, we can build two full floors.

Client requirements

Style, roof shape, building type = Modern, straight and practical. Gable roof east-west (with photovoltaics).
Basement, floors = No basement, 2 floors
Number of persons, age = 2 x adults (around 50), 2 x teenagers
Space requirements on ground and upper floor
Office: family use or home office? = 4 days HO, own room necessary.
Overnight guests per year = Several, family lives far away, they like to come for 1-3 weeks at a stretch.
Open or closed architecture = open
Conservative or modern construction = modern
Open kitchen, cooking island = yes!
Number of dining seats = about 6
Fireplace = yes, small masonry heater
Music/stereo wall = no, also no TV on the ground floor
Balcony, roof terrace = yes
Garage, carport = yes
Utility garden, greenhouse = no, rather flowers and nature. Small but nice.

Further wishes/special features/daily routine, also reasons why this or that should or should not be

We like to cook, the kitchen should be a focal point. The inside and outside should also be "connected". Lots of light, no shutters.
The ground floor should be age-appropriate, not only for us but also so that maybe a grandparent could live with us instead of a child (we could then live upstairs that long). Better to have and not need than to need and not be feasible.
View to the south (field and forest) is important.
Upstairs in the "chill room" a kitchen must later also be able to be installed if a child/grandparent wants/needs to live there independently.
We want to build the house from solid wood, with whom exactly we don’t know yet.
Possibly cast floor on the ground floor, parquet or similar upstairs. Ground floor height 2.7 M (is that enough?), thickness of the ceiling (cross-laminated timber, no beams) I have currently assumed 40 CM. Ceiling height upstairs can be less as rooms are not so big there.
Garage rather not intended for the car, instead double carport.

House design

Who is responsible for the planning:
-Do-it-yourself

What do you particularly like? Why? Ground floor with easy access to the terrace and garden and private view to the south, covered terrace (can be used even in rain). Kitchen close to the west terrace with its own access.

What do you not like? Why? Upper floor is a bit too big for us, but that results from the ground floor (darn). I also think there is too little space for the stairs.
Price estimate according to architect/planner: We are not that far yet, I currently calculate with 2500 - 3000 euros/sqm.
Personal price limit for the house, incl. equipment: < 600K (land is already paid, terrace, carport I can do myself)
Preferred heating technology: Air heat pump with underfloor heating

If you have to do without, which details/extensions
-can you do without: living area, cooking island
-can you not do without: barrier-free ground floor

Why is the design the way it is now?

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

How can we reduce the house size or make it cheaper without losing function (barrier-free) on the ground floor, we are concerned about costs (maybe unjustified). Do you see any other cost drivers? (Besides masonry heater and too much glass). General feedback also welcome.
(I am not a native speaker, please excuse spelling errors)

Thank you all!

Hello,

then I'll start. The "real floor plan pros" will see even more. :p

- I find the budget very questionable. In BW with such a cast floor, photovoltaics, solid wood construction, wooden facade and so on... Carport/terrace included in the budget? Being able to do it yourself still means paying for the materials... the sqm price is probably over 3000/sqm.

- Construction style modern, timeless... well, matter of taste and I'm bad at graphics but it doesn't look that modern to me... but I might be wrong.

- You can also raise roller shutters or blinds... you don't always have to have them down, I would consider that depending on the location regarding summer shading.

The floor plan didn't really click with me.

- The idea of the chill room upstairs for later conversion is nice, just make sure the wiring works (keyword drainage etc.)
- Is the bed supposed to stand like that on the ground floor? I find the head next to the entrance peak uncomfortable. What are the measurements here? En suite bathroom is certainly nice, but keep in mind that everything is arranged along the living room wall. Keyword noise.
- Where do you hang your coats?
- You are building without a basement, did I miss something or do you want to fit the less than 7 sqm of technology and laundry and storage somewhere else?
- The small room by the kitchen? Pantry? What are the measurements and what is supposed to go in there?

That’s the first impression...

Thank you, I have the ground floor here again with the missing dimensions. (Can't edit the original somehow). The small room is indeed a pantry. Modern refers more to the layout (lots of glass, large living/cooking dining area), but it is certainly also a matter of taste or how one wants to define it. On the west side we still need something against the evening sun, we are still considering that. Coats in the hallway on the right lower wall. The garage is also supposed to serve as storage, but yes, it will be tight, that's true.

... and here we already have the first one who likes it - contemporary and timeless :)

Regarding the floor plan, I am not sure if the furniture has the correct dimensions. There is certainly little leeway in case something doesn't fit somewhere. On the ground floor, the entrance area, staircase, and utility room are too small. A wardrobe is completely missing. You could try moving the wall of the hallway downwards on the plan (towards the pantry). Then the room entrance would be through the hallway. On this occasion, I would also try to combine the guest WC and the ground floor bathroom. Use the gained space for the staircase, wardrobe, and a larger utility room. It's still a bit of a puzzle, but there is potential lurking there. If it helps, you can compress the kitchen area a bit more to the left on the plan and omit the stools in favor of a larger island.

Upstairs, I would omit the door between the staircase and chill room, and swap the study with the bathroom. If the guest room can be moved downwards on the plan, you would get rid of the unused space in the bottom right room. The gained space could be used for closet space or space for laundry equipment.

Eaves height 4.5, ridge height 8.5. Since eaves height applies from BZH, but BZH is 1.5 m above the ground, we can build two full proper storeys.

Such differences usually do not come from nowhere. I read this with caution as an indication of a steep slope and/or significantly changed terrain heights after development. Tell me (not as a link!) where we can read the original development plan.

The upper floor is a bit too large for us, but it results from the ground floor (Düh)

Düh?

My spontaneous initial surprise concerns the question of why someone would put up with a side entrance or two and a half meters garage-house distance, forcing the footprint unnecessarily into a long format.

Thank you for the valuable comment (Hangman),

I think the dining table is shown too large (3m long), it can comfortably seat 8 people (Trimble warehouse says hello, thanks for the hint). There should actually be enough space overall (in our current house we have 8 x 4M for living and dining, here it would even be a little more).
I like the idea with the entrance area, stairs, and utility room, I will try something in the next few days, the disadvantage would be that the bedroom access is through the shared hallway, so if my kids come home late after a party night, you would hear them more, which was actually the reason to have the access inside the apartment. The advantage would be more utility room :).

Upper floor: I need to analyze the swap between the AZ and bathroom.
The door between the stairs and chill room can be removed (or moved a few meters forward so that the bathroom and guest room are behind it), the idea is that the upstairs residents have more privacy when the door is closed. Possibly I will install a double door there that can open across the entire width of the hallway, then there is flexibility. (Just leaving it open would be like having no door), it could possibly be done later as well.
Making the large room at the bottom right smaller will be difficult, there will be trouble here. :)
