Hello,

I have been reading along for some time now and finally dare to share a floor plan here.
First, here is the list of questions:

Zoning Plan / Restrictions

Site plan with blue building structures, green areas and trees


Plot size: 576 sqm (6,200 sq ft)
Slope: Yes, slight. According to the site plan, the top "right" corner is at 295.4 meters (970 feet), lower at 293.88 meters (964 feet), left side goes from 295.17 meters (968 feet) to 293.43 meters (963 feet)
Floor area ratio: 0.3
Building envelope, building line and boundary: Applies to house number 16

Site plan of a building plot with parcels, building areas and street details.


Surrounding buildings
Number of parking spaces: 2
Number of stories: 2 full floors required, plus optional recessed floor (setback floor)
Roof type: Flat roof, max. 5° pitch
Maximum height/limits: Max. 10 m (33 ft) high
Additional requirements: Equipment (heat pump) must be integrated, not external. Maximum of 2 residential units. Specific exterior colors required, rainwater should infiltrate (soil report says this is unlikely). Roofs must be greened. No oil or gas heating allowed.

Client requirements
Style, roof type, building type: Actually, none specified.
Basement, floors: No basement, 2 floors.
Number of occupants, ages: 4 people — 2 adults, 2 children
Ground floor space needs: Daily life (living, kitchen, dining, technical room, guest room)
Upper floor: Family (2 children's rooms, master bedroom, separate bathrooms), home office
Office: Home office, second workspace for occasional use such as a work window sill for example in the bedroom
Guests per year: Currently few.
Open or closed architecture, conservative or modern style: Either is fine.
Open kitchen, kitchen island: We are still considering. Initial wish was separate pantry like in the floor plan. An island would be nice if space allows.
Number of dining seats: Normally 4, rarely up to 8.
Fireplace: None.
Music/stereo wall: Multi-room audio with central unit in technical room.
Balcony, roof terrace: Neither.
Garage, carport: 1 garage
Other wishes: Central vacuum system, laundry chute, smart home (KNX) (I am mostly doing this myself, yes, I am a certified electrician, can program, but will also get additional help)

House design
Who designed the plan:
- Planner from a construction company: Correct, with some input from us. Based on an existing plan.
Price estimate by architect/planner: approx. 485,000 € (euros) for the house, approx. 210,000 € for the plot including basic services (survey, soil report, etc.)
Personal price limit for the house including features: approx. 800,000–850,000 € (including land)
Preferred heating technology: Heat pump

If you had to give up, which details/extra features could you skip:
- Could skip:
- Cannot skip:

Why is the design like it is now? For example:
Standard design by the planner? Yes, with minor wishes from us (wall between study and child’s room 2, T-walls in bathrooms, porch roof, conservatory, pantry)
What do you find especially good or bad about it? So far it seems to fit; apart from possibly the pantry/dining room, we don’t see major issues yet. But that’s why I’m here now.

Floor plan of a house with rooms, furniture, outdoor area and dimension lines.

Floor plan of a single-family house: parent’s/children’s rooms, study, hallway, bathroom, garage.

Floor plan: green flat roof, conservatory above, garage on the left, VELUX windows in the center, dimension 10.96 m (36 ft).


Edit: The furniture shown in the floor plans can be safely ignored. Planners seem to like adding these.

Best regards
Ganneff

A sliding door is NOT a room door. It is not soundproof and lets all noise through.

All noise? I agree that it’s different from a regular room door, but it must block at least some sound. At least a quick web search suggests that sliding doors can be equipped with soundproofing.

That said, I also wonder—how much sound do regular room doors let through? They can’t be completely airtight either, due to controlled ventilation systems and supply/exhaust air requirements, right?

Exactly, that’s what this is all about; brainstorming and inspiration.
No one, including myself, is trying to preach to you here, but it shows you different lifestyles, each of which works, and that’s what makes it exciting.

I think that is a huge gift! Building a house is such an incredibly complex topic, where many far-reaching decisions have to be made within a relatively short time. Whether it’s space planning, window areas, heating technology, choice of provider (including wall construction), heat protection, and a thousand other things.

In the end, everyone has to build their own house and feel comfortable in it. At the same time, knowledge can be shared and costly mistakes avoided. Speaking of which...

Any? I agree that it’s different from a normal interior door, but it will provide some barrier. And at least a web search suggests that sliding doors can be fitted with sound insulation.

Though I wonder—how much do normal interior doors let through? They can’t be completely airtight anyway, because of controlled residential ventilation and supply/exhaust air systems, right?

I was also surprised about the doors (sliding door?) to the children’s rooms on the upper floor.

Even though I think it’s great to involve children in the planning of their rooms, I would consider that the children will grow up and then want normal doors installed.

As soon as children become teenagers, they will hate the sliding doors. Sliding doors offer significantly less privacy than normal doors. That will be a predictable problem.

It is a sliding door. The other person would prefer a swinging door, which we will probably craft ourselves.

If he actually regrets it in one, two, or three years—such a door doesn’t seem very expensive, judging by some websites. Then he can earn the money with a part-time job and replace it.
But—I really don’t think this will happen in the coming years.

I was already informed that I won’t receive any input until week 28.

Well, actually, I did get an update today. New drawings are attached. There are still two minor errors, but overall we’re quite happy right now.

On the ground floor, there is a slightly wider sliding door—now a two-panel one. We are still considering this, but regardless of whether it slides or not, it should be moved further to the right. I don’t know why it was moved to the left. It should *at least* line up directly below the wall partition with about 10 to 15 cm (4 to 6 inches) of wall width. This is still possible with the wider door.

The utility room has been rearranged and now has a window—although this reduces some wall space in the plan, and I still need to check with the utility providers if they have any objections (some seem to), I would like to keep it there. There is now a step drawn in front of the exterior door because there is a 35 cm (14 inch) height difference to the finished floor level. I’m not sure yet if this will bother me or not, but that’s a detail for the later construction phase; for now, it can stay as drawn.

The guest room now only has a standard window.
But the biggest change is in the upper right corner with the bay window. It features a large 2.50 x 1.50 m (8.2 x 4.9 ft) fixed window, which is why we planned it with an external venetian blind.

Upstairs, the bathroom redesign has been adopted, and none of the windows are floor-to-ceiling anymore. Instead, the children’s rooms have wider windows. The office is now centered as requested. This breaks the symmetry of the facade with the lift-slide door below, but that doesn’t bother us.
In the master bathroom, we still want to add a window above the bathtub, which was forgotten.

I think, apart from the two small corrections mentioned, this can be approved on our end, so that the following departments can start their work.
Comparing these drawings with the initial plans, they have really developed a lot—thanks again to everyone for their input!

When we get into the finer details, I will definitely be back, and hopefully (if everything goes according to plan, by mid to late next year) there will also be photos of the finished house. (For now, I’m really looking forward to finalizing the electrical planning.)

There are advantages to setting the sliding door in the living room slightly forward from the plane of the living room wall, in case you want to close off the living room there at some point.
In the study, I would probably plan just a single window and align it with the bottom edge of the other windows.
Is the washbasin placement under the window intentional?
In the utility room, I would allocate space for a cabinet and a workspace for laundry, and prefer to keep it free of technical equipment.

What does the utility provider care about the window?
