Hello everyone,

we are currently in contact with a developer because we would like to sell our current house and build a new one. Our current house is an extension, has 140 m² (1506 sq ft), and is almost 40 years old.

In the new development area, mainly semi-detached houses are being built, which we find very suitable for our small family.

Here is the completed questionnaire:

Development Plan / Restrictions
Plot size: 330 m² (11 x 33 meters) (3552 sq ft; 36 x 108 feet)
Slope: no
Floor area ratio (FAR): 0.25
Plot ratio: -
Building setback, building line, and boundary line: 3 meters (10 feet) from the plot boundary
Edge building: allowed up to 3 meters (10 feet) height
Number of parking spaces: 2
Number of floors: 1 + recessed (setback) floor
Roof type: gable roof
Architectural style: modern, timeless
Orientation: see floor plan
Maximum heights / limits: top edge of structures max. 7 meters (23 feet)

Homeowner Requirements
Style, roof shape, building type: semi-detached house with gable roof
Basement, floors: no basement, 2 floors
Number of people, ages: 2 adults (37 & 36), 1 toddler (will remain one child)
Space requirement on ground floor and upper floor: total 115 m² (1238 sq ft)
Office: family use or home office? Both use home office occasionally, possibly a 2nd workspace?
Guests per year: 0
Open or closed layout: open

Open kitchen, kitchen island: open kitchen with peninsula
Number of dining seats: 6-8
Fireplace: -
Music / stereo wall: -
Balcony, roof terrace: -
Garage, carport: -
Utility garden, greenhouse: not planned at the moment

The furniture shown on our own floor plan is currently owned by us and we intend to keep it for now.

House Design
Who designed the plan:
- Planner from a construction company
- Do-it-yourself
What do you especially like? Why? The large living/dining area with an open kitchen, many windows on the ground floor for brightness
What do you dislike? Why? On the original floor plan: the open staircase, children’s room too small, arrangement of parking spaces, lack of storage, utility room too small
On our self-designed floor plan: problematic arrangement of sofa/TV and dining table
Price estimate according to architect/planner: €389,000 (special requests like additional windows and other changes not yet included)
Personal price limit for house including fittings: €450,000
Preferred heating technology: heat pump with preparation for photovoltaic system

If you have to give up something, which details or expansions
- you can give up: -
- you cannot give up: -

Why is the design like it is now?
Our own floor plan has more storage space, and we prefer the arrangement and size of rooms on the upper floor.

As mentioned before, we are still not completely happy with the ground floor or how to best arrange our furniture. The staircase takes up less space on our plan now, but it is still unclear whether we are allowed to change the staircase shape. We definitely want a staircase located in the hallway and separated from the living/dining area, because currently we have an open staircase and are not happy with the noise. Maybe you have ideas on how to integrate the staircase differently.

According to the developer, we can still make changes to the floor plan, but the extent of this will be clarified tomorrow (appointment with the developer). Originally, for example, the utility room was planned on the west side, which is not ideal.

Storage space is also a concern. Although the utility room is now larger, we would still like to have a small storage room under the stairs as shown. Maybe a bit of the children’s room on the upper floor could be allocated for another storage space? The room is actually already quite large...

We have not yet considered the possibility of a 2nd workspace if my husband and I both work from home at the same time.

Due to the low floor area ratio, outdoor space is also challenging. We do not like the arrangement of parking spaces one behind the other and would rather place both in front of the house. However, we would then have to give up the carport, which is not very important to us since it would be an optional feature.

Do you have ideas on how these points could be implemented or how the floor plan could be changed to better suit our needs? I know that space is limited with 115 m² (1238 sq ft).

Many thanks!

Are the external dimensions already the maximum? The floor area ratio would still allow for a bit more length, wouldn't it?

The issue is the outdoor areas with the terrace, parking spaces, and the path to the house. Our builder has actually already maximized this, including a 50% exceedance to 0.375. Therefore, the external dimensions cannot be changed anymore.

Tell me, how did the planner envision the bathroom? The washbasin is actually below the 2-meter (6.6-foot) height line!

On the floor plan, the line by the bedroom shows 220 cm (87 inches), and in the bathroom 200 cm (79 inches)... strange.

Well, good question, that’s really inconvenient with a double washbasin...
We’ll have to bring it up at our appointment tomorrow; only a single washbasin really makes sense here...

I revisited the upper floor layout and find this one makes the most sense.

Floor plan of an apartment: Bathroom 9.6, Bedroom 12.8, Storage 2.1, Child’s room 15, Hobby/Utility room 11.4, Room 5 8.8 m²


The rooms are located and lit almost perfectly according to their intended use. The office/hobby room only has a roof window, but that should be sufficient for its purpose. The child’s room gets the brightest and largest corner. The office also serves as a utility room, and the bathroom still needs to be checked regarding the 2-meter (6 ft 7 in) height clearance (washbasin area).
It looks like ironing might happen in the bedroom as well? Either way, the space could be reduced if additional storage is needed.
The planner’s staircase also makes the most sense based on the house’s overall dimensions.
On the ground floor, one could proceed like this:

Floor plan of a house: Hallway, staircase, kitchen/dining, living room, utility room, storage, WC, cloakroom.


Compared to this layout, where the kitchen is really unsatisfactory, although I prefer the closet in the hallway:
