Hello everyone,

We recently made a spontaneous decision to build a single-family house after unexpectedly acquiring a plot of land. Meanwhile, price negotiations with several construction companies (turnkey) have been completed, and the contracts have been signed.

I would appreciate it if some experienced homeowners could take a look at our floor plan. We can still make minor changes. Special attention should be given to the roof windows. Are they too large or too small? Could the double casement window (which is also planned to be 94/140cm (37/55 inches)) in the bathroom or bedroom be omitted? Is there a rule of thumb for window area? What are the advantages of pivot and tilt-and-turn windows?

Furthermore, we need to consider the placement of recessed ceiling spotlights on the ground floor soon. Is there a good planning guide available online, perhaps including recommendations on the required wattage or lumen output per square meter? For example, the office is roughly 4x4 meters (13x13 feet). If I arrange ceiling spots in a near-square pattern, there would either be 9 or 16 fixtures – how should I approach this decision?

Thank you for any feedback.

Note: There are still some minor errors in the floor plan; the terrace is drawn incorrectly, and the kitchen sink will not be a corner sink.

There are still quite a few missing details that could help clarify the questions regarding space, size, shape, and requirements.
Please read the post I pinned above in this forum section for idea development, provide the relevant information, and also include the site plan with the house orientation (important for the window considerations).
Thank you 🙂

And: how high are the parapet walls on the upper floor?

Edit: I have already checked and it should be 1.05 meters (3 ft 5 in) for the parapet height. But that also means tiny windows for large rooms! 🙁

How did the total area end up being over 180 sqm (1,937 sq ft)?

Is the furniture layout in the living area planned like this? It seems like a large room, but to me, it looks too clearly divided. What ceiling height (finished height) is intended?

The upper-floor hallway will be dark.

How is the house positioned on the plot? How has the slope been taken into account? What does East-West mean? That on the plans, the top is south? Why are the children's rooms then facing north?

Hello.

The living area is now supposed to be 184 square meters according to the living space regulation. The children’s rooms and bedrooms could have been smaller, but bigger is better.

On the plans, north is at the top. The garage is exactly on the two plot boundaries. To the south, there is 3.5 m (11.5 ft) of space up to a private cul-de-sac. To the west, it is 6 m (19.7 ft) to the street. So, the garden space is minimal.

The ceiling height is 2.55 m (8.4 ft) downstairs and 2.45 m (8 ft) upstairs. The furniture was added by the draftsman. It will look something like this. However, we will probably have a piano instead of a TV. In the living-kitchen-dining area, I am also wondering where to implement transition lines between different floor coverings.

Is the double casement window suitable to brighten the upstairs hallway?
