Approximately 120 sqm, 1.5 stories

Hello everyone, we are currently in the middle of the concrete house planning. At some point, you do become blind to the operation. The plot is about 20m wide and 26m deep. The long side runs from NW to SE. Requirements of the development plan: max 1 full floor, ridge height 9m, roof pitch between 35 and 47 degrees. Ridge orientation SW-NE (along the short side). Planned is a floor plan of 10.50 x 8.50, no extravagances, straight walls, no dormer, no bay window. As for the attic, just to say pure standard: 3 rooms, 1 bathroom with shower and tub. The garage will be built on the boundary line on the north gable, with access to the utility room. Now to the ground floor. Why office/work (multi-purpose room)? Because we are not fans of "office mess" in the living area. Printer, PC, filing cabinet and such stuff should be in a separate room; if necessary, you can also iron there ;). We are currently only two people and have enough space upstairs but that is supposed to change. By then at the latest, the office will be missing. The "kitchen, dining, living area" should be designed open. A heavier opaque sliding door between living and dining and a closable glass partition between dining and kitchen. The kitchen should be shaped as an L and limited by a counter to the dining area (more of a U than an L); a terrace door is planned in the kitchen/dining area. The chimney flue comes into the corner at the top right in the living area. The living area itself is located at the south corner, the house corner is exactly facing south. For me the guest WC with shower simply belongs. My question now is, are the estimated square meters sufficient or are the rooms too small? Kitchen/dining is already quite a narrow corridor. Thanks in advance for your advice and don’t hold back with criticism, no foundation has been poured yet ;)

Please draw with correct interior wall thicknesses and not just lines.

Then the rooms will be a bit smaller again.

The chimney flue will go into the corner at the top right of the living area.

There, where the entrance to the house is supposed to be? That won’t work with the roof orientation. The chimney would then be half exposed. But maybe I misunderstood you.

My question now is, are the estimated square meters sufficient or will the rooms be too small? Kitchen/dining area is already quite narrow.

I don’t see how it works. The utility room can have a width of 2.10, but that doesn’t work for the office. 2.10, so 2.00 meters of usable width... try moving around an ironing board there if there’s also a cabinet taking up some of the width ;)

Also the narrowness, as you already described it, the room proportions aren’t so nice: kitchen with a width of 3.10 (quite narrow), you can only fit 5 decent standard cabinets side-by-side, there must be a 1.20 aisle next to the counter. The workspace between work surfaces should then be larger than 1.20 so multiple people have room to move... so the kitchen will feel longer than wide... it would be nicer to shorten the whole room and make the kitchen correspondingly shorter. That would also be more efficient regarding floor space, in my opinion.

Please draw with correct interior wall thicknesses and not just lines.

It’s just a sketch. The walls are roughly measured as well :)

Cheers Yvonne

If you add the interior dimensions of the rooms located on the 10.5 m long side, you already get 780 cm. Without walls. With an exterior dimension of 1050 cm, the interior dimension usually remains 975 cm ... so your unmeasured entrance/hallway, where presumably the stairs are also supposed to be, does not have a width of 200 cm.

This won't work.

So that you can get a rough feeling for the rooms, take a look at the plan in the thread by , which I last sketched out in more detail -- -- However, the roof there has a knee wall height of 160 cm and a pitch of 22°.

This won't work.

So, our exterior walls are 34 cm... let's take 40 (modern insulation):
7.80 + 0.8 = 8.60... 3 x 12 cm for 3 non-load-bearing walls... =
9.00 (all without plaster)

Oops, I totally miscalculated:oops:, but I only calculated the top 2... math is not my strength today either :)
At least TE sees that it's more complicated, like this without walls.
