Hello,
I have a few small questions for the experts. Even if it’s probably just a fanciful idea of mine, I’m very interested in several details about it.

I would like to build a house and have been considering a few ideas. Maybe you can help me a little?

I’m thinking of a small plot of land, about 150 - 200 square meters (1,615 - 2,153 square feet), and a small concrete house of around 80 square meters (860 square feet).

My idea is a concrete foundation of about 80 square meters (860 square feet), with four concrete walls built on top, obviously with planned spaces for windows and doors. The ceiling would be a simple, concrete slab extending slightly beyond the walls all around. Inside, concrete columns would support the ceiling. These are the parts I wouldn’t be able to do myself and would have to purchase or contract somewhere.

On the outside, I would apply full external thermal insulation and finish it with a rough render. On the roof, a complete solar panel system. Inside, the walls would be covered with gypsum boards, and the floor would have real wood parquet, plus everything else that belongs in a house.

Do you have any idea what the cost for the concrete foundation plus the 4 walls, the ceiling, and the concrete columns might be?

The question came about three days too late. Nowadays, no one will buy that from you anymore.

Just one floor or two? What about the stairwell opening? The fun with concrete will probably be more expensive than building with sand-lime bricks. Alternatively, you could go with pre-fabricated concrete elements. Then the house will be up within a day.

Building with masonry would of course also be possible, but I thought that concrete would simply be cheaper. If I were to use masonry, I wouldn’t even have to hire someone to do it—that’s a good idea. The idea of using columns as support for the ceiling was what I liked best, and I didn’t want fixed walls, but just single or double-layer drywall panels, which can’t support any load.

Just one or two stories? What about stair openings? The fun with concrete will probably be more expensive than masonry with sand-lime bricks. Alternatively, you could go for prefabricated concrete elements. Then the house would be up in a single day.

Just one story, like those prefab houses offered in bungalow style. I had initially thought about planned precast concrete elements as well, but the idea of building with masonry is also great, especially if you use attractive facing bricks in certain areas. You can even leave the walls exposed inside if you coordinate the interior design to match the facing bricks in the interior.

Sand-lime brick and attractive? Well...

Honestly? You can’t do this yourself. You really need professional advice.

No, sand-lime brick is not attractive, but you can use ordinary brick or facing brick in certain areas and leave it visible indoors in some places. Some people have it like that in the bathroom or living room.

Yes, in very old houses... in new constructions, this is only done with facing brickwork or brick slips. The core remains the material the entire house is made of. Differences in stiffness lead to cracks.
