ᐅ Uncertainties regarding size, planning is otherwise mostly complete.

Good morning!

We are about to finalize the planning for our single-family house; we want to build 1.5 stories with a knee wall of 150 cm (59 inches), keeping it as compact as possible. So far, we have been very satisfied with the design from the planner of the construction company, but now that I’m working on the interior layout, the combined living-dining-kitchen area feels a bit cramped. We definitely want a seating corner in the dining area, but I’m afraid that might be difficult to fit (kitchen + seating area). Now I’m considering whether we should generally enlarge the house so everything fits comfortably (from 10.13 x 9 m (33.3 x 29.5 ft) to 11 x 9.5 m (36 x 31 ft)). Maybe someone here has some helpful tips?

The house has a basement, the clear room height in the living areas is 260 cm (102 inches), and a pitched roof with dormer and a 35° slope is planned. The plot is about 900 m² (9700 sq ft), with a 3-meter (10 ft) setback required from the neighbors. Two parking spaces (carport) at the front by the street are included in the plan. Thank you very much and best regards

The unusual dormer is probably more expensive than simply building the walls up to full story height all around, and double casement windows usually look quite odd with today’s roof insulation thicknesses.

Hello

I find BeHaElja’s suggestion much better than the original.
However, I would add a small hand wash basin in the toilet.

That is not a dormer, but a cross-gable roof projection.

From a 1.50 m (5 feet) knee wall to a 2.80 m (9 feet 2 inches) clear structural height? That costs more than a cross-gable roof projection.

1.30 m (4 ft 3 in) x (10.13 + 9.00 + 9.00 + 10.13 - 0.365 - 0.365) x 0.365 = 1.30 x 37.53 x 0.365 = 13.70 cubic meters (cbm) of masonry.
220 EUR x 13.70 x 1.19 = 3,586.66 EUR (monolithic aerated concrete)

Interior plaster (10 EUR), exterior plaster (20 EUR) on an area of 1.3 x 37.53 = 48.79 square meters (sqm)
48.79 sqm x 30 EUR x 1.19 = 1,741.80 EUR

Masonry and plaster = 5,328.46 EUR

And what does the dormer cost? Are all the numerous additional connections really achievable without thermal bridges? What are 5,000 EUR in a house construction project costing 400,000 EUR or more (including land and all purchase and construction incidental costs)?

P.S. I really just asked about the costs per cbm of exterior aerated concrete masonry (lambda 0.09) recently. The values for interior and exterior plaster are now roughly estimated.

Of course; why wouldn’t they be?

In your calculation example, some items are missing that any responsible builder must consider; after all, they want to be active in the market for many years.

I’m a bit torn – before our build, I would have definitely said that a two-story house is better than a single-story. Now, after spending about a year looking at houses inside and out, I see that two-story homes often look like a box, while single-story ones often resemble a Cape Cod style (there are exceptions, but I can only afford limited options).

We built with a knee wall height of 1.6 meters (5 feet 3 inches) since we had to go with a single-story design. The rooms feel nice; the tiles are installed now – I’m not sure if I would have liked a two-story house that much better after all. I’ll update again after furnishing it.
