Hello and greetings to the community,

My girlfriend and I are considering building a house in the near future.

We already have a plot of land, so that issue is settled.

We have also decided on the type of house.

We want to avoid rising energy costs by building a passive house with solar panels on the roof.

Additionally, we definitely do not want wood as a building material but prefer traditional bricks or something similar.

In terms of design, we want something suitable for aging (i.e., accessible) and therefore a bungalow.

The dimensions for the house are already set: 15.50 meters (51 feet) wide and 11 meters (36 feet) long, which equals about 170.5 m² (1,835 sq ft).

Now to my questions:

- I have read a lot about passive houses online, and one site mentioned that it is almost impossible to build a bungalow as a passive house. Why is that?

- Are the costs for a bungalow cheaper or more expensive than for a two-story house?

- Is there a building material comparable in quality to brick?

- Is a passive house built with solid construction, i.e., bricks, significantly more expensive?

- Is there any way to get an approximate price estimate for our “dream house”?

Many thanks in advance

Regards

Take some time to read through the forum; it is tiring to answer the same basic questions over and over again.

No offense – but some effort on your part is definitely expected, in my opinion.

And a tip for one of your questions:

Why do the Inuit build igloos as hemispheres?
Setting aside structural considerations, I will point out the ratio of surface area to volume. And now to your slab-shaped cuboid compared to a cube.

Your house has 473 m² (5,093 sq ft) of exterior surface area; a typical two-story house with a flat roof has only about 355 m² (3,821 sq ft) of exterior surface area.

I assumed a story height of 2.5 m (8 ft) and an almost square footprint.

First of all, thanks for your second reply, toxicmolotow.

Yes, in terms of shape, it would be a square and without a basement.

The principle of a passive house is insulation and air circulation, so I don’t really understand how that relates to the exterior surface area.

A passive house basically creates an airtight space, so the size of the airtight space shouldn’t matter.

Regarding the first post: Of course, I had already read through this before, but I simply didn’t find the right information, such as a similar building material that is as good as brick.

The larger the exterior surface area, the greater the energy loss (heat), assuming the same insulation.

You will likely be able to build a bungalow as a passive house as well. However, instead of 20cm (8 inches) of insulation, you would need 30cm (12 inches), for example. Just as an example – I am not a professional. The cost for this item would increase by about 50%. Does it make sense? Is it worth it? Do you want it?
