Dear forum members,

Please forgive my rather basic questions, but perhaps this forum can help me with some answers:

Although it is still somewhat frowned upon by some homeowners, today I started thinking about the construction method using exposed concrete. Let’s assume it is to be applied in an extension to a cubic bungalow from the early 1970s, in a minimalist and purist style. Now to my "working hypothesis":

Assuming the walls are neither plastered nor painted, and for example, the bathroom is not tiled, this should be a cost-effective construction method, especially since the degree of prefabrication of the modules is relatively high.

Is this the case?

How can I imagine the energy performance of this construction method if the walls are not insulated?

If you have a good website with a clear explanation, I would gladly accept it and, beyond that, I am grateful for any help, advice, or practical tips from you!

Best regards

Hello,

Exposed concrete is, of course, a possible construction method. It is also very popular in refined architecture. However, this building technique is anything but cost-effective. This is because achieving a visually uniform and consistent concrete surface requires a lot of effort. Furthermore, using uninsulated exposed concrete for an exterior wall is not feasible due to concrete’s low thermal insulation. Therefore, a sandwich construction is necessary (two concrete layers with an internal core of thermal insulation).

Exposed concrete is thus a building material suited for upscale architecture.
