Fitness Area Planning

I would include it as an extension within the thermal envelope, so that one can heat with underfloor heating in winter and install good shading for summer so that it stays comfortable. During training, you can then raise the blinds

So come on, that's really extremely exaggerated now. But alright!

To the topic: Build 40 m2 bigger on the property, install an air conditioning unit and large floor-to-ceiling windows. Then you can also use the garden as an extended fitness room, which is really cool!

We have ours with 25m² in the basement. However, living space quality with 2 large windows. It's really cool, but if I had the option, then always above ground.

What devices do you have in the basement?

Ideal would also be Bookmarks solution: an extension as a cold conservatory (but without a glass roof), paved floor and sliding doors to the terrace. Then cover the floor with rubber mats and place crash mats in the critical areas. In summer, you open the doors and can also do things on the terrace; for winter, you have infrared heating or a hot air blower. That heats up quickly, 15°C is enough, and it’s only for a few hours during some months of the year. And you also get a playroom for kids or an extra party room.

A cold conservatory should be feasible at 1000 euros/m2. A warm one would be considerably more expensive, at least as much as living space. I would set the ceiling height to 280 cm; that would be good for Olympic lifts or pull-ups. A bit higher and a climbing wall would also be possible.

Better question: Which devices have YOU considered?
