Hello Forum,
We are currently planning a basement for our single-family home. In addition to the building services room and a laundry room (washing machine + dryer), there will also be a gym and a study.
The four rooms will cover an area of about 65sqm (700 sq ft). The ground is suitable for this (from approximately 2.5m (8 feet) of medium-density gravel layer according to soil report – load class 2 according to waterproof concrete guidelines). The basement will have perimeter insulation (exterior walls, floor slab, basement ceiling) – the design is currently based on KfW 40 standards, which require thicker insulation according to advice from the forum 😉 The study and gym will have underfloor heating. The study will also have a light well. The gym and laundry room will have light shafts. The building services room will have no windows. The floor will be continuously laid with anhydrite screed, followed by a floor covering. Electrical installations will be surface-mounted on the walls.
The additional construction costs (especially setting out the building grid and excavation of the foundation pit) are not included in the costs. I am currently budgeting about €1250 per sqm (approximately $130 per sq ft), which is about €81,000 for the basement. However, everyone looks at this price as if it were a car and says that €35,000 more than enough? What is your assessment?
Best regards,
Andy

We invested the money elsewhere and are now very happy without a basement.I consider myself part of the "(when in doubt) go for the basement" group, but I’m happy for anyone whose plot of land offers the option, in case they prefer to belong to the other group.https://www.instagram.com/11antgmxde/

I personally belong to the group that prefers having a basement "when in doubt," but I’m happy for anyone whose property allows them the freedom to choose, if they prefer the other option.Excuse me? What do you mean by that?

Sorry? What do you mean by that?Well, you do know my basement formula. Those who want to avoid having a basement need a plot of land where the terrain's slope works in their favor.https://www.instagram.com/11antgmxde/
