Hello,
we live in a small house (100 sqm living space on 2 floors) in Thuringia and want to expand due to family growth.
The plan was to convert a previously unused attic chamber into a large dormer. Since the floor area of this new room is too small (6 meters long but only 2.40 m deep), the current idea is to let the first floor protrude 2 meters beyond the ground floor. The floor itself should then be supported either by 2 reinforced concrete columns or by 2 extended stone walls. The cantilever would extend over our concreted (still unrenovated) courtyard. Since we find the courtyard cozy and we anyway planned to build an awning or a wooden pergola at some point, the cantilever would be beneficial. We would practically have a covered area on the courtyard, which we could still fully use in terms of space.
We have already discussed various other models with the architect; an additional floor or a complete renovation of the roof frame was also considered, but overall all of that was too complicated, too expensive, or both.
To my question:
What area can the architect actually use here for the calculation?
According to my calculation, a new room with the size of 6 meters x 4.50 meters will be created. But of course on the first floor. Since we have a full basement, I know that the foundation for the steel columns must be laid at basement floor level.
In other words, I have to place 2 foundations 2 m deep because the columns will stand on them, and the actual expansion will be on top. In this context, the roof would also be re-covered at the same time because it still has very old roof tiles.
All other rooms in the house do not need to be "touched."
The architect is only needed for service phases 1-4.
Additional questions:
To what extent can the architect factor in personal contributions in the construction costs?
Would it be easier, instead of deep column foundations for the cantilevered area (6x2 meters), simply to pour a slab foundation? Is that at all allowed and possible next to a basemented main house?
Regards
Volkmar
PS: We have a maximum of 50,000 EUR available.
