We are facing a decision and urgently need some help.
- This concerns a new build.
- We do not have a basement.
- The heating unit is planned to be located in the attic (according to the plan).
- The total attic area is 60 sqm (10m * 6m), including the staircase area.
- Gable roof, minimum height about 50 cm (20 inches), and maximum height (in the middle) about 2.50 m (8 ft 2 in).
My plan:
- One half (about 24 sqm / 258 sq ft), where the heating unit will be located, will also be used as a storage room.
- The other half (about 32 sqm / 344 sq ft) is intended to be used as living space in approximately 3 years.
The construction company offers the following options for finishing the attic:
Option 1:
For the entire area (60 sqm / 646 sq ft minus the staircase area):
- Underfloor heating
- Floating screed
- Interior gypsum plaster, quality Q2
Cost: 5700 €
Note: The partition wall including door would need to be added separately; it is not included in these costs. It will probably cost around 1000 € extra (?).
Option 2:
- Finish only the part of the attic planned as living space (about 32 sqm / 344 sq ft)
- Underfloor heating
- Floating screed
- Interior gypsum plaster, quality Q2
- AND: partition wall including door
Cost: 5800 €
Note: Could there be potential issues with mold later in the storage area due to the lack of underfloor heating?
Option 3:
- Is it possible to order everything more cheaply?
- Are there any advantages or disadvantages to this option?
I would appreciate your quick responses, preferably detailed. I want to fully understand why I should choose one option over the other.
Thank you very much!

No. Mold does not develop due to cold, but because of lack of air circulation and moisture. An unheated cold attic, ventilated through the roof tiles but dry, will not develop mold. Grandparents used to dry laundry in such spaces. Therefore, I believe the option with the partition wall is more suitable for your plans. This creates a warm room that can be inhabited later and a cold room used purely for storage. Whatever is stored there stays dry, and whether it is cold in winter does not affect the suitcase, the leftover tiles, the Christmas decorations, or the folding chairs for large visitors at all.
