Hello,
6 T€ for a prefabricated garage: I assume that neither windows/door/sectional door/green roof (usually required in the development plan) are included here, right?
Correct. Currently, a prefabricated garage 3 x 6 in the Rhineland costs €4,588.00, 2 strip foundations €895.00. For Hesse, I simply calculated a flat surcharge. For the rest – except green roofing – I am calculating another €2,200 here.
20 T€ for painter & floors as own work. You surely mean including tiles. Under "EL" I understand only material costs, and 20 T€ is already very high.
EL also means own work = material worth €30.00 and painting or laying it oneself. Examples: A client takes "only" woodchip wallpaper for the walls and €20.00 tiles; for a single-family house size 140-150 sqm they might manage with around €12,000. The next wants to paint the walls, takes tiles worth €20.00. Should – with own labor – also be manageable with €15,000. But there are also clients who opt for expensive wallpaper and choose higher material values for the floors, then €20,000 can already be too little. Therefore, I always assume €20,000 as a median value. Upwards always open.
Rhenish regards
