Hello Warp,
before you sign, you should check everything carefully. Here are a few examples:
- Mentally go through the rooms and check for yourself if enough sockets are planned per room? Additional costs... (are network cables included as well?)
- Additional costs for a chimney?
- Which staircase is offered? Beech with beech railing or do you want oak with stainless steel railing? Additional costs...
- Conduits in the house for a possible future photovoltaic system, are these planned?
- Conduit for a cistern? Should that be considered?
- Sanitary equipment, what will be charged to you? Often shower trays are listed in the offer, but you want a walk-in shower or shower tray = additional costs
- Are blinds planned for the whole house or only for the bedrooms? How are the blinds operated? By strap or crank? Pay attention to that. Nowadays, the client usually assumes electric, but often minimum requirements are defined = additional costs
And many additional costs = many small things make a big pile!
At least from my experience, you have to check everything very carefully because, as I said, often minimum requirements are offered and not what I considered "self-evident" according to the state of the art or generally the spirit of the times.
Best regards and good luck,
