Hello everyone,

We are still in the early planning stages for our house, as we are waiting for approval for the building plot, but I have the following question in mind for which I haven’t yet found reliable information here in the forum or online:

Does anyone have experience or information about whether, and if so approximately how much, the cost difference is between building a masonry double garage with a pitched roof, for example, versus covering it with a terrace (including a roof extension with 1.0m (3.3 ft) height according to the development plan)?

The theoretical practical value of a terrace on the garage is obviously much higher, regardless of how often it would be used.

I’m just wondering if there are significant cost differences here?

I’m leaning more towards a standard roof, but if the terrace option is significantly more expensive, I would rather go with the terrace on the garage.

Best regards

Preliminary question: Garage built on the boundary line?

If yes, obtaining approval for the garage including the terrace on top will be difficult....

Yes, the garage would then be on the property boundary.

I assume it would be approved because the development plan clearly states that a roof terrace can be built on the garage, provided that the roof terrace has a parapet or roof edge at least 1.0 meter (3.3 feet) high.

Whether this applies only to garages located within the "normal" building zone (i.e., the one for the main single-family house) and not to garages in the "small" building zone (5 x 2 meters (16.4 x 6.6 feet)) is not clearly specified in the development plan.

I would clarify the approval-related question in advance if this issue becomes concrete.

For now, I just wanted to research which solution would be (significantly) more expensive.

Hi. We are planning something similar. The gable roof costs us exactly twice as much as the flat roof option.
Due to this requirement from the development plan / zoning plan, we decided on a green roof.
The cost for a double garage made of steel, including an electric door and a 3 x 2 meter (10 x 6.5 feet) shed attached, is 11,500. The gable roof is 20,000.

Waterproofing of the flat roof garage included for 11,500? That sounds a bit too cheap to me.
