Hi, we are currently working on the exterior design and are also considering the garage.

My wife’s uncle, a trained mason, will help us build the garage ourselves.
Our house exterior is made of 36.5 cm (14.5 inches) Ytong blocks.
We plan to build the garage with Ytong as well.
Here we are planning to use 24 cm (9.5 inches) blocks.

Size is 3.62 m x 9.50 m x approx. 255-270 cm (126-106 inches) high, flat roof with a slope to the back.

I have already calculated the amount of blocks and the estimated cost for the blocks alone comes to just under 2000 €.
This is based on the average price found online per block (so no bulk discount or anything).

Of course, I have no idea yet what the large sectional door will cost, the roof, the ring foundation, etc.

We want to build the garage in a U shape directly attached to the house, so that one side is shared and space is saved.

We have received quotes from IMM Garagen for a timber frame garage at €12,600 with an electric door, one window, and one additional door.
This price does not include the concrete slab or plastering.

Then there is a quote from Fink Garagen, also timber, for €15,000, primed but without plaster or concrete slab.

And another for a steel construction garage from Exclusiv Garagen for €8,750, size 3.50 m x 9.00 m.
However, there are not many good reviews about this option.

Do you think building it ourselves with masonry will be better and cheaper?

Thanks in advance.

If I forgot any information, sorry, just ask and I will try to provide it.

Is no building permit / planning permission required at all?

It is probably exempt from building permits / planning permission, as was the house.

For the installations according to sentence 1 numbers 1 to 4, the boundary-side average wall height above ground level must not exceed 3 meters (10 feet), and the total area of these walls on each neighboring boundary must not be larger than 25 m² (269 ft²)

What wall height is planned?

Not higher than 3m (10 feet), but it is also mentioned right at the beginning, approximately 255-270cm (8 feet 4 inches - 8 feet 10 inches) high

Yes, a height not exceeding 3 m (10 feet) and an area of no more than 25 m² (270 ft²) are not mutually exclusive. You can also choose a length of 8 m (26 feet) with a height of 3 m (10 feet).

With the planned height, it is important to clarify exactly from where the measurement is taken.

And, sorry if a question is asked that has already been answered... when it comes to projects you are not directly involved in, you don’t always have all the facts in mind.

This is an important point.
If your wall on the boundary is 9.5 m (31 feet) long, it can be at most 2.6315 m (8 feet 8 inches) high. Otherwise, you will exceed the maximum allowed area of 25 m² (269 ft²).
I’m not sure if the wall stops before the roof, or if the roof structure, probably 30–50 cm (12–20 inches), needs to be included.

And "it is <<probably>> exempt from a building permit / planning permission" — clarify that, “probably” is not enough.
If the neighbor complains, things will get difficult. And they will only start when you are already finished.

Anything that is explicitly approved will no longer cause problems.
