ᐅ Build the garage yourself or not? Which option is more cost-effective?

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.

Rough floor plan: House with garage facing the street, hand-drawn.

This is roughly what it would look like. I know, it’s a poor sketch, especially in terms of the dimensions.

But yes, the 9.50m (31 feet) would directly border the property line of the first neighbor.

So why is that considered too long?

Because (most?) state building codes only allow garages up to a length of 9 m (30 feet) as boundary structures; otherwise, a 3 m (10 feet) setback from the property line is required.

So the development plan does not apply here?

I have just read the following in the Hessian Building Regulations:

10)
1
Without a setback area, and either directly adjacent to or with a minimum distance of 1 meter (3.3 feet) from the neighboring boundaries, the following are permitted per building plot:
1. Garages including storage rooms or areas,
2. Covered driveways to underground garages,
3. Secondary buildings for storage purposes,
4. Secondary buildings for local supply of energy, cooling, or water,
5. Up to three parking spaces,
6. Fences, privacy screens, and terrace partition walls in commercial and industrial areas; outside these building zones, up to 2 meters (6.6 feet) in height above ground level,
7. Retaining walls to secure the natural terrain,
8. A wood storage area with stacks up to 1 meter (3.3 feet) high above ground level and 6 meters (20 feet) in length per plot boundary,
9. Solar installations on buildings or building parts listed under numbers 1 to 4, with an average total height of 3 meters (9.8 feet),
10. Freestanding solar installations with an average height up to 3 meters (9.8 feet) above ground level and up to 9 meters (30 feet) in length.

2
The total length of boundary developments for the installations listed in sentence 1 numbers 1 to 5 must not exceed 15 meters (49 feet); roof overhangs are to be included.

3
For the installations mentioned in sentence 1 numbers 1 to 4, the average wall height facing the boundary above ground level may not exceed 3 meters (9.8 feet), and the area of these walls at each neighboring boundary may not exceed 25 square meters (269 square feet) in total.

Which one is relevant for you, Hessen or BW? Your profile here says BW.

The profile is no longer up to date, we have moved to Hesse.

must not exceed a total of 15 m (49 feet); roof
overhangs must be included.

If this applies to your building plot, then you should follow it.
If it is not regulated, the mentioned 9 m (30 feet) guideline would probably apply.
If in doubt, just ask the building authority of your city or district.
