Build a garage?!

Hello Andi,

Hmm the only reason for that is the paving of the driveway, which is exactly 4.6m wide on the outside at the garage end ... I'm not completely fixed on the 4.6m, it can also be up to 20 cm less (not much less, because I would like to have the space for a car and motorcycles) but also up to 40 cm more (my government won’t allow much more than that, otherwise her "little garden" would become too small :( ).

In length, I'm "relatively flexible" from 7-8 m everything would be possible ... just not less than that (space) or more than that (wife).

If you work in 50 cm increments, it won’t be quite as expensive. So 4.50 m x 7.50 m instead of 4.60 m x 7.60 m etc. :D

Most precast concrete suppliers say they transport the entire cube to the installation site ... which of course is a problem with that width, especially since our driveway is only 3m wide ... the space between our and the neighbor’s house is 6 m but unfortunately there is a 1.8 m high non-removable fence in the middle :(

They have to work with cranes; obviously.

Do you have any other "ideas" or can I "bury" my project with this "meager budget"?

Send me a PM so I know who I am dealing with and I will send you a contact.

I’m even at the point where I would pave the ground myself and set up a carport with point foundations ... also doing the assembly myself, which I would then clad with wood afterwards. It wouldn’t even have to be a finished carport ... I could get the material (wood) from the local sawmill if I could tell them exactly what I need ... and that’s where the plan fails again (lack of a plan) ...

Talk to my contact; he will probably refer you to a contact person in your region. If that also fails because of the costs – or you possibly are already in contact with him – I have another contact for a carport manufacturer. With this, the project should work – also financially.

Rhenish regards

Phew, what a fun... slowly but surely I see myself burying my garage dream.
Precast concrete garages apparently only possible to make "expensive" within my budget... last offer even when piecing together individual parts was 22k :(
Wooden carport with cladding is basically out of the running too...
That leaves "metal," which I actually didn't want/ want at all :(

I have now talked at length again with a friendly mason and researched online.
What is actually wrong with building it yourself?
In principle (with a little help from the mason colleague) that shouldn't be rocket science, should it?

Speaking amateurishly, I would only need:

0. Structural analysis ?!? - if necessary. around 500 €
1. Strip foundation (+ floor slab) - I have an offer for 2.8k (including earthworks)
2. Bitumen / adhesive for bonding or sealing the first row of stones - costs around 100 €?! (unclear)
3. Mortar for the first row of stones - costs unclear, but certainly not the world
4. Mortar for the rest of the horizontal bonding - costs unclear, but certainly not the world
5. Stones (aerated concrete ?!) for 3 walls + front 2 sides (each 30 cm) - costs completely unclear, I'd have to ask
6. Tools and aids (straight edges, etc.) - max. 500 €?!
7. 1 standard lintel for the side door - costs completely unclear, I'd have to ask
8. 1 lintel > 4m for the sectional door - costs completely unclear, I'd have to ask
9. Sectional door (there's plenty of choice here) - about 3k € (possibly somewhat cheaper)
10- Door including frame - about 500 € (possibly somewhat cheaper)
11. U-profile stones for the ring beam - costs completely unclear, I'd have to ask
12. Steel reinforcement for the ring beam - costs completely unclear, I'd have to ask
13. Concrete to fill the ring beam - I still have everything here
14. Cross beam (at least 12x12x500 ... possibly "larger") for roof construction - costs completely unclear, I'd have to ask
15. Roof battens - costs completely unclear, I'd have to ask
16. Roof covering - costs completely unclear, I'd have to ask
17. Drainage - around 500 € (possibly cheaper)
18. TIME

Do you maybe have a few "estimates" for the points marked in red?

What is still not quite clear to me is to what extent I have to realize a "drip edge"/ roof fascia and especially how the roof construction has to look to get a slope (1-2 %) towards the back.
For better clarity the key data once again:
- WxLxH: 4.6 m x 7.5-8 m x 2.5 m
- Flat roof (covering e.g. bitumen membrane or similar, main thing cheap and permanently watertight) with slope to the back
- Gate: sectional door with electric drive approx. 4x2 m
- 1 side door (simple design)
- Rainwater drainage at the back

Thanks already for your suggestions.
Andi

Did I omit something or rate something completely wrong?

Hello Andi,

I did not respond to your recent post because I will hardly be able to help you – I simply do not know the material prices in your area of Bavaria well enough.

The cost problem you have exists because with WxLxH: 4.6 m x 7.5-8 m x 2.5 m, you are outside the standard, and everything that deviates from the usual always costs disproportionately more. At this point, the price difference compared to a masonry garage is no longer so significant because the advantage of standardized production is no longer present. Assuming 8.00 m in depth, the garage – if you have it built by your provider – should cost a good EUR 22-23k.

Roughly calculated:

Structural engineer: 500
Foundation: 2800
Adhesive/mortar: 300
KS bricks: 1500
Ring beam: 500
Lintel door: 50
Lintel gate: 200
Gate: 2500
Door: 350
Crossbeam roof: 800
Roof battens: 600

If you want to build the garage yourself, of course, you can save money. Whether this will happen to the extent mentioned above, I unfortunately cannot assess; as I said, I do not know the prices in Bavaria. In any case, your purchasing conditions (for the required material) are decisive. If you rely on "normal" retail prices, your above amount in my opinion cannot be maintained. For example, if you can buy the material through your provider and he passes on his discounts, then it could work – if you are able to build the garage largely yourself. If, apart from the structural engineering and foundation, you rely on paid help, I see higher costs coming your way.

Rhenish greetings from the road
