This will be my first post, a Parisienne friend pointed me at this forum.

I bought a house recently and it's got a somewhat larger garage than I previously envisioned myself enjoying but, well, I'm sure I'll find a way to use the space..

We've a family with 5 cars, three of which are really just country lane touge toys (2x na6ce and 1x zzw30)

I'm posting up here sort of looking for inspiration, feedback, ideas, etc.

Layout:

Layout.jpg

260m2 rectangle.
Floor of 12 4.5mx4.5m concrete slabs.
Comprising 27m x 9m total in two sections.
Inner corners/joins of the concrete slabs come to a column that helps support the roof.
18 x 9 in the inner part and 9x9 in the 'entry' part - there's a wall dividing the sections with a wooden door large enough for a car to pass through.
Height around 2.3m at its lowest to maybe 3m at its highest - it's a sloped roof with the slope 'down towards the sun'.
South side has a few windows but they only really light that half of the garage.

It's currently _empty_ bar a single water heater for the small annex.

Usage:

Definitely:
Parking Cars.
Wheel Storage/Display (All the wheels!).
Parts Storage.
Workshop for f-rkin about. Probably will get a 3d printer to put in it and it'll house my drill press and tools and so on.
Solar Paneling on the roof and a place to keep the batteries for all that.

Maybe:
Car Lift /or Maybe a chassis dynamometer.

Works:

I've had the concrete slabs epoxy coated, it's curing now. Cost around 3 grand total. Seemed like a sensible first step.

Future works..

Roof:
Roof is going to need replacing before solar because I refuse to get solar installed on top of asbestos. That'll be the next major work.
Also the new roof will need to insulate against heat properly as the asbestos seemed to turn this space into an oven in summer.
Also there's the option to raise the roof at the same time as replacement... I could go 'storage above' with a raised section, if it was higher it'd be even more efficient on leaving the floor free.

It needs much better lighting - currently it's naff bulbs but that's an easy fix with some LED strips.

Walls: Need cladding

The columns will need some soft cladding so if someone touches them or opens a car door against them the paintwork damage is minimized.

Thinking of a decent storage solution against the back wall. And wheel display/storage.

There's an inner door that is deeply annoying because it sort of dominates the space before and in front of it.

There's no outer door - it's just open to the elements, so I'm planning to put a sliding door on the inside(or outside?) to provide some barrier. Inside is probably easier and more secure.

I'm tempted to put in a small cabin type office/server room where I maintain a cleaner environment. There's no point running aircon for a full space like this, even if the electrickery will be free once solar is done.

Ideas ? Thoughts ?

Diagram and photatoes attached. Blue floor is now it's empty and curing. Full of carp one is from before I bought the place. Layouts show what I might do, but it's completely empty currently.

OK. We're actually moving into this house soon. I've got some problems and some ideas.

We've got an asbestos roof, and it's expensive to rip out (has to be done by an authorized company, masks etc) - just getting the old roof removed will be 7K. Probably in for another 7k to put a new one on, minimum.

Summer is coming and it's hot to have a roof like this, very very hot. I'm thinking of how to cool it. I've got a big-*** well out the back and I could run a perforated hose across the top of the roof and let it do evaporative cooling, combined with a solar-panel driven pump. The well needs to be flushed out anyway (it's been left open for years) so it'd make sense to run the water somewhere I'd benefit. I can also recover anything that doesn't evaporate into the old (now unused) septic tank. Once I put in some guttering..

I've got a lot of leftover cladding materials from the house also, I can use to insulate the walls.

I've started buying shelving to go in, also.

Welcome to the website. I've been in Spain many times, always enjoyed visiting the different parts of your country. Hope you lie it here. A lot of potential for your new residence.

I've bought the water pump / controller / solar panel and enough wiring and sealed connectors to get it in. I've got some builder friends who will help me put the hose on the roof and attach the solar panel appropriately.. and also sort out some ventalation.

I suspect part of the issue is that there is no 'vent' for hot air to leave by. I need vents both at the bottom and the top to allow air flow out efficiently, that is from left to right.

Per this image there is no explanation of the vertical dimension, but the roof is on a gradient, on the left side it's around 2.2M high, on the right side it's around 3.2M.

I think I need around 1 'vent' per square. - 10 vents total, installed on the left as low as possible, on the right as high as possible. - the left side being south facing (I'm in the northern hemisphere)

OK - so an update. We've lived here for a year now.

Vents are done, they made a difference - When we put them in the hot air blasted out at some speed.

The space remains dominated by 'house moving boxes' still. But it's still too damned hot.

I finally installed the well pump and a solar panel setup, since I'm preparing to put in multi-stage biochar water filtering setup.

I have now gained two a pair of used 1000L IBC totes for peanuts (130 euros for the pair, delivered) - one to be a header tank for the water filtering system, the other to be a header for garden water.

How I'm going to deal with the heat in the garage will be so: I'm going to run a soaker hose across the top of the garage roof.

Will run the well pumped solar to the garden water IBC tote with a float valve. In sunshine it'll fill up the tote first and then water will head up to the roof. Will run non-soaker hose to get to the start of the soaker hose.

I'll probably run a similar setup to the water filtration header IBC tote but we will see. Maybe it'll be from the same solar pump, Or perhaps I'll stick another pump and solar panel in.

I guess the idea is that if the sun is up and the two totes are topped up, we can just dump excess water on the roof.

Regarding the Asbestos situation I'm told my region will have public funds available to *cart off* Asbestos this year, and I'm in a queue with a local company to apply for that. I'm going to reach out to a friend's dad who was a politician famous for making good use of public funds with the local council when he was mayor, in order to work out what really might happen. I want to put in solar panels....

*cart off* being a euphemism for some very expensive hazmat cosplay.

I put the soaker hose up a few days ago and I can confirm that the theory works well. The roof is corrugated and the water obviously falls into the lower part of the corrugations, but it works fine.

40c roof goes to 25c roof in about two hours, at least where the water goes, I need a slightly higher flow pump to get enough to soak it thoroughly.

Water out the well is clean and cool, so we're in luck.
