Cost of garage

walter johnston

Cost of a garage- ballpark
10 x 7 metres external
concrete floor insulated as in a house
walls insulated with insulated plasrterboard inside
plumbed for toilet, shower and small kitchen
10 double plugs and lights on ground floor and attic space
attic space must be reasonable at least 350 sq feet + ceiling well insulated
attic space with 3 velux and one side window at apex of attic
12 feet wooden doors and one normal entry door

any idea of the costs assuming groundwork all done
many thanks

Moved that to its own thread

That would be good to know, something I plan on doing, having a small garage with an extra spare room upstairs.

On a side note, whats the legal size you can make your garage without requiring planning. I heard it was 20ftx20ft, but not sure...

See Q.7 in this doc.

your garage is 630 square feet - allow approx €40-45 per square foot. You could get someone to do it in Timber Frame. You didn't mention the roof - assumed concrete tiles to match your house.
Kingspan insulation for your floor
300mm insulation in the ceiling
If you are doing block - blow in insualtion as opposed to aerobord
plasterboard inside - I wouuldn't do that unless you have a specific need.
Are you planning to live in it - or convert at a later time to a small flat for a family member - seems like it. The issue would be planning. Again I assume you have planning permission for this size.

If the weather was right I'd expect it to be completed with 4-6 weeks.

Remember that most grants of planning permission stipulate that a garage can not be used for human habitation. Even if this isnt mentioned it would still need planning permission to add in a granny flat. The max size of a detached garage is 25 SqM and it can only be built to the rear of the dwelling.

Its open to debate if this means that it cannot be visable from the front elevation or just that it cannot be forward of the building line.

Thanks for that
I was hoping to build much bigger than 25sq mtrs , I presume that planners will let you build a larger building ie a garage and store room etc. It is in the country although there is a neighbouring house. the plan would be to build it into the back of the hill( house built on a gradient so 15 feet hill at the back)
the garage would start somewhere at the back of the house .

Also considering adding to the end of the house but unsure

thanks
