Undercroft garage

9 years ago

We live in Perth, Western Australia, and we are contemplating building with an undercroft garage. Can anyone tell me how much extra it costs to build an undercroft garage instead of a normal garage? Thanks

Hey there, did you make any decisions on this? If not, perhaps consulting your builder or designer may help in this situation.

Hi. No decisions yet. It will come down to cost I think. I will definitely chat to builders. Thanks

Great to hear that you have decided not to paint the brickwork. Can I offer my opinion - I'd suggest painting the garage door and surrounding frame and the adjacent beam and column (currently white) in a dark charcoal/brown to match the ground floor brickwork try Dulux Namandji or Mali. I would redo the retaining wall with large boulders in a more freestyle layout than the current straight line and take up some of the concrete drive near the retaining wall to create a garden on the lower level, curved to still provide access to all of the undercroft unless you wish to enclose part of it with a large full height window. I'd love to see the wrought iron balustrade painted black. My home in the mid sixties had salmon coloured bricks, white window frames and fabulous turquoise gutters! The downpipes were painted to match the bricks thankfully - turquoise might have been a bit over the top! Good luck with your project, would love to see your progress. W

I wouldn't replace the fibre cement panels under the windows with weatherboards, that would just accentuate the different window heights. Instead I would paint those panels a darker colour, say a charcoal grey, with the corner posts and other window trim in the same colour. (You are right, grey is timeless, while any blue would date very quickly.) Then the windows and panels become consistent vertical elements on a lighter facade. You can also pick out the fascias and gutters in that same grey to tie it all together. If you stripped back the brown painted battens to the undercroft and the balcony timber railings, and instead gave them a coat of decking oil for natural timber warmth and integrity, you could make a similar oiled horizontal batten front fence using hardwood decking boards on 50x50 galvanised steel posts. Then the fence and the undercroft battening would match. If the garage door is a tilt-a-door I would be tempted to replace the steel with oiled horizontal battens. Otherwise, paint it the same charcoal grey. Then you have a 3-tone colour scheme that will give the place simple understated elegance: White, grey, and natural oiled hardwood. I am curious why what looks like the front door is not accessible? It looks like there might have been front steps there at one time instead of the current deck. Probably a casualty of a previous renovation.

I've seen this topic raised before a few years ago but never really answered to its full extent.. now that a few years have passed, who has completed an undercroft extension and what was your journey (and costs, process, any new technologies, pain points) like? Ideally in Perth but good to hear from other states too. My story: we live in Perth, Scarborough and are looking to extend/renovate. Our property is at the back of a battle axe block at the top of a very steep drive way. The front is heavily retained and is where we would like to add an undercroft garage. I know the exercise is not going to be a cheap one - chemical grout injection, plus earth works, plus difficult access. Regardless, I want to have the work appropriately scoped out and priced as I think the upside down the line will out weight the cost. To save on costs I was thinking we could not excavate all the way down to the point where it keeps the current front area level (refer to second picture.. i.e. have a 1-1.5m rise). Yes, not ideal to have multiple levels at the front but there needs to be some give and take. I was thinking the newly raised area could be a deck area which would take advantage of the views in any case.

Wow...again!! That would be sooo helpful thank you! Problem is I am not there yet as awaiting settlement on my place in October then shifting to SA from Vic. I only have an aerial photo and have just paid deposit with settlement coming late Oct. When I get over there I can draw up a simple plan and give description of all the materials in the existing buildings. Would also give my vision and wishes with the hope that some talented HOUZZERS will come to my rescue! :)

Hi - In my experience undercroft Garages would usually add anywhere from $50,000 - $100,000 to the cost + the cost of additional house area. It all depends on the size of the undercroft area, exactly how far under ground level it is (eg how much retaining is required), additional engineering to span the slab above the Garage plus a set of stairs at least internally & possibly externally. It's a great idea for gaining some extra space, but something that I would only entertain if the site particularly suited it or the cost wasn't an issue. Hope this helps slightly & all the best with your project!

Hi Tana, I'm interested to know whether any builders were able to give you estimates? We are also in Perth and considering an undercroft (we have a narrow lot with 5m variance, sloping upwards to the rear) but so far know one we've spoken to has been willing to provide estimates without plans. Although I understand this, we are in a predicament given we are trying to avoid extra expenses that come with redrawing plans (we have been told it would be a whole new set of plans rather than an amendment if we changed our minds about the undercroft) so are trying to ascertain feasibility before hand. However this is proving so difficult! Did you have the same issue?

Hi Loujz, I never actually got much further in researching it as we decided not to run with the undercroft for totally separate reasons. Good luck with your research - it is certainly not easy.
