How can I make over a garage into a one room apartment?

You’ll need a bathroom of course. Here’s how we built one with no rough in and without breaking the concrete: https://www.frugalfamilytimes.com/2017/12/how-to-install-basement-bathroom-or-anywhere-without-major-construction-saniflo.html?m=1

Hi Manda, here's a great checklist of things to do when converting your garage into an apartment - https://www.alansfactoryoutlet.com/how-to-turn-a-garage-into-an-apartment Hope it helps

Hello Manda,

You will have to get planning permission from your local Authority to do that and also Building Regulations. Do contact them first, before you start, because if you don't it could cost you dear and be a waste of money. Alternatively call in a local Builder that will have had experience of Garage conversions and ask him for his opinions..........

Thank you very much. I will do it first.

Manda, That's a huge question so let me give you a quick list of things for you to research:

1. Check the zoning where you live to see if a second residence is allowed and what the rules are for things like access (2 doors, parking, etc) because you don't want to make this investment and then not be able to use it.
2. Review building codes to identify everything your apartment will need. Yes it will mean more work but it will also provide safety for the person living there, with things like a window that someone can use to exit in case of a fire.
3. Now you can try out some different floor plans and the best place I can recommend for small space ideas is a walk through an IKEA as they've mastered this because homes are much smaller in Europe.
4. Tips for your layout - keep kitchen and bathroom next to each other to share plumbing, plan out activity centers/furniture and where you want natural sunlight and integrate storage into design.
5. Tips for budget - start with structural changes (doors, windows, framing, plumbing, electrical), then functional (kitchen, bathroom & closet ... IKEA has some nice pieces you can use instead of a closet although you want to consider resale), then flooring, lighting, etc.

Suggest you look at current cost vs value remodeling data to get a realistic idea of what things will cost, starting here ... and good luck.
