the photo doesn't show a driveway and unable to read the dimensions or see location of existing downstairs doors and windows ...what is the width and length of the existing shed, size and location of all doors and windows and please share a site plan showing distance of the shed to the house and boundaries, location of driveway, direction of north and any special views and, if this is a property larger than a standard house block, why add upstairs rather than building at ground level and how will the studio be used once the house is ready to live in?

OK. Thanks. I’ll get onto your suggestions later tonight or tomorrow. Thanks.

The shed won’t support a second story so you’ll be virtually constructing a new build around its shell. It may be cheaper to knock down and start again on the slab, pending the slab being suitable for the extra weight and footings. Or do you have room to have a prefab/ relocatable cabin trucked in? You can keep or on sell after your project is finished.

Thanks bigreader. We are building around the shell with extra supports and using slab that already exists.

Hi oklouise,
The dimensions are 8900 width east to west and 6100 north to south. Garage is 1500 from east and west boandaries. Below is photo of right-of-way. Windows are on north side as is door. Roller doors for 2 cars opening onto ROW.

Garage was a recent addition, so plans including main house are not available.

So, if I understand your description. South is the ROW, and north is the lawn area. So....the plans you have posted, is the lawn area the same side as the stairs shown on the plan???

please confirm location of existing roller doors and laundry as existing plumbing appears to be on the east not west so something like this might suit

Yes, Dreamer that is correct.

Thanks oklouise,
Your plans are correct except for East should read West. ( Indian Ocean side of house).

But if the grass is the north side, and the ROW is the south, then west and east are correct on oklouise plans.

Maybe confirm the orientation with a compass.

Usually north is at the top of a map, so I think that's where the confusion was. On my map it is south at the top, so east and west are reversed... Thanks for your concern and suggestions dreamer!

Helen creagh, you have said in the original post the plumbing is on the west side, so that would mean that oklouise plan is not correct as it has all the plumbing on the east. So looking at the photos the middle roller doors have the existing workshop, and you want to park the car there in the future. On the west side, with one roller door, on ROW, that is where the plumbing is. Is that correct?

Yes, dreamer. That is correct. Cars are now parked on right side ( west) and middle space ( centre). We must change right side garage to east side to accommodate plumbing and potential toilet and upstairs bathroom.
Sorry for late reply. I’m not so experienced at navigating website…
