Find an experienced builder in Meadow Heights

I’m converting my garage into a hair salon. I need the bricks covered completely and have it framed And plastered ready to be painted. I want 4x inbuilt arch shelves 2x 1000mm wide and 300m deep coming from the brick wall One that’s approx 1000mm wide & 300mm deep and another that will be approx 2000mm wide. As for height of these arches they don’t need to be same height as ceiling. As for ceiling I do like the idea of having a skylight and open to suggestions as to how that can be framed in the ceiling. I also require the frame work of a toilet built outside (backyard) that will be approx 1000mm wide and 1200mm long internally. The toilet needs to be raised approx 400mm (2 steps) due to plumbing works that need to be done and frame will come off an existing brick wall. I’ll need that plastered also. Ive shared some photos of what I mean by arches. I’ve also drawn a rough plan of the salon layout. I will need to hang mirrors on one side of the wall in case that makes a difference with framing work needed. My garage is on an angle so the entrance that’s from the driveway is wider than the back. I’ve tried to draw it on my rough plan so there’s an idea of how I want framing & plastering to be done so I don’t lose too much space as I get towards the center and back of the garage. - Due date: Before Monday, 24 July 2023 - Due date: Before Monday, 17 July 2023
