I have just taken a couple more pictures (excuse the untidy house) from the stairs. As you can see it's an open plan area that isn't that big but very high ceilings also in wood (Macrocarpa) with dark wooden beams. The house is surrounded by bush so quite a dark house. I initially considered a darker wood similar to the beams but not sure if that will make the house appear smaller / darker...I'm really not sure what to do!?!?!? Thanks

Do you want to keep the wood floor? It is rare to see wood floors as garage floors. I've seen homes like this moved onto pour basement slabs (same concept as pile foundation...but with a basement instead of dirt. If you want to keep the wood, then there has to be a way to keep the wood off of the concrete. An 18" crawl space (dirt covered with 6mil poly sheeting or cement) is always an option. The 18" crawl space would have to be cross vented/heated properly. This is for "keeping" the wood. Flooring. I'm not sure what has to be done to remove the wood floor and have the building sit (joists and all) on concrete. Remove the joists and you have plenty of stability problems. You would need to speak with a local architect/building engineer who has some knowledge of what you are trying to do, soil conditions, etc. to get this right. In theory it can be done (we've just landed a small car on a comet...we should be able to put an old building on a cement slab)...I'm wondering about the expense to get it there (excavation + soil stabilization + concrete + piles, etc).

Hello There: Your home looks like it has some good bones and period features. No one has yet to comment on marrying subway tiles on lower walls, with tongue and groove cladding on upper walls of your space. I am thinking this finished look could well end up looking quite "busy." Lots of competing "grid" lines, etc. If I understand correctly, this space is actually, or ultimately will be, a bathroom. Perhaps you do not want a wood product on lower sections of the walls because of potential water damage, etc. That said, there are excellent paints, sealants, etc., that you could apply that would guard against this. If painting, using Zinsser Sealant as base coat is a good starting point. As another alternative, you could use much larger tiles on lower portion of walls, oriented vertically. I am thinking 12" x 18" (or 24") tiles. Of course, these are more challenging to install, given their greater size and therefore, weight. Despite this, if you have an excellent tiler, it can definitely be done. For example, you could choose glass tiles, either clear or coloured. Going even further, you could install glass panels to lower sections of walls. You could "back paint" them or not. You could apply paint or even wallpaper (with a wonderful design and colour way you'd likely never tire of) prior to installing glass panels. The wallpaper idea, especially if design is more curvilinear in nature, would not be competing with verticality of tongue and groove, but rather, would complement and enhance it. If beautiful wallpaper (or heck, even a mural or timeless design could be painted directly on walls) is applied and then covered with clear glass panels, the overall effect would be akin to that of an art installation. Naturally, glass panels would be considerably more expensive, but would provide a more seamless, less cluttered appearance. Should you like this idea, simply check what thickness of glass would work best, both for aesthetic and safety purposes. If you have a bit of time to shop around for best supplier and price point, you could well suss out a source that will not "break the bank!" :) To affix glass panels to the walls you want to use hardware that is anodized. As an idea, you could use anodized lug nuts that are usually used for automotive purposes. I just looked up "anodized lug nuts" and see they are available in wide array of wonderful, decorative colours. This hardware would be visibly holding your glass panels in permanent place, but they would be a small attractive design element, ultimately adding another layer of visual interest to your space. I believe glass panels would tie in very well with your great, textured/mottled glass panelled door and transom. Too, I think the overall look would achieve a really attractive marriage as various materials, along with period architectural features would "read:" old, new, and timeless. I realize this design concept may seem counterintuitive to you and/or others, but I can "see it" and think it could be just fab! All The Best, Sharon Black, interior designer and contractor

Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)
