Hi Chris The cheapest option is Grind & Seal, but we usually recommend Mechanically Polished Concrete for inside of a home. This is by far a better option, if you were to go for a Matte or Satin finish it is less expensive than a higher gloss finish. Mechanically Polished Concrete does not have a top coat sealer requiring drying and curing time and does not need re-applying in the future which will save time and money in the long run. Because Polished Concrete does not require drying or curing time it can be used as soon as the process is completed unlike the Grind & Seal option. All floors are slippery when wet, a non slip agent can be added to a top coat sealer which would be the Grind & Seal method which we do apply in a shower area if there is not a shower base. Polished Concrete in Matte and Satin finish does have a very good slip rating, has no grout lines as with tiled floors where dust can get trapped therefore it is a wonderful easy to clean flooring solution. Hope this helps, I have provided some details regarding the 2 main processes below There are 2 different finishing processes / methods that are commonly called Polished Concrete, they are very different so it is important that you know the difference & which process/method you want and which is being used on your concrete Polished Concrete - 12 to 17+ step process During this process the concrete is ground to the desired level of stone exposure. After grinding the concrete surface, the Polished Concrete process begins. This process has a densifier applied in multiple stages that is absorbed into the concrete which hardens and strengthens the concrete. A Polished Concrete Floor is Polished in Multiple stages in a Refining Process using diamond tooling & resin pads. A penetrating sealer is applied in the final buffing stage to complete the process The "Polished Concrete" process has "NO TOP COAT SEALER" applied therefore there is no drying or curing time required so your space can be used as soon as the process is completed Grind & Seal (a 3 to 4 step process) This is NOT Polished Concrete. Grind & Seal is often referred to as Polished Concrete, this is the cheaper substitute that gives a "Polished Concrete Look" With the Grind & Seal method the concrete is ground to the desired level of stone exposure and a TOP Coat Sealer is applied such as water based, solvent based, urethane, acrylic or epoxy requiring 5-7 days to dry & cure

I’d go with timber or cork. Cork is great in a kitchen. Easy on your feet and joints and things are much less likely to break if you drop them. Especially as you age, tiles cause fatigue if you are standing in the kitchen for too long. Cork is now available in lots of different colours and styles including charcoals and greys that might compliment your slate. It’s not all 80s orange. Of course timber can look great too. Just make sure it’s ok for kitchen use.

siriuskey, Yes, the courtyard is open to the sky (no roof over it), I assume this is what you mean by double story. Ref. below photos, I would love to get this look, especially the first and last photo, where you can see family living space from the first floor. I can't achieve this in my plan as it eats a lot of floor space upstairs. The referred plan (photos) has a very big void combining staircase, hallway and dining area. I know it is not easy with cooling and heating when you have such a big void. So, I explored a few ideas (with my limited knowledge on this topic) before achieving the current floorplan. I have also thought about, in my current plan, extending the void on the staircase to the dining area (it is more like L shape) but i wasn't sure if that makes any difference. keen to hear your thoughts.
