That's quite a mouthful in the title isn't it..
OVERVIEW
On the front wall of my house there's a square patch of dark coloured slate stones, with a square basin under it with the most hideous blue tiles you ever saw in your life; it looks like a square water reservoir as used in Asian toilets. They're also quite worn. The black slab in the middle of the house does not look good. There's goldfish in it, which came with the house. There's a loose plastic pump that pumps water through a dirty plastic box filled with filtering material, blue PVC tubes and a concrete water bird.
GOALS
Get rid of the dark black slab in favour of something brighter yet natural and attractive. It will be a frame holding our company sign, illuminated by halogen lights. [ Instead of a company sign, the center frame could hold anything that looks attractive, like some sculpted sandstone relief. ] The fish basin will be kept as it's pretty much Feng Shui 101 to have some water element on your Northern side with clear, flowing water; gold fish or koi carp are the most common inhabitants of such features. A blue-ish element would still be good for the North side, but new and more attractive tiling will be put in place, possibly those smaller blue-green tiles you see a lot as part of what Thais tend to call 'Bali style' for spas and the like.
There will be somewhat of a mini waterfall of water flowing from under the vertical frame out into the basin, also to get air into the water to keep the fish alive. Possibly those bowling ball shaped rough clay thingies on the corner where water can flow out, though I haven't decided on those.
BUDGET
25,000 baht or so, excluding additional fish. Will include a sandstone brick 'frame', tiling, plumbing for the mini waterfall and electricity for the spot lights. Possibly also a filter-material partitition to keep things fresh.
The white cement water bird will be ritualistically slaughtered.
