Some of you in this forum might remember on several topics I've started on building bigger tank, attaching glass to concrete, slow UGF system, etc. They serve as part of simple research.
So here I review the whole thing and throw into a journal : sunken garden project.
Background : House under renovation. We used to have a space inside the house which is basically a huge terrarium cliff. The space measuring around 3 x 3.5 meter and some 5 meter tall and heavily planted with vines such as pothos, phylodendrons, etc. They live from an opening at the top (no roof) measuring 3 x 3 meter so sunlight could penetrate in for several hours. The decor of the thing is already too old and does look so much artificial (made in late 70's), so it is put down with the renovation. Since we love it such so much, the renovated house will feature the same garden at the same spot (which is inside the house right by the living room) but this time with much more realistic decor and a simple aquascape to spice it up.
Green : garden area
Light blue : void
Blue : second floor
Grey : stairs
(it used to look something like this in the past, with the walls textured and planted. If you notice the white strip which shows a man standing compared to the structure).
And so the garden was demolished along with heavy renovation project on the house. As renovation started, the garden was stripped to bare walls.
Going to drawing board, I came to a concept of making a paludarium thing that looks like a piece of nature scene, cut it and intall it in the house. That is of course complete with the cross section on the scenery which includes a cut of the water... and that means installing a plank of glass on one side to view it all.
I looked around for a decent landscaping and architectural contractor and end up with a company which occacionaly deals with great natural projects on hotels, apartements and private houses. As I have no capability of building this without a team and the expert in making highly artistic artificial rock/cliff gardening, DIY this kind of work by myself is almost impossible. High craftsmanship is needed and hundreads of hours will be spent even by a team of 3-4 people.
I made a top view concept of the sunken garden like this :
1. Water section of garden
2. Glass for viewing
3. Floor (lowered)
4. Dry section of garden
5. Filter compartment
6. Floor (raised)
The glass part of the pond will measure around
1. 150 x 60cm
2. 200 x 60cm
and feature 19mm glass, open top style.
From the lower floor to the base of the pond it will be 25cm deep and the raised portion is around 50+cm, thus making the total depth practically exceeding 75cm.
The dry section of the garden, which is raised from the water section, will be integrated with cliffwork to form realistic scene which resembles what you can find in tropical waterfalls/dripping cliffs. Pockets for planting area will serve as starting points for terrestrial plants, climbing, aerial, epifits, mostly medium to low light plants including but not limited to : ferns, bromeliads, pothos, ivys, phylodendrons, orchids and many kinds of forest floor plants.
