Basically we have 3 directions to discuss : above, inside and outside of the “plywood”, tego.
1) On the outside.
Really hard to guess : ferrocrete. 🙂 What else.
2 options regarded to workmanship :
1a) outside panels
Ferrocrete poured on the ground … as a panel. Then after a few days it needs to be moved into its final position.
1b) outside fixed
Positioning the chicken wire on the plywood and putting concrete on it.
I would go with the 1a). This way the chicken wire wont undulate at all. In a horizontal position it will hold the concrete easily. We can get away with a really thin layer. It doesn’t have to be that strong so choosing the liquid … concrete used for leveling surfaces should be considered.
Concrete that’s more liquid when poured. However it cost more. so going thinner and paying more doesn’t make sense on first thought. However it’s easier to make … it cuts down the price on workmanship. So the material cost more however the workmanship and the overall cost could be way less. It depends case by case.
Metal sheets will cover it from the outside. A polished beauty … and quality isn’t relevant. In case of 1a) the panels can be moved ulterior. So we have easy access to the “basement”.
Notice that the ferrocrete is quite “tall”. A heavy rainfall will be stopped. It will direct the water far away from the insulation.
2) Inside.
Polystyrene and foam insulation is flammable, Insects could move in it. Mineral wool or batt insulation could work out better. All animals hate it. However in that version we need some material to hold it in place. So it won’t fall inside.
On the electric cables. Batt insulation could work out in a sense that ants and bugs don’t like it at all. Rock wool could be considered. It holds its position quite well. Batt insulation is easier to push into the smaller holes.
3) wooden “beam” on top
Above we used a thick wooden “beam” that’s strong enough to hold 2-3 persons. It’s “movable”. Our way to access the cables and piping. If as a bonus the ferrocrete panels are movable on the facade that’s even better. that would mean : we don’t have to deal with 90* angles to get to the “basement”. We can push long rigid pipes directly under the floor.
The same image again : note this section with the wooden parts.
On the PINK wood : we have a metal protection on the outside. Wooden piece in between the frames of the windows is BLACK. It’s not glued. Maybe silicon.
Provides easy access to the window panels. Might need a thin layer of sponge like material in between. Depends on climate. Easy to remove.
Ferrocene water protection (DARK BLUE)
Easy to remove elements to access cables (LIGHT BLUE / RED).
Wooden slab that holds all the elements between windows (yellow). Notice the insulation comes till that. Made an error with the representation.
A repair can be done “easily” this way. Plug and play elements. No need to transport your window to a factory and wait for days. No need to pay expensive workmanship and machinery to do the repairs. One panel broken, one panel changed on site.
We used lots of gravel / rocks. Water won’t reach the house. Notice the drainage pipes positioned on the outer part. Between the rocks and earth I would use ferrocrete or HDPE sheets.
HDPE drainage membrane one of my favorites or ferroccrete panels. What else 🙂 Both are good choices. On the video we cans see the ferrocrete/ hdpe panels and the black is the thin metal sheets … finishes that covers and protects the wood /tego – plywood. The structure itself.
Choosing big round rocks instead of a concrete finish at the terrace it would have its benefits. It wouldn’t be destroyed in 8-10 years (than tiles).
Check out the examples on pinterest.
Reinforced ferrocrete / concrete slabs could form the walkway. Positioned right above the rocks. Shown by dashed lines.
This solution can skyrocket life span. Water droplets won’t destroy the building in a direct way. Let me explain : usually the water splashes back from the concrete sidewalk … a thin layer of microbes and earth gets back to the facade. That holds moisture …. therefore it feeds bacteria and mold even better.
The big overhangs will prevent water splashing back to the facade from the ground. Huge round shaped rocks won’t let the water splash on the glazing or onto the walls. It ruins the angle of the fall.
This walkway can be built quite easily and fast. Even by those who are not the best craftsman at all. That means : the workmanship gets way- way cheaper and meanwhile we have better …literally eternal finishes.
The speed of construction is really fast. No need for several layers of concrete and tiles. No need for dozens of large teams of craftsmen on site.
Note that the shaders protect the structure as well. In case of a huge wind….they are pulled up automatically. We can double the shaders in the inside as well so privacy is preserved.
