ᐅ Terrace on a Sloped Site Supported by Stilts – Which Is Better: Wood or Steel?

Hello everyone,
I need your input because our eastern neighbor has disrupted our landscaping plans. We had planned to stabilize the area with two rows of 1 meter (3 feet) L-shaped retaining walls. Now, our neighbor intends to build three full stories facing the garden, meaning they will want direct access from the basement to the garden.
This makes our original plan obsolete since we intended to add fill while they plan to excavate. This would leave us with 2.5 meter (8 feet) tall L-shaped retaining walls on the side, which none of us want.
So now the question is, do you have any idea what it would cost to construct the terrace on a supporting framework, possibly including the tool shed? See the screenshot. We would need to expose the basement wall facing the garden, but then we wouldn’t need to install the L-shaped retaining walls, which would cost around €26,000.
Would wood or steel be advisable?

An HEA100 beam weighs approximately 17 kg/m (11.5 lbs/ft), and one kilogram costs about 2.50 euros net (including structural engineering, delivery, and installation). This way, you can roughly calculate the cost yourself.

For a steel structure made of galvanized HEA beams, I would estimate around 7,500 euros. I assumed 45 meters (148 feet) of HEA100 beams. Pure material costs are about 2,500 euros; the rest covers structural engineering, assembly, delivery, and corrosion protection. Then you still have the shed or carport and the foundation work to add.
I wouldn’t build something like this from wood, the maintenance effort would be too high for me. According to your calculation, I’ve come to roughly the same material price. Then we only need to add the wooden floorboards, structural engineering, assembly, delivery, corrosion protection, railing, and the contractor’s cost margin. So, we could budget under €20,000 without the carport? Although “budget” is an understatement since the loan is already secured.

In my opinion, this construction is the most cost-effective I will outline an alternative concept for the supports and spans as I envision them:

I’ll sketch out how I imagine the supports and spans:
Are the blue blocks supposed to represent the steel columns? If so, the L-shaped blocks at the carport could potentially be "repurposed" as supports or beams, right?
The idea also has some merit and would almost match the "old terrace size."

Then the L-shaped concrete blocks at the carport could be "misused" as supports or beams, right?Exactly. Relying on two different construction methods doesn’t really work.

Relying on two different construction methods is flawed.Why? At least you could save the two supports at the carport. Nothing more, nothing less. The cross beams would still be required.Similar topics
