Terrace: small budget
You have a few hundred, not a few thousand.
What gets in the way
The trap is buying in the wrong order: three objects that do not go together cost the price of one piece that would have held the room. And in a terrace in particular, the slab is bare and the neighbours can see in.
What seeing it first changes
The budget shows in euros next to the render, so you see what each choice really costs. What moves is the flooring, the furniture and what blocks the overlooking — the walls, windows and doors stay exactly where they are.
