focus on the facts
Good now! Let’s focus on the facts:
According to the developer, it was not possible to know that we would extend the terrace so extremely (by the way, the terrace is small, what else should one have done).
Your developer sells you a piece of house with garage. The plans include – at least in the building application – among other things, a rear terrace.
Whether it is a developer or general contractor is probably of minor importance here, since the plan for the planned terrace exists. In the best case, one has to adhere to it, whether the developer is the builder or you are.
We paid extra for this garage side door (€850). If we had known about this problem, we would never have ordered the door.
According to the construction plan, the door is accessible because no paving was planned there. So the developer has no obligation or guilt.
The extension of the terrace was proposed by the garden landscaping company, which is in close coordination with the developer.
What exactly is close coordination? The garden landscaper is an external company and receives orders through recommendation?
Do you pay the garden landscaper separately?
Anyway: he is now confronted with your special request as a buyer and realizes that your special request cannot be implemented as is. Is that correct so far ?
If you propose something like that, you have to first point out the dangers and not act as if the builder is to blame.
So far, no one is to blame! The special request is on the table. Then the experts say that it cannot be implemented like that.
So as a buyer you have to dial back a bit with your wishes, where is the problem?
2. the terrace remains as planned, but a lowering/plateau is made around the garage side door
Again: nothing will accumulate if you pave correctly or select the right stones and have it done properly. Accumulations, e.g. leaves, basically gather in corners, i.e. your garage corner,… but since apparently south or west is in front, one could assume that due to lack of wind it doesn’t matter.
And my personal opinion:
yes, exactly, we extended the terrace.
Are you even allowed to build such a large terrace on the small plot? What is your floor area ratio and what floor area ratio is permitted?
I am allowed, but that’s not the topic.
Yes, it is indirectly the topic, because the approved plan has its legitimacy, you want to oppose the approved plan by paving everything, and now – indirectly – want to blame someone.
I also believe that the developer has probably almost exhausted the floor area ratio of 244.5 sqm with the houses and terraces.
If we had known about this problem, we would never have ordered the door.
Ever considered: you wouldn’t have this problem if you didn’t have this special request.
Since I assume that the slope of the terrace has already been taken into account in the calculation by the garden and landscaping company, I would let them do it before the garage structure (door) is affected. Even with a shallow step, it can be lived well. As I see it, the house including garage is about 15.5 meters long. If you look at the garden in front, it really seems that the property ends behind the garage (24 meters). So no large vehicle or even a wheelbarrow will roll through there… and a drainage for rainwater must also be ensured, so a drain for rainwater… now I wouldn’t see anything that would contradict the garden landscaper’s idea. You can then build a step in front of the door towards the house and lay a slope across for the grill to roll. This also brings some dynamism into the sealing ;) Personally, I wouldn’t make a big fuss about it.
Ps in forums without experts people use informal “you”
