When does the exterior plaster come in new construction?

Dear Sir or Madam,

my shell constructor is now almost finished with the ground floor. I am now slowly facing the following question:

When exactly should the exterior plaster be applied?
In principle, scaffolding is set up for the upper floor, which will also be used by the carpenter and the roofer. Afterwards or in parallel, (hopefully) the windows will be installed.

In my opinion, the exterior plaster could be applied afterwards. That would minimize the scaffolding costs.
Or are there reasons against this, e.g. that the Poroton stone first needs to "dry out"?

Thank you all

Good morning.
Before the exterior plaster, everything that should eventually be under the plaster must go into the wall: outside faucet, doorbell, emergency gas shut-off valve (if gas heating), lights, etc.
By the way, the scaffolding is set up differently for the plasterer than for the roofers. The scaffolder must therefore set it up differently from the start and possibly some adjustments will still need to be made.
Last but not least, the scaffolder has to leave the scaffolding standing for you for that long. At least you have to pay for keeping it in place.
Oh yes, if you have a garage that is directly attached to the house, the garage’s roof structure can only be installed/covered afterwards (and the flashing towards the house can only be applied after the plaster). Otherwise, the scaffolding for the garage must be removed. Modifications cost extra each time. (at least with our scaffolder)
So calculate carefully whether you really save money and check whether windows, electrical work, and plumbing will be finished on time – don’t underestimate the stress that can arise from this coordination...

oh yes, drying out is relative - if the stones get completely soaked through in the rain, you actually have to wait a bit

Good morning. Before the exterior plastering, everything that is supposed to be inside the wall under the plaster must be installed: exterior water tap, doorbell, gas emergency valve (if gas heating), lights, etc. By the way, the scaffolding is arranged differently for the plasterer than for the roofers. So the scaffolder has to set it up differently from the start and may still have to make some adjustments. Last but not least, the scaffolder must leave the thing standing for you for as long as needed. At least it costs for the holding period. Oh yes, if you have a garage that is directly attached to the house, it can only receive the roof structure/ be roofed afterward (and the flashing to the house can only be installed on the plaster afterward). Otherwise, the scaffolding for the garage must be removed. Modifications cost extra each time. (at least with our scaffolder) So calculate whether you really save anything and check whether the windows, electrical work, and plumbing will be finished on time – don’t underestimate the stress that can arise from this coordination...

Thank you, I hadn’t thought about electricity and water at all. I will have to discuss that; I doubt they will be finished that quickly. For now, we haven’t planned a garage.

With us, it will probably be cheaper to leave the scaffolding standing despite maintenance costs and renovation work. As I said: calculate and consider whether the stress is worth it to coordinate everything...
