Layout optimization of a settlement house

...
In addition, there is the garage with a "difficult location" and the basement, which will probably be partially developed.
With incidental building costs, you have the 5 before that.

Yes, then you start to wonder whether you really need such an airlock.

I also think 500k plus the [Grundstück] is quite realistic, 300 impossible, and 400 an absolute bargain house with a lot of own effort.

Laundry chute is difficult because the utility room is not located under the bathroom.

I would consider the entire plan as a sample drawing for now.

This is a widespread misunderstanding among architects, that the construction plan should only plan the building. No, it must also take into account that the building "adapts to its use." Washing is part of living.

The airlock was also intentionally designed so that groceries/drink crates or, for example, dirty shoes do not have to be carried across the apartment.

...but it should then take on more (e.g., household-related) functions or be less generously sized.

but since construction is on an existing building, the building authority apparently insists on the construction method.

The building authority must adhere to the development plan. Where there is one, what is stated there applies (or what the overarching state building regulations govern), nothing more. The requirement of §34 for integration cannot be added on top when a development plan already exists.

Do you all only have one car and get by with one bathroom?

I think most builders have only one of two cars, for which a closed garage would be critical for preserving value. If the outer garage were a carport, the visual ratio of car building to human building would be more appropriate, possibly also simplifying thermal aspects.

Ok, then I'm curious to see what the developer calculates. We had already mentioned the 300K€ to him as a rough estimate.

After that, we will sit down with the architect again.

I will report...

EG:

[*]move the door from garage to hallway upwards on the plan opposite the entrance door;
[*]equip the 'airlock' on both sides with cabinets; adjust window accordingly - possibly a bench with shoe storage underneath on one side and next to it; open coat rack etc. possibly leave open.

[*]Shift the wall hallway : airlock + bathroom completely downwards on the plan - design continuous wall of cabinets with only passages to the two rooms.

UG: Laundry room directly at the cellar stairway, office then to the left on the plan.

Cut the 'tip' of the former utility room to the hallway and place cabinets on both sides, or use for freezer & supplies.

Ok, then I am curious what the developer will calculate. We had already given them 300K€ as a preliminary figure.

After that, we will sit down again with the architect.

I will report...

We are building significantly smaller and are already at about +/- 330,000 without a garage plus floor coverings. (Including basement)
