After subtracting the garage and house, only 87.60 m² (943 ft²) remain for terraces, pathways, garden shed, courtyard/driveway … that’s getting tight.

Wow, look at that – if it’s God’s will. Coincidentally, the whole forum is about 86 m² (925 ft²).

Floor plan: living/dining area with sofa, dining table, kitchen, laundry room, basement/technical room, terrace.

Okay, just kidding. The architect’s recommendation always sounds promising. I hope we’ll get to take another look.

Edit: Just don’t bring any plans or sketches! Simply submit your wishlist without suggesting any solutions. Cross out everything on the list that is optional – especially the positioning of the house, garage, and rooms. Just let it be done. If they make any proposals, you can always say yes or no.

Okay, just a little joke. An architect’s recommendation always sounds promising. Hopefully, we’ll be allowed to take another look.

Very funny.

Of course, you’re welcome to look once I have something new.

The new planner will only receive the publicly available documents and a bullet-point summary without reference to the garage location. I’m curious to see what comes out of it.

I’ve slept on it again, and relocating the living, dining, and kitchen area to the basement doesn’t really convince me. Even if it may seem conservative, for me the front door, terrace, living, kitchen, and dining areas simply belong on one level or elevation. It’s clear that compromises must be made with a south-facing sloped lot. Where there’s slope, there is also shade.

Regardless of the new floor plan from the planner, I have revisited the existing drafts (in case the shape and arrangement of the stairs and front door remain, which doesn’t mean they have to).

Before criticism starts again, it would be nice if you try to evaluate this based on the factors that are important and repeatedly mentioned by the homeowner, not just personal preferences.

It might also be possible to swap the child’s room and the office.

Ground floor plan: kitchen, dining, living, hallway, shower/WC, terrace, optional pool.

What is that phallic symbol in the kitchen? *clears throat

Yes, you can’t leave the “peninsula” in the kitchen as it is. You can’t access the sharp corner. But the kitchen department will plan that for you.

The wellness area in the basement is unfortunately very tight. Relaxing there will be difficult.
The toilet in the upstairs bathroom is below the 2m (6 ft 7 in) height line. That needs to be changed.

I like the idea of having a pool on the ground floor terrace. However, I find it hard or nearly impossible to imagine how that would be implemented. How deep is it intended to be recessed into the ground, or is it supposed to be more like a freestanding tub?

Since the layout otherwise doesn’t differ much from the original plan, there will probably be few new opinions on the design. Let’s hope for the new architect.

That is not a phallic symbol, but a simplified top view of the existing kitchen. (see attached photo)

I like the idea of having the pool on the terrace on the ground floor. However, I find it hard to imagine how it will be realized. How deep will it be embedded in the ground, or is it more like a tub to be placed there?

Since the layout is otherwise very similar to the original plan, there likely won’t be many new opinions on the design. Let’s hope for the new architect.

You can get into the sharp corner, it’s probably due to my poor drawing skills. But since it is an existing kitchen and the room dimensions are (almost) identical, I know it will fit.

The bathroom arrangement still needs revision anyway. I just sketched it roughly as I imagine it could be.

The pool is planned to be optionally recessed into the ground at basement level (not ground floor), so that the pool edge is at the finished floor level of the basement.

That’s why the idea is to place the wellness/fitness area in the basement, to have direct access to the outdoor pool from there. But that will be addressed later in the landscaping phase.

I noticed the tightness of the wellness area as well, but it is really intended purely as a relaxation room, since the fitness area has been moved upstairs. We would need to review the exact sizes of the whirlpool and sauna to see if it still fits. But previously, the wellness area was considered too large and nobody thought it was needed at all. Now that I’ve halved the space and its intended use, the criticism is that it’s too small... it’s difficult to please everyone.

Modern kitchen with island, dining table, chairs, white cabinets and oven.
