House Design
Designer: planner from a construction company
What do you especially like? Why? Mostly drawn according to our wishes
What don’t you like? Why? Dining area too narrow between kitchen and living room (the left kitchen unit must be this long (from left to right: raised dishwasher, oven and microwave stacked, door to pantry, side-by-side refrigerator, tall cabinet). On the right side, we are considering shortening it a bit to gain more space in the dining area.
Estimated cost according to architect/planner: €400,000
Personal budget limit for the house including fittings: €410,000
Preferred heating system: air-to-water heat pump with underfloor heating

If you have to give up something, which details/expansions
- can you give up: open
- can’t you give up: open

Why is the design as it is now?
We spent a long time drawing, changing, and adapting ourselves. This is the result of collaboration between the planner and our wishes.
Which wishes were implemented by the architect? All

Information:
The house will be a single-family home built in solid construction, KFW55 standard, with photovoltaic system, underfloor heating, air-to-water heat pump, gable roof with a 22° pitch. The family planning is complete with 2 adults and 1 toddler. The house is built on a sloped hillside plot with a 10% gradient, accessed from the street. The basement parts fully covered by earth are made of waterproof concrete, the rest is masonry. The south side faces the street and thus has the main terrace. The passage between kitchen and pantry is hidden behind a concealed door in the kitchen wall unit. From the entrance area to the pantry, access is either via a sliding door or a regular door opening towards the pantry. A lifting system for the lower bathroom is not required since the slope from bathroom to sewer will be 2.8%. The sewer connection on our property is located at a depth of 3.39 meters (11 ft). The house will also be built slightly higher than the street level. A backflow valve is, of course, planned. From the lower bathroom, there is another door leading into the rear garden (north/east). Instead of a deeper foundation due to the slope, the double garage (prefabricated garage) will have a transverse utility garage with a side door, 3 x 7 m (10 x 23 ft), so it can be used as storage / cellar / garden equipment space. The terrace will not extend as much around the corner as in the plan, allowing the ground to slope down more quickly there.

After so much planning, thinking, and revising, it is easy to become blind to details and overlook some things. Therefore, we appreciate any criticism, tips, tricks, and suggestions

Fire away & thank you very much in advance.

My expressions are definitely sharper than my pencil – some people get a bit offended (which is not my intention)

I much prefer being straightforward than forcing a smile, sweet-talking, and then making a face behind someone’s back. I can handle this kind of approach well. Our "problem" is that we simply can’t afford a specially designed, custom house that’s different from the "standard" because that would add significantly to the extra costs, and due to the sloping site, the landscaping will cost more than we want anyway. So, we are trying to make the best of what is available to us.

Plan a path around the house for wheelbarrow, hand truck, lawn mower, and similar equipment. Also, reconsider a direct access from the hallway to the garden. In the basement, you have large rooms where you could allocate some space for this.

It is possible to go all the way around the house on both the left and right sides. The detailed landscaping plan is not finished yet. We will have a staircase located behind the passage between the double garage and the house. This staircase will run down alongside the rear wall of the double garage.

On the right side of the house, the terrace will not wrap around as much and will be only about 1 meter (3 feet) wider than the house on that side. This leaves an additional 4 meters (13 feet) where the ground slopes naturally, allowing easy access at any time from the south-facing terrace on the main floor down to the north-facing terrace in the basement.

A sink in the utility room, to the left of the washing machine and dryer, is already planned.

Yes, the bathroom is huge, and our little son doesn’t even notice if it’s “only” 18m² (195 sq ft) instead of 20m² (215 sq ft) or so.

Since the basement level will actually be used about 99% only by us, we wanted to avoid a "corridor" just to have an extra door. It was more important to us that our son has a very large room available.

And I would swap the dressing room and bedroom...

Unfortunately, that’s not possible for the following reason. Since part of this room is being constructed with waterproof concrete because it is still fully underground, there is only the one large window shown in the plan. You can see on the floor plan where the waterproof concrete basement wall ends (exactly at the partition to the dressing room). We might add a light well window in the dressing room. If we swapped the dressing room and bedroom now, the bedroom would have no window and would be located within the waterproof concrete, which we don’t find very appealing.

Normally, that would make more sense. But here, the bedroom wouldn't have a window because it’s built into the slope. I would probably skip the extra hallway since you can walk all around the house on both sides. But in any case, I would plan a patio door for our son’s room.

Exactly right, you can walk completely around the house. On the left, behind the passage between the garage and the house, there will be a staircase, and on the right, there’s about 4 meters (13 feet) to the neighboring property, where the land is graded so you can walk down normally.

The large window on the north side in our son’s room is already a floor-to-ceiling window with a (door). We’ve been debating whether to keep it that way or not. Why the hesitation? The floor-to-ceiling window takes up quite a wide area, which limits options for rearranging the desk, bed, etc. You just can’t use the space in front of that window properly. That’s why we thought about replacing it with a door to the bathroom—after all, you don’t place furniture in front of a bathroom door, and we wouldn’t want to move the bathtub or shower anyway.

I’ll swap the staircase later tonight and take a look at the guest toilet and so on—that’s a good idea. Let’s see if we like it. THANK YOU

The bedroom layout suggested by @Tamstar is more practical and attractive if you leave out the small wardrobe unit. You would then still have over 4m (13 feet) of wardrobe space available, plus a nice, large bedroom. You could also place a dresser island in the middle for additional storage and surface area.

That’s exactly what we discussed last night—making full use of the wardrobe length to reach 4 meters (13 feet), moving the partition wall further back toward the bedroom, and thus gaining more space between the bed and the wall next to the children’s room.

I’ll update my plan tonight with all the ideas you’ve shared and then post it.
