ᐅ Floor plan design, two full stories, approximately 130–140 square meters without a basement

Hello everyone,
We are planning to build a house on a 600 m2 (approximately 6,460 sq ft) plot with a west-facing approach (a dead-end street). Unfortunately, the garage can only be located on the west side (as shown in the picture).

I will soon discuss the preliminary design with the architect. According to the regulations in my country, the original project cannot be changed later on.

According to the zoning plan, we must build an enclosed garage (2 parking spaces per dwelling, with 50% of them in an enclosed garage). This increases our construction costs, so we have to reduce the “ideal” size of 150 m2 (approximately 1,615 sq ft) by about 10-15 m2 (approximately 110-160 sq ft) and, of course, without a basement.

I have read many forums and found that the most important thing is that the living and dining rooms are not narrower than 4 meters (approximately 13 feet) and have at least 35 m2 (approximately 375 sq ft). We will spend 90% of our time there and in the kitchen.

We want an open kitchen facing east with as much natural light as possible (preferably in a two-row layout). We want the utility room to be at least 10 m2 (approximately 108 sq ft), the stairs to be as comfortable as possible without taking up too much space, and a guest toilet without a shower. In front of it, there would be a wardrobe (for an Ikea PAX depth 70 cm (27.5 inches)).

Upstairs, we would like natural light in the hallway, two children's rooms of about 13-14 m2 each (approximately 140-150 sq ft), facing south, and a bedroom facing northeast, where we need to place my wife’s Ikea PAX wardrobe measuring 200x70x240 cm (79x27.5x94 inches). In the bedroom, my wardrobe should also be placed, but it can be smaller than my wife’s.

I would like to build two full floors in a rectangular shape with a gabled roof, similar to Jaydee’s floor plan attached (of similar width and length), although her plan is not two full floors.

My wife would like two bathrooms or a guest WC with a shower. I’m assuring her that one bathroom with two sinks will be enough.

I apologize for my poor German. I have been following your forum for months and have learned a lot. Thank you for any help.

Thank you for the comment. There is no new floor plan yet. That’s why I asked for help here, as I know there are excellent experts. I will then take it to the architect to hand over, and afterwards I will share the floor plan here. The budget is small but should be around 1000 EUR/m² (square meter) in the end (in Croatia, construction costs are about half of those in Germany). Right now, the garage is also an additional expense for us, so we may need to keep the area under 130 m² (square meters). We will only know the final cost once we have the building permit / planning permission.

What do you mean by “half of those”? 1000 EUR in Croatia equals 2000 EUR in Germany? With 2000 EUR in Germany, you won’t get very far. For such flat rates, nowadays you would rather calculate about 3000 EUR in Germany.

Well, 1000 EUR/sqm (1000 EUR/sq ft) is quite optimistic. Recently, prices have been somewhat lower than a year ago. I would like to have a good floor plan and a well-positioned garage on the plot. It will certainly take a few months to obtain a building permit / planning permission, and then we will see how the construction costs turn out.

The problem seems to be that you are very fixated on certain numbers without understanding their significance.
Furthermore, you are contradicting yourself or are unsure about what you actually want to build.
This doesn’t really have to do with the German language, especially considering that

last year you already knew that a fixed (attached) garage had to be built, but you even reduced the area from 130m² (1400 sq ft) to 125m² (1345 sq ft) because of that, even though now 3 children’s bedrooms are planned instead of 2 with 130m² (1400 sq ft).

That was last year:

According to the development plan, we have to build an enclosed garage

Unfortunately, we have definitely learned from the city map that we MUST build a garage (we were told something different before)

That was 3 weeks after the post was created (2 children’s bedrooms):

We spoke with the architect and decided on 3 children’s bedrooms.

Yesterday again for 2 children:

Therefore, we need your help with a simple house of about 130-140 m² (1400-1500 sq ft)

And today:

so we may possibly have to go below 130 m² (1400 sq ft)

What will tomorrow bring? Will you want 3 children again? And then again the “magic” 35m² (375 sq ft) living room and the 3.65-meter (12 ft) kitchen length, which really influence the floor plan?!

The fundamental problem:

You don’t want a simple house!

We want the entrance to be like a space miracle and the utility room on the left side of the floor plan. We also want the kitchen to be 365 cm (12 ft) long and try to place a compact staircase with a landing after the utility room.

The kitchen we saw and would like to include in the floor plan is 3.6 m (12 ft) long,
That kitchen is probably already sold. That was a year ago.

Your wishes need to be gathered and clarified first.

May I do some quick calculations for you?
35m² (375 sq ft) living room
3.65 m (12 ft) kitchen length with counter equals about 9.5m² (102 sq ft)
2m² (22 sq ft) restroom
10m² (108 sq ft) utility room
Staircase with landing about 6m² (65 sq ft) (staircases with landings take up a lot of space)
“Space miracle” hallway 5m² (54 sq ft)
Hallway in front of the stairs about 2m² (22 sq ft)
Possibly a corridor connecting the hallway and stairs 2m² (22 sq ft)
I estimate over 70m² (750 sq ft) just for the ground floor.

I don’t really understand the wish for two stories. Even 2-meter (6 ft 7 in) tall people can live with knee walls about 160-180 cm (5 ft 3 in to 5 ft 11 in) high (like Jaydee). Also, your children will take a long time to reach 2 meters (6 ft 7 in) in height.
You then have a bit more headroom on the ground floor, and if you plan the roof smartly, you get an attic for storage space.

Otherwise, you would probably need to reduce your big living room dream a bit. 35m² (375 sq ft) plus 9.5m² (102 sq ft) kitchen equals almost 45m² (485 sq ft), which is not a small amount when you have to watch the overall house size. It’s generous! For example, the Medleys all have less than 40m² (430 sq ft) but probably function perfectly. And there are other nice kitchens that don’t need 365 cm (12 ft).
For Google Translate: 45 square meters (485 sq ft) is more than a typical house for 4 people needs. It can be smaller if the kitchen is integrated.

A double quarter-turn staircase also works. It only needs about 2.20 x 2.5 m² (7 ft 3 in x 8 ft 2 in).

However, I’m surprised by your statement about downsizing:
prm2021 schrieb:

I had a Medley 126 m² (1356 sq ft) template, but it is 1.5 stories and I had to reduce the ground floor (we would go for 2 full floors).

The Medley 3.0 100 models I see have 65.5m² (705 sq ft) on the ground floor. If you add a second full floor above, you don’t have to reduce the ground floor and end up with 130m² (1400 sq ft).

Thank you for the comment. Last year, we were told that the garage had to be part of the project, but that no one would check whether we actually built it. That turned out not to be true, as we recently found out. The version with three bedrooms was an idea in case we had a third child. Then my wife wanted two bathrooms on the upper floor. Later, she realized that wouldn’t work, so there will definitely be two children’s rooms. I learned here in the forum that it is not worth having living and dining areas under 35 square meters (375 square feet). For two full floors, we were told that the price is the same as for 1.5 stories. I am almost 2 meters (6 feet 7 inches) tall, and with furniture, it would probably be easier.

That is definitely not true! No fixed values are defined here in the forum. I have been following the floor plan discussions here for 8 years! There are no general minimum rules like 35 sqm (375 sq ft) or 4 meters (13 ft) width. I have already seen those fixed values as questionable in another forum where you mentioned them.

That was not the answer to my comment: if you have 65 sqm (700 sq ft) on the ground floor in the two-story Medley, you also have 65 sqm (700 sq ft) on the upper floor… nothing needs to be reduced.
