Hello,

I came across this interesting forum yesterday and would like to take the opportunity to present my first floor plan draft here in the hope of receiving valuable advice. Often, being too focused on one direction limits ideas, so fresh eyes and new inspiration from others are always very helpful.

The general idea is to have the house built completely turnkey by a prefab house company, without any DIY efforts on our part. So far, no architect has been hired because I first wanted to try putting my own wishes and ideas on paper. I believe that with this DIY preliminary planning, there might be a better basis to go directly to an architect or even several prefab home providers to obtain feasible implementations and corresponding cost estimates.

I look forward to your feedback (and I’m already bracing myself...).

Development Plan / Restrictions

Currently, paragraph 34 applies. However, a design guideline is expected next year. The house has already been initially designed within the preliminary framework of this guideline.

The plot size is about 650 m² (7000 sq ft). It is a flat lot on a road with through traffic. Floor area ratio is 1.5. A detached garage will be attached to an existing building with two full floors plus an attic conversion on the right side, and next to the garage will be the new house.

The existing building is oriented with the eaves side to the street. The new house is planned to be positioned with the gable end facing the street.

The neighboring house on the other side (directly on the street) also has its gable end facing the street. Parking spaces: 2 (in front of the garage) plus a double garage (6 x 9 m (20 x 30 ft)). Number of floors: 1.5. Roof type: pitched roof, 25 to max 35 degrees. Style: conventional. Orientation: northeast to southwest.

Maximum heights/limits

The planned maximum height is about 8.5 m (28 ft).

The house must be set back 3 m (10 ft) from the front property line. The double garage should/setback 5 m (16 ft) from the front property line (unfortunately, no more was allowed in the planning approval inquiry, so from my view, only a front entrance to the house is currently feasible).

A direct connection from the double garage to the house is desired.

A corresponding positively approved preliminary building permit is available.

Homeowners’ Requirements

We want a modern house with a pitched roof.

A basement (possibly a partial basement) is desired and unfortunately required due to space constraints (not for living purposes; the basement should only serve as storage or a hobby/craft room).

For the knee wall height of the 1.5-story building, we envision 1.60 to 1.80 m (5’3” to 6’0”).

Number of occupants: 2 persons, 60 years old.

The house should be designed to be barrier-free as much as possible and should allow living only on the ground floor at an advanced age.

The total required area on the ground floor and upper floor should be around 180 m² (1937 sq ft).

The office will be used privately only.

We expect about 5 guest stays per year.

The living/dining area should be spacious and as open as possible.

A storage room between the double garage and the house (which also allows access from the garage to the house) is required.

The kitchen should be open with a cooking island or peninsula.

A central fireplace in the living/dining area is planned/desired.

A balcony with access from the gallery and the office is also desired. Alternatively, a loggia (either one-sided or spanning the width of the house) could be considered.

It is important for us to have an open gallery over the dining area where you can stay and where fitness equipment will also be placed.

The double garage measuring 6 x 9 m (20 x 30 ft) is fixed, as several vehicles need to be accommodated.

House Design

A first preliminary plan created using a 3D program is available.

What I like about the initial plan are the open sight lines, the gallery, and the large living/dining area facing the garden (southwest).

I especially struggled with the staircase design. Initially, I wanted a straight staircase with access from the living/dining area, but I discarded this for various reasons (also because a cellar staircase is still needed “underneath,” which makes a straight staircase less visually appealing).

After initially planning bathroom access from the sleeping area (which also leads to the dressing room), I eventually decided for an access from the hallway to allow a wider shower, a large double washbasin in front of the window, and a toilet with at least 90 cm (35 inches) clearance to the side.

What I don’t like yet is the gable side area between the open space and the office with the 90-degree angle.

In the (probably too) narrow utility room, the washing machine and dryer are to be accommodated.

Why did the design turn out this way?

For example, only about 18 m (59 ft) of plot width is available, which limits the house width to a maximum of 9 m (30 ft) with a set double garage width of 6 m (20 ft).

But remember to allow enough room for movement.
Here’s a rather bold idea concerning the view of the plank wall when entering the house. I hardly dare to say it out loud.
Could you design a freestanding steel staircase that isn’t embedded into the side wall, and then replace the front "plank wall" with a glass railing? This would provide a view of the "bold staircase structure" looking down to the basement stairs and up to the stairs leading to the upper floor.

It is always very important to understand the individual “quirks” (in a positive sense, of course) of the people involved to create a good floor plan; I really like when someone plans something special for themselves or their partner. We know a couple where he loves listening to loud music but would never wear headphones (3-room condominium), and they are still married... phew. I usually wear my cozy slippers in the gallery when I watch documentaries. If that’s not suitable for someone, they’ll either need doors or soon the contact details of a lawyer.
@ypg That makes sense to me regarding the hallway/corridor, so I also think this curve is only planned because a “nonsensical curve” was already built before. There are elegant floor plans, even for these spoiled “best agers.”
The staircase also seems somewhat out of place to me, but I can’t come up with an alternative idea.

The extra room upstairs is needed to set up a few display cabinets for items that cannot tolerate much light over time. My/our hobby is vintage cars and old racing bikes. The “sports gallery” seems somewhat (outrageously) large on the floor plan, although I would like the idea of working on bikes there (which I won’t tell my wife, though).

The topic of collecting has already been discussed :-)
A friend of mine always had his two polished Harleys standing in the living room and was happy with it.
I would never consider anything I am currently passionate about as “outrageous”; dragging my whole life behind me wouldn’t even cross my mind, and apart from a beginner’s swimming badge and a certificate for winning youth sports competitions, I wouldn’t have anything to display anyway; luckily, I have been rather unsuccessful.

Very quickly, you’ll get a letter from the lawyer, but luckily, there is also a garage.
Okay, there are other birds besides me, but that is definitely a special idea—to have the smell of grease in the air instead of lavender scent if you like it; I’d much prefer a neat, single-level extension or a spacious garden shed where you can even watch dusty old videotapes with Danish westerns with the neighbor.
At least does your wife know that you are planning a house? What does she think about the details she knows so far?

Yes, so far she has liked all my ideas (even the ones I now realize were not so good). She always gives me tips on where to place flower pots... The most important thing for her is the walk-in closets. Unlike me, she also has a photographic memory for details and solutions she has seen during visits to prefabricated house showrooms.

By the way, I’d appreciate alternative ideas for stairs if you don’t like "mine."

Then it fits perfectly, that’s what really matters; by the way, I find the walk-in closets quite small, maybe you could pass that on :-). The staircase was a tough, frustrating issue for us, but in the end, it turned out great; check out the “Zeitform” section, especially the cantilevered staircase. It’s a very friendly one-person business that might have the right idea for you or can at least tell you what’s feasible.

Well, I’m currently juggling and playing Tetris with walls and have now stepped back.
However, I’m also somewhat half-hearted about it: on one hand, it’s about optimizing for the biker; on the other hand, I initially said this plan contains biker-related mistakes that I cannot support.
I have also never understood, as a mature adult, not using the main entrance and why you always want to disappear through the garage into a utility room that has nothing to do with the entrance and usually just has laundry on the floor.

Well, as soon as she lives there, she’ll realize the garage is not as magical as the gallery room.
I remind you that this room will (hopefully) be flooded with daylight and therefore naturally a bit warmer than elsewhere, where there is only a roof window. Maybe this is not the right place for bike training?!

And what is the basement supposed to be for now?

A lot is possible. With this idea, I wonder why everything else is supposed to be so closed off, but suddenly a basement staircase should bring transparency. A steel staircase has many disadvantages—noise, vibrations, coldness. It looks good if you look at it nicely. A glass wall takes up floor space. Or what exactly do you mean by a steel staircase?

Yes, most of them are indeed either narrow or small. Usually, that’s intentional. I also don’t see most of them as age-appropriate. There simply isn’t enough space for that.

Here are my two variants (with different furnishing; I didn’t save the small furniture):

I haven’t reread everything, but having a house entrance on the eaves side would probably solve most of the layout problems; at least it would eliminate the long corridor. Is that really not possible?
