ᐅ Which of these floor plans can we build upon further?

Hello everyone,

after spending quite some time in another forum, I hope to start fresh here (also for those who might be active in both forums).

We found a plot with a house from a builder. We really like the location (in the far west of the beautiful Ruhr area).

The plot with the standard floor plan (10x9 m, approx. 150 m² (1615 sq ft)) and a 9 m (30 ft) garage fits our budget. We don’t want it any bigger.

There was an appointment back then with the builder and architect where we discussed our wishes and special furniture pieces to be taken along.

We also talked about the 9 m (30 ft) garage. The plan places it on the west side of the house for a straight driveway. However, we realized it might be better on the east side. This way, an additional source of light could be placed on the west side in the kitchen or living room area. On the other hand, due to the neighboring house to the west, this would likely be a passive light source. Would a window on the east side be as effective as on the west side? On the west side, the house is 6 m (20 ft) away, and its garage is 3 m (10 ft) away. On the east side, the window would be approximately at the terrace level of house number 11.

Since the driveway to the garage on the east side seemed quite narrow, we simulated it with our Fabia station wagon (4.25 m (14 ft) long) along a house edge and the plot boundary marked with chalk. The driveway and exit worked, even if the neighbor would build a fence right on the boundary. But we aren’t yet 100% convinced about this option.

Originally, we planned to build smaller than the offered standard floor plan (10x9 m), wanting 10x8 m (approx. 86 sq m / 920 sq ft). The architect drew something for this, but we didn’t like it at all.

Then we went for 10x8.5 m (approx. 91 sq m / 980 sq ft), with the architect basing it on the standard floor plan but with 15 steps instead of 14. The straight or quarter-turn staircase caused repeated problems during several redrawings. Mostly, the dining area was too tight and/or the hallway or entrance area too large.

At one point, we briefly sketched another floor plan ourselves (the quarter-turn staircase rotated by 90°) and had it redrawn, but we rejected it again due to what felt like too small a TV area (4.15 m (13.6 ft) depth). I should mention that in our previous homes, we always had a distance of 4.5–6 m (15 to 20 ft) for a 42-inch TV and found that comfortable.

We were nearly desperate and looked at show homes. We got some great ideas there (e.g., built-in wardrobe in the entrance hall, children’s rooms around 14–15 m² (150–160 sq ft) are sufficient) and saw living rooms with TV areas around 3.5–3.75 m (11.5–12 ft) deep and tried them out. We didn’t find them too small, especially considering the manufacturer recommendations for optimal TV viewing distance.

Hoping that a larger floor plan would solve all problems, we decided to go for 10x9 m (150 sq m/1615 sq ft) size and saw the Signus floor plan (with 14 steps) from Kern-Haus and had it redrawn accordingly (with 15 steps). In retrospect, the basic structure is similar to the builder’s standard floor plan, except the staircase and TV area were handled differently. The dining area remains tight, and there is an extra barely usable space between the entrance and dining area.

At some point, the architect drew the standard floor plan with a corner staircase. We asked him to redraw it with dimensions but we are still waiting for this version today. Instead, we recently received the Signus floor plan with a slightly modified quarter-turn staircase (one step from the straight section was moved to the landing).

Here are the key data first:

Development plan/restrictions
  • Our plot and house will be number 10.
  • Plot size: 370–380 m² (16 m (52.5 ft) wide, approx. 23.8 m (78 ft) deep), no slope.
  • Building envelope: 10 m (33 ft) wide and 13.5 m (44 ft) deep, with a 3 m (10 ft) setback from neighbors and the private road (which will be extended to the boundary of number 11).
  • Orientation: south to southeast.
  • Floor area ratio (FAR): 0.4
  • Total floor area ratio: 0.8
  • 2 full stories
  • 6° flat roof design
  • Bauhaus style
  • Parking: Within the development area, private demand for garages, carports, and parking spaces must be met within the plot itself due to limited access areas. Garages, carports, and parking spaces should not be distributed randomly on the plots. They are only allowed inside the building zones and designated parking areas to avoid a disorganized impression and to prevent the use of rear zones and setback areas next to the existing buildings for garages, carports, or parking spaces.

Homeowners’ requirements
  • Detached
  • No basement
  • 2 full stories
  • 2 adults (35, 40), 2 children (6)
  • Kitchen, living/dining room, WC, bathroom, utility room, master bedroom, 2 children’s rooms, 1 office (exclusively for home office), additional storage room
    • In the kitchen, it would be nice to have a view of the garden from the main workspace or sink.
    • In the living room, it would be nice to see the garden from the sofa.
    • The area between living room and entrance/hall/staircase should be closed off with a door if possible.
    • In the master bedroom, the door should be visible from the bed, and there should be no window behind or above the bed.
    • Children’s rooms approx. 15 m² (160 sq ft) each, both facing south (better view, more light) with appropriate windows.
    • The office should be at least 8 m² (86 sq ft). This room does not necessarily need access from the hallway, it could be an adjacent room. The desk should be placed sideways to the window. Also, it should be arranged so that the desk is not directly visible from the street (reason: I find it uncomfortable to sit with my back to “the public”). The room should be designed to also hold a 1.5 m (5 ft) wide wardrobe (storage) and one or more 1 m (3.3 ft) wide highboards (ideally three).
    • A window in the upstairs hallway would be nice.
  • No overnight guests planned so far
  • Rather closed architecture
  • Prefer modern design
  • Prefer a closed kitchen, but a semi-open kitchen is also possible
  • 5-6 dining seats
  • No fireplace
  • TV wall with 5.1 sound system
  • 2 parking spaces (1x 9 m (30 ft) garage), garage on the east side?
  • Utility garden
  • No direct access from garage to utility room

If you had to give up on details/features
  • We can and want to do without a shower in the guest WC.
  • The 9 m (30 ft) garage on the east side is probably best in terms of light, but placement on the west side is also possible. A 6 m (20 ft) garage with an annex (for garden furniture, lawn mower, bicycles, etc.) elsewhere is also conceivable. However, since it makes sense to have an additional parking space in front of the garage, a 6 m garage combined with a 5.0–6 m parking space would practically end at the back of the house, so we wouldn’t really gain anything.

Builder’s floor plan (images ending with 295772-295772-5.png)
House design – why did the design turn out as it is?

  • The builder’s architect based the floor plan on the Signus by Kern-Haus.
  • We like the basic structure so far.
  • The front entrance with the door and the windows above feels much more inviting than the standard floor plan.
  • Is the front door drawn too large?
  • The door to the living room is not ideal. Depending on kitchen layout, it would be in the way when open.
  • Would a window sill height of 1.01 m (3.3 ft) be sufficient for the kitchen window? The left window in the dining area facing the terrace could perhaps be made floor-to-ceiling. It might not look perfectly symmetrical from the outside, but it would look the same from the inside in the dining area.
  • Due to the quarter-turn staircase with one step on the exit, the entrance hall area was reduced at the expense of the TV area. Is the TV area still large enough?
  • The entrance hall is quite large because of the quarter-turn staircase with the step on the exit. How could this space, especially under the stairs, be better used? Maybe with a built-in closet or storage room (with its own access)? We also once thought about rotating the staircase 180° and using the area under the stairs at the entrance as a wardrobe (built-in closet). But then what about the door to the living room? And how would it look when entering the house and seeing a cupboard right away? On the other hand, it might make sense to swap the front door with the window element.
  • The utility room has a 73.5 cm (29 in) door. Is that sufficient or would an 85 cm (33.5 in) door be better?
  • For the WC, we might prefer the door to open inward and swap the toilet and washbasin.
  • The two bed niches in the children’s rooms don’t look optimal at first glance. On one hand, only a wider bed fits here, and the other child would have to place a bigger bed elsewhere later (unless sleeping partially under the window). On the other hand, from this niche, you can’t see who enters the room. Maybe this deep niche is better for the entrance and perhaps a wardrobe with a headboard? Or the partition wall could be shifted a bit left (centered between the two windows), so that beds fit properly in both niches and bigger beds would protrude a little.
  • The storage room could perhaps be a bit narrower in favor of the bathroom. Maybe it would look better with an 85 cm (33.5 in) door here as well?
  • The heating system will likely be underfloor heating with a gas condensing boiler and solar storage for hot water support.

Own Floor Plan 1 [U](images ending with 295772-6-295772-7.png)
House design – why did the design turn out as it is?[/U]
  • DIY… since we can’t let go of the basic structure from the builder and Signus, I also drew a bit. Access to the utility room was moved to the kitchen and a 1.25 m (4 ft) wide built-in closet wardrobe was planned in the hallway.
  • Maybe the stairs should be moved a bit further left to get a larger living/dining area. This would allow making the WC narrower and possibly longer.
  • The square dining/living room looks like it might not be used optimally later. The distance between TV and sofa is quite large at 5.87 m (19 ft).
  • The upstairs hallway might be a bit too wide (due to the storage room). The wall between the storage room and the left children’s room could be moved left a bit. This would mean the door to the children’s room is not aligned with the stair railing but set a bit behind the wall at the stair’s end. Or could this be solved by adding a railing to the last step facing the left children’s room (similar to the builder’s floor plan)? On the other hand, such a wide hallway offers space for 30–40 cm (12–16 in) slim sideboards.
  • The layout of WC and bathroom might be done differently.
  • Windows and doors are not fixed yet and could be better positioned.
  • We like the entrance area better with the two outer windows above.

Own Floor Plan 2 [U](images ending with 295772-8-295772-9.png)
House design – why did the design turn out as it is?[/U]
  • DIY… We reviewed all floor plans again and came across the one with the staircase rotated 90°. I extended this plan to 9 m (30 ft) depth and shifted the stairs.
  • I find this layout very flexible since the central axis can be moved depending on needs. The same applies vertically for the utility room and office.
  • I like that with the stair positioning upstairs you come out behind the central axis, allowing large straight rooms to the south as well as to the other side.
  • I thought about using another staircase but couldn’t find a good location, and it would mean no window in the upper hallway.
  • The kitchen could also be open, or alternatively as our preferred closed kitchen. The dimensions shouldn’t feel too narrow.
  • The entrance area might be a bit large, especially in front of the WC. But it could fit a slim sideboard, mirror, or day coat rack.
  • The children’s rooms might be a bit too large. The central axis including stairs could be moved about 20 cm (8 in) toward the garden, but that would narrow the dining/living and cooking area.
  • The master bedroom might be a bit narrow if the bed is placed on the right and a sideboard with TV on the opposite wall.
  • Whether the stair overhang is enough to access the bathroom from there still needs to be checked in detail.
  • The layout of WC and bathroom might be done differently.
  • Windows and doors are not fixed yet and could be better positioned.
  • We like the entrance area better with the two outer windows above. Whether to place two slim windows beside the front door or one larger window and then likely none on the top line needs further review.

What is the most important/basic question about the floor plan summarized in 130 characters?
A few more characters than 130.
  • Is one of the floor plans good enough to build upon?
  • Where would you position the garage?
  • How would you position the TV area? The TV wall (creating about 1.8–2 m (6–7 ft) longer wall surface) on the south side with a view from the sofa into the garden? Or the TV wall inside the house?
  • Both children’s rooms facing south (view of greenery) or rather west side (view of neighbor’s house)?

So, that was a lot of text.

I hope I haven’t forgotten anything and wish us a pleasant discussion.

P.S.
We also got the suggestion to build the house narrower (7–8 m (23–26 ft) wide) and deeper instead of 10 m (33 ft) wide. This way, the garage could be on the west side and an additional light source could be positioned on the west side in the kitchen or living room area. Somehow, we have not found a fitting floor plan idea yet that makes us rethink this. Also, the idea of having a very long green strip on the east side complicates it in our minds.

Site plan:


Ground floor plan: Living/Dining, Kitchen, Guest/Office, Hall, Utility room, WC, Terrace, Garage.


Upper floor plan: Master bedroom, Child 1 and Child 2 bedrooms, Bathroom, Hall, Storage room, Staircase.

Some aspects are not included but are also not straightforward. For example, the number of windows versus usable space. Everyone says you should let light into the house. At the same time, each window limits the possibility of placing a taller cabinet.

Another example is the placement of the TV. As a basic guideline, we received two examples for a living room layout from the architect.

Okay, here’s a new tip for you: scoring method, also known as utility analysis. No joke—I want you to take this seriously and approach the matter methodically and in a structured way!

1. --> Choose the 20 most important criteria for a floor plan and assign each criterion a weight from 1 to 10 (10 being most important, 1 least important):

Example:

TV placement – Weight: 7
Number of windows – Weight: 9
Storage room – Weight: 3
Criterion 4 – Weight x
Criterion 5 – Weight x
and so on...

2. --> Then take ALL the floor plans you currently have and score each one against the 20 criteria on a scale from 1 to 10 (10 means you like it best, 1 the least):

Example:

Floor plan A:
TV placement – Score: 5
Number of windows – Score: 9
Storage room – Score: 4
...and so on

Floor plan B:
TV placement – Score: 3
Number of windows – Score: 2
Storage room – Score: 10
...and so on

3. --> Now calculate a utility value for each floor plan by multiplying the assigned weight by the score for each criterion and summing the results:

Example:

Floor plan A:
TV placement = 7 x 5 = 35
Number of windows = 9 x 9 = 81
Storage room = 3 x 4 = 12
...and so on
Utility A = Total = 35 + 81 + 12 + … = …

Floor plan B:
TV placement = 7 x 3 = 21
Number of windows = 9 x 2 = 18
Storage room = 3 x 10 = 30
...and so on
Utility B = Total = 21 + 18 + 30 + … = …

4. --> The floor plan with the highest total utility score represents the best compromise for your requirements, combining consistent weighting with individualized evaluation. In my brief example with just three criteria, A = 128 and B = 69, meaning option A is clearly better than B.

Regarding the weighting, agree with your partner on the same weights, but each of you score independently. This way, you get different utility values and gain insight into each other’s perspective on the various floor plans. If this still doesn’t help, there’s another method... I have more ideas lined up. In the end, we’ll program a non-linear model that optimizes room by room.^^

Point evaluation method aka utility analysis

This method is suitable when the requirements are clear. From my perspective, however, there is still a deficit here that needs to be addressed first.
StanSch schrieb:

- For the kitchen, it would be nice to have a view of the garden from the main workspace or sink.
- For the living room, it would be nice to see the garden from the couch.

Does "nice" mean mandatory or optional? If mandatory, do both need to have the view, or can you do without one? Do you spend more time looking at the garden from the couch or rather watching TV? Does the dining table also need to face the garden?
StanSch schrieb:

The area between the living room and hallway/stairs should be closed off by a door if possible.

Is this about noise, separation from the entrance, drafts, etc.? Maybe there are more suitable solutions?
StanSch schrieb:

A window in the upstairs hallway would be nice.

And what if the floor plan turns out really great but this is not fulfilled? A perfect example of why a scoring system (see above) is necessary as a second step.

With that we have made a decision!

Please answer this question thoroughly and without referring back to the original post.
For example, I don’t see any of this in the initial post. Also, what motivated you to draw your own floor plans? But especially, what improvements did you make in your own plans compared to the BT floor plan?
You deliberately chose the 10x9 meter (33x30 feet) option, okay. What exactly causes you to doubt this? Or is @11ant perhaps not so wrong, and the biggest doubt comes from the frustration that not all wishes can be accommodated 100% in the 10x9 layout?

I’m starting to wonder why it’s harder to list these few points than to share new floor plans.

Thanks for this approach .
Mottenhausen schrieb:
then you take ALL floor plans

That raises the question: which ALL?
All from the architect, since these are more thought-out than the self-drawn ones?
Also the 8.5-meter (28 feet) deep floor plans? We considered that size for quite a while and then thought that 9-meter (30 feet) depth would be easier.
We actually only have the 9-meter (30 feet) deep floor plans from the first post, in two different staircase variants.
Then there is the one from the brochure, which, however, does not meet the requirement for the south-facing children's rooms.
And then the one from yesterday. That one is interesting too, but not yet fully developed.

Does "nice" mean must or could? If must, then both, or where can you compromise? Do you spend more time looking from the couch toward the garden or rather toward the TV? Does the dining table also need to face the garden?

That’s exactly our problem.
Basically, we are flexible. We certainly have wishes but understand that not all of them can be fulfilled at once. So it comes down to the overall package.
We have always wanted the kitchen to face the garden. A kitchen at the front facing the street also has its advantages (short way to bring groceries inside, children don’t have to constantly walk through the living room to get something from the kitchen).
The couch is mainly used for watching TV.

Yes, it’s about noise, drafts, and indirectly about heating.
Slava_S schrieb:
Also, what motivated you to draw your own floor plans?

The idea was to avoid asking the architect for a new floor plan every time and instead to provide a basic concept. I’m not good at finalizing the drawings because I don’t know the exact dimensions a staircase will have, etc.

You don’t need to build airtight because of heating. You can’t compare houses built to the energy-saving regulations with older houses. Your stairwell, if unheated, will never get as cold as it used to.

You know ours. It’s open and a passive house.

As for noise, that is very individual. Some build galleries, others have a separate stairwell.
