Hello everyone,

I have been reading here for a while, and now it’s time for us to start planning the floor plan. We had our first appointment with the architect this week and have already shared our ideas with him as preparation. We received a first draft, which we will discuss during our meeting. Additionally, we created some rough sketches ourselves (without considering structural issues, windows, the staircase is drawn way too small, etc. – really just very basic to clarify our ideas, I’m attaching those as well).

Development plan / restrictions
Plot size:
635 sqm (6,840 sq ft)
House size: 135 sqm (1,450 sq ft)
Number of floors: 1.5
Roof type: Gable roof
Maximum heights / limits: Knee wall 1.20 m (4 ft)
(We would have preferred a bungalow or a townhouse, but unfortunately, there are no plots available here. We are happy to have found one at all, even if that means we have to accept 1.5 floors and a knee wall.)

Client requirements
Basement, floors:
no basement
Number of occupants, age: 2 persons, 39 years old (children are 90% unlikely to be planned)
Office: Home office about once a week – although I usually work from the living room with my laptop
Guest stays: maybe 2 to 3 times a year, so far managed without a guest room in the apartment
Architecture: open plan
Construction style: modern
Kitchen: an island kitchen probably won’t fit, but it should be an open kitchen, possibly with a breakfast bar
Dining seats: 4 to 6 – for occasional visitors – but that could also work by putting in a dining table as needed and otherwise using a kitchen breakfast bar daily
Fireplace: rather no, due to cost and space reasons
Balcony, roof terrace: terrace
Garage, carport: carport

Desired ground floor layout:
Includes utility room, guest WC, hallway, living area (consisting of living room, kitchen, dining area/other)

Entrance and ancillary rooms:
- small hallway with space for a coat rack
- utility room about 8 sqm (86 sq ft), space for technical equipment, washing machine, dog food & co.
- guest WC max. 3 sqm (32 sq ft); no guest shower needed

Living area:
- quick access from the entrance to the living area, ideally directly to the kitchen
- living/kitchen/dining area as large as possible (ideally approx. 50 sqm (540 sq ft)), minimizing space wasted by other areas/rooms on the ground floor
- kitchen possibly with island/breakfast bar if space allows
- book corner with window seat if space allows (for info: I have about 1,000 books and a piano – these need to be accommodated somewhere)
- space-saving staircase, preferably open/integrated in the living area to save hallway space

Desired upper floor layout:
Includes bathroom, bedroom, dressing room, hobby room, another room (possibly office, guest room)

Bathroom:
- bathroom with walk-in shower + bathtub (freestanding = nice to have)
- possible wall separation for the toilet (if it fits)

Sleeping area and dressing room:
- bedroom with walk-in closet/dressing room, if feasible given house size
- access from bedroom to dressing room and bathroom

Additional rooms:
- hobby room with space for desk, crafting corner, small seating area
- another room as office/sports/guest room or possibly a child’s room after all – alternatively, a larger hallway/gallery with seating area and light well to the floor below

What don’t we like? Why?
  • Narrow galley kitchen. I already have this in my apartment and don’t want it anymore. Is it really not possible to do it differently? Structural or other reasons?
  • Staircase located in the dirty area. Shoes, dirt, etc. I don’t want to walk through that every time I go upstairs.
  • Dressing room under a sloped ceiling. Not much space left for wardrobes...
  • Office only 7 sqm (75 sq ft). Does that make sense? If, against expectations, a child arrives, this would be the hobby room, which would then be much too small.
  • Bathrooms. Does the layout make sense? I always thought they should be arranged above/below each other.
  • Technical equipment. Could it also be located in the attic?

Cost estimate according to architect/planner: $240,000 – that is also the financial plan (excluding kitchen or additional furniture, plot and landscaping – total budget is about $400,000)
Preferred heating technology: air-source heat pump

If you had to give up something, which features/finishes could you do without? very reluctantly the dressing/walk-in closet

What is the most important fundamental question about the floor plan, summarized in 130 characters?
How should we best proceed with the draft? Are there ideas that could help us align better with our wishes for the discussion? Which ideas should we discard?

A few more remarks: Reading other posts here sometimes makes me feel guilty because we are “only” building 135 sqm and everything seems so “small.” Still, I want to get the best possible value for my money. Financially, this size is the most reasonable for now.

(PS: And in case the question arises: Why are children only 90% excluded? There are many reasons – for example, difficulties conceiving, but not completely giving up hope.)

Thank you in advance for your opinions.

Those who build with bricks shouldn’t talk about sheet metal. This roughly applies to standard square meters as well, but they should move away from their carpet-area mindset because only one of the two calculation approaches can be correct at the same time.

I have been here for two years and don’t care about those star ratings, precisely because, in my opinion, they are a sum of many unnoticed or misclicked ones.
You wanted a bungalow, so build a bungalow.
He can pay for the mixed calculation!

I don’t quite follow— which “two” calculation approaches are you referring to?

Additional info: the calculations are based on DIN 277. And looking at the attached sketch (source Wikipedia), the offer seems consistent.

We are working on that, let’s see, maybe we can make it happen there – although a 635m² (6,834 sq ft) plot is not exactly the typical size for a bungalow. I need to check that with the municipality / local authority.

For a bungalow with a maximum net floor area of 135 m² (1453 sq ft), the plot size should definitely be sufficient.

I’m not so sure about that. There isn’t a clearly specified floor area ratio anywhere. For example, if it were 0.2, I could build 127 sqm (1367 sq ft) including exterior walls.

So if more is allowed, all the better. For a 135 sqm (1450 sq ft) bungalow, the calculation basis according to DIN 277 wouldn’t really matter to me anyway.

It was like this for us: floor area ratio of 0.2 on 650 sqm (7000 sq ft)... 135 sqm (1450 sq ft) floor area. That wasn’t enough for me.
