Hello everyone,

I have purchased a plot of land and would like to hear your opinions on the design.
The plan is for a multi-family house with 3 residential units, one apartment per floor. Possibly, we would use a room in the ground floor stairwell area as a laundry, storage, and utility room. The house should have a modern and functional layout, ideally with plenty of natural light and an open living, dining, and kitchen area. It is also very important to me that each apartment has a balcony or terrace where residents can comfortably sit and spend time.

Here is the brief:

Zoning plan / restrictions
Plot size – 523m² (5,628 sq ft), 19m (62 ft) wide, 27.5m (90 ft) deep, rectangular
Slope – no
Site coverage ratio – 0.4
Floor area ratio – 0.8
Building setbacks, building line, and boundaries – 5m (16 ft) from the street, 3m (10 ft) from neighbors, no boundary restrictions to the garden
Edge development – "On every building plot, a free-growing hedge or trimmed deciduous hedge must be planted and maintained along at least one plot boundary." Nothing more was found in the zoning plan.
Number of parking spaces – 1.5 per residential unit
Number of floors – 2 full stories
Roof type – all roof types permitted
Architectural style – no specifications
Orientation – south-facing
Maximum heights / restrictions – main building max 11m (36 ft), stairwell max 7m (23 ft)
Other requirements – none that have significant influence on the design

Client requirements
Style, roof type, building type – modern multi-family house with 2 full stories plus a recessed top floor with a flat or mono-pitched roof
Basement, floors – no basement, 2 full stories plus recessed top floor
Number of residents, age – unknown, approx. 3-5 people per unit
Room requirements on ground and upper floors – ground and first floors approx. 130m² (1,400 sq ft), attic floor approx. 90m² (970 sq ft)
Office: family use or home office? – family use
Occasional overnight guests per year – few
Open or closed architecture – no preference
Conservative or modern construction – modern
Open kitchen, kitchen island – open kitchen without kitchen island (too expensive 😀)
Number of dining places – 1 per unit
Fireplace – no
Music / stereo wall – no
Balcony, roof terrace – yes, balcony is very important for the apartments on the first and attic floors
Garage, carport – no, outdoor parking spaces
Utility garden, greenhouse – no
Other wishes / special features / daily routine, including reasons for these choices – It is important to me that the apartments are designed so tenants want and can live there long-term. Therefore, I am considering a laundry room on the ground floor that can also serve as a utility and storage room. Otherwise, the apartments should have sufficient space on the balconies.

House design
Designed by – my brother is a civil engineer who designed the plans
What do you particularly like? Why? – large living, dining, and kitchen area on the ground floor, number and size of bedrooms
What do you dislike? Why? – the terraces on the ground floor are located at the west corner with the exit there, and the balconies on the first and attic floors are in the east corner
Estimated price according to architect / planner: €520,000 including VAT. I am contracting the trades myself.
Personal budget limit for the house, including fixtures: €520,000
Preferred heating technology: district heating is more or less required by the city

If you had to give up something, on which details / extras could you do without?
- Could give up: open kitchen, guest toilet
- Could not give up: balcony, terrace, storage room

Why is the design like it is now? For example:
Standard design from planner? – It is already adapted to the plot conditions and our ideas. But I am not sure if it is "right" for a multi-family house. Especially the issue of balconies and the laundry/storage room—I am not sure if these all fit well.
Were client wishes implemented by the architect? Basically, all wishes were implemented. I am just not sure if our wishes are the "right" ones or if something could be better done.
A mix of many examples from various magazines...
What makes the design particularly good or bad in your opinion?

First floor plan of a house with corridor, stairwell, and several rooms.


Attic floor plan of a house with several rooms, stairwell, and dimensions.


What do you think of the designs? How do you find the layout? What do you think about the laundry/storage room on the ground floor?
What do you think about the balcony situation?

Thanks for your feedback!

Unfortunately, nothing can be read, and some measurements on the walls would also be helpful. Where exactly are the washing machines supposed to go?

I tried to incorporate the concerns raised by @ypg.

Made the bedroom larger and moved the door. Furnished the rooms. The utility room and office are a bit wider. The master bathroom can also have an entrance from the hallway. A shower bathtub is planned in the children’s bathroom.



The district heating distributor can be placed in the utility room and used for all three residential units. Therefore, in my opinion, no utility room is required on the upper and attic floors.

Hello hanghaus2023,

My dream home is a house on a slope.

Thank you for your input. I find your idea about the bathroom door in the bedroom interesting. I will have to think that over. I like your suggestion regarding the utility room and office. I have incorporated that into my new design. However, I would probably have to move the washing machines to the guest restroom, which is not ideal since the children’s bedrooms are nearby. Ideally, I would place the washing machines against the wall next to the office.

We should agree on a direction if north isn’t at the top.
Otherwise, it’s hard to compare.

I like the open living area.
Some things are similar or swapped. The bedroom door needs to be moved.
Your utility room does not meet the necessary 180 x 200 cm (71 x 79 inches), so the design is basically not workable.
If you want the utility room to be accessed from outside, it must be placed so that no car would block the entrance and a technician can easily reach it.
Your office is about 170 cm (67 inches) wide or so. For the downstairs bathroom that narrow shape is not a big issue, but furnishing the office might be tight if you want to move your chair around.

Hello YPG,

I have adjusted the utility room according to hanghaus2023’s idea; the office and bathroom are now a bit smaller but still large enough, in my opinion.

Here is the new draft—what do you think?

Yes. You are right, the quality is unfortunately quite poor, and the tool I am using does not have an option to display measurements.

How wide are the doors? In my opinion, not all doors need to be designed to allow a 125kg (275 lbs) person to pass through. However, the looming requirement for "barrier-free access" still hangs over the ground floor apartment.

Why not add some windows to the drawing?

Try adding the windows to the plan.

The wall openings are currently 1m (3 ft 3 in) wide in the current design, which can probably be reduced to 90cm (35 in) and optimized a bit. The office door already has a 90cm (35 in) wall opening.

What else do you think is needed to achieve accessibility? From what I see in the building regulations, the requirements are not very specific.
The windows are now included; in the living room and kitchen, I would only install ventilators.

I have planned the washing machine and dryer in the storage room. This also provides a short path to the terrace.
