Bruchpilot276 Oct 2020 16:50Hello everyone,
I would like to introduce our project using the questionnaire. We plan to start construction next summer in Bavaria and are currently three people involved. We would appreciate many opinions, suggestions, criticism, and ideas from you. Thanks in advance.
Development Plan / Restrictions
Plot size approximately 1300m² (existing)
Slope no
Floor area ratio 0.4
Plot ratio 0.7
Number of parking spaces 2
Number of stories II = ground floor + attic
Roof shape gable roof 38°–47°
Style classic?
Maximum heights / limits
Ridge height 9m (30 ft)
Knee wall 0.5m (20 inches)
Dormers up to one-third of the roof area
Garage also with pitched roof
Owner Requirements
Basement, floors basement + 1.5 floors
Number of people 4
Room requirements on ground and upper floors see plan, we planned from “inside out”
Office home office 1–2 days/week + leisure
Overnight guests about once per month
Open or closed architecture?
Open kitchen with sliding door if needed to close
Number of dining seats 8–12
Fireplace no
Double garage with storage room for bicycles, motorcycle
House Design
Planner Do-it-Yourself
What do you particularly like? Why?
Orientation of rooms; large living/dining area; spacious entrance without a vestibule; storage/coat room as multifunctional space on ground floor
What do you dislike? Why?
Knee wall at 0.5m (20 inches) with corresponding roof slopes. We tried to take this into account.
Cost estimate according to architect/planner: $500–550k excluding additional costs, without considering subsidies
Personal price limit for the house, including features: $550k
Preferred heating technology: likely underfloor heating with air-to-water heat pump + photovoltaic system + small battery storage, but we still need to study this in more detail
If you had to give up some features or extensions,
What could you do without? Carport instead of garage is being considered (price issue); considering skipping the basement in favor of a slightly larger house including attic development (technical/laundry room) + somewhat larger garage (workshop)
What could you not do without?
Why did the design turn out the way it is? For example:
We considered where on the plot the house should be located and where the garden, accordingly planned the garage and room orientation
Then we planned from the inside out and eventually limited the house to 13 x 10m (43 x 33 ft) (budget)
We haven’t finalized window details yet, only ensured that every room receives natural light
What is the most important/basic question about the floor plan summarized in 130 characters?
We would like your opinions and suggestions on the plan, this is our first house build
Do the rooms on the upper floor feel cramped due to the low knee wall or is it okay?
Does it make sense to also request offers from prefab house manufacturers, or is the design too custom?
How do you evaluate the cost estimate?
Where could we sensibly reduce size?
Plot with building envelope and house — see pictures
All images: top = north
The ridge runs along the west-east axis
To the north is an open field
To the south is the street access and the rest of the development area
To the west are still 3 free plots
To the east is a field path and then an undeveloped plot

What do you plan to use the basement and the roof over the garage for?
How much of the work do you intend to do yourselves?
Make sure to mark the 2-meter (6.5 feet) height line in the attic.
Draw the desired or existing furniture to scale.
I would move the house as far north as possible.
However, this will likely increase the connection costs.
The ground floor hallway and bathroom are relatively large, as is the cloakroom. There is already enough space to house the building services there. This area still needs to be optimized. The cost per square meter is roughly 2000 euros.
I don’t like the kitchen at all. Others can probably provide more input on that.
The terrace should have a closer connection to the kitchen.
Timber frame general contractors can, of course, build the house. The catalog home is rare.

Unfortunately, according to the development plan, the garage roof must be constructed like the house roof, which means a pitched roof. We would have preferred a flat roof.
The 2m (6.5 ft) line and additional furniture in the correct scale will be added. Most of the furniture currently shown is mostly to scale, but I will double-check that.
Moving the house further north: We will reconsider this. We initially planned it that way but then were advised that since our plot is quite large, placing the house in the middle also makes sense. This way, for example, we could build a pool on the north side later (ideally away from the street) and still have sun there all day. I roughly calculated this using the sun path for one side. By the way, we are only allowed to build within the white area.
It’s true that the ground floor on the east side is quite large. Due to the low knee wall height, we chose the footprint so we could have reasonably sized rooms on the upper floor. It is a bit spacious downstairs.
I will wait for the advice on the kitchen.

A 0.5-meter (1.6-foot) knee wall does not align with the upper floor. None of the planned furniture works: the toilet is under 2 meters (6.6 feet) high, the built-in closet is 2 meters (6.6 feet) tall? The double bed is not accessible...
The kitchen is also half unusable, barely walkable. The sink is placed behind the bar section, making everything cramped at the highest level: out of 17 square meters (183 square feet), only 6 square meters (65 square feet) are effective kitchen space. The hallway is enormous... without added value. The storage furniture is spread around.
In my opinion, the individuality here is something that could be adjusted: yes, going for a standard house, whether solid build or timber frame construction, is worthwhile.

The kitchen layout won’t work like this. If a side-by-side refrigerator is included, the wall section along the top of the plan needs to be about 505cm (200 inches) long, and the wall on the right side of the plan should be shifted slightly further right to keep the wall section reasonably symmetrical (including a storage niche).
Parallel to the wall section, place an island approximately 370 x 100cm (146 x 39 inches) in size, with a sink and cooktop.
