Hello everyone, I would like to share with you an initial draft from the architect and ask for your feedback and opinions.

Zoning Plan/Restrictions
Plot size: 870m² (9369 sq ft)
Slope: south-facing slope
Floor area ratio (FAR): 0.4
Building floor area ratio (FAR): 0.8
Knee wall height: max. 0.75m (2.5 ft)
Building window, building line and boundary
Edge development
Number of parking spaces: 2 + 2 in front
Number of floors: 2
Roof style: gable roof
Architectural style:
Orientation: garden facing south
Maximum heights/limitations
Other requirements

Homeowners’ Requirements
Architectural style: classical
Solid wood house with wooden cladding on the upper floor
Roof style: gable roof with about 34°, open roof slope, no attic!
Building type
Basement: with basement
Number of floors: 1.5
Number of occupants: 2 adults (38, 39) + 1 child (2) + possibly another child
Space needs on ground floor, upper floor, basement:
The upper floor is a retreat area for the family, the two children’s rooms can optionally be combined if there is only one child. The parents’ bedroom and bathroom do not have to be particularly large.
On the ground floor, a home office (for self-employment) is very important. The focus is on the kitchen and dining area with views of the south-facing slope. The living room should be somewhat separated but does not need to be a separate room. The staircase area should be open, since the main heating will be from a stove. Cooking will happen regularly.
The basement should represent a second living unit initially for KFW 55 funding. Here is the guest area and a large gym.
Office: yes
Guests per year: 20. Family members do not live on site but visit often
Open architecture
Conservative construction method
Open kitchen, cooking island: yes
Number of dining seats: 6–8
Fireplace: yes, masonry stove
Music/stereo wall: no
Balcony, roof terrace: terrace on the west side
Garage: double garage

Further wishes/special features/daily routine, also reasons why certain things should or should not be included

House Design
Planner:
- Architect
What do you particularly like? Why?
We really like the upper floor.
Open living/dining area with large windows facing the garden since it’s not overlooked.
The basement offers enough space for technical installations and storage.
The basement garage has space for garden tools and a workbench.
South-facing roof is well suited for photovoltaic panels.

What do you not like? Why?
Cost estimate per architect/planner: 450,000
Personal price limit for the house including equipment: 550,000 (furniture is available except bathroom and kitchen). Lots of DIY work planned for interior finishing.
Preferred heating technology: water-circulated masonry stove, buffer tank with heating element, large photovoltaic system, wall heating

If you have to give up on certain details or expansions
You could give up: open space, bathtub
You cannot give up: office, garage, basement

Why has the design turned out the way it has? For example:
Which wishes were implemented by the architect? Yes
The challenge is in the ecological and sustainable timber construction and the budget.
What do you think makes it particularly good or bad?

What is the most important/fundamental question about the floor plan, summarized in 130 characters?
Is the living area sufficient? Does the floor plan work well in daily life?
Is the staircase placement suitable? Is the hallway/entrance area large enough?
What do you think about the windows in general?

Why are you using wooden studs inside?

We don’t want exposed solid wood walls everywhere. The interior walls will be finished with plaster.
This allows us to contribute some of the work ourselves, so there is potential for cost savings here.

Best regards

What speaks against having the living area in the basement, including access to the large garden, is that we plan to build all exterior walls with solid, visible wood. We wouldn’t get the same indoor climate or feeling in the basement with concrete walls.

That somewhat contradicts the idea of a timber frame. By the way, solid wood can also be covered with drywall and paint fleece.

Here is an example of a solid wood wall. There are now several systems that can effectively construct a solid wood wall without glue and plastic. During the detailed planning stage, the electrical installation is taken into account, and the channels are pre-routed. All good. The wall heating is installed on the interior walls (wooden studs). That works too. ...
So: glued laminated timber (glulam) without glue but with pre-routed electrical channels is practically one of the most expensive options you can choose (unless you add a clay plaster with wall heating on top, which would be really great but not cheap). Also, the planning is extremely demanding! For our project (for the entire building, but especially for the solid wood walls) we had the opportunity to view the house in 3D during the design phase and to selectively display layers such as just the electrical work. This allowed us to check every electrical channel and outlet. Still, there were small details that were not perfect. We were then able to adjust these on site since they were concealed behind drywall. With the construction method you are considering (if I understood you correctly), that would not be possible. There are only a few selected suppliers offering solutions without glue and “plastic” (where else would plastic be in solid wood walls?). These suppliers are currently either sold out or even overloaded, or they simply don’t have the materials available for installation. This does not align at all with the planned cost savings through owner-conducted interior wall work (interior plaster). At the moment, I see the construction planning as more of an early beta phase 😉

During the planning phase, we had the chance to view the entire house in 3D, especially the solid wood walls, and to switch layers on and off, for example, to display only the electrical layout. This allowed us to check every electrical channel and every outlet. Still, there were minor details that weren’t perfect. We were able to fix those on site because they were concealed behind drywall.

Thanks for your advice. We have everything on our radar. Factory planning is obviously very important. We already have a partner for that.

You will have limited flexibility later for adding electrical outlets, switches, cables, roller shutters, etc.

What happens if something is defective?

How is the shading installed? Where are the motors and other components hidden?
