Hello everyone,
after purchasing the plot in February last year, which was fully serviced by the end of last year, we have been gathering inspiration and planning ever since. Despite rising costs and interest rates, we are excited about building our house, including some DIY work.
Development Plan / Restrictions
Plot size: 669 m² (7200 sq ft approx.)
Slope: South-facing slope, 3.90 m (12.8 ft) diagonal (approx. 7.3° incline at the street side)
Site occupancy index: 0.4
Floor area ratio: 0.7
Building window, building line and boundary: 3 meters (10 ft) or setback areas
Edge development: garage
Number of parking spaces: two per dwelling unit in front of garages, minimum 5 meters (16 ft)
Number of stories: 3 full stories (basement, ground floor, upper floor)
Roof style: gable roof with 35° to 45° pitch (if basement is not a full floor, then 15° to 25°)
Architectural style
Orientation: see draft sketch
Maximum heights / limits: wall height 6.50 m (21.3 ft) measured from finished floor level of the ground floor to the junction of wall and exterior roof surface
Additional requirements: garage roof as flat roof with green roofing, at least 40% photovoltaic panels
Homeowners’ Requirements
Style, roof type, building type: no decision yet on wood or masonry (affordable ecological)
Basement, floors: 2 plus basement suitable as living space
Number of occupants, age: 2 persons, both 26 years old
Space requirements on ground and upper floors: see draft sketch
Office: family use or home office? home office
Overnight guests per year: few
Open or closed architecture: rather open
Conservative or modern design: rather modern
Open kitchen, kitchen island: both desired
Number of dining seats: 8, preferably extendable
Fireplace: would be nice but too expensive
Music/Stereo wall: no
Balcony, roof terrace: roof terrace on garage for drying laundry, terrace, balcony-like at living/dining/kitchen area but with garden access
Garage, carport: double garage (possibly added later)
Utility garden, greenhouse: yes (greenhouse not planned at least for now)
Further wishes / special features / daily routine, please also reasons for inclusion or exclusion
House Design
Source of planning: do-it-yourself
What do you particularly like? Why? no bay windows, no spiral stairs, enough space in entrance area, access garage-house in entrance area, access garage roof/laundry room on the upper floor, level access to ground floor on north side and basement on south side, sight lines
What don’t you like? Why? staircase not located near living area, small main bathroom
Cost estimate according to architect/planner: not obtained yet
Personal price limit for house including fittings:
Preferred heating system: heat pump (underfloor heating possibly combined with cooled ceiling)
If you had to give up something, on which details/extensions
-you can give up: efficient sqm (unused areas), basement under garage or terrace
-you cannot give up: basement with large hobby workshop
Why is the design as it is now? For example:
Standard design from planner? No
Which wishes from the architect were implemented? No architect, we tried to implement our wishes ourselves on a compact footprint without feeling cramped
What makes it, in your view, particularly good or bad?
What is the most important/fundamental question about the floor plan in 130 characters?
Do you have any suggestions for improvement? What would bother you? Any tips on doing things similarly but more cost-effectively?
The basement plan is not finalized yet. In addition to utility rooms, storage, possibly a bathroom (for quick cleaning and a potential future granny flat), a space-intensive hobby needs to be accommodated here. We are considering adding a basement under the garage or terrace or both. If you have any preliminary tips or rough cost estimates, please share.
If you need further information, just ask.
Thank you all!

By the way, I have unsubscribed from the thread; all the popcorn for the Simshausthreads is really adding up on the hips, and our house has a flat roof, so I can’t install a grease extraction system in the attic ;-)

Are you still working with a floor area ratio of 0.4?H

Floor area ratio: 0.4?Yes, that’s why the path on the south side is green.So, to summarize the basics briefly:
The floor plan shown needs extensive revision, and combined with the slope and the garage, it is financially borderline. Including the requirements for the basement will definitely exceed the budget.
The question remains:
Are you willing to compromise on the basement, for example by reducing the size of the workshop, or can you significantly increase the budget (would a bank still approve this, and would that still be feasible with children, or would the wish to have children have to be sacrificed and the house planned smaller accordingly)? Are you prepared to invest that much additional money specifically for the workshop basement?

For rough location sketches, you would need the precisely measured plot including all building envelopes, setbacks, or other zoning plan details. Contour lines were somewhere already, I believe. The contour lines are relatively inaccurate; we have fully surveyed the plot using a grid of 4.5 m x 3 m (15 ft x 10 ft). I can gladly compile the information, at the latest by the weekend.

If I remember correctly from occupational safety and workplace regulations during my apprenticeship There is a significant difference between employing staff or not.

That sounds like a perfect recipe for a disaster upper floor. I agree, that would lead to even more restrictions. The structural engineering and the related static considerations strongly depend on the construction method used; accordingly, further limitations due to the building technique would have to be taken into account before planning.

I ask again, where is the construction taking place? In Bavaria, in the greater Regensburg area.

Are you planning to do the carpentry work yourself? That would certainly be possible. The garage, in principle, is not a big problem—if it weren’t for the green flat roof... Perhaps switching to photovoltaic panels as a standalone roof covering might be an option (which is also allowed according to the zoning plan). I’m happy to receive inspiration on this. Recently, I heard of a green metal roof where the vegetation grows between the standing seams.

No ground-level exit haydee schrieb:
How do you plan to get materials from the street into the workshop? Do you never want to use a crane or similar? In my design, there would be two large doors in the basement facing south. A gate in the fence allows access relatively close to the workshop.

Load-bearing columns There is no doubt that a few will be necessary. These must be positioned according to the structural engineer’s specifications. This again depends on the building method and the loads above. However, the columns can certainly be minimized; I am not overly concerned about this at this stage.

150 sqm (1,615 sq ft) living space * 3000 Euro = 450,000 + 50,000 garage + 150,000 basement + 50,000 landscaping = 700,000 If the garage is postponed or completed entirely as self-build, the cost would come closer to approximately 650,000 €. There may also be potential savings on landscaping since agricultural equipment is available.
So, if one is cautiously optimistic, it could be said that, in theory, with some compromises and a lot of own work, it would be achievable.

From the presentation, I assume it is built on stilts with point foundations?
How much additional effort is involved for the extra floor slab (or ground slab of the house)?

The shown floor plan urgently needs revision, and combined with the slope and the garage, it is financially borderline. When considering the basement requirements, the budget will be exceeded.
The remaining question is:
Are you willing to make compromises with the basement or reduce the workshop size, etc., or can you significantly increase the budget (would a bank cooperate, and is that feasible together with children, or would the desire to have children have to be sacrificed, allowing the house to be planned smaller accordingly?), and are you willing to invest that much extra money for the workshop basement? Thank you for the summary. Some compromises are acceptable in certain areas, but based on our current knowledge, we do not want to give up all wishes regarding the workshop. We will definitely reconsider the budget again over the weekend.
I would like to thank you all in advance for your responses. Unfortunately, we are not quite as quick during the week to reply...
