Prefabricated house planning semi-detached house with budget limit

Hello,

Dreams are indeed a nice thing; just hardly suitable when building a house.

We have set a limit of €300,000, of which €100,000 is for the land. We definitely want a basement.

Slope: yes, gently sloping from north to south, about 30-50cm difference across the property
Basement, floors: basement, ground floor, upper floor
Basement: workshop, storage room, possibly utility room, due to the slight slope it would also be possible to place the guest room on the basement south side and expose the basement windows. I grew up that way myself and it worked well for me.
Garage, carport: yes, at least 1x carport + 1 open parking space.
- There are 5 rooms on about 130m².

Personal price limit for the house, including equipment: €200,000 including basement
Preferred heating technology: geothermal + solar

Land: TEUR 100
Single-family house 130 sqm according to energy saving regulations: TEUR 208
Usable basement: TEUR 42.5
Conversion to living basement: TEUR 20
Geothermal heat pump: TEUR 10
Drilling depends on soil conditions. Can be anywhere from TEUR 10 to 15
Solar: TEUR 6
Painting/floor coverings in EL: TEUR 20
Additional construction costs: TEUR 50 due to slope
Outdoor facilities in EL: TEUR 10 (only the essentials)
Reserve for extras: TEUR 10
Carport: TEUR 6

All in estimated investment: TEUR 495


I suspect a condominium would be the wiser decision within the desired budget

Rhenish greetings

only 200,000€ too expensive, there's still room for improvement.

: how do you always come up with 20,000€ for floor and wall work done by yourself? "a few" tiles are always included with these houses. so the floor coverings for the sleeping and living areas are still missing. let's round up to 100sqm (for very large houses downwards). for 60€/sqm in materials you can get great floor coverings including accessories, installation is DIY, so 6000€ material.
wall work is base area times 3.5 including ceiling (130sqm x3.5 = rounded up 500sqm area). 1 sqm wallpaper costs with all accessories nicely rounded up 5€. that makes 2500€ for painting material.
if I now carefully round up both sums again! I'm at 10,000€. this amount is already premium class, you can do it for half the price without major compromises. (we managed with 3€/sqm wall/ceiling and floor covering 22€/sqm laminate including underlay)
if you have these works done, 20,000€ could probably be right, but then it wouldn't be DIY.

I can only agree with that. We also did about 100 sqm of floors ourselves, as well as primed, wallpapered, and painted a larger area on our own and stayed well under 10k including all materials and tools. The cost for having the remaining square meters tiled was under 5000€. If you do everything as self-performance, I would also say well under 15k.

Manoman, I really didn’t expect so much feedback and then all the celebrities... Thanks!
With Germany’s Search for the Super Homebuilder, I probably wouldn’t have become a superstar architect with the jury’s rating

I can’t respond to everything that fast.
What I have already done are the incidental construction costs and the EL.
I have cobbled together the following incidental costs from the web; something is obviously missing due to the hillside location. At first, I just relied on srtm geodata. But the development plan states the height. The difference in height is not 0.3m. It’s more like 2m!
Can’t I just build much smaller and completely expose the basement on one side and live on the garden side? That would have to bring about a huge saving. Maybe I don’t even need a house anymore, but just live in the basement like the Hobbits?[ATTACH alt="tiny-houses-Wandarbeiten-Eigenleistung-bodenbelaege-Keller-bnk-150074-1.jpg"]11994[/ATTACH]

Ok. A little joke on the side.

I will now quickly google additional costs for hillside locations, this was my original calculation:
Building permit 2,000.00 €
Surveying 2,500.00 €
Structural engineer - €
Soil report 1,000.00 €
Architect and construction management ? €
Construction road 450.00 €
Excavation for basement/foundation slab 1,350.00 €
Removal of excess soil 3,600.00 €
Development and house connections 7,500.00 €
Insurances 300.00 €
Property transfer tax 3,300.00 €
Notary 1,400.00 €
Land registry office 500.00 €

Total ~24,000 €

For the interior finishing, I planned to do it myself:
Interior fittings material m² €/m²
Parquet 5,000.00 € 100 50
Tiles 1,500.00 € 30 50
Filling/spackling 2,000.00 €
Painting 2,000.00 €
Interior doors 1,000.00 €

Total ~12,000 €

But I still have a small question about my floor plan... Is it at least somewhat sensible? Or am I just as way off there as with the costs? I almost fear it will be ripped apart just the same.

Yes .. it probably isn’t that successful. Is the eaves height really 4 m?

I would never make the knee wall less than 1 m though.

A look at the ground floor:


8 m external dimension leaves about 720 cm internal dimension. WC approx. 150 and probably 18 cm load-bearing wall, so there remain max 552 cm for kitchen and probably dining area ... That’s tight.

Stairs ... everyone has to walk through the living area first (how do you want to place a sofa etc. there?) to get to the upper floor.

The stairs will also fail because the head clearance below the landing will probably be too narrow:


4 steps = approx. 72 cm ... with a finished ceiling height of 250 cm you won’t have 180 cm head clearance at the edge of the stairwell.

Regarding the room sizes upstairs ... wouldn’t it be an option to put the parents on the ground floor and have a small guest room and 2 larger children’s rooms upstairs?

However, as I said, everything with a different stair design.

Just google Tiny houses, maybe you'll find something there.
