Plot: 55-70 TEUR including incidental costs
(Land reference value is 65 EUR/sqm -> that would be 50 TEUR)
Definitely determine the market price, the land reference values are very abstract in some places. In our village, the market value is easily 50% higher.
Earthworks: 30 TEUR
This is rather tightly calculated. Do you need to dispose of excavated material? Then you also need a budget item for that.
Outdoor facilities: 30 TEUR
What would be possible within the budget?
Urgently necessary: driveway, terrace, splash protection for the house
[*]You can gravel the driveway cheaply, it looks neat for a long time - when you have money again you can consider an alternative. Choose the material size so that you don't carry stones into the house.
[*]Terrace - material / size? For a Bangkirai wooden terrace you build yourself, you get the price per sqm for 25-35€ material. For paving with contractor expect 60€ / sqm.
[*]Splash protection for the house - as plaster/paint should be included in the house price.
[*]Design a garden plan and then see what you want to do yourself, when you want to do it and what you need for it. Simple stairs / steps you can easily manage material-wise for 30 € per step at 1.5m width, don't save on the price of plants and bushes and choose mostly native plants - that saves work and is better for species conservation and nature.
[*]Fences can potentially be expensive.
You can easily get by with 30K if you have patience and do some of it yourself. If everything should be done by a contractor, it will be tight.
House (turnkey, incl. floors and painting): Max. 320 TEUR
No garage planned, but maybe a cheaper wooden carport, what rough costs would come on top?
It's a question of the construction description - read carefully!
Miscellaneous: 20 TEUR
Kitchen: 10 TEUR
Furniture, lamps, small stuff: 10 TEUR
It depends on what you bring with you when moving and how high your standard for immediate perfection is. The budget is easily doable, I still find it tight.
