Plot approx. €185,000 including incidental costs
Shell construction 249 sqm 2 stories / 6 rooms / 2 large bathrooms / 1 guest bathroom / no basement! €208,000 including kitchen valued at €12,000 as a free bonus / floor slab included.
There won’t be just €15,000 of additional construction incidental costs, rather €50,000 should be planned. The €15,000 will already be eaten up by earthworks.
We have estimated incidental excavation/construction costs at around €15,000.
Interior finishing we have roughly estimated at €90,000 +
We would not initially include garage and garden, since we will very likely receive an inheritance from my wife’s side within the next 5 years.
Total costs €498,000
And how should one imagine that? You want to build in 2021, it’s finished in 2022, and you’re tapping your feet in the summer in the building sand in front of the patio door waiting for grandma’s death?!
Plan €20,000 for the exterior works (excluding carport)
Floors/tiles/doors €15,000 including labor
Painting and small jobs €2,000
For equity prices and also my father-in-law will hardly charge anything.
Materials also cost money, even for equity contributions. For 10 doors, €5,000 can easily be incurred with decent standard doors... €10,000 for all flooring is ambitious... okay, I’m forgetting the equity labor..., nevertheless:
Friends and acquaintances can be registered via the tax office and we will not pay large amounts there either.
Friends probably have regular jobs. They first have to sacrifice their free time for you and won’t (be able to) jump to your call. In the end, you will be supplicants and have to expect that a helping hand will be twisted, have a confirmation, vacation, or other things to do. Then you will have to buy craftsmen to keep things moving, which you did not plan for.
You don’t just paint a house of this size over one weekend. If you rely heavily on equity labor for many trades, then the time factor plays a role. And that can become expensive. If there’s a backlog in summer (meaning, the scheduled screed layer from the village still goes on vacation), then all others and already planned friends will be pushed back. But they will not keep the whole following year free for you...
I think €100k equity should easily make it possible, I know people who built a place for €250,000 with even €15k equity.
€250,000 are not comparable to €500,000, or better calculated with €600,000.
Whether a shell construction with so much equity labor, which is interdependent, will be financed? No idea. But I know several, whether private or here in the forum, and I also think that one should tailor their house somewhat to their available budget, otherwise sleeping well with the monthly installment over several decades is very difficult.
Basically, generous 180 sqm should be enough for 4 people. Based on the equity, I recommend 160 sqm.
