ᐅ Budget Planning. Cost Estimation

Hello, after months of comparing and obtaining several quotes, we think we have found the right solution. It will be a prefabricated house.

What still concerns me is whether we have budgeted the costs correctly.

Budget: 370,000€
House offer with foundation slab (we do not want a basement):
192,000€ for 146m² (1571 sq ft) with some work to be done by ourselves (flooring, wallpapering, plumbing fixtures, floors, doors)
Material for self-performed work, according to the house provider: 13,000€ (seems a bit low to me?)
Additional cost for possible upgrades to the standard house features: 5,000€
Land with notary fees: 96,500€
Additional construction-related costs (site services, permits, etc.): 30,000€
Kitchen: 10,000€
Furniture: we already have everything
Garage: not planned for now
Heater or stove: no idea, estimated 1,000€
This leaves 35,000€ for other expenses (terrace and garden work to be done ourselves).
Is this realistic?

The upgrades from the standard package seem a bit limited to me. I don’t know what the standard of the house is and what you consider acceptable, but so far we have had upgrades for the roof tiles, the windows (transom windows, insect screens, electric shutters), the front door, the interior doors, and so on, and we have already paid significantly more than $5,000, not to mention the electrical work. That alone will probably consume a large part of your budget.

Thirteen thousand dollars for materials also seems tight to me. But as I said, you really can’t generalize. One person wants gold-plated faucets, while another is fine with the cheapest option from the hardware store. It really depends on how high you set your expectations.

The kitchen? Ten thousand euros? How large is it?

Can you tell us which manufacturer you are building with or planning to build with?

Do you think the kitchen is also too small? It will be an open, modern kitchen, but we will install it ourselves. We have connections for the electrical appliances and can get them at a good price.

Is it okay if I mention the company here? It will be a Hanlo house.

Okay, we still have 35,000 euros for other expenses, some of which could be used here. We will do the garden ourselves, so we only need material costs; we don’t want anything complicated.

We don’t need electric roller shutters or any of that extra stuff.

The hardware store is fine. It should be a walk-in shower and modern, but not the most expensive option.

For us, it's more like we could invest more in the house, but we actually don't want to, because we don’t want to live just for the house—we also want to live well otherwise. I was just unsure whether our expectations are realistic with normal standards.
