@heltino: are you talking about net or gross?
I have offers (although from prefabricated house builders) in which the item interior doors is listed at about €8000 net.
Front door with 2 side panels around €5000
Garage door I calculate between €2500-3000
Then everything plus tax.
I also included a buffer.
Did I forget any items to calculate or am I on the right track? So that I can move in afterwards...
The staircase is supposed to be a wooden staircase... That comes on top of it... or can I hide that in the other costs?
Thank you very much!
That’s hard to say in general, it always depends on exactly what you’re looking for and what you install. As a rough orientation, here’s what I paid for these trades (individual contracts, no house manufacturer!): Interior door €220 (simple variant, basement) up to €350 (fancier variant for living rooms). Each price net including installation and complete with frame. Front door: high-quality branded plastic door including 60cm glass element on the left and 50cm glass element above. The whole thing with stainless steel applications, a 1m long stainless steel handle, and laminated safety glass (VSG). Final cost after tough negotiation: €3200 (GROSS!!!). Staircase to the attic (the rest is concrete for me): two-stringer staircase with finger-jointed beech wood, railing and installation: €2600 (gross!). My house builder went bankrupt during the construction phase, so I had to continue with individual contracts. And you’d be surprised how much money you can save! Example wooden staircase: I took the same staircase from the same manufacturer (!) and got it €2000 cheaper than the house manufacturer had "calculated". Example windows: I got better ones (0.5 insulation, fully insulated electric aluminum shutters) €1600 cheaper than planned by the house manufacturer (he had 0.9 insulation, plastic shutters with manual strap guide). He calculated €18,000, I paid €16,400 (gross) including RAL installation by the window installer. Your garage door is very generously calculated, check online. Then you get a feeling for the prices. German brand products can be found at about €1000, with electric drive about €1700... as a simple up-and-over door variant from €500. I did not consider cheap shipping goods and always planned and bought well-known brands, installed by a professional company. I had EVERYTHING done by local specialist companies including installation and warranty, no cheap junk! Since I don’t know exactly what you plan and want, I can only give hard-to-give concrete advice. The range is simply huge. A front door can cost between €700 (DIY store junk) and €12,000 (aluminum PREMIUM-DESIGN-SOMETHING)...and we’re only talking about the term "front door" in both cases. Caution is also advised when choosing the heating! The marketed "heat pump" is not always the best solution. Air heat pumps are not always economically sensible, many also make a lot of noise that you then get to enjoy on the terrace. Geothermal variants often cost so much extra due to drilling that you cannot save the extra costs within 20 years. I had a specialist company and a heating manufacturer come to the construction site and then determined the most sensible solution for me using a heat demand calculation and KFW documents. I then bought gas condensing boiler with underfloor heating, 400-liter solar storage and well-planned circuit control. Costs me about €150 more per year in gas consumption but saved between €6,000 and €12,000 on the heating system compared to various heat pump variants. (Calculate yourself how long you have to heat until you just break even. The fairy tale of "independence from gas prices" is told by everyone, but nobody voluntarily tells you that a heat pump permanently needs electricity (€50-80 per month) and must also electrically heat at very low temperatures.) I now have something (not yet moved in, so based on calculations) between €50 and €70 per month in gas costs. The neighbor has a groundwater heat pump and so far uses about €40 per month on electricity on average. But he hasn't experienced a harsh winter yet. Looking at that... it’s never profitable. Even if he were to save a consistent €30 per month... he paid €8000 more. Without interest, you simply need 22 years to save the additional costs! In general, you have to be very careful with these "eco stories," many are a money pit. Savings are often advertised, the additional costs and the resulting time until something pays off... are always nicely calculated. Remember: every heating system, no matter which, is 20 years old and possibly ready for replacement. So if you only recoup your extra costs after 18 or 20 years based on a theoretical projection... forget it. But you can talk endlessly about that, I advise you to generally inform yourself on the internet. Forums, experiences of other home buyers... the direct manufacturer pages (windows, doors, bathroom ceramics, etc.). Then, although you won’t be a professional like me either, you can hold your own, understand what it’s about, and have a feeling for whether prices are justified or not. But don’t get stuck on small stuff like "interior doors," that’s not a big cost factor by God and has only limited potential for hidden costs. Cost traps basically lurk in two areas: 1. In the construction contract (what is not precisely described and included, you haven’t bought!) 2. With the land (soil survey must be done BEFOREHAND (about €1000 which is worth it, so you avoid nasty surprises like groundwater, soil replacement due to bearing capacity, etc.), inquire about and have the exact development calculated (length of connection paths, how is the sewage issue regulated). We had a soil survey done, knew we had groundwater and needed a waterproof concrete tank, knew we had partly clay soil... so we only had marginal additional costs. I have to check, but it should have been about as follows: €1000 for pre-screening in the garage driveway area, €2400 "proportional development contribution for the sewer" to the city, €2800 open water management during the construction phase. That was another almost €6-7k in additional costs. Without a report, ask my neighbor who wanted to save the €1000, you’re at the mercy of the builder as a cash cow. During construction, he then finds many "couldn’t have known" items and cashes in like a champion. Therefore, the soil report must happen before signing the contract and the building contract must specifically refer to it!
