Cost calculation single-family house bungalow 110 m²

For comparison: We have 2x3, 2x2, 2x1 sockets plus a total of 3 in the window recesses. In addition, TV and 2x LAN. And that in a 25 sqm living room. So far, I haven't been able to complain about having too many sockets. For me, there should be a double socket in every corner of the room. You need quite a few behind the TV alone. TV, receiver, PS4, possibly a stereo system... That's already four sockets gone. Then possibly decorations or lighting. I don't think it makes sense to start with a triple distributor in a new building. Demands aside, but if I were to inspect a 10-year-old house and found only 5 sockets in the living room, I would deduct €15,000 from the purchase price for a new electrical installation.

Of course, I’m not bothered by having more sockets. Not at all. But you have to weigh whether I prefer to pay extra cost XY for a sophisticated, comfortable socket network or invest the money in an "invisible" distributor behind the living room wall unit and then allocate freed-up budgets to outdoor areas, doors, or similar. The detailed planning of the sockets in terms of location (and then additional needs) is still pending for me. But I feel that a double socket in every corner of the living room would be enough for all contingencies plus TV and LAN. In the current 27 sqm living room, we are currently using 4 sockets. The issue of purchase price/house value is of course an argument for many. But not really for me. Ultimately, I primarily plan on living in the house myself until the end if all goes well. Paying attention to the resale value when building a house requires a lot of foresight. I don't want to speak ill of that. But it’s the wrong motivation for me if I design the house primarily for my/our needs... But I will reconsider it once more.

For me, every corner of the room needs a double socket. Just behind the TV you need quite a few. TV, receiver, PS4, possibly a system... That already uses up four sockets. Then possibly decoration or lighting. I don't think starting with a triple distributor in a new building is sensible.

Double sockets in every corner, definitely. But those batteries of sockets behind the TV... two years after moving in, you get the TV background lighting, a new set-top box, the wife wants a decorative fountain or something else you don’t know yet, and... suddenly you need a distributor again!

If so, you really have to prepare for the worst case and should put at least 6 sockets plus Sat/LAN in every corner where the TV might stand. And if it’s not covered by furniture (because after some time a new sofa will come, and the TV sideboard will have to move a bit to the side), it looks rather bad. And for plugging/unplugging you often have to move the furniture again.

Ok, two more things:

Your overburden increases by another 30 to 40% due to loosening at the surface. So you should add that as well!

Very good tip, thank you very much!

And you can clarify the connection fees (water, sewage, electricity) with two calls. Or you can ask the neighbors already living in the development area.

I'll add that to my to-do list for today. Good idea.

Regarding the loan, you can safely add another 10k on top alongside your reserve. Assuming a 5% special repayment and a 200k loan amount, you could repay it after the first year if unused, which would cost you about one or two "Blaues" in interest costs... better to have that flexibility in reserve than to have to refinance later. Provided, of course, that you stay in the same interest tier.

I would have that calculated, sounds reasonable. I generally hope for a good offer regarding possibly unused loan amounts. Although I’m basically of the opinion that leftover balances can probably be put to good use in case of doubt, if there is a way through special repayment or non-use – without large penalties for non-withdrawal – then I’m open to that as well. We shall see.

Don't skimp on the outlets. At least one on every side of the room. More only if needed or if money is no object. If necessary, a single outlet can easily be upgraded to a double or triple outlet later.

PS: In every room of our new building, I had an empty conduit installed leading to the connection room. It costs little and provides flexibility. Whether a sauna is installed later or a fiber optic backbone is laid in a few years, or whatever...

Our house construction project is taking shape and we are preparing the appointment for financing and want to arrive there with the most realistic cost expectations possible.

If someone here could take a look, that would be tip-top:

The plan would be financing of €275,000. Equity intended for buffering is another €10,000.

Is that realistic?

Good morning,

we have calculated similarly. At a sqm price of about €1,500 you’re still "doing well".. We have already had some talks with construction companies in Saxony-Anhalt and currently we are between €1,600 and €1,800 / sqm.. I would rather calculate with a slightly higher sqm price as a buffer possibly. Do you already have a construction company? You come from S-A after all. Unfortunately, I cannot send you a private message.. Sorry if I’m spamming here.. May I ask which general contractor you have decided on?!

Thanks

Regards

Steven

Morning, we have calculated similarly. With a price per sqm of about €1500 you’re still getting off "well".. We have already had some talks with a few construction companies in Saxony-Anhalt and currently we are between €1600 and €1800 / sqm.. I would rather calculate with a slightly higher price per sqm as a buffer, possibly. Do you already have a construction company? You also come from S-A, right? Unfortunately I cannot send you a private message.. Sorry if I’m spamming here.. May I ask which general contractor you decided on?! Thanks Regards Steven

Based on our price (as you know also S-A) I find €1400 quite realistic if you don’t want total luxury. We are even below that (without considering the basement) despite electric roller shutters, chimney for fireplace, anthracite windows, laundry chute to the basement, captain’s gable with floor-to-ceiling windows, extended roof (as sun protection), corner bathtub, floor-level shower, 2x towel radiators and triple-glazed windows etc. What kind of features do you want that drive the price?
