How many home builders do you know who bought their windows at the hardware store?

The statement is quite correct, there is no standard size. It certainly makes sense to order several windows of the same size, which can bring slight cost advantages. Above all, it looks better.

But for a normal new single-family house, there is no standard size and usually no hardware store products. Larger elements eventually become disproportionately expensive because installation is difficult. That is why there are often these 1.50 - 1.75 meter "wide" patio doors...

And again, when it comes to windows, there are countless variants, starting with the number of mushroom cams (8-12, depending on the size of the window, would be good), the color or laminated safety glass and special fittings, which e.g. cannot be drilled out and resist force from outside. Lockable fittings or fittings with push buttons. Flat thresholds at patio exits. Then don’t forget the gutter. RAL installation with sealing tapes is hopefully standard nowadays?

Or with electric blinds there are mechanical-electric ones (2 switches next to each other), electronic ones (short tap and they run to the end position), those with timers or further automation or a KNX solution.

Karsten had already written something like this once:
- Take white windows without extras from Poland
- no (!) blinds

and I don’t know if Karsten is also of the opinion, but here you can also save:
- no satellite dish, there is IPTV from Telekom anyway (or more and more households are completely giving up TV)
- WLAN instead of LAN
- fewer sockets, there are distributors and extension cords
- standard sanitary equipment
- IKEA kitchen with IKEA appliances; preferably kitchen separated, then cheap fronts can be used
- concrete roof tiles instead of clay roof tiles
- window rebate ventilation instead of ventilation system
etc. etc. etc.

Regarding resale, it depends on the location: in a good location you can really invest. In a less demanded location you can’t get everything back anyway.

Heating radiators definitely reduce the value disproportionately compared to underfloor heating nowadays. Definitely no one will appreciate your special tile taste either. But with tiles the extra costs are limited anyway. If you have to lay 25 sqm (bathroom floor and partly walls) and the tile costs 10 EUR more, then it is only 250 EUR extra cost.

Kitchen, bathroom, floor coverings, tiles, etc. are fittings and are mostly never fully priced in at resale. But things like circulation, underfloor heating, geothermal drilling, all components, clay roof tiles, electrical systems (as far as appropriate; no one pays KNX surcharges when buying existing buildings, but network and electric blinds/raffstores definitely increase the value of the house) etc. belong to the building fabric and definitely affect the price, as far as you sell or have to sell in a sought-after location.

Well, whether a craftsman’s botch job should be a reason to generally avoid built-in fittings is up to everyone to decide... for me, I see no causal connection with the built-in fitting itself. You yourself say it was poorly installed... so what?

In our neighbors’ rental building, the shower sealing was botched – the tenant below noticed it. So would the consequence be: no more showers installed and only "the very top floor" moved into? Seriously?

It’s already difficult when someone comes around swinging the naivety club and then offers something like that, right? [emoji6]

It is common to produce windows made to measure; that’s how everyone in the industry does it. Even what is made for bulk orders from hardware stores is made to measure—not according to some "fantasy dimension" of intermediate sizes, but according to common formats within the standard building dimension scale. Single-leaf 110 is common. And white without mustard and without onions.

Personally none. But contractors who have more than one customer like Karsten probably buy such windows more often.

What is a "normal" newly built single-family house? I also always think that only people who build 9 x 9 m witch houses with gable roofs buy that, and that they are almost extinct. But if you couldn’t sell that in volume, hardware stores wouldn’t take it into their assortment.

And as long as that is the case, I think it’s smart if economical builders check their building plans against building components in "standard sizes." As soon as you have special requests (like, for example, frame foiling), cookie-cutter ends even with stock sizes. "Standard" only works consistently or not at all.

I believe you! But: Wikipedia lists the base unit in the construction measure system as 12.5 cm (= 1 am) and explains that an opening size can be determined by adding another gap (+1 cm). In this context, I cannot recognize 110 cm as a meaningful standard size. More likely 113.5 cm.

However, I admit I have no idea about this... At our place, the house was glued together from sand-lime plan bricks (these huge things that practically formed a kit), so there was no relevant construction measure. That was also the answer from the "architect" (we bought from the developer) when I asked about "standard sizes" for windows. Most of ours have a rough opening size of 161 cm. Oh yes, our house was not cheap :-(.

I would write what you can get for under 1500/sqm but that would only cause frustration...

Another way to build cheaply is with a lot of own work and many individual trade tenders.

We are on the home stretch and there should be no more surprises now.

We built:
160 sqm "architect-designed" split-level house in settlement house style, nothing off the shelf.
Large window areas up to 12 sqm. Large roof window areas, e.g. filling the entire bathroom.
Just under KfW40 (officially 55), here the monolithic wall construction did not allow more.

Air-water heat pump with photovoltaics and underfloor heating
Controlled residential ventilation with geothermal exchanger, heat recovery and enthalpy exchanger

Electricity classic, but in scope corresponding to comfort equipment

Two bathrooms with upscale sanitary fittings (Grohe/Villeroy upper price segment), the larger bathroom has a sauna.

Except for children's/bedrooms everything tiled in concrete/wood look upper price segment (which you can normally get through the tiler)
Children's/bedrooms will have parquet

Fully automatic blinds on south/west windows, east windows constructively shaded.
Roof windows shaded manually.

Masonry fireplace, room air independent.

--------------
A list we gave early to the turnkey providers. The $ signs were blinking and after initial cost estimates we were always around 2.1-2.5 k€/m2, so 340k to 400k for the house.

At the current status we are at pretty much exactly 1500€/m² just for the cost groups 300 and 400.
