Construction costs are currently skyrocketing

We were given 70-90 per spot. We are also currently considering where to place which. Bathroom / WC probably, dressing room, a few in the kitchen (there will be other lamps over the island), and maybe in the living room, but I’m still unsure about that.

We were initially set on recessed spotlights but then deviated and now have none at all. A minimalist surface-mounted spotlight will go in the shower, the bathroom will get a multiple ceiling spotlight, the guest WC will have a lamp with three individual lights hanging from the ceiling (one for the WC, two for the sinks), the hallway will have three Ikea Nymane sets of three ceiling spotlights, the kitchen island and adjacent table will get a track system with four spots and two pendant lights, the living room the same, the remaining rooms simple ceiling lamps, the bedroom has no ceiling lamp but only closet lighting and bedside lamps. Here and there ambient lighting will sneak in.

A Halox box with cable inside (Spot montiere ich) costs €129. A cable from the ceiling for a surface-mounted spot (montiere ich) costs €38... As said, kitchen, hallway ground floor and bathroom (T-Aufteilung) should have spots installed

We have recessed spotlights in the hallways and bathrooms. Cost: €85 net in concrete ceilings, €44 net in drywall ceilings, each without light bulbs. Sounds fair to me.

A HaloX box with cable inside (I install the spot) costs 129€.

A cable from the ceiling for a surface-mounted spot (I install) costs 38€...

As I said, kitchen, hallway ground floor and bathroom (T-distribution) should have spots

Are the larger HaloX housings (180mm) included as standard?
Then you can better align the escape route later with a line laser.
Such a rough ceiling tends to shift by 5-10mm ;)
The 180mm ones cost hardly more, I also took 3x 250mm for ceiling-integrated speakers for the kitchen, dining area and bathroom.
Or you hang the entire ceiling later, e.g. with a stretch ceiling.
PS: back then I bought the spots online and brought them directly to the concrete plant for the fine ceiling, that was cheaper than a flat rate.
But I laid the electrical wiring again in EL - when building with a general contractor you can often only say yes or no

With us also 85 euros/piece gross in filigree ceiling. We have spots in the hallways, bathrooms, as "additional lighting" behind the rows of chairs at the dining table and in the living room. Mostly dimmable. To me, they are coming off much too badly here in the thread.
