New single-family house - Join us on this journey!

A lot has happened here during my absence. Exciting discussions about the EinMalEins :)

We are also calculating with 4k per sqm.

Good to know that you started with a similar benchmark here.

Photovoltaics: 45k (just a rough budget, nothing planned)

Uff, that is quite high compared to my calculation. Let's see how the first offers look a bit later.

Lighting planning and lighting (I wouldn’t want to do without that, it’s more important to us than furniture)

Yes, lighting planning is quite a topic. In my equipment and furniture costs, I have already included a certain lighting budget.
In general, I plan to involve a capable system integrator during my planning phase who will take a closer look at KNX and lighting with me.
Additionally, I will soon hire an energy consultant.

Technical planning HLS
Technical planning electrical

I already have the electrical planner on board.

Strange explanation. For us it was always: we have everything. We move in with that, and if the wardrobe can no longer be assembled, a new one is bought. The gaps in the bigger home are filled over months/years with enthusiasm and passion.
Or does your "22" in the name refer to your age? ...that you don’t own anything yet?

Maybe strange, but still understandable to me.
No, I am 22 years old and yes, I already own possessions. However, I am moving from a significantly smaller apartment and will not take all pieces of furniture with me. That’s why I consider it meaningful to make assumptions early on.

Of course, the new furniture will not be in the house and assembled on day 1. It will be a gradual process. It is already important to me that enough budget remains reserved.

At 4000/sqm, you can build a 65sqm granny flat and a main house of 285sqm.

Thanks for the counter calculation. Can you confirm that in the m2 calculation you are referring not to living area but to living & ancillary areas?
If it were pure living area, I would agree with you. But since we are calculating with WNFL-m2, we cannot fully accommodate our room concept within this total size.

For the photovoltaics, I would still plan 10k € for the pool. We ordered a large storage tank to heat the pool and are now around 40k €.

Lighting consultation and planning also cost something in such a project – easily 15-20k € if you want nice spots and lamps (not the 11 EUR spots from the hardware store).

I am curious what kind of overall offer my electrical planner will make. For him, it will be quite a large project with KNX & lighting, so there might be some small leeway – we’ll see.

I also think that around 4k € per sqm could fit well. Except for painting inside and outside, we have now assigned everything and end up at about 3,400.
Northern Bavaria, 220 sqm, a few extras like controlled residential ventilation, open space, large dormer.
At least these three extras you mentioned should already be included in the 4k.

Except for controlled residential ventilation, I am confident the extras will be included. When I look at the references of our architect, part of the surcharge certainly also goes into the fancy exterior design.

Whereas geothermal drilling has a large range.
And I think with such a large building, ventilation with air conditioning might also possibly become more expensive.
So better to plan a bit more than to have too little later.
I think in total your estimate is fine, even if some items might be a bit higher, others are already set very high so that it should more or less balance out. Unless something crazy happens again at the material markets, which is by no means unlikely when looking at the last three years.

Alright – thanks to you!

In the current floor plan you have 40 sqm for sleeping/dressing + a 25.04 sqm guest room. If you make the bedroom smaller and eliminate the 25 sqm room, you have room for 2 offices, right?

I am very curious about the result the architect will come up with here.

Yes, lighting design is such a topic. I have already factored in a certain lighting budget in my equipment and furniture costs. In general, I plan to involve a capable system integrator during my planning phase who will look more closely at KNX and lighting with me. Additionally, I will soon engage an energy consultant.

I meant lighting design more in terms of the interior architectural aspect... Our architect, for example, proposed from the beginning to design the lighting in such a way that the outdoor area/terrace is included, so that in the evening you are not looking at a black pane (if you want to have the outside light on for energy reasons)... also a lot of indirect light. The KNX guy will then implement this but will not plan the lighting for us.

Understood. Thanks to you! I will address this with the architect during the planning steps.
