Hello construction experts and enthusiasts, I have been reading along for a while and now I need some advice.

We want to build with TuC here in Saxony, postal code area 02.
The companies that build for TuC here have a good reputation and there is a lot of building activity at the moment.

Most people simply build an affordable house, called Standard eco Baustein 1. Unfortunately, posting links is not allowed. We want to make a few small changes if they make sense.

We would like to increase the exterior wall thickness from 24cm (9.5 inches) to 36.5cm (14 inches), using aerated concrete from Porit in monolithic construction.
The additional cost is about 7,300€ (the foundation slab will also be larger to maintain the living space). The rest will be adjusted to the stronger walls – roof, windowsills, etc.

If worthwhile, we would replace the gas condensing boiler with an air-to-water heat pump (Vaillant aroTherm Split vwl 75/5) with Unitower vwl 78/5 IS.
Additional cost: 6,000€.

Underfloor heating throughout the house.
The house model is Flair 125, where 125 stands for the square meters.
One and a half stories.

What are your thoughts on this?

Kind regards,
Kobi

I have also read statements like these quite often, so I think there will only be something in the bathroom.

May I ask how the selection process went? What was the flat fee for selections according to the scope of work, and how much extra do requested changes typically cost?

I'm not involved in that yet; we're not that far along. On Friday, there is the notary appointment for the land, followed by a meeting at TuC regarding the floor plan and so on.

What do you mean by selection flat rate?
I found the additional costs reasonable, in some cases even surprisingly low (for example, upgrading from a small guest bathroom sink to a standard-sized sink only cost about €3.50 or something around that).
The process was that for some items (like interior doors and bathroom fixtures), we went directly to the suppliers from whom the products would be sourced and made our selections there. For other items (window sills and such), the selections were made at the model home of our franchisee, using sample cards and pieces.
