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

What changes did you make to the window sills? Are they all stone or granite or something like that?

No, just the color

Hello, can someone tell me if the partition walls (plasterboard) on the upper floor with insulation are constructed with a single or double layer of plasterboard? If it’s single, should we consider double-layering? Possibly to have something more secure to attach things to as well. Or is a single layer sufficient? The drawing shows walls about 10 cm (4 inches) thick.

Best regards,
Kobi

Unfortunately, I can’t provide any information on that. We are building a two-story house, and the walls on the upper floor are also made of aerated concrete.

Once sheathed, this is the basic standard; double sheathing with the green boards is only done in areas that will be tiled.
I didn’t build with Town & Country, but with a somewhat more expensive and higher-quality builder. They use this as the standard for the attic. It should be similar with Town & Country. Double sheathing is then considered an optional feature — we had it done on two walls, but ordered directly through the drywall contractor.

Double glazing definitely makes sense! We only paid a few hundred euros extra for the entire upper floor.

However, the improved sound insulation is partly offset by the ventilation gaps under the doors, which are necessary for the ventilation system. Just for your information.

Okay, this will probably be standard, and we need to apply something on top and consider it twice.

Thank you all, and have a nice Friday.

Best regards,
