ᐅ Building a House with TuC and Modifications – Your Thoughts?

derkobiHello 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

The thicker brick is fine and cost-effective. Whether to choose a heat pump is a matter of personal preference; I don’t find those systems simple and robust enough. A gas heating system is not only fault-tolerant but also quite economical—you probably won’t save the 5000 by going without it, I bet. The 5000 refers to the cost saved by not having a gas connection.
The underfloor heating system is a nice option; I like it, especially if you choose suitable flooring, ideally glued tiles or vinyl.
The Porith stone is acceptable—its sound insulation is not the best, but its thermal insulation is very good. When plastering, make sure to finish with a silicone-based facade paint; this will keep it looking clean for a long time.
Good luck. K.

Thanks for the tips, that was really quick.
I’ve already read a lot about the issues and settings with heat pumps. The reason we still considered buying one were two statements suggesting you can get by with about €80 (approx. $88) in electricity per month.
I initially estimated the gas connection at around €2,500 (approx. $2,750), but I need to check that again.
An extra €6,000 (approx. $6,600) for the heat pump minus €2,500 (approx. $2,750) for the gas connection would have meant an additional €3,500 (approx. $3,850).
The question is, how much does gas cost roughly per month?
Then there would also be chimney sweeping fees, gas meter rental, and I’m not sure if anything else would be added.
We want to install vinyl flooring everywhere except in the bathrooms, hallway, and utility room, where we plan to use tiles. We just need to do some more research on whether vinyl is really as durable as claimed, especially since we also have a dog.
Good tip about the paint, saved that.

We are getting one too (also building with Town & Country).
