Dear experts and readers,
We are considering the purchase of a newly built semi-detached house, scheduled for completion early next year. Since we are novices in this field, I wanted to ask the community whether 30cm (12 inches) T8 bricks (WLG08) combined with an air-to-air heat pump make sense.
From my initial research, this does not seem optimal regarding insulation and the expected electricity costs.
Thicker bricks might be possible, but the living area is already quite limited (approximately 7.5 x 8 meters (25 x 26 feet) footprint). I am also leaning more towards a gas boiler (proven technology?). The basement has 24cm (9.5 inches) waterproof concrete and 10cm (4 inches) thermal insulation.
The partition wall to the neighbor is only made of 2 x 15cm (2 x 6 inches) sand-lime bricks (including party wall panels). Is this sufficient for "standard" soundproofing?
I appreciate any feedback.

Sorry! According to the building specifications, it is a 30cm (12 inches) T8 brick with an air-to-water heat pump.
The question of whether this combination makes sense still remains.
I would really appreciate your opinion on this. According to the architect, this can already achieve KfW 55 standard.
