ᐅ Floor plan design shortly before submitting the building permit application

Hello everyone!

As some users have requested before, I’m now starting a new thread with the current planning of our detached house, which is about to be finalized.

These are the preliminary drawings for the building permit / planning permission application, and I have one last chance to review them and point out any issues.

It still seems to me that there is less than 1.20m (4 feet) of space between the two wardrobes in the dressing room. Or am I seeing this wrong? Apparently, the rooms on the left and right were overlooked and not adjusted accordingly.

Two Velux ceiling spotlights are still planned to illuminate the upper floor hallway.

In the basement, on the right side in the upper room, a window similar to the one on the left basement side is an option.

We still haven’t decided on the T30 fire-rated door to the garage, even though it is shown in the plans. Most likely, for safety reasons and the limited use of the kitchen at the other end of the house, we will eventually forgo it.

User 11ant pointed out that the right window in child’s room 2 is suboptimally positioned. However, this could still be changed after submitting the building permit / planning permission application. Our architect thinks moving the window to the left would negatively affect the house’s exterior appearance. We’ll have to see about that.

The heating load calculation is now available. However, it seems to be based on a stage before the 41m³ (1450 ft³) volume was reduced. Is the reduction significant enough to require a new calculation, or does it not really make much difference overall?

I suspect it will have to be redone anyway, since the building authority also requires this proof.

Oh, I just saw your attachments. These are data from the geological survey.
It really looks pretty poor; you can forget about using a probe there. Even if you weren’t limited to a depth of 30 meters (98 feet), it would still be an unreasonably deep and therefore expensive borehole.

The specialist company said that surface collectors are an alternative. Apparently, geothermal energy is sufficient for these. However, I don’t feel comfortable with that option. The builder also mentioned that he has never seen a project where this was actually installed in the end.

At the moment, many factors favor a gas heating system. Supposedly, the mandatory solar component required by the Energy Saving Ordinance 2016 can be waived if you purchase a certain percentage of biogas and cover the ecological requirements that way. But how do you prove in the long term that you are always subscribing to tariffs with the corresponding biogas share? Submitting your bill to the authorities every year? If this is actually possible, we would prefer it a thousand times over to an air source heat pump or surface collectors.

How much would the price difference be between geothermal energy and gas for the general contractor (GC)?

Is a mechanical ventilation system with heat recovery planned?

As far as I know, it doesn’t work like that. Biogas actually has to flow through the pipeline. You can only achieve that if, to put it simply, your neighbor is a farmer with a biogas plant and you can connect to it. A controlled mechanical ventilation with heat recovery system would be recommended here. More expensive than solar thermal, but it comes with benefits.

Yes, controlled residential ventilation is planned.

Gas would be €5,214 (about $5,700) cheaper. Even with the solar collector system included. I would need to inquire about the cost without solar if the biogas option is feasible.

EDIT:
I don’t think the biogas option will work.

"Only if the biogas is produced nearby, for example in a biogas plant next door, is the biogas rated with a Primary Energy Factor (PEF) of 0.5. Since biomethane is usually delivered to customers via the regular natural gas network, it has no impact on the calculation of the primary energy demand within the framework of the energy saving ordinance."
