ᐅ Facade insulation on a semi-detached house: what and how approval from neighbors is required

Hello dear forum members,
I have some questions regarding the renovation of my semi-detached house that I am planning and hope you can assist me with.
I want to have my semi-detached house insulated according to KfW standards.
According to the declaration of division, the two semi-detached units are completely separate from a legal point of view.
However, in my case, the roof needs to be extended by about 2 to 3 rows of tiles so that the insulation is also protected from above.
At the same time, the roof gutter between my property and my neighbor’s must be adjusted so that rainwater can continue to drain properly.
Additionally, the plasterer recommends installing insulation extending slightly (about 50cm (20 inches)) beyond my property boundary onto the neighbor’s side to avoid thermal bridging.
In which cases do I need my neighbor’s permission? What should such permission look like?
Is there a template letter available in this forum that I could use as a guide for wording?
Thank you in advance for your possible answers.
Thanks

The insulation, including the roof extension, costs 21,000.
Heating costs are currently 1,300 € per year. Wow, 1,300 is quite a sum. But even with this extreme heating demand, the investment would only pay off after about 35–40 years. (Even longer if that includes hot water.) I would think carefully about that and not let an insulation salesman make it look better than it really is.
The roof and windows are already new, I assume? If not, maybe start there first.

As mentioned before, maybe just insulate the roof, check the windows, and look for thermal bridges—especially around old roller shutter boxes.
How is the heating done?
I would consider installing a photovoltaic system on the roof first. Depending on self-consumption, the return on investment is between 8 to 10 years.

Deliverer9 Apr 2018 12:28If you want to sell and/or the facade needs to be renovated anyway... it might make sense, yes. But energy costs NEVER cut in half just by adding facade insulation. I’ve already considered a very generous 40%. In the end, it’s probably closer to 25%.
However, I don’t know how high the funding is. What are the typical figures?

Just out of curiosity:
How old is the house?
Annual heating costs of 1300 euros are not much when you compare them to figures from older houses.
Roughly estimated, this would correspond to expenses of around 800 € per year.
The base price will not decrease either.
However, if I had 21,000 euros available and planned to enjoy the house for another 50 years, I would also go ahead with the insulation.
I only know that setbacks from property boundaries smaller than 3 meters (10 feet) can be waived retroactively if energy-efficient refurbishment is carried out. In such cases, the positive effect takes precedence over the fixed 3-meter (10-foot) requirement.

I don’t know how much the subsidy is. What are the figures?The original poster wrote that the insulation will be done according to KfW standards. This means they are upgrading the existing building to the KfW 55 energy efficiency level of a new build. Halving heating costs can therefore be expected, but the exact forecast should be provided by the involved energy consultant.
The subsidy covers 30% of the costs up to a total of €30,000 (approximately $32,000). There may also be additional grants for a new heating system, etc.
You also have to compare these costs to planned roof or facade renovations anyway. I think a return on investment (ROI) of 15–20 years is achievable, which, in my opinion, is a reasonable return.
