Costs for a single-family house in the northern area of Berlin

Hello,

I have now obtained several offers from developers. These are all on average about €1200-1300 per m² for a city villa including planning services for a KfW 70 house with medium specifications. This roughly matches the figures from my colleague.

The Berlin surrounding area is (still) cheaper than, for example, the rest of the country. Therefore, it decisively depends on the providers you requested and what is included in the €1,200.00/1,300.00 per sqm/Living space.

How and where can I find out – that is, have calculated – whether investing in a KFW70/KFW50 or KFW40 house is worthwhile at all in the next 10-20 years because of energy savings –

Only by having various scenarios calculated, for example by a technical building services planner. However, I strongly doubt that everything in solid construction from KfW 55 upwards will amortize before the technology fails.

Or whether it is better to build normally according to the minimum requirements of the Energy Saving Ordinance 2009 – but in such a way that later modernization can be done with less technical effort.

No. If you want to build strictly according to the Energy Saving Ordinance, I would at least make sure that the building envelope is suitable for KfW 70; you cannot just retrofit that easily.

Rhenish regards

Only by having various variations calculated, for example by a TGA planner. Although I strongly doubt that everything in solid construction from KfW 55 will pay off before the technology has given up the ghost.

Do you happen to know a good TGA in the northern area of Berlin???

No. If you want to build purely according to the Energy Saving Ordinance, I would at least make sure that the building envelope is suitable for KfW 70; you can't just retrofit that

My plan is to invest the money in the building envelope first. Depending on the conditions of the plot regarding the connection costs for gas, then possibly an air heat pump with supply and exhaust ventilation or a normal gas boiler with supply and exhaust ventilation.

I have also attached a representation here. I tend towards implementing insulation between KFW70 and 55. Now I just need to know what the additional costs are. Also, whether it is better to build monolithically or with Ytong + Multiflor???

Hello,

Do you happen to know a good MEP in the northern Berlin area???

By chance
