Good evening everyone

I’m starting a small collection thread here for photos and progress updates on our second building project.
We’ve already moved to the Palatinate region to be closer to the construction site. Now we’re watching eagerly and happily as our (hopefully final) dream home takes shape near family.

One big challenge still ahead of us is the facade design. I really love the Nordic style with brickwork and mullioned windows. That won’t be possible here for two reasons: firstly, no one here can do bricklaying, and secondly, it would stand out too much. We will be going with a rendered facade. How to design the colors of the facade and windows to still create some country house / cottage charm is currently still a work in progress mentally.

Otherwise, I’m sharing our plans here and how it will eventually be built.
The support pillar marked near the kitchen island could be removed for a small extra cost, so that will be gone.

The room for “garden equipment” under the garage will get a partition wall for structural reasons.
It won’t be fully finished living space like in the house, but underfloor heating will be installed, along with a lockable door and a window. It’s meant to store garden tools but also some of the building services equipment, since the utility room (HAR) is quite small, and maybe be used as a party room.

We had three construction companies in the final selection. In the end, we chose the “doer” – a builder recommended to us here by friends and family. No website, no smartphone, but he is on site every day himself working in overalls. He has a very good reputation in this area and now rarely builds single-family homes. We were a bit lucky through personal connections and a very friendly initial phone call to get our foot in the door. So far we are very satisfied with this choice.

I’m surprised that all the pipes are exposed. Our heating engineer insulated everything.

Buffers were necessary in the past with on/off heat pumps. You could heat up the buffer, and it would then release the heat gradually over time.

Today, you generally have modulating heat pumps that deliver exactly the supply temperature required. The screed then acts as the storage.

Buffers are usually only mandated by manufacturers to prevent the pump from running dry during defrost cycles or in closed heating circuits caused by the differential pressure controller (DPC).

If you deactivate the DPC and keep all heating circuits open at all times, that is sufficient.

In that case, the buffer is simply extra water that needs to be heated and partially releases its heat where it is not needed (in the heating system room).

Insulation will definitely be added later.

The next time I see the builder/plumber, I’ll ask about the purpose of the buffer tank. They must have had a reason for it.

In the meantime, we’ve just received quotes from the electrician for the photovoltaic system, wallbox, and related equipment.

For 12.45 kWp, the price is €19,100 (about $), and with a 12.8 kWh (kilowatt-hour) battery storage, it’s €25,560 (about $). Fully installed and connected.
The price per kWp is therefore €1,550, and the storage costs €7,800 for 12.8 kWh. He also applied a €1,000 discount for the combined offer, plus there’s an additional discount if you pay 50% upfront.

Overall, this is somewhat above the budget we had initially planned for the photovoltaic system. On the other hand, we find the offer financially attractive. So we’re considering borrowing the money from our savings. This might mean parking the car in a garage without a door, but with battery storage. 😀 We might not have enough left for the garage door after all.

The gate can be installed later. The price for the photovoltaic system is acceptable.

It’s probably not finished yet.

I would also suggest skipping the garage door for now; you can probably add it later without much trouble (wasn’t that the original idea anyway?). Instead, you can install solar panels on it right away. If it still fits your budget, that would be my first choice.

Until then, you will just have a masonry carport. 😎

Yes, it would just barely fit. However, this means we have to be quite strict, so nothing else can really change.

On the other hand, investing in photovoltaic panels with battery storage would likely pay off significantly given our consumption profile. Next week, we will switch to electric vehicles, work exclusively from home, and have air conditioning as well as a heat pump. We use a lot of electricity. In our old house, we had 4.55 kWp on the roof and always wished for more capacity. Back then, we usually consumed over 60% of the generated power ourselves, and that was without storage.
