Experience reports air heat pump, wood stove, solar system, noises

If you only want a later room on the ground floor "just in case":
When we are older/if needed, we can section off the TV corner with a wall and then have an extra room on the ground floor.

Thanks for the tip. Could be a solution :)

Hello,

That means a single-family house with 1 1/2 floors, half-hipped roof - solid construction.
We now have a floor plan that we could work with (attached).
Our first and second biggest problems were that we want the large bathroom (with bathtub) on the ground floor as well as our bedroom.
This significantly increases the floor area.

I have some questions, especially because the budget is quite tight:

- why did you plan the space in front of the stairs as an entrance area and not as the start of the stairway? That way you would gain space on both floors. Otherwise I would do without it, as it produces unnecessary costs and “only” looks appealing.
- if the bedroom is only planned for old age, I would place the kitchen in the front and separate the room currently planned as kitchen from the living room later in old age - when the time comes and a stairlift is not an option.
- why is a shower bathroom on the ground floor not enough for you? According to all experience with disabilities, showers are by far the better wet cells; they just need to be planned barrier-free and larger.

- Underfloor heating is fixed, but which heating type? At the moment we are looking at an air heat pump, because geothermal energy is too expensive to install. A wood stove is also fixed as well as a small solar system. Can anyone share their experience with air heat pumps (noise, efficiency)?

You write in the other thread as if you have already decided on the air-to-water heat pump. If the property conditions are right, it would, according to all experience and the corresponding masonry construction, already be a KfW 70 efficiency house.

With a split unit, opinions differ, and it becomes apparent what the average German is best at. When someone talks about "possible" noises, they hear them too :( The outdoor units are all only allowed to reach certain decibel values, beyond that it is forbidden; simply put.

Our budget is 180,000 €. We have additionally planned 20,000 € as incidental costs. Is that realistic for the project? We already have offers, but always have the feeling of not being taken seriously.

With the overbuilt entrance area, this won’t work out, and a half-hipped roof is not one of the inexpensive solutions either.

When I read all this, it means for me either to reduce the house so much that it fits our budget or to increase the budget.

Not necessarily smaller. Do without the overbuilt entrance area and the half-hipped roof and it should be enough for the house; even as a KfW 70 efficiency house.

I have concerns with all providers, whether it was a company like Helma or an architect with construction supervision, etc.
How high should I go instead of 1500 so that at least a little room for maneuver remains?

Then you were unlucky with both in that the sellers or architect had not you but their own closing in mind.

If you don’t get any further in your search for the right building partner for you, just contact me; I can gladly try to help you.

Rhenish regards

Give up the built-upon WF and the clipped gable roof and it should be enough for the house; even as a KfW 70 efficiency house.

With 149 sqm (ok, minus WF) and a budget of 180,000 euros? As a KfW70?

Maybe also give up the bay window, the air heat pump, and the fireplace...

Hello everyone,

thank you very much for the opinions and suggestions. I have taken everything to heart and thought about our little house again. The result was that we completely redesigned it. Next week we have another appointment with a construction company. Therefore, I am not yet quite sure if everything is statically okay, as we drew the plan ourselves. Nevertheless, I would like to ask for your opinions once again beforehand.
Whether with or without Kfw 70 has not yet been decided, but the heating is now set to be an air/water heat pump with solar support. I hope that our price/cost expectations are at least somewhat realistic now.

As I said, I would be grateful for a few opinions.

Utility/technical room larger, therefore the bathroom on the ground floor can be smaller. Move wardrobe wall direction sleep so that the long wall for cabinets is also usable (bedroom is sufficient with 12 sqm). At the moment you have a dead long wall in the wardrobe that cannot be used. Is a catalog floor plan, right?

The shower bathroom on the ground floor immediately caught my eye. It only contains a sink, toilet, and shower. You don’t need nearly 10 sqm for that. At first, I thought you could add some space to the living room, but ypg is right. You also need storage space. Therefore, you should reduce the size of the shower bathroom and add that to the utility room. Keep in mind – the utility room contains the heat pump technology as well as (if I understood correctly) the domestic hot water tank for [XXX liters of water]. Additionally, there is the electrical panel. There isn’t much space left to store anything else (possibly another case of water :) ).
