House Design
Planner: combination of builder and self-designed
What do you particularly like? Why? We are very satisfied with the upper floor, especially regarding the room layout and sizes. An L-shape for the living-dining area on the ground floor is preferred.
What do you dislike? Why? I am still uncertain about the ground floor because the study is also intended as a guest room; it seems a bit small for that purpose, although a 1.40m (55 inch) pull-out couch would likely fit.
Cost estimate according to architect/planner: 275,000
Personal budget limit for the house, including equipment: 300,000
Preferred heating technology: air-to-water heat pump or ground-source heat pump

If you had to give up something, on which details/upgrades
- could you do without:
- could you not do without: staircase not directly at the front door, ground floor shower

Why is the design as it is now? For example:
We have visited many model homes and construction companies, sought advice, and usually returned to a floor plan like this because we wanted an additional guest/office room on the ground floor. We saw the upper floor almost exactly as drawn in a model home and only enlarged the bathroom slightly and shifted the dressing room a little.

So, I hope I’ve filled in the most important details first. I am open to any changes; as mentioned, the L-shape in the living-dining area should be maintained.
What still concerns me somewhat is the placement of the possible outdoor unit for the air-to-water heat pump, which according to the development plan must be at least 10m (33 feet) from the nearest neighbor; with the current plan it would be directly in front of the house or beside the carport.
After a long selection process and several offers, we are currently favoring Gussek Haus, Helma, and Elbe-Haus, which could realize the house roughly within the budget. The tendency currently leans towards Gussek Haus because although it is a prefab house, we like the hybrid wall and the clinker brick exterior well, and the price-performance ratio fits. But nothing is decided yet; the plot will be developed at the beginning of next year and construction will start from summer 2021.

Floor plan of a house: living/dining, kitchen, hallway, office, utility room and shower/WC.


Upper floor plan: bedroom, dressing room, 2 children's rooms, corridor, bathroom, storage room, staircase

The question is how often you walk down the stairs barefoot.

Sure, every day in your own house.
With taller sand-lime brick walls, you can also use the knee wall with a strip window.

To revisit the idea of a house that is more elongated and oriented towards the back, we are considering installing a photovoltaic system on the roof, either now or later. However, since the roof would have an east-west orientation, the system might not be as efficient. Would it still be worthwhile? Or would it be better to install it on the garage roof instead?

We were told that an east-west orientation is actually better. On the one hand, you can install panels on both sides (which is also possible with north, but not as efficient). On the other hand, energy production increases during the times when people are usually at home, namely in the morning and evening.

.. so with our triple-glazed windows, you can only see inside when it is dark outside and the house is lit; under normal daylight conditions, you have to be standing right in front of the glass to see inside.

On the one hand, that is a separate topic in itself, but on the other hand, the main focus should remain on the house itself, meaning you should not optimize the house based on the photovoltaic system. We are not located in a tropical climate where a few panels on the roof would make the building self-sufficient anyway.

...in my opinion, all of this should be absolutely secondary. If you try to include it already in the floor plan design, you might end up making compromises, and the floor plan should have as few compromises as possible. I think you can always find a way to install photovoltaics later—the usability of the house must take absolute priority!
