Garage immediately next to the house wall, any experiences?

If the intention is to accommodate bicycles in the upper part of the plan, then this should be examined carefully, including the path to this storage area if there are 2 cars parked there.

Outside length 850, so presumably max. 800 cm inside length remains. For today's cars, one should plan about 600 cm so that there is still room to move around. Then only such a narrow entrance to the bicycle area, this should be tested to see how it works best.

Hello, thank you very much for the answer. The garage is 650 mm wide. My wife drives a small car. In my opinion, that should fit.

I don't know the depth of the platform at the moment because it's still hard to imagine everything.

Then just walk through a residential area and see what kind of platforms people have. If you ask nicely, you will sometimes be allowed to take a closer look at a platform in detail. Afterwards, have your desired platform drawn into the plan with the exact measurements. Then you'll see if it fits.

The garage is 650 mm wide. My wife drives a small car. In my opinion, that should be fine.

Just draw the second car to scale and consider how to get through the garage door (the first car is also crucial for that) and then simulate the path between the cars to the door and then parking the bicycles. It has to be practical and quick, otherwise the bikes will pile up everywhere except in the extension.

We have already implemented this similarly (slightly smaller). I would now advise you to build the garage with its own walls and not to extend the floor slab of the house. It is better to consider the garage and the house as separate building structures. Although it is somewhat more expensive, it has a few advantages: Noise decoupling – structure-borne sound (garage door opening/closing not heard inside the house) Settlement cracks between house and garage are avoided Energy loss (albeit small) through thermal bridging (despite [Isokorb]) is excluded We do not have a platform in front of the front door because we built barrier-free. The driveway is also only about 4m wide. In the old house, we had 6 steps to the ground floor, and the bottom step was already quite worn from the many contacts with tires, etc. The driveway there was about 5m wide. And if you parked too close, the door swing area was dangerously close to the stair steps.
