ᐅ Is a detached garage more cost-effective?

Hello,
I am just starting to plan my house build, and the garage is already on my mind.
I would like to have a garage with direct access to the house.
For this, the garage needs to be attached to the house, and it is clear that sealing between the house and garage will be more expensive than if the garage stands separately.
A passage between the house and garage would also be possible in that case.
What are your experiences with this?
Thanks,
Tom

That’s already what you’d call “putting the cart before the horse” ;-)

Have you ever driven with a trailer? … and now imagine if the trailer hitch wasn’t steerable. Attaching the house and garage directly like that can make positioning the house much more complicated, especially with bulky structures. What does your plot say about it—is the ground level at the gate and door well matched?

You need more square meters of living space if it is to be planned meaningfully in the floor plan.
Approximately €3,000 per square meter (about $3,300), so possibly around €15,000 (about $16,500) just for a more or less pointless entrance, allowing you to avoid using the main entrance with the expensive front door.
The garage would also need to be designed in size accordingly...

The garage will also be included when calculating the applicable area for distributing the development costs. The fire protection door is then negligible.

I have this kind of access, which I wouldn’t want to miss.

Are you planning the build yourself?

About 3,000€ per square meter (about $3,300), so possibly around 15,000€ (about $16,500) just for a more or less unnecessary access, so you don’t have to use the main entrance with the expensive front door.
And the garage would also have to be sized accordingly...

I see the idea of it being "unnecessary" very differently. We have an access door from the garage into the house, and it is used several times daily. This was one of our "must-have" features. For example, we keep our drinks in the garage, as well as all our tools. Without that access, I would have to open the garage door every time or go through the terrace to get into the garage.
Also, being able to enter the house directly from the car without having to unlock an additional door first is very convenient. We use the garage access at least as often as the front door.
And I think the 15,000€ figure is a bit exaggerated.
In our case, nothing at all would have changed in the floor plan except that the opening to the garage would have been closed.
So, we would have saved about 300€ (about $330) by not installing the steel door.

Well .. with a garage entrance, you usually end up creating a kind of second hallway in terms of space .. that’s what @ypg was getting at. ... and it reduces usable space (for example, for drinks or tools 😉 ) in the area where you enter the house from the garage.
