ᐅ Attaching a wooden workshop to the house

Hello,
We will soon have a timber frame house with insulation built.
I would like to build a workshop myself, also using timber frame construction, with a ventilated wooden cladding system. Since space is limited, it would be advantageous if the workshop could be partially attached to the house.
The workshop will not be built on a concrete slab but on a wooden floor raised about 20 cm (8 inches) above the ground, supported by pier foundations.
Now to my question: How should I connect or attach the workshop to the house so that the wood does not rot and the connection remains dry?
I would be very grateful for some advice.

Best regards,
Olaf

Now this is theoretical! You would need to know the construction of the exterior wall of the house (cross-section) and the heat pump planning. Otherwise, it is difficult to provide a reliable answer from a distance.

The construction of the exterior wall from inside to outside:
-160mm (6.3 inches) timber stud frame with insulation in between
-12.5mm (0.5 inches) gypsum fiberboard
-140mm (5.5 inches) insulation boards (expanded polystyrene rigid foam)
-6.5mm (0.26 inches) exterior render

I’m not sure about the requirements for building permits / planning permission.

Thanks for the note.

Ignoring this advice from @hampshire could make all other considerations pointless. You might take that risk when extending an older building, but for a new build? Maybe especially in a new development area?

Yes, heated basically sounds like an extension of living space.
That won’t be easily approved.

The architect designing our house is also handling the building application for the workshop/hobby room. During the preliminary design meeting, he made sure we comply with the building boundaries. That’s also why the workshop/hobby room is connected to the house. The workshop/hobby room could be positioned as a separate building, but then I would have to cut off a corner of it to stay within the building boundary and I would end up with a narrow passage of 1m (3 feet) between the house and the workshop.
