ᐅ Integrate masonry (privacy wall) with the facade

Hello dear homebuilding team,

I have purchased a semi-detached house and would like to build a partition wall between the terraces. It should be about 9 meters (30 feet) long and slope down from approximately 2.80 meters (9 feet) to the property boundary.
My question is:
Do I need to remove the exterior insulation boards, or can I connect the wall directly to the insulation, which I would prefer? The wall thickness will be between 26 and 30 cm (10 to 12 inches).
I appreciate any advice.

Kind regards

I wouldn’t connect that at all but leave an air gap.

However, as far as I know, you are not allowed to build a 2.80-meter (9 feet 2 inches) high wall directly on the property line.

Definitely do not remove the insulation panels. Doing so will create a significant thermal bridge!

I completely agree with hbf12.

Leave a small gap towards the house, which you can possibly screen with a plant to provide privacy.

However, please make sure to check the local regulations regarding boundary construction beforehand—I also doubt that a wall up to 2.80 m (9 feet) high is allowed directly on the property line.

Best regards,

Dirk

We don’t know in which country abroad you bought the property, but I do know that in Germany, such a boundary structure of this length and height would not be approved. Therefore – and if you haven’t done so already – please clarify beforehand what height and length are allowed for such a boundary wall.

Always keep the system intact and place the masonry in front of the insulation.

To be completely precise and thorough:

In most states or municipal regulations, building a boundary wall up to 1.8m or 2m (6 or 6.5 feet) high is generally permitted without a building permit / planning permission. Depending on further provisions, however, it is possible to obtain permission for a wall up to 2.8m (9 feet) high, for example through neighbor approval and/or registering a building encumbrance.

It is also the case that a neighbor must promptly object to a wall that is too high. If you build the wall 2.8m (9 feet) high and the neighbor only raises concerns three years later because they think the wall is too tall, their objections may no longer be valid.

Therefore, you should discuss the height with your neighbor and the building authority beforehand to see if it is possible.

Kind regards,
