Build a windbreak - wood? What dimensions?

Hello everyone,

I want to add a windbreak to my existing house.
It should become a windbreak. The rear part will be fitted with a fixed window element.
The question is whether I should ideally build the side panel with masonry or if it should be made of wood. The same applies to the front where the door is to be installed.

The existing door is 1140 mm wide. An already existing doorbell system must be installed to the right of the door and requires 200 mm of space including clearance on the right and left, i.e., without clearance for the door, there would only be 100 mm of space on the left side for the sidewall without letting the beam protrude on the side.
A picture of the conditions is also attached.

The outermost, cantilevered load point can also be easily supported by tie rods, which will be led inward into the masonry and anchored from inside the house.
The stairwell is currently still in shell construction anyway.

On the outside, the windbreak should be completely clad with rhombus slats. The cover with slope and eaves flashing will of course also be taken into account accordingly.

If wood, then what dimensions of the wood? Type of wood: laminated timber or dimensional lumber? Dovetailed or are angle brackets / joist hangers sufficient?

If the sidewall is to be built with masonry, which bricks and what wall thickness do I need at minimum?

Thank you in advance for your help.

Best regards

As a contrast to the facade in Siberian larch. You could also leave it untreated; it will weather to a silvery gray. Pay attention to tight growth rings, don’t let anyone sell you local wood, it grows too fast. Finnish is also good.

Do you actually need a permit for something like that?
Playing with a similar idea.

Yes, I definitely wanted to clad it with Siberian larch.

I’m toying with a similar idea.

I haven’t dealt with it yet but I can’t imagine you would need one for such a small thing.

Yes, sometimes it's better not to ask at all. It's housing after all, so I can't imagine that it's 'officially' just allowed like that.

Whether this is exempt from approval depends on the respective state building code. I don't know them all, but in most federal states this is the case. Important is that it is unheated and that the distance regulations are observed and, if applicable, a development plan and floor area ratio and plot ratio.

The height in the drawing may not be correct. 1550mm? More likely 2550mm.

For DIY, I would definitely recommend wood. You only need three point foundations with post anchors (at the corners and at the door hinge). Anchoring the masonry wall to the house wall and the remaining wooden structure and making the foundation adjoining the house is much more work and offers no added value.

KVH (timber graded for structural use) is completely sufficient for the span as wood. I will not recommend dimensions. Take the example of patio roofs or carport kits.

You can usually use larch for wood, including the posts and beams; it is not more expensive than pine/spruce. Whether it is Siberian, Finnish, Austrian, or even local is completely irrelevant for durability! Durability is ensured first by structural wood protection and second by the natural protection of larch against fungal growth. Whether the wood is hard or not doesn't matter much for water and fungus.

The anchoring in the house wall depends on the masonry and insulation. Alternatively, you could also set posts on the house wall and just lean against the house wall.
