Our garden is currently being extensively dug up. Around the house, a wooden walkway is being constructed that will align with the edging stones. In front of the wooden walkway, I would like to install or have installed an open pergola.
It should have an open top, possibly like in the photo with an open wooden slat roof. The supports will be attached to a steel beam on the house, where the awning is currently mounted. In the ground, I have had five foundation tubes embedded at a depth of 1 meter (3.3 feet).
At first, it was not entirely clear whether the pergola would be made of wood or steel, so I have not yet filled the tubes. If made of wood, the support would be embedded directly in concrete. Now, I tend to go with steel profiles, powder-coated anthracite, probably about 80 x 40 millimeters (3.1 x 1.6 inches) — similar to the image.
I would then have these made with a base plate so they can be bolted to the foundations.
Should the foundation tubes be completely filled, then drilled for holes, and the base plates anchored afterwards, or are there concerns with this approach?
The structure is open, not expected to bear significant loads — the wooden slats on the top would presumably be made of thermally modified wood, 5 cm x 2 cm (2 x 0.8 inches).
Thank you in advance.
Best regards
