Best way to mount a floating L-shaped desk to a brick wall

brickdeskmounting

I'm in the planning stages of building a new corner desk. I've started by measuring the corner of the room and planning the size, but I'm not sure what's the best way to mount it right now..

These are some sketchup renders of walls, desk, pc, monitors: Sketchup render enter image description here

Desk details

  • Width of L two legs: 60cm (23.622")

  • length of L the two legs: 272cm and 162cm (107" and 63")

  • material of the desk: 3 to 6 cm of plywood (1" to 2.5")

  • monitors will be wall-mounted

Another way of building the desk is using 1cm (or 1.5cm) pipe (round or square, not sure yet), and place a 1.5cm layer of plywood over that.

Mounting surface details:

  • the walls are brick (around 30cm / 11.8") with some hollow spaces in them

  • the corner behind the monitors is a load-bearing, concrete with rebar
    (hope that is the right term of concrete with huge steel beams in it)

  • the right wall has a window with an inside ledge

  • above the window is also a load-bearing beam made of concrete with
    rebar

I was thinking of mounting two pieces of wood or metal to the walls, to create a lip the desk can rest on and a few L-shaped metal pieces that will hold the desk and prevent it from warping.

Am I on the right track?
Thank you!

Reading from other comments here - 1cm round or 1cm square pipe just sticking straight out of the wall on its own will not cut the mustard. You should be thinking of some type of right angle support bracket. With a 60cm side shelf, supported along the wall on a solidly mounted strip, that right angle bracket should come out under the shelf to at least 50cm and have a vertical side against the wall as far down as feasible. I would think that the vertical span of the bracket should be at least 20cm. The length of the third side of the triangular bracket would best be if it was full length but if the vertical and horizontal sides of the bracket were really sturdy then the angled side could be shorter.

Brackets like this could be purchased ready made or fabricated out of wood or metal.

Note that with brackets like this a good share of downward applied force at the outer edge of the shelf will get translated to pull out force on the mounting strip and the upper fasteners on the bracket edge against the wall. You will have to make sure to use fasteners into the brick that can withstand this pullout force with a good margin of safety to ensure that the shelf is secure. You should definitely be thinking in terms of someone coming along and trying to sit on the edge of the desk even is that is never the intention.
