How to build a floating study desk?

[Jithesh]

I have a study nook with dimensions 2050mm wide and 550mm deep. I want to build a floating study desk on this area with some floating shelves above it extending the full width of the nook. The desk will be 45cm or 50cm deep (I don't want to use the full depth and want to leave some space to push the chair). I plan to use some timber cleats on the sides (using offcuts) and 6 floating shelf brackets attached to the back wall. The desk will be made of SpecRite 2400 x 900 x 33mm Brown Acacia Multi-Use Timber Panel, and offcuts to be used for top shelves. Will the cleats and floating brackets (31cm deep) provide enough support to the desk? Do I need a centre support (I want to avoid it for looks but don't want to take any risks)

I can't promise some sagging, even though depth is quite shallow @Jithesh 

So, in avoiding any stayed brackets or leg, would be to use 20-25mm square steel tube along the front edge resting in rebates in the side battens. The tube could be covered by a timber trim running along the front end of the desk.

Hi @Nailbag . How would you secure the steel rods against the desk board? Use an angke bracket or just let the board rest on it? Also would you recommend angle brackets to secure the desk against the side and back battens or screw through the batten to the board?

Hi @Jithesh 

Here is a side profile which would be mirrored either side, then a batten runs along the back wall.

Flat head screws through pre-drilled pilot holes through the steel tubing into the bench top. The front cover strip can be nailed, punched and filled into the edge of the benchtop and will secure the tube in place.

Battens to have pilot holes for long thick gauge wood screws into studs. You will pick studs up in the corners in on a slight angle. You may a need a wall fastener at the front end of the side battens unless you can bring them right to the front.

Hope that makes sense.

Thanks all.

I have got everything delivered from bunnings and will start on the project soon. Wish me luck!
