Hi,
This is my living room wall where I am going to place my tv (duh), cabinet and shoe cabinet.

Initially wanted to do a normal tv wall with acrylic, glass or melamine or laminate.
Then decided on a design to use porcelain slab for tv wall and the rest laminate .

But the socket placement proved to be a challenge as it is starting from 2700mm and ends at 3500mm.
Laminate/porcelain slab is 2400mm. From there I will have balance of 180mm for a floating cabinet 530mm off the ground.
Tv is 680-710mm off the ground. Meaning there is only a balance of 180mm between the edge of the tv and edge of the laminate.
Another problem would be that the console cabinet would either be going over the socket or be on top of the socket which would be too high.
Spent weeks/months looking for a suitable design to get around this.
Another problem I have with this is that the tv wall will be bigger than the seating area meaning the tv will be off center (to the left) and that means that the sofa will have to be a bit to the left in order for it to be center with the tv.
After searching high and low online for inspiration I found this design that I love very much.

It is flushed. Everything is neat and tidy and tucked away. Everything is floating.
Plus there is space below the tv to tuck away extra chairs as my sofa is just a 2 seater.
My living room is quite small so it would be nice to have extra chairs available that can be tucked neatly nearby.
I thought I could follow the design above and put my decoder in the mirror cabinet.
I thought the issue would be opening a socket for the console.
Only later on I realized that I wouldn't be able to get signal from the remote to the decoder.
So back to having a decoder console hanging under the tv.
However like many designs that I see online, they are not practical (in our country) as we have astro decoder, tv box, etc.
They don't leave a space for decoders. I am guessing they leave it on top of the cabinet (floating or on the floor).
The other issue is that the prices for laminate wall is pretty expensive. Prices quoted ranges from RM7000-11000 for this job.
So I thought I could follow another of my favorite floating design that uses drywall I think.

Advantage of this design is that it should be much cheaper than laminate and also I am not limited by the size of the laminate which 2400mm.
With drywall I could have the hanging wall much longer and closer to the ground to perhaps 350-450mm.
Enough space for tv console compartment under the tv in 1 floating design.
However after 1 day I decided against it as I have a baby.
Drywall is very weak. If my baby decides to throw something against it or touch it, I will need to fix it and then repaint.
It will have some spots unless I paint the whole wall.
Too much work. Too much risk. So I decided against it.
So back to the drawing board with laminate.
One guy told me that he has a longer laminate of 3000mm which would be perfect as I can have it at my desired length anywhere between 2500-2600mm.
After meeting him, he said better to squeeze in the tv console/decoder in between the tv and end of the laminate. He said 150mm for decoder.
So it will look like this

Is the design good?
Price quoted is RM7000.
Is it reasonable?
The design looks ok, maybe you can adding a horizontal feature colour panel as indicated below to make the opening for decoder blend into the whole tv cabine design.
Don't forget to have concealed LED light strips under the TV wall panels, this way will look even better!!
