That is a 48" built in. Looks like it is a GE Monogram however the interesting part is it looks like the wood panels have been stuck to the original stainless doors. Clever if that is the case. The panels for these are usually help on with a different looking trim than this.

With any of the built-in series refrigerators, you can purchase a trim kit and install custom wood panels to match your cabinetry.

Correct, 48" built in. The appliance selections for this project were odd & I can't remember the brand at the moment, but I believe Jerry may be correct w/ GE Monogram. The panels are NOT applied on top of SS doors, Wes is correct about the trim kit. I am personally not a fan of how GE refrigerators look w/ panels. I prefer Sub-Zero or the fully integrated options from Miele, Thermador, Bosch, & Gaggenau.
