Exterior sliding patio pocket doors

[lakelandfolk]

We intend having 2.5 m wide patio doors in the proposed extension to be built later this year, we don't want bi folds because of the broad sight line they have. We have looked at a few web sights and some offer a sliding patio door in a pocket system. That appeals as there will be a 3 m section of wall to one side of the door opening which could accommodate the pocket unit. It would also appear that a single door panel of 2.5 m would be possible, so a 2.5 m wide window with no sight lines which would open fully appears to tick all the boxes.

Has any one looked at this option?  Does it sound feasible?  Any suppliers to recommend?  We have not yet decide whether to build the extension in TF or masonry so going with an external pocket door could influence our decision.
