Is Samsung P920 suitable for Singapore condo door?

Samsung did a great marketing job in creating appeal for their flagship Push n Pull lock. We have to do something special at the Trilinq condominium to fit the lock in between the tight space between the door handle and vertical pull bar.

Is a double door handle (one from the door and one from the lock) a rational approach from an aesthetic and usage perspective? What do you think?

PS. Do you think this Gateman A20 approach is more practical on the aesthetics and on the budget?
