The bottom moves out on spiral screw. Balcony: A balustrade platform with access from an upper floor level. Baluster: One of the vertical pieces of a stair or porch railing. Balustrade: Railing fixed from stair treads, landing, balcony or bridge. Bargeboard: A wide timber piece or more recently metal piece at the end of the gable screen off ends of tiles, battens etc. Bay window: A projecting compartment that is glazed and has windows all around.

Bi-fold doors: A door consisting of a number of hinged leafs folding to one or both sides of a door opening. B.O.S.: (Building over sewer). Sometimes the location of the sewer pipes makes it necessary to build over them. In order to do that we need to estimate the additional cost and that requires that we have a Water Board inspector meet on site and tell us exactly how big the pipe is and how deep down it is. The pipe is then encased in concrete (See zone of influence). Bottom plate: Timber plate at the bottom of a wall frame. Box gutter: A roof guttering which is not on the exterior edge of the roof.
