Plate LXII. Staircases with “Returned” Flights Planned within a Square

Plate LXII. — The diagrams on this Plate represent motives for square staircases with flights returned in each case. No. I shows the simplest type with short flights and quarter-space landings. No. II is larger in its dimensions, the flights being carried on walls and screened by columns which in turn support the covering over the well, in which a top-light is formed. In No. III the staircase is designed about an open well and is contained within a square, round which circulating corridors, screened by columns, complete the design. No. IV shows a staircase of three flights only, arranged about a central well, the fourth side of the square being taken up by the landing. No. V shows a staircase with returned flights arranged within an open square. The staircase shown in plan No. VI and perspective sketch No. VII consists of three flights placed against the sides of a square hall. It is partially screened by a colonnade upon which other columns are superimposed at the first floor level: this is an effective arrangement admitting of correct emphasis being given to the first floor approach.
