Architecture is besides its well known functions about designing spaces with appropriate characters. Spaces may have different characters like dominating spaces, pleasant spaces, depressing spaces and so on. Only in past century it was realised that space is supreme in architecture. Proportion, scale, ornamentation are some of the factors which render character to space. Let us examine them in more details.
Space is bounded, captured, enclosed and moulded by the form of building.
Form is made with elements like walls, columns, roofs among others. Variations in size, shape and proportion of these elements create different kinds of forms for e.g. Roofs can be flat, pitched or with dome to create different forms. But with R.C.C. practically any form can be built and the R.C.C. frame of beams, columns and slabs is enough for structural stability. Walls are made only for privacy. Therefore openings can be as large as is required for design.
