MATERIALIZATION
…In order to understand architecture, it is important that we should keep
in mind the most subtle and powerful principle of all arts:
the agreement between material and form, made as intimate and thorough
as possible by the nature of things.
….The fusion of these two elements is the absolute aim of all great art….the simplest example is offered by poetry which cannot exist without the close
association or the magic symbiosis of sound and meaning…
Paul Valery

1. THE MATERIALS
Selection of materials should be done with a highdegree of coordination:
a) seeking material unity (large number of different materials tend to create a sense of disunity )
b) atmosphere or feeling (expression)
c) texture compatibility (association among materials)
d) surrounding buildings (uses and patterns)

2. THE ENCLOSURE
The materialization of the is the
creation of the physical shell around the building spaces.
This materialization is concerned with the relationships between:

2. THE ENCLOSURE
The enclosing planes of a building include its...
Roofs and Ceilings:- The roof plane and the ceiling plane may be the same (i.e. wood deck) or two different surfaces (dropped ceiling)- Avoid roof situations that trap water.- The protection of overhangs should be used only when needed.Floors:- In multi-story and basement conditions, the floor is similar to the roof framing.- Where land contours are pronounced, floor levels of spaces may impose upon or be in sympathy with the land.Walls:- Walls may be structural (bearing other loads) or non structural (only holding up their own weight)- Non-structural walls are used for barriers or filters between two conflicting or incompatible situations: walls may be temperature, acoustic or visual barriers.

2. THE ENCLOSURE
Openings in buildings may take several forms:
Openings should be woven into the entire building geometry as strongly as possible
Doors- Door placement should relate to the circulation system in the building and spaces. It determines the number of used areas formed in a space.- Doors should rest against a wall when open. This minimizes swing area needed and door interference with space activities.- Interior doors swing into its space while exterior doors swing out.Windows- The extent and placement of window openings should relate to space need for view, light or protection from outside forces.- Window sill height should relate to furniture height where furniture is against a wall at a window.
- Window placement must respond to view orientation of spaces.

3. The Structure
3.1. STRUCTURAL REQUIREMENTS
• DURABILITY The durability of the structure depends entirely in the physical/chemical conditions of the structural material, and our willingness to continue using the building ( at the end of the lifecycle of a building, it may be demolished)
• STABILITY AND EQUILLIBRIUM When the structure is stable and in equilibrium it resists any load without suffering a major change of shape or collapsing.
• STRENGTH AND RIGIDITY Strength and rigidity are reached by the adequate specification of geometry, size, and the material of the structural elements. In example, for resisting the same structural load, a steel structural element needs a smaller cross section than a reinforced concrete element, and this is due to the difference between the strength of the kind of materials.

3. The Structure3.2. Structure Types
3.2.1. POST AND BEAM STRUCTURES Most architectural structures are of the post-and-beam type.
Post and beam buildings carry the weight of their structural components (and the weight of objects and people in them) by bearing on one another.
The weight of the roof and beams is carried by the posts down to the foundation and then into the ground. Horizontal beams are subject to bending loads, therefore the structural materials should be able of resisting both tension and compression.
We can further subdivide the post and beam structures into:
