village with all the social, material, organizational spiritual and cultural element that sustain it.
5. Urban fabric The physical aspect of urbanism, emphasizing building types, thoroughfares, open space, frontages, and streetscapes but excluding environmental, functional, economic and sociocultural aspects
6. Urban structure... its the physical complexity of various scale, from individual building, plots, street-blocks, and the street pattern.
7. urban texture the geometrical structure formed by the spatial distribution of urban elements expressed as coarse or fine.

2. FORM2. FORM• Refers to the shape and arrangement of human settlement
while structure is the way they are organized. Form may be of:
• DESCRIPTIVE ASPECTS OF FORM
• Size, Density, Grain(coarse or fine), shape, pattern and focal organization.
• SETTLEMENT PATTERNS1. Dispersed2. Linear3. Nucleated4. planned
AS A PRODUCT (state of being) AS A PROCESS(state of becoming)1. The shape and structure2. Mode of existence3. Design of the human settlement4. Basic nature
1. Shaping of the human settlement.2. Ordering(hierarchy)3. Arrangement 4. The conception-abstract idea/mental symbol.

Hamlet Very small
Post office or perhaps none
Village Small Church, post office, school, small shops
Town Quite large
Several shops and churches, doctors/ dentist, bank, high school, supermarket
City Very large
Large railway station, shopping centre, cathedral, large hospital, museum, etc

•cultural production and from of the city,
• political control and town form.
• incremental nature of urban morphology and regional change.
• cultural context and orientation of contemporary urban planning..Usually these are within the town/city scale
Covers plot, block, urban form, Central Business District, lot, neighborhood form and typo morphology.
Generally these concepts are a transition between macro and micro scales. They focused on the district/ neighbourhoods level of the urban form.
Related to function, form, urban elements, urban solid and void, aesthetic, pattern, street, square, open land, urban structure and volume.
This kind of concepts more related to street, square and open spaces.
