6.3 Method applied and classification system Having examined the effectiveness for the Bangkok situation of each previously employed method to estimate the number of houses, it was decided to adopt a housing unit count technique complemented for some areas with a land use method. The enlarged SFAP at the scale of 1:15,000 gave sufficient resolution for counting individual dwelling units in most areas; where counting proved difficult, spatial characteristics associated with each residential land use were applied. For multi-storey buildings, which the previous findings confirmed to generate great error (Watkin, 1984), other more reliable sources of information, such as questionnaires or fieldchecks, were needed. A set of residential classifications was developed so that housing unit count could be carried out systematically. The classes should be used to deter mine how the condition of housing stock has changed over the last decade. Three main classes, private, public and informal, were applied, and those classes were further sub-divided into 10 types of housing projects. Through interpretation, and delineation of air photographs, data regarding residential area devoted to each subclass, were obtained. One might argue that it is not possible to identify private or public sectors, as such is not identifiable on air photographs; to a certain extent, information from other sources, and local knowledge, were applied. The majority of housing type classifications were, however, seen on aerial photographs. These 10 classes were further sub-divided by building types for counting the number of houses in each residential area unit (polygon). A detailed description of the residential classification is given below. 6.4 Description of the classification 1 PRIVATE FORMAL 1.1 Shophouse project The floor plan of a shophouse is that of a rectangle. They occur in terraces of 8 to 20 units. The average unit size is 4 meters frontage by 12 meters in depth. Construction is normally multi storey, from 2 to 4 storeys. The ground floor is used for commerical purposes and the upper floors are residential, often occupied by a single family. Shophouses are usually found bordering main and secondary roads, and are often grouped to form small commercial residential areas. 1.2 Private housing projects (Developer build housing) These vary in form and type, consisting of detached dwellings, terraced houses or multi-storey apartments, and combinations of these types within the single development. Private housing projects are normally well-planned, and serviced by high standard access roads. House construction and design is normally uniform and of a high standard. 1.3 Land sub-division project These consist of large tracts of land which have been planned and sub-divided into individual build ing plots, either with or without the provision of infrastructural services. A regular street pattern is a readily recognizable feature. Generally, dwel lings are individually designed detached houses, and are well-planned, but lay-outs differ from one dwelling to another. Construction is on piece-meal basis so a number of vacant plots between each house is generally found. 1.4 Individual building These can comprise detached dwellings, small scale terrace developments, small scale shophouse developments; these are scattered throughout the city. 2 PUBLIC FORMAL Public Housing projects: Housing projects built by National Housing Authority (NHA) and other govern ment agencies (i.e. non NHA). 2.1 NHA project The NHA is responsible for constructing low income housing, which it does by building various forms of housing, including detached, semi-detached and terraced housing, four storey walk-up, and multi storey apartments including the provision of infrastructure. In addition to standard house building, the NHA also undertake sites & services housing schemes. 2.2 Non NHA project Other government agencies also provide housing for their employees, under social welfare programmes. Various types of housing, including detached houses, terraced houses, and apartment blocks. (Information on the public sector was taken from other sources) 3 INFORMAL SECTOR 3.1 Slums and Squatter type settlement Areas with dense, small, irregular, owner-built temporary and semi-permanent dwellings. Access and services are limited, and the quality of materials is often poor, resulting in poor living conditions. 3.2 Potential slums These areas demonstrate many of the same charac teristics as slums; however, their density is usually lower and dwelling sizes are larger; usually to be found on the fringe areas of the city. 3.3 Mini-slum These have the same characteristics as slums but each area so defined is limited to 30 dwellings. Such settlements are scattered throughout the city and occupy in-fill sites. 3.4 Klong Houses These are mainly traditional Thai-style houses situated on or near the banks of Klongs (Canals). They are characterized by having their principal access to the adjacent waterway and form ribbon developments to the waterway. In the inner city areas many such houses have degenerated into slums. 4 OTHERS These are housing units which cannot be classified under any of the above categories and consist of structures used living though not necessarily for residential purpose; for example, out-buildings, such as servant quarters garages, sheds and all makeshift structures built to house construction workers. Some temples, high-rise slums, industrial dormitories, and boat houses fall into this category. The classification is subdivided into building type as follows:
