Abstract
Shop houses at Soi Phrayasri, Fueang Nakhon Road, Bangkok demonstrate blend of Thai and Western
architectures, which are under supervision of the Crown Property Bureau. The properties are rented by local
people for accommodation and commercial purposes, such as restaurants. According to a survey, there were
problems about area usages and damages of buildings, both exterior and interior spaces. Objectives of this
research were: 1) to study architectural characteristics, physical environments, and behaviors of restaurant
customers in areas of shop houses at Soi Phrayasri, 2) to study opinions of entrepreneurs and customer
satisfaction towards interior environments of restaurants in shop houses at Soi Phrayasri and 3) to study
renovation problems and improvement methods for shop houses at Soi Phrayasri which are conservation
buildings to fulfill requirements of restaurants in terms of materials, light, space allocation, furniture styles, and
modern technologies to be used in conservation buildings.
This research combined both qualitative and quantitative research, in which data were collected from
documents, surveys of physical environments, and behaviors of restaurant customers in the area. Respondents
of interviews included 4 restaurant entrepreneurs and 30 customers. Research tools included a physical
environment survey form, an interview form, and a questionnaire. Qualitative data were analyzed, summarized,
and prioritized. Quantitative data were analyzed by using frequencies, percentages, means, and standard
deviations to compare customer satisfaction towards restaurant space usages.
The findings showed that the shop houses at Soi Phrayasri illustrate Thai and Western architectural
characteristics in 2-storey format. The buildings are equipped with hip roof (Panya style) using kite-shaped tiles,
walls decorated with stucco, and doors and windows decorated with mullion. According to recent conditions,
buildings of restaurants in research area were run-down from wear and tear. Main problems were that most
restaurants set up cooking area in front of the building, service areas were beside footpath, and storage areas
for stuffs and ingredients were inside restaurants. Regarding renovation methods for conservation buildings to
suit requirements of restaurants in terms of materials and paint, more than half of customers perceived that
some parts of restaurants should be renovated as appropriate, such as walls, floors, and ceilings, by cleaning,
mending cracks, painting or coating cement surfaces. Regarding brightness, light is enough but shape of lamps
should be improved, cool white light should be used, and façades should coincide with buildings. Regarding
space allocation, cooking areas should be placed inside restaurant, in case that cooking areas were in front of
restaurant, partitions were required to separate cooking areas and outside areas. Service areas should be placed
inside restaurant and unnecessary things inside restaurant should be managed to ensure efficient space
utilization. Regarding furnitures, size should be standard that coincide with building and utilization. Regarding
modern technology, entrepreneurs showed no demand for air conditioning systems and Wi-Fi but needed TV
and fire protection systems.
