SINGLE DWELLING - GENERAL
DESIGN REQUIREMENTS
Foreword
The TCVN 13967:2024 is developed by the Vietnam Institute of
Architecture (Ministry of Construction) under cooperation with Institute of
Building Science and Technology (Ministry of Construction), compiled by the
Vietnam Fire and Rescue Police Department (Ministry of Public Security),
proposed by the Ministry of Construction, appraised by the Commission for
Standards, Metrology, and Quality of Vietnam, and published by the Ministry of
Science and Technology.
Introduction
This document is developed on the basis of learning from
international experience and practical situations in Vietnam. Considering the
diversity of single dwelling models, especially existing single dwellings, this
document only prescribes general technical requirements for design. On the
basis of these requirements, relevant individuals and organizations may choose
different solutions (regarding appropriate materials and structures) for
designing single dwellings satisfactory to occupation demands on the basis of
ensuring load-bearing and use safety requirements, including fire safety
requirements, etc.
This document presents several solutions and illustrations
for specific cases in order to facilitate the application hereof.
