Descriptive models of housing spatial features based on Geographic Markup Language (GML) and its application are presented in this paper. The types and relationships between housing spatial features are firstly analyzed

and a new model for describing housing features is then proposed using the concept of standard cell from the point of reducing storage redundancies and improving query efficiency. Base on this

housing spatial features description and relationships between them based on GML are further put forward. These housing spatial feature models are defined as NatureStoreyModel

LogicalStoreyModel StandardCellModel

CellModel and LineModel

and the relationships are defined as natureStoreyMember

logicalStoreyMember

standardCellMember and lineMember. A schema defining the GML structure is given

incorporating both the geometry and attribute of housing features. And an application system used to manage housing information is developed based on Java

document object model (DOM) and simple application interface for XML (SAX). The implementation of the proposed models is tested through the system and the results approve the capability of the models.
