Nowadays, due to rapid development and large populations especially in urban areas has caused indoor spaces of buildings becomes bigger and more complex. In most developing countries, the needs of advance cadastre systems and land administration are vital due to rapid development and large population area especially in the city centre such as Kuala Lumpur. More populations have caused more limited space, which explains the need to build a more vertical building. Due to this, an efficient strata management are required for managing the strata title. A study of country-based profile on cadastre domain standard has been conceptualized for land administration in Malaysia that allows integration of 2D and 3D representation of spatial units with supports of both formal and informal Rights, Restrictions and Responsibilities (RRR). Since this research used Malaysia cadastre management as a case study, the proposed model for the Malaysian land administration country profile was embedded in the integration model. Meanwhile, a new working item proposal for LADM Edition II has been introduced on the idea of encoding further integration of land administration with an existing standard such as IndoorGML. Hence, this paper proposes a conceptual model on the integration between both legal space (indoor) and legal object using LADM Edition II and IndoorGML standards for strata purposes. Three objectives had been recognized to achieve the aim of the study. Firstly, to identify the integration of spatial components and non-spatial components for strata management. The second is to develop a conceptual data model for strata with the integration of LADM Edition II and IndoorGML and lastly, is to develop a prototype to validate the proposed conceptual data model. Thus, the development of the conceptual model may provide insights or ideas for future work and land administration on strata purposes.
