How to apply

Develop or utilize AI tools that can process floor plan data to generate predictive valuations and identify optimal spatial arrangements for new developments.

Project actions

01Consider using computational methods to analyze design elements.
02Focus on how relationships between components (not just individual components) can impact user perception or market value.

Method & Evidence

AimCan graph convolutional networks, trained on access graphs derived from floor plans, accurately estimate real estate rental values and identify key spatial features influencing these values?

MethodMachine Learning / Computational Modelling

ProcedureAccess graphs representing room adjacencies were automatically extracted from rental apartment floor plans. A graph convolutional network (GCN) was then defined and implemented to process these access graphs. This GCN model was used to estimate floor plan values, which were then integrated into a hedonic pricing model to estimate rents. The accuracy of this new model was compared against conventional models, and the learned GCN was analyzed to identify influential spatial features.

Strengths & Limitations

Strengths

+Novel application of GCNs to floor plan analysis for valuation.
+Demonstrated significant improvement in estimation accuracy.
+Provides interpretable insights into influential spatial features.

Limitations

The accuracy of the AI model depends heavily on the quality and quantity of the training data. It might not capture subjective aesthetic preferences or unique lifestyle needs.
