The Petts Wood project highlights a classic value-add strategy through refurbishment and extension. The BALMA Group undertook a full renovation, including a rear extension and loft conversion, significantly increasing both usable space and market value. 

From a development perspective, this project demonstrates how structural enhancements can outperform new builds in certain markets. By retaining the core structure while expanding its footprint, the team optimised planning permissions and reduced overall development risk.

The technical execution required precise structural engineering—particularly in integrating the loft conversion and rear extension seamlessly with the existing building. This approach not only improved functionality but also modernised the property to meet current buyer expectations, proving that strategic refurbishment can deliver strong ROI with controlled capital expenditure.
