Value-Add Duplex Apartment Case Study 📈
This case study demonstrates how adding an additional floor and reconfiguring layout can significantly enhance both rental income and capital value. By converting a one-bedroom apartment into a three-bedroom, two-bathroom duplex, the property was repositioned as a high-performing residential asset.
Design-led upgrades including matt black finishes, concrete-effect tiling, rustic oak flooring, and smoked grey blinds elevated the apartment’s appeal. The inclusion of a dedicated utility room further increased tenant demand and long-term usability.
Rental Growth & Capital Appreciation 🏠
The duplex conversion delivered a substantial uplift in monthly rent alongside a strong increase in valuation, reinforcing the commercial value of vertical extensions and intelligent space planning.
