Royal Oak is a £6.5m mixed-use development in London, transforming a Grade II listed pub into a high-performing asset through smart architecture and interior design. LP Arkinnovation delivered RIBA Stages 0–3, focusing on feasibility, planning strategy, and concept design to maximise return on investment. The project blends heritage conservation with a four-storey residential extension, unlocking value through adaptive reuse and efficient space planning. Designed for long-term performance, it balances character, compliance, and commercial viability, demonstrating how strategic architecture in London can enhance both lifestyle and asset value.
