SASI Studio

SASI Home offers a highly personalised, design-led approach to high-end residential interior design and renovation in London. Combining interior design expertise with architectural thinking, we look beyond individual rooms to understand the property as a whole: its layout, proportions, natural light, circulation, storage, functionality and atmosphere. We work with private homeowners, families, professionals and international clients looking to transform apartments, houses and luxury residential properties. Our projects range from full home renovations and refurbishments to extensions, kitchen and bathroom design, space planning, bespoke joinery, integrated storage, furniture and lighting selection, material specification and final styling. Our work is contemporary, refined and timeless, with a focus on natural materials, elegant proportions, thoughtful colour palettes and bespoke details. Rather than applying a fixed aesthetic, every interior is shaped around the architecture of the property and the client's lifestyle, personality and requirements. A key part of our approach is combining architectural thinking with interior design. We consider how a home functions and how spaces connect before developing its visual identity. This allows us to create interiors that are not only beautiful, but also practical, comfortable and tailored to everyday life. We support clients throughout the design journey, from the initial brief and space planning through to concept development, material and furniture selection, bespoke joinery, procurement and implementation. Where required, we work alongside architects, contractors, consultants and suppliers to ensure the design vision is maintained throughout the project. Based in London, we have a particular focus on Central and Prime Central London, including Chelsea, Kensington, South Kensington, Knightsbridge, Belgravia, Mayfair, Marylebone and Notting Hill, while also considering selected projects across Greater London. Our clients value our ability to listen carefully, provide clear creative direction and manage the many decisions involved in a residential project. With a strong attention to detail and a calm, organised approach, we aim to create homes that are sophisticated, functional and genuinely personal.
