Interior Architecture Services in London & Nationwide
Transformative Interiors Through Structural Design & Spatial Intelligence
At Oraanj Interior Design, our Interior Architecture service is where design meets structure. We specialize in redefining spaces with thoughtfully integrated layouts, architectural detailing, and materials that merge form with function.
Our clients—whether homeowners, property developers, or renovation specialists—choose interior architecture when a project requires more than decoration. We deliver intelligent, buildable spaces through structural planning, material detailing, lighting considerations, and architectural cohesion.

What Is Interior Architecture — and Why You Might Need It
Interior architecture goes beyond surface design and décor. It involves a deep understanding of how space works structurally and functionally. It can address:
- Spatial reconfiguration (e.g. removing partitions, creating flexible zones)
- Functional design that enhances daylight, movement, and layout
- Structural coordination with M&E (mechanical & electrical systems)
- Integration of architectural features like alcoves, built-in joinery, and material walls
- Compliance with building regulations and long-term usability
If your project involves improving flow, enhancing layout functionality, or adding architectural detail, Interior Architecture is the service you need to start with.

What the Service Includes
Our Interior Architecture service provides a comprehensive approach to structural design, including:
- Spatial and structural assessment based on survey or architectural plan
- Technical floor plans and layout proposals in CAD format
- Interior elevations and joinery drawings as required
- Material and finish selections coordinated with your designers
- Seamless integration of lighting, plumbing, and cabinetry plans
- Design documentation suitable for contractors and builders
This service can be used as a standalone architectural solution or integrated with our Full-Service Interior Design package for a complete, turnkey experience.
