We prepare a comprehensive technical package including detailed drawings, FF&E schedules, joinery details, lighting layouts and specifications for construction.

Step 5:

Construction & Site Coordination

KTM Design works closely with contractors and project teams during the build phase, responding to site queries and ensuring the interior design is delivered accurately.

New Build Interior Design Ideas & Inspiration

Successful building construction interior design balances aesthetics with functionality and longevity. Below are some key considerations that help new construction projects stand out.

Integrated Interior and Architectural Design

When interiors are planned alongside architecture, the result is a more cohesive, efficient and visually striking building.

Durable, Future-Proof Materials

Selecting high-quality, hard-wearing materials during construction reduces maintenance costs and extends the lifespan of the interior.

Flexible Layouts

Designing adaptable spaces allows buildings to evolve with future use requirements, increasing long-term value.

Natural Light & Spatial Flow

Maximising natural light and creating intuitive circulation improves wellbeing, productivity and overall user experience.

Sustainability & Energy Efficiency

Thoughtful material selection and lighting design can significantly contribute to sustainability targets and operational efficiency.
