Technical Interior Design Drawings in London
Develop Your Approved Interior Design in Greater Detail. Once an interior design has been approved, the next question is often: how do we communicate the design clearly to the people involved in delivering it?
Oraanj produces technical interior design drawings for residential and commercial projects, developing approved concepts into detailed plans, elevations, lighting and electrical position coordination, bespoke joinery drawings, and selected material information.
Technical drawings can form part of a wider Oraanj interior design project or, where appropriate, be discussed as a separate service when sufficiently developed design information already exists.
What Are Technical Interior Design Drawings?
Moving From the Approved Design Into Measured 2D Detail
A 3D visual helps you understand what an interior could look like. A technical interior drawing communicates specific information about the design in a measured two-dimensional format.
Arrangements
Furniture & Wall Arrangements
Communicating where furniture is positioned, how interior walls are arranged, and key room dimensions.
Elevations
Wall Elevations & Joinery
Showing how wall elevations are composed and how fitted joinery relates to the surrounding room.
Coordination
Lighting & Electrical Intent
Showing where proposed lighting is positioned and how sockets and switches relate to furniture and joinery.
Materials
Selected Finish Information
Identifying selected floor finishes, wall finishes, paint colours, joinery finishes, and decorative materials.
When Do You Need Technical Drawings?
Connecting Approved Visual Concepts With On-Site Implementation
Once the visual direction has been agreed, a 3D image or mood board alone may not provide enough information to understand dimensions, positions, and relationships between elements.
1. Your Contractor Needs More Detailed Information
When renovating one or several rooms, detailed drawings help communicate the relationship between different parts of the approved interior to your builder.
2. You’re Planning Bespoke Joinery
Wardrobes, media walls, shelving, cabinetry, and other fitted elements need to be developed in relation to the surrounding room proportions.
3. You’re Planning Lighting & Electrical Positions
Sockets, switches, and lighting positions need to relate directly to furniture, kitchens, joinery, and the way the room will be used.

Residential & Commercial Technical Drawings
Detailed Interior Information for London Homes & Workplaces
Whether coordinating a principal bedroom suite, an open-plan kitchen-diner, or a commercial interior, drawing requirements are established around the individual space.

Supporting living rooms, bedrooms, kitchens, dining areas, dressing rooms, home offices, bathrooms, hallways, open-plan interiors, and whole-home renovations.
2. Commercial Interiors & Hospitality
Developing technical interior drawings for offices, restaurants, cafés, bars, retail spaces, and other commercial premises according to agreed scope.
3. From 3D Design to Measured Documentation
Together, 3D visuals, floor plans, wall elevations, lighting layouts, electrical layouts, and joinery drawings provide a complete understanding of the approved interior.
What Technical Interior Drawings Do Not Replace
Clear Distinction Between Interior Design Intent & Specialist Engineering
Oraanj’s technical interior drawings communicate the interior design intent within the agreed scope. Different professionals remain responsible for specialist engineering and fabrication.
1. Structural, M&E & Building Regulations
Separate specialist input is required for structural engineering, mechanical & electrical (M&E) engineering, HVAC, fire strategy, drainage, and statutory Building Regulations approvals.
2. Specialist Joinery & Kitchen Shop Drawings
Appointed joiners, kitchen suppliers, and specialist fabricators remain responsible for verifying site dimensions and producing manufacturing/shop drawings before production.
3. Electrical Installation, Testing & Certification
Qualified electrical professionals remain responsible for circuit design, electrical loads, cable sizing, distribution boards, safety testing, certification, and final installation.

Frequently Asked Questions
A floor plan looks down on the room from above and shows the arrangement of the space. An elevation looks directly at a selected wall and can show elements such as joinery, furniture, lighting and finishes.
Potentially. If your design is already sufficiently developed and reliable dimensions and information are available, we can review whether a standalone technical drawing service is appropriate.
DWG files can be provided where included within the agreed service.
Potentially, depending on the quality and accuracy of the information available. We need to review the existing file before confirming what can be produced from it.
Yes. Interior lighting layouts can be developed, and Oraanj can coordinate proposed interior positions for sockets, switches, lighting controls and selected electrical points. These drawings communicate interior design intent and do not replace specialist electrical engineering, installation design, testing or certification.
Yes. Interior joinery drawings can communicate the intended appearance, arrangement and relationship with the surrounding interior. Specialist fabricators remain responsible for verifying dimensions and producing any manufacturing information required for fabrication.
They are technical interior design drawings developed according to the agreed scope. They should not automatically be interpreted as complete construction, structural, M&E, statutory or specialist fabrication documentation.
The programme depends on the number and complexity of drawings and the quality of the information available. Timing is confirmed once the drawing scope has been established.
