Bespoke Interiors with Purpose

At Planning By Design, we create considered interior spaces that reflect your personality while making everyday life easier. We work with homeowners, businesses and developers on projects ranging from individual rooms to complete residential and commercial properties in London, across the UK and internationally.

Our collaborative approach combines space planning, furniture, finishes, lighting, colour and practical detailing into one cohesive design. Whether you already have a strong vision or need help discovering the right direction, our team will guide you from the first ideas through to a clear design package ready for implementation.

A collaborative approach

Beautiful Spaces, Thoughtfully Planned

The best interiors begin with understanding how you want the space to feel and function.

We take time to understand your requirements, personal style, practical needs and budget. Every recommendation is made with the complete space in mind, creating an interior that looks cohesive, feels personal and works for the people using it.

Where architectural or planning support is also required, our interior designers can collaborate with our chartered architects and town planners, keeping the wider project coordinated under one experienced team.

Our services

Complete Interior Design Support

Choose the level of support that suits your project. We can help with a focused room design or develop a coordinated scheme for an entire property.

Space Planning & Layout Design

We optimise room layouts, circulation and furniture placement to make the best use of the available space while improving comfort, usability and visual balance.

Furniture, Fixtures & Finishes

We select furniture, sanitaryware, finishes and materials to create a consistent design, with practical recommendations suited to your style and budget.

Lighting Design

We develop considered lighting proposals that combine natural, ambient, task and feature lighting to support both the atmosphere and function of each room.

Colour Consultation & Styling

From calm neutral palettes to stronger statements, we coordinate colours, textures and decorative elements so every part of the interior feels connected.

2D Drawings & Room Elevations

Detailed plans and elevations communicate the proposed layouts, dimensions, joinery and key design decisions clearly for review and implementation.

3D Visualisations

Where required, realistic 3D visualisations help you understand the completed space, compare options and approve the design with confidence before work begins.

Interior Design Frequently Asked Questions

What is the difference between interior design and architectural design?
Architectural design focuses on the building’s structure, form and overall layout. Interior design develops the experience within those spaces through layouts, furniture, lighting, finishes, colour, storage and styling. Our teams can work together where a project requires both services.
The cost depends on the number of rooms, project complexity and level of detail required. We agree the scope and price before work begins. You can request a detailed quotation or use our Free Online Cost Calculator for an initial estimate.
Depending on your brief, the package may include floor plans, furniture layouts, room elevations, moodboards, colour and material palettes, lighting proposals, 3D visualisations and a detailed furniture, fixture and sanitaryware specification with quantities, suppliers and estimated costs.
Yes. Where required, we can create detailed 3D visualisations to help you understand the proposed space and approve important design decisions before implementation.
Yes. We work on projects of different sizes, from individual rooms and focused consultations to complete residential and commercial properties.
Timescales depend on the size, complexity and level of detail required. We will explain the expected programme when confirming the scope. Allowing enough time for feedback and revisions helps avoid unnecessary pressure and supports a better final result.
A site visit can be arranged where required. However, many projects can be completed through our digital process using accurate measurements, photographs, videos and online consultations, allowing us to assist clients throughout the UK and internationally.
