Interior Architecture & Space Planning in London

GI Design develops considered interior architecture and space planning solutions that improve how residential spaces function, connect and respond to the way they are lived in. From rethinking existing layouts to developing detailed plans for kitchens, bathrooms and bespoke joinery, we create a strong spatial foundation for the wider interior design.

Creating a Stronger Foundation for the Interior

Good interior design begins with understanding how a property should work. We look at the existing layout, circulation, room relationships, natural light, views and the practical needs of the people who live within the space before developing a clear spatial direction.

Our interior architecture and space planning service can include analysis of the existing layout, alternative layout options, furniture plans, scaled floor plans, kitchen and bathroom layouts, bespoke joinery layouts and other technical drawings required to develop the design.

Where appropriate, GI Design can recommend and design changes to the existing arrangement of a property, including alterations involving internal walls and the relationship between rooms. These decisions are developed around functionality, proportion, movement and the wider character of the home rather than simply increasing or reducing the size of individual spaces.

We also consider how spatial decisions affect the wider interior experience — from the way natural light travels through the home to sightlines, furniture placement, storage and the relationship between internal spaces and gardens or outdoor areas.

Where architectural or structural expertise is required, GI Design works directly with architects and structural engineers to help coordinate the intended design and carry the agreed spatial solution forward appropriately.

Interior Architectural Detail

Our work can include scaled floor plans, technical drawings, kitchen and bathroom layouts and bespoke joinery planning, providing the detail required to develop the wider interior design.

Layout Development

Alternative layouts, furniture plans and spatial arrangements are developed around the client’s lifestyle, priorities and the architectural character of the property.

Existing Layout & Spatial Analysis

We assess how the existing property functions, identifying constraints and opportunities to improve circulation, room relationships and the overall use of available space.

How we work

We begin by understanding the existing property, how the spaces are currently used and what you would like to change. From there, we analyse the layout and develop alternative spatial solutions before refining the preferred direction through furniture plans, kitchens, bathrooms, bespoke joinery and detailed drawings.

Where architectural or structural input is required, GI Design coordinates directly with the relevant professionals, allowing the agreed spatial framework to move naturally into the wider interior design and refurbishment stages.

Frequently Asked Questions

How does space planning relate to the Interior Design service?

Space planning establishes how the property should function and how its spaces relate to one another. The Interior Design service then develops the wider aesthetic and functional scheme through materials, colour, lighting, furniture, bespoke elements and styling.

What happens if structural work or specialist approval is required?

GI Design develops the spatial and interior design intent and collaborates with the appropriate architects, structural engineers or other specialists where their technical input or approval is required.


Does GI Design work with architects and structural engineers?

Yes. Where architectural or structural expertise is required, GI Design works directly with architects and structural engineers to help coordinate the intended design.

Can GI Design plan kitchens, bathrooms and bespoke joinery?

Yes. Kitchen layouts, bathroom layouts and bespoke joinery can all form part of the interior architecture and space planning service where relevant to the wider project.

Does GI Design provide floor plans and technical drawings?

Yes. Depending on the project, the service can include scaled floor plans, furniture layouts, technical drawings, kitchen and bathroom layouts and bespoke joinery plans.

Can GI Design recommend moving internal walls?

Yes. Where a better spatial solution involves altering internal walls or changing the existing arrangement of the property, GI Design can develop the intended design and work with the relevant architects and structural engineers where specialist input is required.

Can GI Design redesign the existing layout of my home?

Yes. GI Design can analyse the current layout and develop alternative arrangements to improve how the property functions, including the relationship between rooms, circulation and the use of available space.

What is interior architecture and space planning?

Interior architecture and space planning focus on how the internal spaces of a property are organised, connected and used.
