Home Extensions
Design-led residential extensions tailored to your home, lifestyle and future needs
A well-designed home extension can transform the way you live, creating more space, improving natural light, and unlocking the full potential of your property. At Artist of Architecture, we design bespoke residential extensions that are carefully considered around your existing home, planning requirements, and the way you want to use your space.
From contemporary kitchen extensions and open-plan living spaces to sensitive extensions for period properties, our approach combines architectural creativity with practical technical knowledge to create homes that feel natural, functional and timeless.
We guide clients through every stage of the extension process, from initial ideas and feasibility through planning, technical design and construction support.
Why to build a Home Extension?
A home extension allows you to improve the way your property works without leaving the home and location you already enjoy. A carefully designed extension can create additional space, improve natural light, enhance the connection between rooms, and adapt your home to changing lifestyle needs.
Whether you need a larger kitchen, a family space, a home office, utility and storage space or improved circulation throughout your property, a well-designed extension provides a tailored solution rather than the compromises and expenses often involved in moving.
At Artist of Architecture, every extension is approached as an integrated part of the existing home. Through careful consideration of proportions, materials, natural light and how spaces are used, we create extensions that feel natural, practical and architecturally considered.
Types of Home Extensions We Design
Every property has different opportunities and constraints, which is why we design extensions that respond to the existing building, its surroundings and the way you want to use your home.
Our residential extension projects include:
Rear extensions are one of the most effective ways to create additional space, often improving connections between kitchens, dining areas and gardens while introducing more natural light.
Side extensions can unlock underused areas of a property and provide additional accommodation while maintaining a balanced relationship with the existing home.
Side return extensions are particularly effective for terraced and period properties where narrow side passages can be transformed into valuable internal space. They can help create larger kitchens, improved circulation and brighter open-plan areas while respecting the original character of the home.
Combining rear and side extensions, wrap around designs provide greater flexibility where larger improvements to space, circulation and layout are required.
Single storey extensions can transform ground-floor by creating larger kitchens, family spaces, home offices or improved connections with outdoor areas.
Double storey extensions provide an opportunity to increase space across multiple floors, adding bedrooms, bathrooms or additional habitable areas while maximising the potential of the property.
Kitchen extensions focus on creating functional, light-filled spaces designed around modern family lifestyle, entertaining and everyday use.
Properties located within conservation areas or areas with heritage considerations require a more sensitive design approach. Conservation extensions balance contemporary lifestyle requirements with respect for the existing character, materials and architectural context of the property.
Our Design Approach to Home Extensions
A successful home extension should feel like a natural evolution of the existing property rather than an addition that appears disconnected. Our approach begins with understanding the character of the home, the surrounding context and how each space is used by the occupants.
We carefully consider proportion, natural light, materials, views, circulation and the relationship between existing and new spaces to create extensions that are both practical and architecturally considered.
Whether designing a contemporary rear extension, a sensitive conservation extension or a complete transformation of an existing home, we aim to create spaces that can improve everyday life while respecting the identity of the original property.
Every project is developed around the individual requirements of the homeowner, resulting in a bespoke design solution that balances creativity, functionality and long-term value.

We provide a structured approach from concept through completion.
1. Initial Consultation
We begin by understanding:
Your goals and priorities
How you currently use your home
Your budget expectations
Planning considerations
Opportunities and constraints of the property
This allows us to identify the best design direction.
2. Measured Survey and Site Assessment
We analyse the existing property through detailed surveys and site observations.
This helps us understand:
Existing layouts
Structural considerations
Natural light opportunities
Relationship with neighbouring properties
Potential planning constraints
3. Concept Design
We develop design ideas that explore:
Layout improvements
Spatial relationships
Materials
Architectural character
Connection between existing and new spaces
The aim is to create a design that feels like a natural evolution of your home.
4. Planning Permission
Where required, we prepare planning drawings and supporting information.
We consider:
Local planning policies
Conservation area requirements
Neighbouring impact
Heritage considerations
Permitted development opportunities
5. Technical Design
Once the design is approved, we develop detailed information required for construction.
This may include:
Detailed drawings
Building regulation information
Technical specifications
Coordination with consultants
6. Construction Support
We can provide ongoing support during construction to help ensure the design intent is maintained.
Planning Permission for Home Extensions
Planning requirements depend on several factors, including:
Extension size
Property type
Location
Previous alterations
Conservation area status
Listed building restrictions
Some smaller extensions may fall under permitted development rights, but restrictions apply.
Properties in areas such as conservation areas or with heritage significance may require additional planning considerations.
Our approach is to assess the opportunities and constraints early, helping you make informed decisions before investing in detailed design work.
Designing Extensions for Homes
Properties often present unique architectural opportunities and challenges.
We regularly consider: Victorian and Edwardian terraces, Period properties, Conservation areas, Compact urban plots, Neighbouring relationships, Maximising natural light, Improving existing layouts.
A successful extension is not simply about adding square metres; it is about creating better spaces within the limitations and character of the property.
