What is a kitchen extension?
A kitchen extension is a building project that increases the size of your existing kitchen by extending the footprint of your home, most commonly to the rear of the property, or into a side return where space allows. It is designed to improve how the kitchen works day to day by creating more usable floor area for cooking, dining, storage and circulation, and by allowing a more efficient layout than the original room often provides.
In many homes, especially terraced and semi detached properties, the existing kitchen can feel narrow, enclosed or disconnected from the garden. A well designed kitchen extension enables you to reconfigure the space to suit modern living, often creating a larger kitchen dining area with improved natural light and a stronger relationship to the rest of the ground floor. When planned properly, a kitchen extension can feel like a natural continuation of the home, balancing practicality, comfort and long term value.

Why Extend Your Kitchen?
A well designed kitchen extension can transform how your home looks and functions, while adding long term value. Key benefits include:
- More space for modern living
Create a larger kitchen, kitchen diner, or open plan layout with improved storage,
worktop space and everyday usability.
- Increased natural light
A kitchen extension can significantly brighten the space through larger glazing and
well positioned rooflights.
- Better flow and improved layout
Reconfigure the ground floor to enhance circulation and reduce cramped or underused
areas, especially in terraced and semi detached homes
- Stronger connection to the garden
Improve the relationship between indoor and outdoor space with wider openings and better access to the rear.
- Added property value and market appeal
A high quality kitchen extension is one of the most effective ways to enhance resale potential and overall buyer demand.
- Compliant, build ready design
Proper design development ensures your kitchen extension meets planning requirements where needed and is fully coordinated for construction
Our focus is always on delivering kitchen extension design that works beautifully in everyday life, not just on drawings.

Our Approach to Kitchen Extensions at Salstan Architecture
At Salstan Architecture, our approach to kitchen extensions is centred on creating a space that feels natural to your home, works effortlessly day to day, and is properly resolved for planning and construction. We start by understanding how you live now, what is not working in the existing kitchen, and what you want the extended space to achieve, whether that is an open plan kitchen diner, a better connection to the garden, more storage, or improved flowthrough the ground floor.
We then develop a design that balances practicality and aesthetics, with careful consideration of natural light, layout efficiency, proportions, and materials. For terraced and semi detached homes, we pay particular attention to side return opportunities, neighbour relationships, privacy, and how the extension sits within the character of the property. Every kitchen extension design is progressed with buildability in mind, including coordinated drawings and clear technical detailing, so the project can move smoothly from design to site.
Where required, we guide you through planning permission and approvals, and we keep the process straightforward, responsive, and well managed from the early concept stage through a build ready package. The result is a kitchen extension that is not only visually strong, but genuinely improves how your home feels and functions.
Our Process Explained in Six Easy Steps
Step 1 - Your 3D Site Survey
An appointed surveyor will come around for a full measured survey of your property. They will also note down all your desired requirements for your proposal.

Frequently Asked Questions
For a typical 30 m² kitchen extension, that usually means a total budget in the region of £50,000 to £95,000, depending on specification, structural complexity, and finishes. For larger or more complex kitchen extension projects, budgets can rise to £150,000 to £200,000+.
Not always. Some kitchen extensions can be built under Permitted Development if they stay within the relevant size, height and location limits, and the property has Permitted Development rights.
For a typical single storey kitchen extension, the construction phase is often in the region of 10 to 14 weeks, depending on complexity, access, specification, and how much internal reconfiguration is included. If you include design, approvals and prestart preparation, the overall timeline is usually longer.
Yes. We provide a complete design and build service delivered by our in house team, with civil engineering and project management integrated into the process. This creates a smoother route from concept and planning through to a build ready package and high quality on site delivery.
