Common Types of House Extensions We Build
We design and build a wide range of house extensions to suit different
property types, layouts and budgets. Below are the most common extension types we deliver.
* All prices are indicative and subject to a detailed site survey and final specification.
Rear House Extensions
A rear extension extends the back of your property into the garden, creating additional living space such as a kitchen-diner or open-plan living area. This is one of the most popular and cost-effective home extension options.
Ideal for:
- Kitchen extensions
- Open-plan living and dining areas
- Family and entertainment spaces
Typical cost range in Croydon / South London:
Most rear extensions typically cost between
£1,900 and £2,400+ per m², depending on design complexity,
structural requirements and finish level.
Side Return Extensions
A side return extension utilises the narrow strip of unused land alongside a property, commonly found in Victorian and terraced houses. It is an excellent way to widen existing rooms without extending too far into the garden.
Ideal for:
- Widening kitchens and dining areas
- Improving natural light
- Victorian and terraced properties
Typical cost range in Croydon / South London:
Side return extensions typically cost between
£2,100 and £2,700+ per m², depending on access constraints,
structural alterations and glazing specifications.
Wraparound Extensions (Side & Rear)
A wraparound extension combines a side return and rear extension, creating a large, flexible ground-floor living space. This option offers the greatest design freedom and dramatic transformation.
Ideal for:
- Large open-plan kitchen-living spaces
- Modern family homes
- Maximising ground-floor footprint
Typical cost range in Croydon / South London:
Wraparound extensions usually cost between
£2,300 and £2,900+ per m², depending on the scale of the build,
foundation works and architectural detailing.
Double Storey Extensions
A double storey extension adds space across two levels, providing additional rooms both upstairs and downstairs. It is an excellent long-term investment for growing families.
Ideal for:
- Additional bedrooms and bathrooms
- Long-term family living
- Increasing overall property value
Typical cost range in Croydon / South London:
Double storey extensions typically range from
£2,100 to £2,600+ per m², influenced by structural engineering,
internal layouts and overall build specification.
Orangery Extensions
An orangery extension is a stylish way to add light-filled living space that blends the solid structure of a traditional extension with the openness of glazed designs. Orangeries create a seamless connection between your home and garden, while offering year-round comfort.
Ideal for:
- Elegant kitchen-diners and family rooms
- Bright living spaces with garden views
- Homes seeking a premium architectural finish
Typical cost range in Croydon / South London:
Orangery extensions typically cost between £2,500 and £3,800+ per m², depending on glazing quality, roof lantern design, thermal performance and structural detailing.
(Depending on glazing specification, roofing design and structural detailing)
Single Storey & Ground Floor Extensions
A single storey extension is a practical way to increase ground-floor living space without altering the overall structure of your home. These extensions are commonly used to create open-plan kitchens, dining areas or larger living rooms.
Ideal for:
- Open-plan kitchen and dining spaces
- Family living areas
- Ground-floor layout improvements
Typical cost range in Croydon / South London:
Single storey extensions typically range from
£1,900 – £2,400+ per m², influenced by structural engineering, internal layouts and overall build specification.
(Turnkey build, excluding kitchen units and specialist finishes)
Kitchen Extensions
A kitchen extension is one of the most popular and practical types of house extensions, particularly for homes in Croydon. Most commonly built as a rear or side return extension, it is often delivered as part of a wider home extension project to create a spacious, modern kitchen-diner that naturally becomes the heart of the home.
As experienced builders, Art & Build Ltd deliver kitchen extensions as part of larger extension projects, ensuring the new space works seamlessly with the existing structure and complements the character of the home.
Ideal for:
- Kitchen-diners and open-plan layouts
- Family-focused living spaces
- Entertaining and social areas
If your project includes a full kitchen fit-out, see our kitchen installation service.
Typical cost range in Croydon / South London:
Kitchen extensions generally cost between £2,000 and £2,600+ per m², depending on structural openings, glazing systems and integration with existing living spaces.
(Excludes kitchen units and appliances.)

Step 2. Design & Planning Support
Where required, we provide full design and planning support, including concept layouts, coordination with architects and engineers, planning applications and structural calculations. This ensures your house extension is fully compliant and well prepared before construction begins.

House Extension – Frequently Asked Questions
Do I need planning permission for a house extension?
Planning permission depends on the size, design and location of your extension. Some projects fall under permitted development, while others require full approval. We can assess your plans and provide guidance on planning requirements and applications.
Do you offer both design and construction services?
Yes. We provide a complete house extension service, covering design coordination, planning support and full construction. We can also build from existing, approved plans if you already have an architect or designer.
How long does a typical house extension take?
Most house extension projects take between 12 weeks and 6 months, depending on size and complexity. A clear programme is agreed in advance, with regular updates throughout the build.
Can I stay in my home during the extension works?
In many cases, yes — particularly for rear or single-storey extensions. For larger or more complex projects, temporary relocation may be recommended. We will always discuss this with you in advance and help plan accordingly.
Will I receive a clear quote before work begins?
Yes. Following an initial consultation and site visit, we provide a detailed quote outlining the scope of works and expected costs. Any changes are discussed and agreed before proceeding.
Are there any hidden costs?
No. We believe in transparent pricing. All known costs are outlined upfront, and any variations or additional works are clearly communicated and approved before they are carried out.
What guarantees do you provide?
All house extension projects are completed to current building standards and covered by workmanship guarantees. Specific warranty details are discussed during the consultation.
