Customer Success Stories
Frequently asked questions (FAQs)
What's the difference between a single storey and double storey extension?
A **single storey extension** adds space on the ground floor, often for a kitchen-diner or living area. A **double storey extension** (or **two storey extension**) adds space on both the ground and first floors, ideal for expanding living areas downstairs and adding bedrooms/bathrooms upstairs. Both require careful planning and adherence to **Building Regulations**.
Do I always need planning permission for a house extension in the Northwest?
Not always. Many **single storey rear extensions** and some **double storey extensions** can fall under **Permitted Development rights**, depending on size, height, and proximity to boundaries. However, it’s crucial to confirm this with your local authority (e.g., **Manchester City Council**, **Cheshire East Planning**) and obtain a Lawful Development Certificate. We manage this process for you.
How much does a house extension typically cost in Greater Manchester or Cheshire?
Extension costs vary significantly based on size, complexity, materials, and ground conditions. For a **single storey extension**, expect roughly £40,000-£80,000. A **double storey extension** could range from £90,000-£140,000. These are estimates; we provide a transparent, no-obligation quote after assessing your specific project.
What's involved in Building Control approval for an extension?
**Building Control** ensures your **house extension** meets safety, structural, and energy efficiency standards. This involves submitting plans, inspections at various stages (foundations, damp proofing, drainage, structural elements, electrics, plumbing), and final sign-off. We handle all liaison with Building Control for your peace of mind.
Can you help with a kitchen extension or open-plan living conversion?
Absolutely. **Kitchen extensions** and creating **open-plan living** spaces are among our most popular projects. This often involves **wall removals** (including load-bearing walls requiring **RSJ installation**), new **plumbing** and **electrics** for kitchen islands, and seamless integration with dining or living areas. We manage the entire transformation.
What are the benefits of a garden room compared to a traditional extension?
A **garden room** offers a versatile, often quicker-to-build, and potentially more cost-effective way to add space, ideal for a home office, gym, or studio. Unlike a traditional **house extension**, they often fall under **Permitted Development**, simplifying the planning process. We build bespoke **garden rooms** tailored to your needs.
Do you manage the entire extension project, including all trades?
Yes, we pride ourselves on being your **full-service extension company**. Our team handles everything from initial design and **structural alterations** to **brickwork**, **roofing**, **electrical**, **plumbing**, **heating**, and final **finishes**. You’ll have one dedicated project manager, ensuring a cohesive and stress-free build.
How long does a typical house extension project take?
The **timeline for a house extension** varies significantly based on size and complexity. A **single storey extension** might take 8-12 weeks, while a **double storey extension** could be 16-24 weeks. We provide a clear project schedule upfront and work efficiently to minimise disruption to your home life.
What's the typical process for a Party Wall Agreement during an extension?
If your **house extension** involves building on or near a boundary with an adjoining property, a **Party Wall Agreement** may be required under the Party Wall Act 1996. This involves serving notice to your neighbours. We can advise you on whether this is necessary for your project and guide you through the process, helping to ensure smooth relations and legal compliance.
Can you help with extensions on uneven ground or properties with challenging access in the Northwest?
Absolutely. Our decades of experience across the Northwest mean we’re well-versed in handling diverse site conditions, including uneven ground, sloped sites, or properties with restricted access. We conduct thorough site assessments and work with structural engineers to design bespoke foundation solutions that ensure stability and safety, no matter the challenge.
How does an extension impact my home insurance and council tax?
Adding a **home extension** will likely impact both your home insurance and council tax. You must inform your home insurer of any significant structural changes to ensure your property remains adequately covered. Council tax bands are reassessed by the Valuation Office Agency (VOA) after an extension is completed, as the property’s value and size have increased. We advise clients to consider these implications during the planning stage.
