An increasing number of homeowners in Lancashire and Cheshire are choosing to add double-storey extensions to their existing properties instead of relocating, as it involves less upheaval and expense. Integrating a quality extension into your home can elevate your living experience, and you need a company with the expertise to manage and construct it. That’s where Clearview comes in.
We have expertly managed numerous home extension projects and earned many referrals from satisfied customers. Additionally, we hold all the necessary accreditations


Estimating the cost of a double-storey extension is challenging without knowing details about your home, its location, and the specific functional requirements of the structure. The intended use of the extension can significantly impact the overall cost, so please provide us with as much information as possible.
Additional factors that could affect the final price include the potential need to extend your heating system and upgrade existing electrical systems. Clearview will assess your situation and has expert teams to handle these tasks.
Yes, double storey extensions do not meet the criteria set for permitted development and therefore full planning permission is required. The Clearview team will manage the application process on your behalf, relieving concerns you may have.

Fire safety needs factoring in too, especially for extensions with two storeys or more.
If it’s extra space you’re after and you have an emotional attachment to your home, why leave it? With a double storey extension from Clearview, you can create a thrilling new area to make memories in and prolong your stay. Savour the infinite day to day benefits of a home extension masterminded by you and the region’s doyen of extension designs, Clearview.
In its current form, your home may lack the space to accommodate e.g., an extra dining area or home office. Extending will see to that and can serve as just about any kind of room.
We accumulate lots of belongings the longer we reside in a home, and it may be pushing yours to its limit. An extension will take the pressure off other rooms for housing vital and treasured possessions.
You’re in control of how the extension is configured and the personal touches it incorporates, inside and out, as Clearview lets its customers tailor their house extensions to their taste.
Assimilating an extension into a property invariably adds immense value and can motivate buyers into paying more to secure it. As a rough estimate, it can boost the sales valuation of homes by around 20%.
Clearview is proud to be one of the few home improvement firms to hold both CHAS and Constructiononline accreditations, typically awarded to major construction firms. These certifications underscore our commitment to safety, quality, and operational excellence.
