The Ultimate Guide to Home Extensions in Lancashire 2026
If you’re a homeowner in Preston, Fulwood, Broughton, Penwortham, Standish, Ormskirk, Eccleston or anywhere across Lancashire and you’re thinking about extending your home in 2026, this guide is for you.
See recent Extensions built in all those areas and across Lancashire on our dedicated Case Studies page.
Home extensions remain one of the most popular ways to gain extra living space without the stress and expense of moving. With rising house prices, growing families, and the desire for modern open-plan living, more Lancashire homeowners than ever are choosing to extend rather than relocate.
At Price & Price Building Ltd, we’ve been helping families across Lancashire create beautiful, high-quality extensions for over 20 years. In this ultimate guide, we cover everything you need to know about home extensions in Lancashire in 2026 — from types and costs to planning rules, timelines, and how to choose the right builder.
Why Home Extensions Are So Popular in Lancashire Right Now
Lancashire homeowners are extending for many reasons:
- Growing families needing more bedrooms or living space
- The desire for open-plan kitchen-diner-living areas
- Working from home and needing a proper office or studio
- Adding value to the property before selling
- Avoiding the high costs and disruption of moving house
Extending your home in 2026 is often more cost-effective than moving, especially when you factor in stamp duty, estate agent fees, and the stress of relocation.
Types of Home Extensions in Lancashire
Here are the most common types of extensions we build across Preston and Lancashire:
Single Storey Extensions
The most popular choice in Lancashire. Ideal for adding a larger kitchen, open-plan living space, or home office. They are usually quicker to build, more affordable, and often fall under permitted development rights.
Double Storey / Multi-Storey Extensions
Perfect when you need extra bedrooms and bathrooms. These offer excellent value per square metre because the foundations and roof are shared. Great for growing families in Fulwood, Penwortham, and Standish.
Open Plan Kitchen Extensions
One of the biggest trends in 2026. These extensions combine kitchen, dining, and living areas with large bi-fold or sliding doors that connect to the garden. Extremely popular in Broughton, Ormskirk, and Eccleston.
Kitchen Extensions
Dedicated kitchen extensions remain very common. They allow for a much larger kitchen with an island, better storage, and direct garden access — transforming how families live and entertain.
Side and Rear Extensions
Depending on your property, side or rear extensions can be the best way to maximise space while respecting the character of traditional Lancashire homes.

Planning Permission & Permitted Development in Lancashire 2026
One of the first questions we get asked is: “Do I need planning permission?”
Many single-storey rear extensions in Lancashire can be built under Permitted Development rights, meaning you don’t need full planning permission. However, there are strict rules on size, height, and proximity to boundaries.
Key points for 2026:
- Single-storey rear extensions up to certain depths often qualify.
- Side extensions and two-storey extensions usually require planning permission.
- Properties in conservation areas (such as parts of Fulwood and Standish) have stricter rules.
- You may still need Building Regulations approval even if planning permission isn’t required.
At Price & Price, we assess your property and advise you on the best route — whether that’s permitted development, a Lawful Development Certificate, or a full planning application. We handle the entire process for you.
How Much Does a Home Extension Cost in Lancashire in 2026?

- Kitchen extensions: £2,200 – £3,000+ per m²

We design and build extensions that not only meet these regulations but often exceed them — helping you reduce running costs and future-proof your home.
