Why Home Extensions In Preston Make Sense
Preston is one of Lancashire’s most dynamic cities. With the University of Central Lancashire bringing a steady flow of young professionals into the area, and established families putting down roots in neighbourhoods like Penwortham, Fulwood, and Lea, demand for quality housing continues
to grow. Rather than facing the cost and upheaval of moving – stamp duty, solicitor fees, months of uncertainty – more and more Preston homeowners are choosing to extend. It is a decision that makes real financial sense.
A well-executed house extension in Preston can add significant value to your property while giving you exactly the space you need, designed exactly the way you want it.
Preston’s housing stock is wonderfully varied, and that variety is something we embrace. The solid-brick Victorian terraces found around the city centre and Winckley Square conservation area often have generous plots with real scope for rear or side-return extensions. Meanwhile, the 1950s and
60s semis across Fulwood and Ribbleton frequently benefit from single-storey or wrap-around extensions that completely open up the ground floor.
Whatever your property type, extending your Preston home means you get to stay in the
neighbourhood you love, keep the kids in their school, and hold on to the community connections
that matter.

The Right Extension for Your Preston Home
Every home is different, and every family has different needs. We offer a full range of extension types, each one tailored to your property and your lifestyle.
Single-Storey Extensions
The most popular choice for Preston homeowners, single-storey extensions are ideal for creating open-plan kitchen-diners, larger living rooms, or ground-floor home offices. For the many Victorian terraces in Preston, a rear single-storey extension can completely transform a narrow galley kitchen into a bright, sociable family space. Most single-storey extensions in Preston fall within permitted development rights, meaning you may not even need full planning permission.
Two-Storey Extensions
If you need space on both floors - perhaps a bigger kitchen below and an additional bedroom or bathroom above - a two-storey extension delivers outstanding value for money. The cost per square metre drops significantly compared to building single-storey, and the impact on your property value is substantial. Two-storey extensions work particularly well on Preston's detached and semi- detached homes in areas like Fulwood and Ingol.
Wrap-Around Extensions
Combining a rear and side extension into one continuous space, wrap-around extensions create truly impressive open-plan living areas. They are a brilliant option for Preston corner plots and properties with side access, and they make a dramatic difference to how your home feels and flows.
Orangeries & Garden Rooms
For something that sits between a traditional extension and a conservatory, our orangeries and garden rooms offer a light-filled living space with real architectural presence. Built with solid walls, lantern roofs, and A-rated glazing, they provide comfortable year-round use - nothing like the old- fashioned conservatories that are too hot in summer and freezing in winter.

What Our Extension Customers Say
Wow! What can we say. Just had our double hipped conservatory roof replaced with a Guardian solid roof by Carrick & his team. The whole process ran like clock work. They arrived on time every day, materials were delivered day one & a great pair of lads (Jake & Ryan) working like 'trojans' each day. Completed quickly with minimum mess, with additional trades organised by Carrick arriving promptly when required. They even cleaned the conservatory down when finished. Seriously pleased with this project & without doubt a 100% recommendation. Our only issue...? We should have done this long ago. Conservatory now feels like an extension rather than a big 'greenhouse'. Both myself & 'Mrs P' are thrilled to bits. Thanks team CSG Plastics & build Ltd. 10 out of 10... Brilliant job & very professional.
Absolutely brilliant service! He came out quickly and fixed my window with no hassle at all. Super friendly, professional, and clearly knows what he's doing. The job was done quickly & efficiently. Really appreciate the effort and would 100% recommend to anyone needing window repairs. Thank you again!
Very professional + even carried out an additional job that wasn't on the to-do list. Would highly recommend & thanks once again!
Really good job and very reasonable price. Will definitely use again.
We have just had our old conservatory roof replaced with a new solid insulated Guardian roof by Carrick at CSG Plastics. The work was carried out by Jake and Ryan, who were on time every morning, polite and did a superb job in a most efficient and timely manner. Attention to detail, no mess, along with regular updates and communication from Carrick was a breath of fresh air and made the whole project stress free. Without hesitation, I would thoroughly recommend CSG Plastics. Thank you guys, Julie and I are so happy with our cosy conservatory.
Excellent attention to detail. From the outset of site survey a solution was found at the right price for what I wanted to achieve, would recommend.
Carrick and his team did a first class job installing new windows, & replacement porch roof. All work carried out to an excellent standard, now several months on and no problems have arisen. Will certainly recommend and use in future.
We are very pleased with our soffits, facias and guttering completed just before Christmas 2021. Jake and Josh did a great job. There were a couple of hiccups, but they were sorted quickly by Carrick. Thanks a lot, and best wishes for 2022.
