Your Local Experts for Quality Home Extensions in Preston
Is your Preston home starting to feel a little too snug?
Whether you’re working from a corner of the kitchen table, need a bigger space for family dinners, or your growing family simply needs another bedroom, a well-planned house extension could be the answer. Preston is a city we know inside out. From the elegant Victorian terraces near Winckley Square to the popular post-war semis across Fulwood and Ashton, we understand how Preston homes are built and what it takes to extend them properly. Every property has its own character, its own quirks, and its own potential – and we love helping homeowners unlock that potential.
At CSG Plastics & Build, we have been designing and building home extensions in Preston andacross Lancashire since 2010. As a family-run business with over 175 five-star reviews, we take genuine pride in every single project we deliver.
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.
