Need More Space but Love Where You Live?
A house extension makes your home work better without leaving the area you know and love.
Whether you need more room for family life, a larger kitchen, an extra bedroom, or a better layout, the right extension can completely change how your home feels and functions.
But it is still a big investment, and you want to feel confident you are making the right decisions. You want a builder who communicates clearly, gives honest advice, and takes real pride in delivering a high-quality finish. That peace of mind matters just as much as the extra space itself.
At Corcrin Construction, we help homeowners extend with confidence. With over 35 years of hands-on experience, we deliver house extensions that feel well built, well managed, and thoughtfully finished from start to finish.
Benefits of a House Extension
Create More Space Without Moving
If you need more room but do not want the stress, cost, and upheaval of relocating, an extension can give you the extra space you need while staying in the home and area you already love.
Improve the Way Your Home Works
An extension is not just about adding square footage. It is a chance to improve flow, bring in more light, create better connections between rooms, and make everyday life feel easier.
Adapt Your Home to Changing Needs
As life changes, your home may need to change too. Whether your family is growing, you need space to work from home, or you want room for guests or multi-generational living, an extension gives you flexibility for the future.
Add Value to Your Property
A well-designed, well-built extension can add long-term value to your home while also making it more enjoyable to live in right now.
Different Types of House Extensions
Single-Storey Extensions
A popular option for creating larger kitchens, dining areas, utility rooms, or extra living space at ground-floor level.
Two-Storey Extensions
Ideal when you need more space both upstairs and downstairs, such as adding extra bedrooms, bathrooms, and larger living areas in one project.
Kitchen Extensions
Perfect if your kitchen feels cramped or outdated and you want a brighter, larger, more practical heart of the home.
Attic Conversions
A smart way to create extra living space without extending the footprint of your home. An attic conversion can be ideal for an additional bedroom, home office, playroom, or guest space, while making better use of the room you already have.
Garage Conversions
If your garage is underused, converting it can be a practical way to add valuable living space without major structural expansion. It can work well as a home office, extra bedroom, utility space, or additional family room, depending on your needs.
Rear Extensions
A great way to open up the back of the house and create a more spacious kitchen, dining, or family area connected to the garden.
Not every type of extension suits every property, which is why good planning and honest advice matter.
We can help you understand what works best for your home, your space, and your family.

We Work with Your Architect
Not every house extension needs an architect, but if you already have one, we are very happy to work alongside them to bring your plans to life. Good communication between the homeowner, builder, and architect can make the project run more smoothly and help avoid unnecessary stress along the way.
How we work with your architect:
Reviewing drawings and build details
Providing pricing based on plans
Clarifying practical construction requirements
Coordinating during the build
Helping turn the design into a high-quality finished home
If you are still at the early stage and are not sure whether you need an architect, we can talk through your ideas and help point you in the right direction.
How to Get Started
If you are thinking about adding a house extension, these are the main steps most homeowners go through:
1
Think about how you want the extra space to work
Start by being clear on what you need from the extension, whether that is a bigger kitchen, extra living space, another bedroom, or a better layout.
2
Check what might suit your property
The size, shape, and position of your home and garden will help determine what kind of extension is possible.
3
Speak to an architect or designer if needed
For some extensions, professional drawings will be needed to help develop the design and move the project forward.
4
Check planning permission and building requirements
Some extensions may require planning permission, while others may not. It is important to understand what applies before work begins.
5
Set a budget
Having a realistic budget from the start helps make sure the design and scope align with what you want to achieve.
6
Find the right building contractor
Choose a builder with experience, a strong reputation, and a clear focus on quality, communication, and doing the job properly.
House Extensions Frequently Asked Questions
Do I need planning permission for a house extension?
It depends on the size, type, and location of the extension. Some projects may require planning permission, while others may fall within exempted development. It is always best to check early before moving ahead.
Do I need an architect for a house extension?
Not always. Some extensions are more straightforward than others. If drawings or planning are required, an architect or designer may be needed. If you already have one, we are happy to work with them.
Can you quote from drawings?
Yes. If you already have plans or drawings prepared, we can review them and provide a free, no-obligation quote.
How much does a house extension cost?
That depends on the size of the extension, the level of finish, structural requirements, and the complexity of the work. We can help you get a clearer idea once we understand your plans.
How long does a house extension take?
That depends on the scale and complexity of the extension. Smaller projects will move more quickly, while larger or more complex builds may take longer.
Will the extension match the rest of my house?
That is always the goal. A well-built extension should feel like a natural part of the home, not something that looks added on as an afterthought.
