Side Extensions in Barry

Space Beside Your Home

Make Even More Space Beside Your Home

A side extension uses the space beside your home to create a wider kitchen or living area. Cooksey Renovation carefully reviews the plot, build access and connection to existing rooms, then coordinates the agreed work from start to finish, with Lance as your main contact throughout.

Room for a Wider Layout

Use suitable space beside the house to widen a kitchen, dining area or living room around how you use it.

Access Considered Early

Review the side passage, drains and access early, including whether a route to the garden needs to remain.

One Contact for the Build

Lance coordinates all building work and trades, from foundations and shell to fitting and making good.

Agreed Scope

What Your Side Extension Includes

Your quote defines the agreed building work, connection to the house and finishes, based on the side space and required design.

Kitchen and Room Layout

A side extension can widen a kitchen, dining area or living room. A side return uses the strip beside a rear projection. Plan storage, furniture and routes through the enlarged room, including any garden access you want to retain.

Access, Drains and Groundwork

Narrow access affects deliveries, excavation and waste removal. Existing drains and services in the side passage need to be identified, with the foundations and any alterations following the required design and agreed scope.

Roof, Light and Connections

Plan rooflights, glazing and roof shape around daylight in the new space and existing rooms. Materials and junctions should suit the house, with roofing, drainage, insulation and making good included as specified in the quote.

Boundary Considerations

The design accounts for boundaries and neighbouring structures. Boundary building, party wall work or nearby excavation may bring the Party Wall Act into play. Any required notices and procedures are addressed before the relevant work starts.

Discuss the Gap and the Access

At the visit, we look at the side space, access and existing rooms. We discuss the proposed layout and identify the design information, drain checks and boundary considerations needed for the scope.

Before We Start

Cost, Timing and Planning

Side extension cost and timing depend on the width, ground conditions, access, drains and connection to the house, alongside the agreed finishes.

What Shapes the Price

The quote considers the width, ground conditions, drains and construction access. Roof choices, the connection to the house and interior specification also shape the price.

What Shapes the Timeline

The programme allows for design, approvals and any required party wall procedures. Access, shell construction, service changes and fitting then shape the build sequence.

Check the Side Space and Boundaries

Welsh planning checks consider side extension width, height and proximity to boundaries or a highway. Building regulations and any party wall requirements are separate.

Renovation Examples

Ideas for Your Kitchen and Room

The gallery shows examples of Cooksey’s renovation work, including kitchen fitting and room preparation. Discuss these finishes when planning how the widened space should work inside.

Our Process

Check the Side Space Before the Build

Lance starts with a site visit to review the side space, access and room you want to widen. The required design identifies the connection to the house, drain alterations and boundary considerations. Planning, building regulations and any party wall procedures are addressed before relevant work starts. The shell is followed by services, fitting and making good, with Lance coordinating the agreed trades and keeping you updated.

Helpful Answers

Before You Build Beside the House

These answers cover side returns, neighbouring boundaries and layout choices when planning how to use the space beside your home for a practical, well-planned extension layout.

Side return or wraparound extension?

A side return fills the strip beside a rear projection. A wraparound also extends across the rear. The house, available space and required design determine which layout may be suitable.

Could the work need approval?

Welsh permitted development limits and conditions determine whether planning permission is needed. Building regulations are separate, and most extensions require approval. Read how construction work on a home is managed before a start date is set.

What if a neighbour's wall is close?

Work at a boundary, on a party wall or involving nearby excavation may fall under the Party Wall Act. Whether it applies is checked for the proposed work, with required notices and procedures addressed before starting.

Should I consider a rear extension?

It depends on the space around the house and room you want to create. Compare a single-storey rear addition with widening at the side, considering garden space, access and the connection to existing rooms.

 Trustindex verifies that the original source of the review is Google. Huge thank you to Lance and the team for their great work on our full bathroom renovation!

Our old house threw up so many extra problems to work around, but the guys kept us well informed and worked hard to overcome everything

They truly brought my vision of a modern meets vintage bathroom to life

I'm especially obsessed with the tiling work, the detail and the effort for all those extra little touches make the room look so fab

I am absolutely over the moon with how it's turned out! Thank you thank you thank you!

Covered every aspect of the installation of a new bathroom from liasing  with suppliers to the electrics , plastering and tiling. Highly recommended

 Trustindex verifies that the original source of the review is Google. We cannot recommend Lance and the team enough. From beginning to end him and the team were professional, knowledgeable and communicative.

Lance did multiple visits to us before starting work to ensure the best end result, our bathroom was a difficult refurbishment to say the least, but the final result is a testament to Lance and the teams skill and determination.

When the work was being completed they were clean and tidy, often worked incredibly long days and kept me informed on any changes or challenges. He worked with us to keep to our budget updated us on any additional material charges.

My neighbour even commented on how friendly and polite they all were.

I have already recommended Lance to multiple people but will also have them back for any other renovation we need completing in the future. I wouldn't go with anyone else now.

 Trustindex verifies that the original source of the review is Google. Recently had our Bathroom renovated by Cooksey Renovation; they did a fantastic job throughout and transformed our bathroom!
The quality of their work is to a very high standard. They arrived on the agreed date to commence the renovation, were on time every morning, cleaned up after them every evening, and were pleasant and communicative throughout.
I can’t recommend this company highly enough and would certainly use them again or recommend them to friends and family.

 Trustindex verifies that the original source of the review is Google. Cooksey renovations and the team did an amazing job with our new kitchen and flooring. The job needed blocking up doors, windows and a fair bit of plastering.  They were all really tidy and cleaned up after each day before they left. I'm so happy with the work they have done. Thank you!

 Trustindex verifies that the original source of the review is Google. I cannot recommend Lance and his team enough! They have renovated both my bathroom and en-suite as well as repairing and replastering my living room ceiling following existing water damage.
When I moved into my house, I knew there was gonna be a lot of work to do following previous leaks in the en suite and previous bad workmanship. All the team were professional, trustworthy and skilled in how they transformed my house. They kept everything clean and tidy (I even caught them hoovering my doorstep at one stage!) and made the house useable in between their working days. I had a very specific vision and they were able to make my dreams come to life and I’m so pleased with the end result.
They ripped out my old suites, replaced rotten floor boards, rebuilt damaged walls and install all new paperwork. Nothing was too much trouble and they were also the most competitive quote I received.
I have a kitchen and artexed ceilings to be renovated in the new year and there is no one else I would consider using.
Thanks guys! I really love what you’ve done!

 Trustindex verifies that the original source of the review is Google. A return visit by Cooksey renovations to tile the floor of 3 existing bathrooms that didn’t need a complete re fitting.

The work was to the highest  and we are delighted with the end result. We  have no reservations in recommending Cooksey renovations for this type of work.
