House Extensions in Carmarthenshire – Designed for Your Lifestyle
Looking to add more space, value and comfort to your home? At Wren Construction, we specialise in building high-quality, custom-designed house extensions across Carmarthenshire and throughout Wales. Whether you need a larger kitchen, an extra bedroom, a home office or a stylish open-plan living area, our team will work with you to create a custom extension plan that meets your needs and vision, using quality materials and experienced workmanship.
Create the Home You’ve Always Wanted
Extending your home is a fantastic way to adapt your space to suit your changing lifestyle. From growing families to remote working needs, more homeowners are choosing to stay and improve rather than sell and move.
At Wren Construction, we make that possible with seamless, stress-free building services tailored to your property, budget and goals.

Rear extensions designed to create larger kitchens, dining rooms and family spaces.
Side Return Extensions
Make better use of underused side space and improve the layout of your home.
Double-Storey Extensions

Wrap-Around Extensions
Combine rear and side extensions to create a major transformation.
Kitchen Extensions

Conversions & Additions

No matter the size or complexity, we approach every project with the same commitment to quality, detail and communication. From the initial design and planning permissions to construction and final finishing, we’re with you every step of the way.
House Extensions Tailored to Your Needs
Every home – and every family – is different. That’s why our experienced team takes the time to understand your needs, your lifestyle and your property layout before recommending the right solution.

The Benefits of a House Extension
A house extension is one of the best ways to enhance your home’s space, usability and value without the cost and hassle of moving.
Increase Your Living Space
Ideal for modern lifestyles, growing families and changing needs.
Improve Property Value
A well-designed extension can make your home more attractive and useful to future buyers.

Stay in the home and location you already know while gaining the extra space you need.
Tailored to Your Lifestyle

Planning, Permissions & Building Regulations
We understand that the process can feel overwhelming, but we help guide the project from the early stages through to completion.
In many cases, extensions may fall under Permitted Development Rights, especially for certain single-storey rear additions. We’ll help you understand what may apply to your property and keep the project compliant at every stage.
