Introduction
The right extension starts with the right team.
An extension is one of the biggest investments you'll make in your home. If the wrong team is managing it, the cost goes far beyond the quote. Delays, unfinished work, poor communication and expensive mistakes can quickly turn an exciting project into months of unnecessary stress.
That's why we built Renex differently. Backed by over 15 years of construction experience, we've combined quality building work with a customer-first approach to project management that keeps your extension organised, your project moving and you informed from the first conversation to the final handover.

Extensions we build.
Single-storey, garage conversions, loft extensions. We've got your back no matter the project.
Rear Extensions
Extend your home into the garden with a rear extension designed around the way you live. Whether you're creating a larger kitchen, dining area or open-plan family space, we'll help you plan, manage and deliver your project with confidence from day one.
Side Extensions
Unlock the unused space beside your home with a side extension that creates valuable additional living space without changing where you live. From planning through to completion, we'll keep your project organised, on track and moving forward with confidence.
Wrap-Around Extensions
Combine the benefits of a rear and side extension to completely transform the way your home works. We'll help you plan, manage and deliver your project with confidence from day one.
Double Storey Extensions
Expand your home across two floors to create the additional space your family needs today and for years to come. With careful planning, experienced project management and clear communication throughout, we'll deliver your extension with confidence from start to finish.
Garage Conversions
Transform an underused garage into practical living space without increasing the footprint of your home. Whether you're creating a home office, additional bedroom or family room, we'll guide your project from the first conversation to the final handover.
Loft Conversions
Make the most of your existing home by converting unused roof space into a bright, practical new room. We'll help you unlock your home's potential with a carefully managed project from start to finish.
Our Extension Process
Extensions are difficult. Our process keeps it simple.
Building an extension doesn't have to feel uncertain. Our structured process keeps your project organised, keeps you informed and makes sure you always know what happens next.
(01)
Home Visit
We'll visit your home, understand what you're looking to achieve and talk through the options available. You'll receive honest advice, practical recommendations and a clear understanding of what's possible before making any decisions.
(02)
Planning
Once we've agreed the direction, we'll provide a detailed quotation, project plan and realistic timescales so you know exactly what's included before work begins.
(03)
Construction
Your extension gets underway with one experienced team managing the project from start to finish. You'll receive regular updates, clear communication and complete visibility throughout the build.
(04)
Handover
Before we leave, we'll walk through every part of the project together, making sure everything meets the standard we promised and you're completely happy with the finished result.
Client Portal
Keep track and stay organised throughout the extension build
An extension isn't something that happens overnight. Documents, schedules, updates and key milestones all build up throughout the project. Your Client Portal keeps everything organised in one place, so you always know where your project stands and what's coming next.
