Loggia LivinROOF Extension

The Harlington plus extension is renowned for being the most versatile building regulation compliant product in the entire market! This extension choice is guaranteed to provide excellent thermal efficiency with built-in Loggia Super Insulating Columns and features the LivinROOF additional feature which is a thermal plastered roofing system guaranteed to provide a much cosier and room-like feel. This is the perfect solution if you are looking to create a warm comfortable cinema room, an office or a playroom.

All our extension designers and installers are fully vetted and we include a FREE Insurance Backed Guarantee every time.

The Perfect Winter Comfort Solution

We have developed a Harlington plus extension that can easily be adapted to fit any existing structure, large or small, vintage or brand new. You can choose Classic PVC and rest assured knowing that it is successful at providing total durability and waterproofing.

We have a variety of roof style options including Georgian, Lean To and T-Shape; the Harlington plus extension has a solid roof but if you fancy a few stylish glass panes to increase sunlight and visibility, this is not a problem. You can also decide whether you want the connecting doors to remain or not.

Virtual Design

You don’t have to wait until your Harlington plus extension is built to see how it will look! We will provide you with a FREE visual representation on-site and you can choose which features you would like to add and where! With the Harlington plus extension you can now choose a building shape and style to suit your personal preference. One of our experts will talk you through your options and make suggestions relating to where you can make improvements.

Once you are happy for us to begin the build we will get to work at a time most convenient for you. It is that simple!
