A smarter way to extend residential properties

At Listers, we supply Extensions Plus to installers across the UK. Choose from our beautiful Ultraframe Extensions Plus range to create and enhance the space within a customer’s home. Give your customers a new dining room, lounge, study or office with Extension Plus.

Extensions Plus takes a different, more advanced approach to adding space to a home. It’s a simple, flexible system that cleverly uses pre-designed, pre-engineered and pre-approved components without compromising on space and durability. Extensions Plus can be installed quickly, with minimal hassle and mess, leaving your customers satisfied and able to quickly move on with their day to day business.

At the heart of Extensions Plus are the innovative corner columns. They not only give your customer’s extension an enhanced level of strength and solidity, but are constructed around a highly insulated core. This core ensures homeowners can enjoy extensions which are 5 times more thermally efficient than those fitted with a similar sized brick column.

Extensions Plus are engineered using a combination of a uPVC framework, with double glazed glazed windows and a choice of external doors. This first step to a true extension reaches impressive levels of energy efficiency, coming in at just 1.0W/m²K as standard. These builds can be customised to suit a variety of property styles and sizes. All the options supplied by Listers will enhance the natural light and comfort of the home, whilst still offering security and thermal efficiency.
