Our know-how with renovations and refurbishments in commercial and domestic settings.

As a leading construction company that provides exceptionally high levels of attention to detail, much of our workmanship can be found on show within our housebuilding and extension projects.

Perhaps you would like to make the most of the space you have in your loft cavity to turn it into a space you can use as an extra bedroom with an en-suite, for example? Maybe you would like to remove an internal wall to connect your kitchen more directly to your dining room in an open-plan layout? There again, maybe you run a retail business and need a professional fit-out company to completely alter the look and feel of the shopping experience your customers will feel when they come in? 

Whatever your reason for seeking a refurbishment of your property, we have the experience to deliver. Please note that this work also includes renovating and updating older or poorly maintained properties so that they meet modern building standards and lifestyle expectations.

Here at Lanext Construction, we have been working with energy-efficient doors and windows, low-carbon concrete suppliers, LED lighting and green underfloor heating systems for years. As such, we can pass on the benefit of our experience and provide you with a high-quality installation of these sorts of features as we have dealt with them many times in the past before.
