Home Extensions

KHL Constructions Ltd® specialise in single storey, one or two room, contemporary house extensions (similar to conservatories or sun lounges), but with solid walls and roofs, allowing you to enjoy the space 365 days a year. We can even create you a 2 or 3 metre opening at the back or side of your house if existing openings do not exist.

  • Fast Construction Time (3-6 weeks) – Unlike many other building companies your floor, walls and roof will be constructed on-site.
  • No Planning Permission Required – your home extension will meet all current building regulations and most do not require planning permission.
  • Complete Design, Fabrication and Installation Service – at KHL® we provide a complete service from the initial design through to installation in a quick and painless manner.
  • 10 Year Guarantee!


We are confident that no one is better placed to advise on how best to extend your home, to add value, and make best use of the space & the existing layout. We offer a professionalism & attention to detail that we believe is unmatched. We take great care to plan our work to cause minimum impact on the householders, and research materials carefully to ensure the best possible match. All of this with our own team, and professional Management.
