Customisation Options

Working closely with Ultraframe, we can use and install a selection of their high quality extension designs. Choose from flat roof, Livinroof or Ultraroof designs to find and tailor to meet your tastes and needs.

Using these designs as bases, you can upgrade your extension by changing windows, doors, glazing designs, hardware and locking systems. Alternatively, opt in for blinds, light and speaker systems or underfloor heating. For product photographs of our installed extensions, view our product gallery.
