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.

How thermally efficient are extensions?
Our extensions are built to offer energy efficiency ratings of up to ‘A++’ while lowering the U-values of your property in the Andover and Hampshire areas.

How long are extensions built to last for?
Using designs manufactured and created to last, our extensions have been vigorously tested for customer satisfaction. Combining regular low maintenance cleaning and additions such as self cleaning glass, our house extensions can last for years, even at standard design.
What glazing types are available for extensions?
With the design specification of full or partial glass on our extensions, you can customise the glazing to meet your needs. Choose between double or triple glazing for increased thermal performance. Also, choose between designs that provide privacy or remove sightlines to your extension.
