Glazed extensions

With the uncertainty of the property market, adding a glazed extension is a cost-effective way to increase the living area at the same time as adding value to your home.

The cost of moving house in the UK is on the rise, and many homeowners are improving the house they currently have by as an alternative to selling up and moving.

There are many types, styles and size options of glazed extension available.

With orangeries you can enjoy the light from a glazed roof lantern, providing a light and spacious extension.

Alternatively, a conservatory can be as slightly less costly option. This will be a predominantly glazed structure, although features such as ‘Livin Room’ and ‘LivinRoof‘ can be incorporated to provide part-glazed, part-solid insulated roof options.

Whatever your preference, if you are looking out the window at the grim winter weather and already dreaming of enjoying the summer sunshine in a brand-new conservatory or orangery, the time to start planning is now.

Taking into account the time sign off a design, needing to obtain planning permission, carrying out the installation and then adding the finishing touches, it can be a months-long process!

At Window Wise we have considerable experience in the design and construction of the smallest and most simple conservatories and orangeries to the largest and most elaborate.
