Why flat pack is an advantage?

The new extension replaced a very old conservatory that was too hot in summer and too cold in winter. Our client wanted the extension to feel seamless – like a real part of the family home, and to be comfortable year-round.

Before installation could commence, the existing conservatory was removed to make space for the new SIPS extension, including removing the existing concrete slab foundation and liaising with a local builder to ensure existing drainage was routed correctly to outside the footprint of the new building.

Not ones for waste, the Vivid Green team removed existing windows from the main house and actually reused these in the final design. This preparation work provided us with a blank canvas to start the SIPS extension installation.

Bright and light garden room extensions

The main requirements were 2-fold. The desired extension needed to be as big as possible, while keeping within permitted development regulations, and the new design was to be a light and bright building that matched the existing house, within reason, but more than that aesthetically enhanced its external look.

We achieved the ‘light and bright’ element of the client’s brief by including two large skylights, a double side window (part of the original house) and glass patio doors with two full-length windows on either side of the patio doors. This captured light from all elevations.

Climate control was also installed to heat and cool the new building, as necessary. The new internal layout was given much consideration and the final request was to create a new doorway on the left to knock through to the existing utility room.
