Completed Spectrum installation
This Colchester project shows a conservatory converted into a hup! extension. Use the case study to understand the completed layout, then discuss what can be retained at your own home. Existing bases and openings need assessment before the structure, roof and associated work are agreed.
This project is shown at its actual location as a reference for your Wivenhoe enquiry.

Before you choose
A new room can change how the rest of the home works. Consider doorways, sightlines and furniture before deciding on the footprint, then identify the structural work, services and finishing that need to be included.
