Sliding patio doors move alongside another panel, which can help where furniture or garden space is close to the opening. Our Wivenhoe service compares the view when closed with the access available when open. The Wivenhoe Comp Door project began with an entrance that was no longer usable.

This Colchester project combines a skylight with Visoglide sliding doors. Compare the balance of fixed and moving panes with the view from inside your room. Discuss handle access, the clear walk-through opening and how the door track meets the floor and outside paving.
This project is shown at its actual location as a reference for your Wivenhoe enquiry.
