Glass Extension to a Listed Cottage in a Conservation Ares

A modern glass kitchen extension has been built onto this listed cottage in the countryside to create an open plan living space. By adding the glass box extension which utilises structural glazing and slim aluminium doors, it has allowed the kitchen to be naturally lit throughout the day as well as adding a modern touch to the old brick cottage.

Minimally framed glass sliding door units were installed onto this extension to create an open plan kitchen and allow seamless access into the garden. These glass doors have a 21mm frame to perfectly match the sightlines of the structural glass walls that make up the majority of this glass box extension design. 

These glass doors and frameless glass walls create an indoor-outdoor living space by merging the kitchen with the patio area, perfect for access for the homeowners who want to want to eat outside during the summer months.

An inward opening aluminium pivot door was specified within the extension, acting as a traffic door. To merge the thicker framed door opening into the design of the minimal extension and appease planning officials who required a sleek glass design, the glass within the door was stepped over the outside edge of the aluminium door to create a flush, all-glass external finish.


The structural glass of the glass extension was stepped over the roof structure above to create a continuous glass façade to the extension and a fully glazed design. The glass was then back painted black to hide all structure and supports behind.

The backpainted glass creates a contrast against the heritage stonework of this listed cottage, which makes up the majority of the cottage's exterior design, as well as the clear glass. The added detail makes this listed building one of our most popular extension designs, featured in many publications since its completion.
