Trending Glass and Timber Extension Designs


Glass and timber extensions offer a harmonious blend of contemporary design and natural aesthetics, seamlessly integrating modern living spaces with the surrounding landscape.  
Glass, with its transparency and ability to flood interiors with natural light, creates a sense of openness and connectivity to the outdoors, while timber adds warmth, texture, and a touch of organic charm.  
Achievable in a number of configurations, glass and timber extensions often serve as versatile spaces, allowing dwellers to enjoy panoramic views and immerse themselves in the beauty of nature while remaining sheltered from the elements. 


Timber Supports in Glass Extensions

Glass extensions supported by timber structures offer a captivating architectural juxtaposition, blending the sleekness of modern design with the timeless elegance of natural materials.

Timber supports provide both structural integrity and visual interest, creating a sense of warmth within a contemporary space. These supports can be intricately designed, showcasing the beauty of wood grain and the craftsmanship of joinery, while also serving as functional elements that bear the weight of the glass panels.

This combination of glass and timber in extensions not only invites abundant natural light into the interior living spaces but also establishes a harmonious relationship between the built environment and the surrounding landscape, creating a tranquil retreat that seamlessly merges indoor and outdoor living. 



Timber Framed Windows and Doors 

Timber-framed windows and doors continue this synthesis of traditional building materials and contemporary design. 

By incorporating timber framed windows and doors into glass extensions, occupants can enjoy the benefits of abundant natural light, seamless indoor-outdoor transitions, and enhanced thermal performance. 

In glass extensions, the incorporation of timber framed doors brings significant advantages in terms of thermal performance.

As timber is a natural insulator, it can effectively prevent heat transfer between the interior and exterior environments. This insulation property helps to maintain a comfortable temperature within the extension, reducing the need for excessive heating or cooling and thereby lowering energy consumption.

Furthermore, timber's inherent durability ensures long-term structural integrity, providing reliable performance in maintaining thermal comfort over time.

Timber Cladding and Frameless Glazing 


Timber cladding, whether in the form of wall panels or slatted timber ceilings, creates a cozy and inviting atmosphere that effortlessly complements the transparency of the glass walls.

The rich textures and organic grain patterns of the wood bring a tactile element to the interior, adding depth and visual interest to the space. Moreover, timber cladding provides acoustic benefits, helping to absorb sound and reduce echoes, creating a more comfortable and tranquil environment.

In addition to its aesthetic appeal, interior timber cladding offers practical advantages as well, helping to regulate indoor temperatures and improve energy efficiency. This can be particularly beneficial in glass extensions, where maintaining thermal comfort can be a challenge due to the high levels of glazing.

Furthermore, timber cladding can be used to conceal structural elements or integrate storage solutions, maximizing the functionality of the space while maintaining a cohesive design aesthetic.
