Glasspace are experts in the design, manufacture, and installation of structural glass solutions. Award-winning architects and engineers have developed Glasspace structures using commercial glazing technology to create a contemporary environment that exceeds the demands and expectations of modern day living.

Glazing technology has allowed us to develop the highestspecification glass products including laminated glass, beams, floors, stairs and much more. High specification thermally low-e structural double and triple-glazed units over u-values as low as 08, warm edge spacer technology, and argon gas filed units, help us to achieve this.

Glasspace are recognised within the industry for designing some of the most ground-breaking structures with the commercial and residential marketplace.

Glasspace have developed their Infiniti structural sliding doors which, with sight lines of 17mm and heights of up to 4000mm, are becoming the architect’s choice when designing contemporary living environments.

“Our projects are never ‘standard’ yet so often glass companies try and use standard systems and fittings – this only ever results in details which draw your attention for all the wrong reasons. Glasspace are different, for all the right reasons, they use bespoke solutions backed-up by the latest technology, tried and tested suppliers and years of experience to deliver beautifully detailed glass. Glasspace is the architects’ choice because architects love glass – this pure and elegant material must be handled correctly so you see less and gain more. No other glass company I have worked with delivers more on making glass reality as beautiful as the concept design.”

Welcome To GlasSpace - Architectural Glass & Structural Glazing Specialists

As a market leader, at GlasSpace we are an award-winning structural glazing company known for our revolutionary frameless glazed extensions, structural frameless glass conservatories, floating glass staircases, glass floors and much more.

Our structural glass systems bring the benefits of traditional extensions such as extra space, high thermal efficiency and increased property values as well as letting natural light flood into your home. They introduce interesting structural glazing features to merge homes and gardens for modern living at its best. Bring a touch of class and elegance to your home with one of our contemporary glass porch designs or stunning modern glass wall facades.

Working with light and space, our specialists create modern structural glass installations that sit within your existing living environment old or new. Transform your home, we can create a seamless design whether it’s a frameless glass conservatory or a glass kitchen extension. All our structural glazing systems are bespoke and to each individual project manufactured and guaranteed.

Modern glass architecture is becoming increasingly popular within the UK. There are many different types of architectural glass systems to use. Clear frameless

structures create no borders between your outside space and living area this can help bring the beauty of the outside into your home, helping create a healthier living lifestyle. However, if you prefer a frame for your structural glazing we also supply stainless steel fittings. Our steel framed windows and doors are a popular choice among architects.

Featuring in many home improvement magazines, we set the standard in modern-day living by utilising the latest specifications in thermal insulation and solar-controlled glass panels. These are custom-built for your energy efficient glass room extensions for your home. Your GlasSpace structural glazing is guaranteed to exceed the rigorous new heat efficiency regulations and remain comfortably warm even in the most extreme conditions.

The technology in the solar-controlled glass systems that we use means that you can keep the internal temperature ‘just right at all times – no more ‘too hot in the summer’ and ‘too cold’ in the winter, we can support this with test results and testimonials. Our installations are eco-friendly – helping reduce both your energy bills and carbon emissions. Building a glass box extension will also add value to your property. Check out our portfolio of recent projects for some inspiration!

Our process is easy and simple

Working with our designers and structural glazing engineers at GlasSpace we believe we have put in place a system that allows us to create and manage your architectural glass room or extension.

Building a bespoke GlasSpace extension or contemporary glass conservatory onto a new or old property needs accurate surveys that give all the information required to design and calculate your structural glass room/staircase floor or glass flat roof skylight.
