We had a small side return extension installed by Glasspace and although only small, it has completely transformed the look and feel of our house. We are particularly happy with the guys who installed, they were very helpful and considerate.

Great service and on time we had a large house conversion with a glass extension to the side and rear of the house.

Our Arhitect worked with Glasspace on the final design and from start to finish it took 8 weeks.

The fitters were great and worked late when they had to keeping a tidy site I would recommend Glasspace the glass extension has added so much space and light to our home.

I have worked with Phil at Glasspace on severall projects over the last 3 years.
Phil has a great understanding of structural glass and his team are first class designers.
Our projects have been small and large glass extensions and our last job in Camden had four sets of large sliding doors.
I will continue to work with Glasspace and recommend them it is so hard to find a reliable supplier.
