When designing an extension, it's important to consider the practicalities of both form and function. One important consideration is the use of external glass walls, particularly on the first floor. While the abundance of glass creates a seamless connection to the outdoors and provides natural light, it can also lead to thermal gains and privacy concerns.

One solution to these issues is the use of reflective film on the external glass wall. This film helps isolate the interior from thermal gains, which is particularly important, as its orientation can lead to intense sunlight. In addition, the reflective film provided added privacy, especially in this area which is a bathroom that require a higher level of seclusion.

In this particular project, we specified a highly thermal efficient glass with a blue tint and further iconographic shape to create a feature out of it. The tint helps to reduce the amount of solar radiation and heat that enters the space, while the thermal efficiency helps to keep the interior cool and comfortable. In addition, we compromised on the shape by sloping the glass roof, creating a particular feature to this project, with an extruding glass wedge like structure. The reflective film further enhances the thermal performance of the glass, making it an effective solution for this project.

The use of vast amounts of glass in our design creates a seamless transition between the interior and exterior, allowing for a continuous connection to the garden. The external glass wall provides panoramic views of the garden, making the space feel more expansive, lighter and inviting. The reflective film ensures that this connection to the outdoors can be enjoyed without compromising privacy or thermal comfort.

In conclusion, the use of reflective film on an external glass wall has numerous benefits, including thermal isolation and added privacy. This, combined with the use of highly thermal efficient glass, can provide a comfortable and inviting space that seamlessly connects to the outdoors. By using a blue tint, we were able to create a feature out of the glass, adding a unique touch to the design. Overall, this project demonstrates the importance of considering practical solutions when designing an extension, without sacrificing aesthetics and functionality.
