Balancing Daylight, Privacy and Performance 

A key challenge of the project was achieving high levels of natural light without compromising privacy between neighbouring units or surrounding properties. 

The compact nature of the site, combined with close proximities and varied building forms, required careful positioning and sizing of every glazed opening. The architectural intent relied on glazing to introduce daylight deep into the homes, while overlooking had to be carefully controlled. 

At the same time, the development targeted enhanced environmental performance, exceeding standard Building Regulations through a fabric‑first approach. The glazing therefore needed to deliver strong thermal efficiency while maintaining slim sightlines and supporting the overall architectural language. 

Tailored Glazing Design to Maximise Light and Control Views 

IQ Projects developed a considered glazing strategy that responded directly to the constraints of the site and the architectural intent. 

Glazed openings were carefully proportioned and positioned to draw natural light into key living areas while maintaining privacy across the courtyard arrangement. Slim casement windows and larger glazed door systems provide controlled visual connections without creating direct overlooking. 

The glazing enhances the spatial experience of each home, allowing compact layouts to feel open and light‑filled. Floor‑to‑ceiling elements in selected areas maximise daylight penetration, reinforcing the courtyard as a central lightwell and extending the perception of internal space. 

At the same time, the consistent use of slim framed systems ensures that the glazing integrates seamlessly with the industrial material palette, maintaining a clean and unified architectural expression. 

Technical Details 

• A Sieger Lux double door to the ground floor open plan living, dining, kitchen area, measuring 2.7m tall x 1.7m wide. The door includes two decorative horizontal transom bars to create a timeless steel look finish.  

• To each side of the Sieger Lux double door are two fixed aluminium framed windows measuring 2.7m tall and 1.7m wide each with the same decorative transom design to match the door. Both windows include trickle vents which are PPC to match the frames. 

• On the returning wall of the ground floor open plan living, dining, kitchen area, overlooking the entrance pathway, is a fixed aluminium framed letterbox window measuring 0.6m tall x 1.9m wide. This window includes a trickle vent PPC to match the frame.  

• A Sieger Lux bi-folding door to the garden facing elevation of another unit’s kitchen-diner measuring 2.6m high x 2.7m wide in a three-panel configuration. The door includes two decorative horizontal transom bars to create a timeless steel look finish. 

• A Sieger Slim aluminium window arrangement to the living room of the same unit, measuring 2.3m high x 2.7m wide in total. This arrangement consisted of a series of fixed windows with two top hung windows at the head.  

• Two slim framed two panel sliding windows were installed to the mezzanine floor of both units;  

• One to a bedroom that measured 1.4m tall x 4m wide in a letter box design.  
• One to the top of a staircase that measured 1.4m tall x 1.4m wide.  

• All glazing is specified as heat‑soak tested double-glazed units with low‑E coatings and argon gas filling as standard. The Sieger Slim sliding doors at mezzanine level incorporate solar control glass due to their more exposed location. 

• All framing is manufactured from thermally broken aluminium and finished in RAL 7021 Matt.
