Maximising Natural Light: Architectural Strategies You Should Know

At Karenna Wilford Architects, we believe natural light is one of the most powerful elements in architectural design. It shapes our mood, transforms space, and plays a crucial role in energy efficiency. But achieving truly effective daylighting goes far beyond simply “adding more glass.”

In this post, we explore the advanced techniques and considerations that go into designing light-filled homes — even in tight, shaded or urban plots

1. Types of Light: It’s Not Just About Brightness

Architects distinguish between:

• Direct light – crisp, strong sunlight, ideal for living spaces but can create glare

• Diffuse light – soft, ambient illumination, often best for workspaces or bedrooms

• Reflected light – bounces off surfaces to fill deeper parts of the home

  
  

A well-designed scheme combines all three. For example, light bouncing off a pale wall opposite a window can brighten an entire room without direct exposure.

2. Designing for Urban or Shaded Plots

Not every site enjoys open skies. In tighter locations, we use clever strategies like:

• Clerestory windows – high-level glazing brings in light without compromising privacy

• Light wells – vertical shafts that draw light into basements or internal bathrooms

• Courtyards – create pockets of light and greenery within dense layouts

• Borrowed light – using glazed internal walls or transoms to move light between rooms

3. Energy Efficiency and Natural Light

Natural light doesn’t just look good — it also saves energy.

Maximising daylight reduces reliance on artificial lighting and, when used strategically, can help with passive solar heating, especially in winter months.

Modern glazing options also support energy performance. For example:

• Low-iron glass allows more light through

• Solar control glazing reduces overheating

• Thermal coatings improve insulation

  
  

We balance these choices to meet both sustainability goals and planning compliance.

4. Light in Planning and Building Regulations

When submitting plans for approval, we include light-related considerations in:

• Elevation drawings with sun angles

• Shadow studies for neighbouring properties

• Window placement to ensure compliance with rights to light

  
  

This attention to detail helps streamline planning permissions and avoid objections, particularly in conservation areas or infill developments.

Conclusion: Natural Light is a Design Priority, Not a Luxury

Whether you're building from scratch, extending or renovating, natural light should be a central design priority. It improves comfort, health and even property value — but it requires thoughtful planning, especially on challenging sites.

At Karenna Wilford Architects, we specialise in integrating light into every layer of the design — from the first sketch to final sign-off.
