Bringing Light and Air into your Basement design

Digging a basement to increase the house space has become more and more common in London over the last five years, a lot of Londoners have taken on the view of Improve don't move and to gain that extra space you can either go up and create a loft pod or go down and create a basement, or do both.

We are going to cover today basements and all the crucial points you should be considering when building a new basement if you want to feel like it is another part of the house and not in a damp and dark cellar!

It is a great way to use the space underground but to make the effort worthwhile you need to focus on two crucial topics: Light and Ventilation.

Ventilation

There are two ways to guarantee ventilation in the basement:

  • Choosing mechanical ventilation methods from simple air extractors to Positive Input ventilation (PIV), or Heat Recovery Units (MVHR).
  • Designing the basement in a way that allows natural air circulation. This can be obtained through open light wells or openable roof lights at the two opposite sides of the house.

Light

There are certain situations where darkness would be acceptable, for example in gyms, wellness areas, cinema rooms, wine rooms, utility rooms, bathrooms, etc.

But if you are intending to use the basement as a living space or provide additional bedrooms you really want some natural light to come through.

How can you bring light into the basement? Let's have a look at some examples:

  • Internal walk-on glass - This can be achieved by installing the glass at the ground floor level where there is a source of natural light, this then shines into the sublevel basement creating a warm and inviting environment.

  • External walk-on glass - Some basements will extend through to the garden and external glass will provide direct sunlight gaining an even brighter space below.

  • External Lightwells - Digging these at the edges of the house for part of the house width or for full width, this gives a huge amount of natural light and doesn't give you that boxed in feel that some basements can.

  • In more difficult situations where the space or the budget is limited it is possible to adopt clever systems to bring light downstairs like Tubular Skylights, Mirror shafts, or Fibre optic cable systems.
