Cooling your home in a heatwave – Natural Cooling

By August 24, 2018October 2nd, 2019Design for the future, Design, Renovation, Knowledge & Tips

If like most (sweaty) people in London this summer, you have found yourself pondering all possible ways to make your home cooler- this blog series is for you!

In this first blog, we let you know what measures you can take to reduce heat in your home naturally, in order of expense.  In Part 2 we tell you about Air Conditioning and the process to install it.

Part 1 – Natural Cooling


  • Keep windows and curtains closed during the day and open at night when the temperature drops.
  • Place ice blocks in front of fans
  • Use linen sheets (we love Piglet who have a beautiful range of colours)
  • Sit with your feet in a bucket of cool water (not a joke – it is amazing!)

Linen bedding feels and looks lovely, and is cool in hot weather



  • Purchase a good fan (Dyson are great). In rooms with no cross breeze, place fans in a series to artificially create a flow of air in and out.
  • Update your window coverings with thick material and white backing which will reflect heat back out and provide more thermal insulation both in the summer and winter.
  • Invest in a BBQ and cook outside so that your kitchen/ interiors can remain cool.

Cook outside to keep your kitchen cool


  • You could replace your flooring or wall surfaces with tiles or polished plaster or Micro cement. This style is typically used in Mediterranean countries as the surfaces are cool to the touch and everything is very easy to clean and maintain.
  • Thick stone tiles work particularly well on floors as they stay cooler longer than slim tiles. You can add underfloor heating to make sure these areas do not feel too cold in the winter months.
  • Consider your layout- make a comfortable seating area on your lower floors where it is cooler.
  • Paint your flat roof white and use lighter coloured finishes around windows and doors to reflect heat away from your interiors.

Tiles: Beautiful and practical in hot climates


  • Replace your glazing with solar treated glass- this reduces the amount of glare and heat allowed through the glass. Originally solar treated glass would have a blue tinge however new technology doesn’t look any different to normal glass.
  • Alternatively, if you’re not allowed to change your windows, secondary glazing can offer more thermal control both in summer and winter.
  • Replace fixed roof lights to openable options in order to release heat from the top of your house. New mechanical options have rain sensors which automatically close when it rains- meaning you can leave the roof light open without having to worry about the changeable weather.
  • Add sedum to your flat roof and tall trees/ plants/ climbers around your windows doors. Plants reduce heat within cities and provide shade for you and wildlife.  Remember to water your plants thoroughly at the end of every hot day and avoid watering them during peak heat as the water will evaporate too quickly from the soil.

  • If you’re at the beginning stages of planning an extension or a new build- consider whether you can incorporate natural ventilation into your design.
