Why Choose A Cedar Summerhouse?

Summerhouses and Garden Buildings can be constructed from a number of timbers so when purchasing a summerhouse, it’s important to consider the longevity and stability of the material used for construction. Western Red Cedar is one of the world’s most durable of timbers so is the perfect choice for your summerhouse. Although it tends to be more expensive than European Redwood or other timbers, it is far superior as it can last over double the time with no maintenance. Cedar is naturally durable and stable meaning it is less likely to split and warp.

Summerhouses have to endure the extremes of weather, from wet cold winters to the heat of midsummer. When a summerhouse is left with doors and windows closed on a hot sunny day the heat build-up inside the summerhouse can create a sauna like effect. As the moisture in all timber increases or decreases to suit the environment, it’s essential to use a timber that remains stable. If not doors, windows and cladding can move as the timber either expands, shrinks or warps.

Western Red Cedar is one of the few wood species that are naturally at home in the outdoors. Properly finished, Cedar will last for decades, even in the harshest environments. It’s natural resistance to moisture, decay and insect damage make it the ideal choice for a surface that is exposed to sun, rain, heat and cold all year.


Trada is the leading authority on timber in the UK, they provide information to enable you  to compare cedar with other timbers.

Western red cedar is a stable and durable timber that is used extensively for building. It has a natural resistance to decay and insect damage, the wood of large, fallen trees can remain sound for over 100 years. Western red cedar is native to Northern America where it is one of the most widely used building materials, typically used for cladding and roofing enduring the harshest of seasonal climates.

European Redwood is typically used because it is readily available and is relatively cheap to buy, however it is classed as only slightly durable with medium movement and can have a lot of problematic knots. European redwood is widely chemically treated to make it last longer. Western Red Cedar will last longer without the movement.

Thermawood is redwood that is heat treated to make it more durable and stable. Thermawood has a lot of knots and becomes brittle due to the heat treatment process.

Red Grandis is in comparison a relatively new timber to the UK that is fast grown on plantation in South America. Red Grandis is a cheaper alternative to other hardwoods such as Sapele or Meranti. Red Grandis is classed as only moderately durable and has medium movement.


Other Reasons To Choose Western Red Cedar For Your Summerhouse



It’s Beautiful

Aesthetically, there really is no substitute for the natural beauty of Cedar. Imbued with decidedly crisp, yet superbly rich, tonal properties, Cedar can create sublime outdoor summerhouses. You can recognize Western red cedar by its pink to reddish colour, sometimes intermixed in broad bands of amber, cream and brown. Mostly straight-grained, the grain may occasionally wander with swirls of colour, there really is nothing else that compares to this natural beauty. Cedar’s rich and variegated colouring ranges from pale saffron to a deep honeyed ochre that, over the years, gives way to an attractive patina of silvery grey.

It’s Versitile

Western red cedar is pitch and resin-free. Which means it’s ideal for accepting and holding a wide range of beautiful finishes including elegant stain or paint. Being very straight-grained, Western Red Cedar has excellent dimensional stability and endurance. This quality means that it neither warps nor twists, therefore ensuring that the finished summerhouse is able to stand the test of time. Cedar wood doesn’t shrink, swell or warp to the extent of other timbers  even under severe changes in humidity or temperature. Its large proportions of cell cavities, which are filled with air, give it high-thermal insulation.

It’s Sustainable

Independent studies prove that when it comes to environmental performance, natural wood is superior to synthetic products in every way. While other building materials generate greenhouse gasses, western red cedar actually removes greenhouse gasses from the atmosphere. And unlike brick, cement and composites, Cedar is renewable and biodegradable. Plus, Cedar is sourced from the most sustainably managed forests in the world.

At Chelsea Summerhouses we use Western Red Cedar to provide quality summerhouses knowing they are built to last in the assurance the timber we’re using is durable with very little moisture movement. Our experience and knowledge is built on decades of working within the industry of manufacturing high end summerhouses and conservatories, using designs dating back to the early 1900’s. Indeed, there are still fine examples of these structures standing that are over 100 years old. Years of research and development, trying and testing different timbers, including those mentioned above has only confirmed that Western Red Cedar is absolutely the best timber for our buildings.
