Sustainable building materials are created by recycling materials that have been used before. These materials are durable and strong, designed to last. Some examples of sustainable building materials are:

• Wood/timber

• Sustainable concrete

• Metals

• Mud bricks/straw bales - These aren’t recycled materials, instead they’re created sustainably to be used in construction.

When new materials are produced for a construction project, this uses energy, emitting greenhouse gases. In fact, the construction industry is responsible for over 30% of global greenhouse gas emissions!

A key way for construction companies to reduce damage to the environment is to use sustainable building materials. That’s why it’s essential that more sustainable building materials are used in construction to prevent further pollution.

As we mentioned above, sustainable construction is important to protect our planet and local environments. However, there are a range of other benefits to using sustainable construction to improve your home. These include:

• Reducing greenhouse gas emissions

• Increased worker productivity - Due to working in a better environment

• Helping to prevent climate change

• Health improvements for residents - Thanks to the use of sustainable materials

• Increased property value - Using sustainable materials will make your property more appealing to buyers

• Reduced energy bills

A great way to live more sustainably is to buy or upgrade to a Passive House. These houses are built to strict standards ensuring they’re energy efficient, built using sustainable materials and have low emissions. If you’re considering making your current home more sustainable, it’s possible to make changes to upgrade your property to a Passive House.

The cost of a Passive House will vary due to the following factors:

• New or upgrading - If you’re building a new Passive House, this will be more expensive than upgrading your current home.

• Size - Larger homes require more materials and longer labour times, this increases the amount you pay.

• Materials - The type and quality of materials will affect your sustainable home cost.

• Location - Property values and labour prices vary throughout the UK.

• Layout - If you choose a more complex layout for your new home, this will increase the price you pay.

Sustainable building cost

Bearing the above factors in mind, let's look at some average sustainable building costs. For these examples, we’ve used homes built to Passive House standards. The average cost of a Passive House is £2,150 per m2. Alternatively, if you want your home to be close to the Passive House standard, this will cost an average of £2,000 per m2.
