4. Straw Bales

Straw Bales

Straw bale construction is a technique as old as agriculture itself, yet it offers solutions for the future. Straw bales provide exceptional insulation and are a renewable resource, making them an excellent choice for eco-friendly construction. The charm of a straw bale home is not just in its environmental credentials but also in its aesthetics. The thick, textured walls have a unique beauty and offer a level of comfort and quiet that conventional materials struggle to match.

Insider Tip: Ensure the straw bales are properly sealed to prevent moisture ingress, which can lead to deterioration over time.

5. Reclaimed or Recycled Wood and Metal

Reclaimed or Recycled Wood and Metal

Reclaimed wood and metal bring history, character, and sustainability to a project. Each piece tells a story, whether it’s wood salvaged from an old barn or metal repurposed from a decommissioned ship. Not only does their use reduce the demand on forests and mines, but it also decreases waste. I’ve seen reclaimed materials transform spaces, adding warmth and texture that new materials simply cannot replicate.

Insider Tip: When sourcing reclaimed materials, look for suppliers who can provide a history of the material, adding an extra layer of narrative to your project.
