Sustainable interior design is not a single finish or a shopping list of natural materials. It is a series of project decisions about what to keep, what to repair, what to buy, how long it may last, and what happens when it needs maintenance or replacement.
Begin with what is already in the space
Before replacing furniture or finishes, assess what can be repaired, refinished, reused, or adapted. Keeping a well-made item can reduce new purchases and preserve a useful part of the space. Record its dimensions and condition, then include it in the design brief so the new plan works around it.
Choose materials for their full service life
Compare more than the initial appearance. Ask how a product is installed, cleaned, repaired, and replaced. Consider expected wear, maintenance access, spare parts, and whether the surface suits the way the room is used. A locally available option may simplify transport or future replacement, but it still needs to meet the project's performance and quality requirements.
Ask suppliers clear questions
- What is the product made from, and where is it produced?
- How should it be installed, cleaned, and maintained?
- Can damaged sections be repaired without replacing the whole item?
- Are technical information and care instructions available?
- What happens to offcuts, packaging, or the removed material?
Reduce waste through planning
Accurate measurements, coordinated drawings, and confirmed selections can help reduce unnecessary ordering and rework. Discuss whether existing materials can be salvaged or donated, and plan how offcuts and removed items will be handled. The University of Nairobi repository includes research on waste-minimisation strategies for sustainable interior design.
Connect the brief to local expertise
Local makers and suppliers can bring useful knowledge about availability, fabrication, finishing, and maintenance. Ask for samples and product details early enough to compare alternatives. IDAK's supplier directory and professional standards resources can help readers explore the wider design ecosystem.
A sustainable brief is specific: it identifies what should be retained, which performance matters, what information is needed from suppliers, and how the finished interior will be maintained.
