Mark and Sally Bailey believe that if we follow their advice, the result in our homes will be as satisfying as any wholesome dish or soothing massage, but with a far more enduring effect: we'll all have a peaceful sanctuary that relaxes and comforts us.

Just listening to these two eco-friendly goods specialists talking at their Herefordshire home about the "ingredients" they recommend is calming.

Sally advises a generous dollop of natural materials, such as wood and stone, recycled furniture and then a helping of: "Milky-soft, natural colours in your home – reminiscent of large mugs of hot chocolate – to add to the feeling of relaxation.

"If you choose to create an interior that embraces the idea of simplicity, you will infuse your home with a sense of calm without really having to think too much about it."

Meanwhile, Mark says: "Stone floors and fireplaces, bare, uncovered brickwork, old tiles, wooden floors, doors and beams are star materials – especially when set off by neutral colours. Scratches, flaky paint and raw edges are all hallmarks of authenticity and craftsmanship."

The couple, who have a shop and online company selling recycled and vintage items, have made a living and a lifestyle out of their philosophy.

And it is Sally who sums up their vision: "A simple home is about keeping things plain and useful. It's not supposed to be hard-edged, with no cats, crumbs or kids allowed. Instead, it's about comfortable, relaxed living – allowing for flexibility and endless options, giving you the chance to curate your home like a personal museum."

Follow the Bailey's recipe and create your own tranquil, stress-free home:

Opt for soft, pale colours that quietly complement each other and envelop your surroundings with a sense of calm, such as milky white, beige, creamy ivory and greys.

Choose beautiful grainy wooden floors, old, worn stone and tiles, and celebrate a home's construction by leaving floors and walls unpainted or remove layers of paint and plaster to reveal their inner beauty.

Favourite things, however insignificant, should be well made and do their job without being ostentatious.

Choose home-made over mass-made whenever possible.
