Materials That Survive Salt Air, Sun and Forty-Degree Summers
The Algarve gives us roughly 320 days of sunshine a year. That’s not a nice-to-have; it’s the whole design brief. Here, outdoor space isn’t an afterthought tacked onto the “real” house — and often, clients don’t realise this at first. It’s an extension of it.
Terraces, pool decks and covered lounges get used just as much as any living room, and we love designing those spaces. But it also means they need to withstand a high level of use, as well as salt air, UV exposure and summers that regularly reach forty degrees.
That combination is merciless on materials. Salt corrodes metal fixings and frames. Sun bleaches and degrades synthetics. Heat can warp and crack materials - and, in the case of cheap woven “rattan-style” plastics, can genuinely melt and collapse them into a sad little heap after a couple of summers. We’ve seen it all happen. It’s not pretty, and it certainly isn’t cheap to keep replacing furniture.
Invest once, properly
This is the single biggest mistake we see: treating outdoor furniture as the budget category, then filling the gaps every year as pieces fail one by one. A season or two in, you can end up with a mismatched terrace that undermines an otherwise beautifully designed home.
Good outdoor furniture deserves the same investment as your sofa — it’s just working a much tougher shift.
Wood: go teak, and pick your finish
Teak is widely regarded as one of the best choices for outdoor furniture, and for once, the hype is deserved. You have two main options:
Untreated (weathered) teak: virtually zero maintenance. Left to the elements, it naturally silvers to a soft grey and moves with the climate over time.
Oiled teak: gives a warmer honey tone, but requires annual oiling to maintain the colour. More upkeep, but a richer finish.
Both are excellent choices. It really comes down to the look you desire and how much you enjoy an annual date with a tin of teak oil.
Rattan and woven synthetics — quality is everything
Woven furniture can absolutely work outdoors, but only from brands that have genuinely engineered it for sun and heat. This is exactly where the cheap versions fall apart, often literally. The fibres aren’t properly UV-stabilised, and extreme heat can cause them to warp, weaken or even collapse.
It’s not really wood versus synthetic; it’s good versus bad. Buy well, and quality woven furniture can hold up beautifully for years.
Outdoor rugs — yes, really, and yes, they’re wonderful
If you’re used to Northern European weather, outdoor rugs have probably never crossed your mind. With rain for much of the year, why bother? But the Algarve calendar works differently, and we are very lucky here: put a rug out in April, leave it until the end of October, and enjoy it for the entire season.
It’s one of the easiest ways to bring warmth, texture and personality to a terrace or poolside.
The best outdoor rugs today are handwoven from recycled plastic fibres, and the technology has genuinely caught up with the look and feel. You’d swear you were touching wool or a soft indoor weave, rather than something designed to survive a summer outdoors. From a good brand, the colours hold beautifully too, with very little fading.
It’s a small addition that can make an enormous difference to how an outdoor space feels.
Fabrics that work indoors and out
Outdoor fabric technology has come a long way from the stiff, plasticky materials of a decade ago. The better performance collections are now soft enough, and beautiful enough, that we use them indoors too, particularly in south-facing homes where clients are often coming in from the pool in wet swimwear with sun cream still on.
Clients increasingly require their indoor upholstery to be as practical and low-maintenance as their outdoor pieces. Modern indoor/outdoor fabrics allow us to deliver that without making a room look or feel like a hotel lobby.
Lighting — the detail people forget, and instantly regret
Outdoor lighting is where quality really shows its worth, and where corners are often cut. If you’re anywhere near the coast, salt air is unforgiving on cheap fixtures. The wrong finish can start rusting and pitting within a season, and once corrosion sets in, it spreads quickly.
It’s one of those things that can look perfectly fine in the shop and then look tragic eighteen months later.
The fix is simple: invest in marine-grade fixtures designed for coastal exposure, and pay attention to the finish, not just the design. A beautiful fitting in the wrong material is really just a short-term investment in a rust stain.
Where the lights actually go is a separate conversation, and one we have with every client. It’s why our 3D projects always include a lighting plan.
The takeaway
Living well in the Algarve means designing for how a home is actually used here — indoors and out, in full sun, near the sea. Get the material choices right — furniture, rugs, fabric, lighting — and your outdoor spaces stay as good-looking in year five as they were on day one.

Frequently asked questions
Which teak finish needs less maintenance?
Untreated, weathered teak needs virtually no maintenance. Left to the elements, it naturally silvers to a soft grey. Oiled teak gives a warmer honey tone but requires annual oiling to maintain the colour.
Can woven or rattan-style furniture be used outdoors in the Algarve?
Yes, but only from brands that have genuinely engineered it for sun and heat. Cheap versions use fibres that aren't properly UV-stabilised, and extreme heat can cause them to warp, weaken or even collapse.
Do outdoor rugs really work in the Algarve?
Yes. A rug put out in April can stay until the end of October. The best ones are handwoven from recycled plastic fibres, and from a good brand the colours hold beautifully, with very little fading.
What should I look for in outdoor lighting near the coast?
Marine-grade fixtures designed for coastal exposure. Pay attention to the finish, not just the design: the wrong finish can start rusting and pitting within a season, and once corrosion sets in, it spreads quickly.
