Wooden decking has long been a trusted option for patios, terraces, and garden spaces — but in recent years, homeowners have begun to truly appreciate the long-term value and aesthetic benefits of exterior wood flooring. Whether you are building a new deck or upgrading an existing one, choosing the right wood species is key to achieving the durability, appearance, and performance you expect.
With so many options available on the market, it can feel overwhelming to decide what works best for your outdoor space. That’s why we’ve put together this list of top-recommended wood species that decking specialists and designers are relying on in 2025. From timeless favourites like teak to emerging stars like Ipe and Iroko, these materials combine natural beauty with proven resilience. Let’s take a closer look at what’s trending and why it matters.
Teak: The Classic Choice for Wooden Decking
Teak has long been considered the gold standard for outdoor wood flooring — and for good reason. This dense, tropical hardwood has a natural resistance to moisture, decay, and pests, making it one of the most durable options for exterior environments. That’s why it’s so often used in roofed terraces, luxury decks, and even boat construction.
Aside from its impressive performance outdoors, teak also boasts timeless visual appeal. Its rich golden-brown hue weathers beautifully over time, developing a soft silver-grey patina if left untreated. While teak is a premium product with a higher price tag, its low-maintenance nature and long lifespan more than justify the investment.
If you are looking for a decking material that will last for decades while maintaining its good looks, teak is a reliable and elegant choice. And if you are after a more modern or affordable look, don’t worry — there are excellent alternatives covered below that offer durability with a different visual twist.
Ipe: The Resilient Hardwood from South America
Ipe (pronounced “ee-pay”) has quickly become one of the most sought-after hardwoods for exterior wood flooring. Sourced from South American countries like Brazil, Peru, and Bolivia, Ipe is prized for its incredible density, durability, and rich natural beauty. Its olive-brown tones offer a striking visual appeal that stands out in any garden or patio design.
What sets Ipe apart is its extreme resistance to moisture, rot, termites, and even fungal growth — making it ideal for areas exposed to intense sunlight and heavy rainfall. It’s often called “ironwood” for good reason: it’s so dense that it sinks in water and wears exceptionally well, even in high-traffic outdoor spaces.
Over time, Ipe’s colour will naturally darken or fade to a soft grey if not oiled regularly. But for many homeowners, this ageing process only adds character. If you’re looking for an ultra-durable hardwood that can handle the harshest outdoor conditions while delivering luxury appeal, Ipe is a strong contender.
Iroko: The Character Wood from Africa
If you are seeking a wood that combines natural charm with reliable performance, Iroko is a fantastic option. Native to Africa, Iroko is a durable hardwood known for its distinct, uneven grain and coarse texture. These unique features give it a rustic, organic appearance that stands out from more uniform wood types.
One of Irokos most attractive qualities is the way it improves with age. As the wood weathers, its golden tones deepen into a richer, warmer hue, making your decking more beautiful year after year. It’s a wood full of character, making it ideal for those who want something a little different from the usual clean-cut look.
In terms of durability, Iroko performs very well outdoors. It is naturally resistant to moisture and less prone to warping or rotting, even in damp or coastal conditions. This makes it a dependable choice for homeowners who want a unique yet hard-wearing material for their outdoor flooring.
Balau: Strength and Stability with a Silvery Patina
Balau is another top contender when it comes to exterior wood flooring, valued for its remarkable stability and strength. Often used in heavy-duty construction, this tropical hardwood is dense, durable, and resistant to everyday wear and tear — making it ideal for decking in gardens, terraces, and poolside areas.
One of the features that makes Balau so popular is its graceful ageing process. Over time, its natural golden-brown tones fade into an elegant silver-grey patina that blends beautifully with outdoor surroundings. For homeowners who prefer a timeless, weathered look without sacrificing performance, Balau is a reliable option.
In addition to its visual appeal, Balau boasts excellent resistance to moisture, fungi, and insect attacks. Its low-maintenance requirements make it particularly attractive for those who want long-lasting beauty without constant upkeep. With the right installation and occasional care, a Balau deck can serve your space for decades.
Frequently Asked Questions
