FULL BACKYARD RENOVATION 🔨

A complete transformation on this one, turning the existing backyard into a clean, low-maintenance outdoor space built for year-round use.

We removed the existing pool tiles and completely revamped the area with:

▪️ WoodEvo Home Advanced Composite Decking in Antique Silver & Sandstone
▪️ H4 LowDeck Subframe throughout
▪️ Astro Turf
▪️ New alfresco and pool side decking
▪️ Glass balustrade
▪️ Black and white castellated cladding to finish off the raised areas, steps and boundary fence.

The combination of colours we get from all materials ties the whole backyard together 👌

All materials supplied by MasterWoodTurning

Another one wrapped up 🔨👌

A complete transformation using WoodEvo Home Advanced in Antique Silver, finished off with the black vertical cladding for a sharp, modern contrast.

The wide staircase and clean picture-frame detailing really set this one off. Low maintenance, durable and built to stay looking good for years to come.

Decking: WoodEvo
Supplier: Master Woodturning

From tired to transformed 👀✨

This deck had a good run, but an old hardwood surface sitting on H3 framing straight on the ground was always living on borrowed time.

We stripped it back and rebuilt it properly 👇
🔹 WoodEvo Home Advanced decking in Sandstone
🔹 H4 LowDeck subframe for durability where it actually matters
🔹 Clean lines, longer life, zero compromise
Massive thanks to the legends at and for supplying quality materials that make jobs like this a pleasure from frame to finish.
Swipe for the before ➡️
This is what doing it once, and doing it right, looks like.

Handover Complete.

Our friends at BM Landscaping finished up the concrete around this studio yesterday.

A pressure wash clean up and this job was looking like a bought one.

So many little details go into these Composite decks to achieve the results we do. From the double Fascia's, the breakerboard setout's, the end joist half spans, alll the way to the curved tree border. There's alot of unseen efforts, that seperate the professionals from the rest.

Beyond grateful to have companies such as
And to provide us with market leading materials, advice and knowledge. It's really these relationships that you build with your suppliers that push you further.

Materials Used:

-Decking, WoodEvo HomeAdvanced in Victorian Maple

-Subframe, LowDeck H4

-Joist protection,

-Fixings,

It's the little details that set apart the professionals from the amateurs.
The difference between that 15% more expensive quote.
This specific client received 2x cheaper quotes on this job but opted to go forward with ours, based on our attention to detail and portfolio. Carefully explaining why we use the materials we do and the way we do the finishes that really put the cherry on top.

Don't tarnish your skillset with cheap materials, It will only affect the face of YOUR brand.

If you excel in your craft, don't drop your prices because of an undercut. You are WORTH your experience, knowledge, and skillset.
