Our Services

Custom Decking

Designed around your home, lifestyle, and space — from simple platforms to multi-level entertaining areas.
Every build is tailored, not templated.

Pergolas

Freestanding or attached pergolas designed to complement your home and create a usable outdoor space all year round.

Start-to-Finish Builds

From design and council requirements through to construction and handover — everything is handled in-house.
No handoffs. No confusion. Just one team from start to finish.

Deck Extensions & Outdoor Upgrades

Already have a deck or outdoor space that’s not working?

We upgrade, extend, and refine existing builds — improving layout, materials, and overall finish so your space actually works the way it should.

About Us

Built on Craftsmanship and Quality

Surmount Construction specialises in custom decks and pergolas built with precision, durability, and genuine attention to detail.

Every board, joint, and structural element is considered carefully — because the difference shows in the final result.

We use trusted, high-grade materials and take a no-shortcuts approach to every project — ensuring your outdoor space not only looks great but stands the test of time.

Led by founder Will O’Shannessy, you’ll deal directly with the person responsible for your build — from first consultation through to final handover.
