Decks, carports & retaining walls

Deck engineering

For deck builders, builders and owner builders.

Two details cause most of the trouble

The first is the connection back to the house. A deck hung off existing framing loads a wall that was never designed to carry it. The second is the balustrade, which has to resist a crowd leaning on it, not just hold itself up. We design both rather than leaving them to judgement on site.

What we do

We size footings, bearers and joists for the deck’s spans and use, design the connection to the house or make the deck freestanding, and detail stairs and balustrade fixings.

What you receive

Footing, bearer and joist design, connection details at the house, balustrade fixing details, and drawings and certification for approval.

Common questions

Frequently asked

Does a deck need an engineer?

Elevated decks, decks attached to the house and decks outside the standard span tables generally need structural design and certification for approval. Your certifier will confirm what they need.

What are the most common deck problems?

The connection back to the house, where a deck hung off existing framing loads a wall never designed to carry it, and balustrades fixed to hold themselves up but not to resist a crowd leaning on them.
