Prefab homes · studios · decks · outdoor structures
Spring helps homeowners, builders and architects deliver smart prefab houses, backyard studios, decks and site-ready structures — with less waste, clearer pricing and better buildability from day one.
What we do
A good build is won early — in the structural logic, the material choices, the junctions, the sequencing and the details that keep site work clean. Spring brings engineering discipline to residential and outdoor construction, so your project is easier to approve, price and build.
Services
Engage Spring for a single piece of engineering or the complete design-to-documentation package. Every service is built around one goal: a structure that's simple to build and stands up for decades.
Prefab homes
Compact dwellings, granny flats, secondary dwellings and modular extensions designed around efficient fabrication and fast, low-disruption assembly on site.
Ideal for: granny flats, holiday homes, downsizer homes, knock-down rebuilds and second dwellings.

Studios & cabins
Home offices, guest studios, creative spaces and rural cabins — small footprints with big design value, engineered for simple repeatable bays and quick installation.
Ideal for: work-from-home spaces, Airbnb cabins, rural retreats and teenage retreats.
Plan a studio or cabin
Decks & outdoor
Elevated decks, wrap-around verandahs, pergolas, shade structures, stairs and outdoor rooms — designed for real site conditions, wind loads, weathering and long-term durability.
Ideal for: homeowners extending outdoor living, deck builders and landscapers needing engineering.

Engineering
Practical engineering input where it matters most — footings, posts, spans, bracing, tie-downs, drainage, soil movement and build sequencing — written for the people who build it.
Ideal for: builders, owner-builders and designers who need fast, practical structural answers.
Request engineering
Documentation
Clear drawings, schedules, cutting lists and detail packs that help trades price, order and build with fewer surprises — and help fabricators make components right first time.
Ideal for: projects heading to tender, council or private certification, or off-site manufacture.

Designed for assembly
Prefabrication works best when it's designed in from the start. We plan structures around transportable modules, repeatable bays and standard material sizes — so more work happens in controlled conditions and less is left to weather, access and guesswork.
Ways to work with us
Fixed-fee proposals after a short brief — so you know the cost of design and engineering before you commit.

Process
Clear stages, clear deliverables and one point of contact the whole way through.
We clarify the site, use, constraints, budget range and the outcome you want.
You get: a fixed-fee proposal
We map the structure, spans, materials, access and construction sequence.
You get: a structural concept
Clear documentation for pricing, approvals, fabrication and site work.
You get: drawings, calcs & schedules
We help resolve details before and during the build so the project keeps moving.
You get: answers when trades need them
Example project types
From suburban backyards to sloping coastal blocks and remote rural land — the kinds of structures we help design and engineer.
Who we work with
Planning a granny flat, studio, deck or extension? We help you understand what's buildable, get comparable quotes and avoid costly surprises.
Fast, practical engineering and documentation that fits how you actually build — with someone to call when a detail needs a quick answer.
Structural collaboration that protects design intent while resolving spans, connections and prefab opportunities early.
Why Spring
Resolve the structure before the design becomes expensive to change. Early engineering is the cheapest insurance a project can buy.
Every detail should help the project move faster on site — fewer unique parts, logical sequencing and connections that are easy to get right.
Builders, fabricators, certifiers and clients should all know exactly what is being delivered — no ambiguity, no guesswork.
Systems & materials
We're material-agnostic. We recommend the system that suits your site conditions, durability needs, bushfire or coastal exposure, and how the structure will be built and transported.
FAQ
Can't see your question? Email us — we're happy to give a quick steer before you commit to anything.
Ask a questionSpring focuses on design, engineering and documentation. We work alongside your chosen builder or fabricator — or can help connect you with trades experienced in the type of structure you're planning.
Prefab can shorten time on site and reduce waste, especially on remote, tight-access or weather-exposed sites. Whether it's cheaper depends on the project — our Feasibility Check compares the options honestly for your site.
Yes. Our Engineering Pack is prepared to support development and building approval submissions, with drawings and structural information your certifier or council will expect.
A site address, a rough description of what you want to build, any sketches, photos or existing drawings, and your timing and budget range. That's enough for us to prepare a fixed-fee proposal.
Absolutely. Much of our work suits regional and rural sites, where clear documentation and prefab-ready design make the biggest difference to cost and time.
After a short brief we provide a fixed-fee proposal for the agreed scope, so you know the design and engineering cost up front — no open-ended hourly billing.
