About Coastline Sheds
Our story continued
Looking for Quality, Honesty, Reliability, Service and Competitive Pricing ?
what makes us different:
Coastline Sheds is a family owned shed manufacturer based in Armadale. Since 1996 we’ve specialised in custom designed, site engineered steel framed sheds for residential, rural and commercial customers across WA.
What makes us different
-
In house fabrication: we weld our own trusses from structural RHS or angle iron steel, not light purlin frames.
-
Site specific engineering: every shed is engineered for your site, wind rating and intended use.
-
Old school durability: we favour proven, over engineered details that minimise site delays and maximise long term performance.
-
Local, personal service: you’ll deal with the owners and a trusted local dealer network for regional installs.
Our Vision
Coastline Sheds is committed to staying the market leader in high quality and tough sheds in Perth. We custom design, engineer & fabricate your shed so it can be customised to suit your needs. Coastline Sheds will never compromise on quality and integrity.
Keys to success:
-
Commitment to a high quality product.
-
Experienced people who ensure the sheds are properly designed and fabricated.
-

this shows in:

-

-
Awards: Service Awards (2014–2025) and Excellence in Small Business, Business Armadale Association 2014.
What We Offer - how we compare
We design, engineer and fabricate every shed in‑house at our Armadale workshop. As a family‑owned business we build to last using welded A‑frame trusses and robust structural steel — not light purlin frames. That means a stronger, more stable structure from the moment the frame goes up.
Why that matters:
-
Built in our workshop: our trusses are welded and assembled under controlled conditions for consistent quality.
-
Structural materials: we use RHS or welded angle steel for trusses and columns rather than thin C‑purlin framing.
-
Faster, safer installation: once our frame is up and footings poured the shed is stable; lighter purlin systems can remain vulnerable until cladding is completed.
-
Durability over time: heavier, over‑engineered details reduce movement and maintenance, so the shed performs well for many years.
-
Local, personal service: you’ll deal with the owners and an experienced local team who understand WA conditions and practical site solutions.
A fair comparison:
We don’t claim every method is wrong — some systems suit certain budgets and quick‑fit applications. Our focus is different: we prioritise engineered, site‑specific solutions and long‑term performance over one‑size‑fits‑all kit options.
Custom fabricated in Perth using welded trusses and structural steel — built to perform, not just to look like a shed.
Company Profile
Coastline Sheds started in Armadale, Perth (WA) way back in 1996 and was founded on the principles of commitment, quality, honesty, service, and competitive pricing. We specialise in custom designing, engineering and fabricating all kinds of sheds, from farm sheds to granny flats.
Our commitment to be the market leader in supplying high quality sheds with competitive pricing drives us to provide excellent workmanship and outstanding customer service for all of our customers. That is why 80 per cent of our work is coming through word of mouth - you know that your shed will be second to none.
As owner René said: “We built the sheds for the fathers, now we are building them for their sons and soon their grandsons will follow. While the dads would just look us up knowing where we are located, we know the grandsons will try to find us on Google and Facebook. Hence we also started a Facebook page based on fun around the 'Shedoholics Anonymous'” (www.facebook.com/CoastlineSheds).
In July 2014 we were awarded a 2014 Service Award based on the reviews of our customers on womo.com.au, and have since gone on to be awarded a 2015, 2016, 2017 and 2018 Service Award as well. In November 2014 we won the Excellence in Small Business Award 2014 from the Business Armadale Association in recognition of our outstanding contribution as a small business in the Armadale community.
You have our assurance that all our trusses are engineered the old fashion way within our very own workshop. We follow and exceed the industry standards for all the sheds we construct to maintain the superiority of our manufactured sheds.
We also distribute our sheds in WA through a group of distributors in country towns and around the metro area for our growing clientele. Whether you require a small or large shed for private or commercial use, Coastline Sheds will customise the right shed for you!
