Custom-Engineered Steel Sheds, Built for Newcastle's Coast Since 1997
Metal Mates is a Maitland-based business that sells custom sheds across Newcastle, Lake Macquarie and the Hunter Region, and we've been doing it since 1997. We sell garages, workshops, farm sheds, garden sheds and industrial sheds, each one engineered for Newcastle's salt air, coastal winds and council requirements. Every project starts with a free, no-obligation quote, so you know exactly what you're getting before you commit to anything.
What We Help With
Metal Mates covers every stage of getting a custom shed built in Newcastle, not just the construction. Here's what that looks like:
- Free site assessments covering soil, slope, drainage and salt air exposure
- Custom design and engineering specific to your site and intended use
- Council approvals and compliance, including Development Applications and Complying Development Certificates
- Steel supply and fabrication, sourced through trusted Australian suppliers
- Construction using BlueScope Steel framing and COLORBOND cladding
- Warranty and aftercare covering both materials and workmanship
Whether you need one part of that process or all of it, Metal Mates manages it as a single Newcastle-based team, not a chain of subcontractors.
Built for Your Property
Every shed Metal Mates provides in Newcastle is designed around your property, not pulled off a shelf. We custom-build sheds for homeowners, tradies, farmers and developers across Newcastle and the Hunter, including:
- Garages and carports sized to suit single, double or triple bay access
- Workshops with insulation, skylights and storage built for hobby or trade use
- Garden and utility sheds for everyday tools, equipment and backyard storage
- Farm and machinery sheds built tough for rural properties and oversized access
- Industrial and commercial sheds for warehousing, fabrication or logistics work
If your Newcastle property needs a skillion roof, extra clearance or custom cladding, we'll design your shed to that exact spec rather than asking you to compromise, which is the main difference between a Metal Mates build and a standard steel shed kit.

Engineered for Local Conditions
Newcastle's coastal climate is hard on steel, so Metal Mates engineers every custom shed for the conditions it will actually face, not the conditions on a generic spec sheet. Research has documented mild steel corrosion rates of 150 to 300 microns a year in exposed zones around Newcastle Harbour and Lake Macquarie, which is exactly why we match your site's corrosivity category, C3, C4 or C5, to the right steel gauge, coating and fixings before we design a single wall. We also engineer wind loading to AS 1170.2 and the relevant National Construction Code requirements, accounting for ultimate design wind speeds of 45 to 50 metres per second typical of the NSW coast, along with your soil class, slope and drainage. For a Newcastle shed, that's the difference between a structure that looks fine on day one and one that's still standing solid in twenty years.
Trusted Suppliers, Australian-Made Steel
Metal Mates builds every custom shed from quality, Australian-made steel sourced through trusted supplier partners. We work with established shed suppliers including Absco Sheds) and Metromax, giving Newcastle customers access to:
- COLORBOND steel cladding in over 20 colours, including popular coastal shades like Monument and Woodland Grey
- BlueScope Steel framing with corrosion-resistant coatings for coastal sites
- Roller doors, sliding doors, windows and ventilation built to your spec
- Insulation, skylights and cyclone-rated framing wherever your site needs it
As a steel supplier ourselves since 1997, we know which materials actually hold up in Newcastle's conditions, and we only put the Metal Mates name on the ones that do. If you'd like to see what's available before your site visit, browsing a supplier range like Absco Sheds' garden sheds collection or Metromax's shed range gives you a feel for finishes and layouts, and we'll talk you through which options actually suit your site.
The Benefits of a Custom Shed for Your Home
A custom shed adds real, practical value to your Newcastle home, and it does more than just give you somewhere to store the mower. Here's how a custom-built Metal Mates shed pays off:
- Increases property value by adding usable space and functionality buyers actually want
- Purpose-built to fit your life, whether that's a garage, a workshop or a studio space
- Engineered for Newcastle's conditions with durable COLORBOND steel and cyclone-rated framing where needed
- Saves you time and money long-term, with decades of use and minimal maintenance
Unlike an off-the-shelf kit, every Metal Mates shed is designed around your property from the start, so you end up with a space that's genuinely yours, built for Newcastle's weather, not a generic box that happens to fit your yard.
Newcastle Areas We Serve
Metal Mates delivers custom sheds right across Newcastle, Lake Macquarie, Maitland, Port Stephens and the wider Hunter Valley, working with the City of Newcastle, Lake Macquarie City Council, Maitland City Council, Cessnock City Council and Port Stephens Council. Every area comes with its own council rules and exposure conditions, and we provide for them across suburbs including:
- Coastal suburbs such as Newcastle East, Merewether, Stockton and Bar Beach, close to Newcastle Harbour and Nobbys Head, where exposure is highest
- Inner and southern suburbs including Hamilton, Mayfield, Charlestown and Warners Bay
- Lake Macquarie towns such as Toronto, Swansea and Morisset, around the lake itself
- Hunter Valley rural areas including Maitland, Cessnock, Kurri Kurri and Singleton, along the Hunter River
Wherever you're located across the region, Metal Mates designs your shed for that specific site and its specific exposure level, not a one-size-fits-all template.

FAQs About Custom Sheds in Newcastle
How much does a custom shed cost in Newcastle?
Pricing depends on size, build quality and site complexity, so there's no single figure. As a guide, a concrete slab runs $120 to $150 per square metre and council fees typically sit between $1,000 and $2,000. A basic garage costs less than a large-span farm shed or a fully fitted workshop with electrical and insulation. Metal Mates provides a fixed, itemised quote after your free site assessment so you know your exact number.
Do I need council approval for a shed in Newcastle?
In most cases, yes. Whether your shed qualifies as Exempt Development, needs a Complying Development Certificate, or requires a full Development Application depends on its size, height, setbacks and your zoning.
What steel is best for a shed in Newcastle's coastal climate?
Newcastle's salt air causes mild steel to corrode at 150 to 300 microns a year in exposed zones, so material choice matters more here than inland. Metal Mates matches your site's corrosivity category, C3, C4 or C5, to the right steel gauge and coating, using BlueScope Steel framing and COLORBOND cladding with corrosion-resistant fixings suited to your specific exposure level.
How long does it take to build a custom shed?
Timelines depend on shed size, design complexity, council approval pathway and site conditions. A straightforward residential shed on a level, accessible site can move from site assessment to completion in a matter of weeks once approvals are granted. Larger farm sheds or commercial builds requiring a full Development Application take longer.
What size shed do I need for a garage or workshop?
It depends on what you're storing and how you'll use the space. A single-bay garage suits one vehicle with limited extra storage, while double and triple bay designs give room for vehicles plus a workbench or storage racking. Workshops benefit from extra height and clear span for equipment access. Metal Mates talks through your intended use during the free site assessment and designs the shed to that exact size and layout.
