How To Choose The Right Size For Your Custom Shed In Newcastle

Step 1: Start with Purpose

Before measuring anything, define what you’ll use the shed for. Its purpose determines its size, shape and layout.

• Storage: What needs to fit inside—tools, vehicles, machinery or household items?
• Workshop: Will there be benches, large equipment or materials that require clear space?
• Garage: Vehicle size and door clearance dictate wall height and entry width.
• Business use: Equipment or delivery access may need roller doors and internal divisions.

A clear plan early on prevents costly resizing later.

Step 2: Measure the Site Carefully

Once you know what the shed is for, measure where it will sit. Go beyond the basic footprint—look at how the structure fits within your property.

Use stakes or string to mark the area and walk around it. Note:

• Council setbacks: Many blocks require minimum distances from boundaries or fences.
• Slope and drainage: Avoid low spots that hold water.
• Access points: Make sure vehicles and tools can move freely in and out.

Accurate site planning helps your shed meet both practical and regulatory requirements. Local shed design Newcastle specialists can confirm compliance and layout options before you commit.

Step 3: Plan for Growth

Sheds often fill up faster than expected. Think about what you might need in five years, not just today.



Allow space for new tools, vehicles or storage systems. It’s usually more efficient to build slightly larger now than to extend later.

Consider:

• Extra roof height for shelving or hoists.
• Additional access doors or bays.
• Open areas for flexible use.

A forward-looking design gives you capacity to adapt without rebuilding.

Step 4: Focus on Function, Not Just Area

Square metres matter—but so does how well the space works.

• Ceiling height: More headroom means better air circulation and future storage potential.
• Door placement: Position doors to suit workflow and access rather than symmetry.
• Layout zones: Separating tools, vehicles and materials keeps work efficient.
• Light and ventilation: Use natural light where possible and include vents for airflow.

Metal Mates design every custom shed in Newcastle around usability, ensuring the layout supports how you actually work or store items—not just how it looks on paper.

Step 5: Match the Size to the Setting

A shed should suit its surroundings. On smaller blocks, choose proportions that balance open space with functionality. For rural or larger properties, consider a wider structure that accommodates multiple uses without overwhelming the landscape.

Think about how sunlight, wind direction and access paths affect your site. Positioning a shed for natural light and breeze can make it more comfortable and reduce maintenance over time.

Good design integrates the shed with its environment, both visually and practically.

Step 6: Know the Difference Between Standard and Custom

Prefabricated sheds are built to fixed sizes, which can limit what’s possible on irregular sites. Custom sheds remove those limits.

They allow you to:

• Specify exact dimensions for width, length and height.
• Position doors and windows where you need them.
• Choose roof styles and pitches that complement your property.
• Create interior layouts that fit your equipment and workflow.

Custom sizing means the space fits your needs, not the other way around.

Step 7: Design for Access and Flow

A shed that’s hard to access is frustrating from day one. Plan entry points around how you’ll use the space.

For vehicle storage, allow room to drive straight in and out without awkward turns. For workshops, keep workbenches near light and ventilation. Consider separate pedestrian doors to avoid opening large roller doors unnecessarily.

The way people and equipment move through the space should feel natural and safe.

Step 8: Balance Budget and Size

Larger sheds cost more to build, but smaller ones can become restrictive. A good design strikes the right balance between space and cost.



Be clear about your essential needs and optional extras. Sometimes a slightly taller or wider design adds significant usability for minimal extra expense.

Metal Mates work directly with clients to achieve practical layouts that fit within budget without cutting corners on usability or compliance.

Step 9: Understand Local Building Requirements

Every council sets its own rules for shed construction, including placement, maximum height and approval thresholds.

In Newcastle, smaller residential sheds might be exempt from formal approval, but anything larger or more complex will require council assessment. Engaging local professionals ensures your project meets these standards before construction begins.

Metal Mates manage this process as part of their shed design Newcastle service, ensuring the correct permits are in place and the structure complies with building codes.
