How To Maximise a 20ft Shipping Container

A 20ft shipping container is a robust, adaptable space that can serve far more than simple storage. Whether your goal is a furniture storehouse, workshop, garden room or pop-up studio, smart design and fitting can transform it into a highly functional asset. 

In this guide you’ll find ideas, tips and considerations to help you maximise the value of a 20ft container.

1. Begin with a Clear Layout Plan

Before installing anything, map out how you’ll use the space. Decide what must be accessible every day (tools, chairs, crates) and what can be tucked away. Leave a central aisle at least 900 mm to 1 m wide for movement. Mark zones: one side for shelving, one side perhaps for a workstation or storage cubes, and an area near the doors for frequently used items.

2. Use Vertical Space: Shelving, Racking & Mezzanine

You don’t want to waste height. Install strong shelving or pallet racking along both long walls. Use sturdy bins for smaller items and clear labels. If your container has enough height (often around 2.6 m interior), you can consider a mezzanine shelf for light loads if structurally safe. Ceiling hooks, rails or slatted panels help with long items, such as ladders, pipes, tools.

3. Convert into a Workspace or Workshop

A 20ft container makes an excellent workshop. Helpful features include:

• A personnel door (for easy access)
• LED lighting and multiple power outlets
• A durable workbench or tool bench
• Cable management, pegboards and tool racks
• Insulation and wall lining to manage temperature and noise
• Flooring options like rubber tiles or anti-slip vinyl
• Extraction or ventilation if you’ll generate dust, paint fumes or vapour

You might split it: half as storage for consumables, half as active workspace.

4. Garden Room, Studio or Home Office Conversion

For home-use or creative space:

• Add insulation, vapour barrier and interior lining
• Fit windows or glazed doors to bring light
• Install electric heating or climate control
• Use laminate or vinyl flooring for ease
• Plan built-in storage and foldaway furniture (desk/bed combos)
• Use neutral tones and smart lighting to keep it bright

5. Hobby Room, Gym or Creative Space

If your container is a gym, install:

• Robust flooring (rubber or matting)
• Wall mirrors and mounting space
• Racks for equipment and free weights
• Secure cabinets for valuables
• Acoustic panels for music or recording
• Safe clearance zones around equipment

For craft rooms or maker spaces, include extraction, dust control and strong fixed work zones.

6. Retail Pop-ups, Event Units or Showrooms

A 20ft container lends itself to mobile retail or event use:

• Side-opening or roll-up walls for wide access
• Serving hatches or display windows
• Track lighting, slatwalls or modular displays
• Modular counters and branding vinyl graphics
• Easy transportability so you can reposition it at events

7. Climate, Insulation & Condensation Control

Furniture, electronics or fabrics stored long term may suffer from damp or condensation. Mitigate this by:

• Installing insulation with vapour barrier
• Adding low and high vents for airflow
• Using an anti-condensation liner or roof coating
• Raising items on pallets or stands to allow breathing air underneath
• Using a dehumidifier if humidity becomes an issue

8. Security Enhancements

Protecting contents is vital:

• Welded lock box and heavy duty padlock
• Door locking bars or internal bars
• Anti-jemmy shrouds on edges
• Motion sensor or flood lighting
• Alarm or camera installation
• Keep exterior clean and discrete and avoid advertising contents

9. Power, Lighting & Connectivity

Plan your electrics carefully:

• Engage a qualified electrician for consumer unit and RCDs
• Use LED battens for bright, even lighting
• Add external security lighting near doors
• Include USB ports or 12 V outlets for devices
• Run conduit for future data or network cable
• Consider mobile data (4G/5G) where wired connections are impractical

10. Delivery, Foundation & Location

How and where you place your container matters:

• Ensure access for a lifting vehicle (HIAB or crane)
• Provide a level, firm base, such as concrete pads, slabs, or proper corner block supports
• Avoid soft or uneven soil
• Use small ramps at doors if you need to roll trolleys in
• Consider drainage under and around the container

11. Maintenance & Long-Term Function

Simple ongoing care ensures longevity:

• Check and touch up paint, especially around welds
• Lubricate door hinges, seals and locking gear
• Replace or repair seals if leaking
• Sweep out debris and clean periodically
  Keep electrics and wiring neat and labelled
• Use a scheduled checklist to inspect weekly or monthly

12. Budget Tips & Modular Thinking

To keep costs sensible:

• Consider a used 20ft container if you don’t need “as-new” condition
• Use off-the-shelf racking and modular fitments rather than bespoke systems
• Keep wiring “future-proof” but simple (add modular sockets)
• Prioritise essentials first, then scale enhancements later
• Make your interior fit-outs easily removable in case you want to sell or reuse the container
  

Frequently Asked Questions

What can I store in a 20ft container for a house move?

You can fit the contents of a two to three bedroom home, including boxes, small furniture, disassembled beds, and wardrobes, especially if you use racking, vertical storage and stackable crates.

Do I need planning permission to convert a 20ft container into a garden room or office?

It depends on local regulations, the location, and how permanent the structure will be. Always check with your local planning authority to determine whether you need permission or building standards compliance.

How do I minimise condensation inside a shipping container?

Use insulation with a vapour barrier, install vents (high and low), raise stored goods off the floor, and optionally use a dehumidifier or anti-condensation liner to reduce moisture accumulation.

What base is best for placing a 20ft container?

A rigid, level base, such as concrete pads, a slab, or properly supported blocks at the container’s corner castings, is ideal. Avoid soft ground or uneven surfaces.

Can I use a 20ft container as a workshop?

Yes. With insulation, lighting, power, ventilation and tool storage, a 20ft container offers a compact, efficient workspace for many trades or hobbies.

How secure is a 20ft container?

With high quality locks, welded lock boxes, door bars and deterrents like lighting or alarms, a 20ft container can be very secure. Its solid steel structure offers substantial resistance to break-ins.

Can windows and doors be added later?

Yes,  professional fabricators can cut and reinforce openings for personnel doors, windows or roll-up walls. Ensure structural integrity is maintained and proper flashing/sealing is used.

How can I power a container in remote locations?

You can run mains supply if available, or use generator or solar systems. Install a certified consumer unit and RCD protection for safety, and plan conduit routing for future upgrades.

If I outfit a container, can I move it later?

Yes, as long as the structure remains rigid and fittings are securely mounted or modular, a HIAB or crane can relocate the container when needed.
