Converting a Shed or Warehouse Into a Gym: What to Check Before You Commit
The Short Answer
A shed or warehouse is often the best value floor space for a gym, but check five things before you sign: slab strength, it must take a loaded rig and dropped weights, ceiling height, aim for 3m or more clear under beams for rigs and rope work, power supply, ventilation and insulation, and whether bathrooms and amenities exist or can be added. Confirm council change of use before committing, and get clear in the lease on what the landlord fixes versus what falls to you.
Sheds and industrial warehouses have become one of the most popular starting points for independent gym owners in Australia, and it is easy to see why: more floor space per dollar of rent than retail strip, higher ceilings, tougher floors, and none of the shopfront glazing and fit-out constraints that come with a retail tenancy. The trade-off is that a shed is a blank industrial shell, not a fitted-out commercial space, so more of the building work sits on you.
Why sheds and warehouses make the best value floor space
Retail and showroom space is priced for foot traffic and finished presentation, and you pay for that whether or not your gym needs it. Industrial and warehouse space is priced for storage and light manufacturing, which means lower rent per square metre in most markets, larger clear spans with fewer internal walls to work around, and often a taller roof line than a retail tenancy. For a strength gym or functional training facility, that combination, space, height, a floor built for load, is usually a better starting point than a converted retail shop, even before you factor in the rent difference.
The trade-off is that a shed is rarely fitted with the amenities, insulation and finishes a gym needs, so budget for more of the building fit-out cost to fall on you rather than the landlord.
Slab strength: check before you fall in love with the space
Concrete slabs in older or lighter-duty industrial buildings are not automatically rated for the point loads a loaded power rack, a fully stacked leg press, or repeated dropped weights create. Ask for the building's structural documentation, or get an engineer to assess the slab, before you commit to a lease, particularly if the building is older or was built for light storage rather than heavy machinery.
This is a five-minute question that can save you a very expensive retrofit: a slab that needs strengthening under a rig footprint is a real cost, and it is far cheaper to know about it during lease negotiation than after your equipment has arrived.
Ceiling height: 3m or more for rigs and rope work
Aim for a clear ceiling height of 3 metres or more under any beams, sprinklers, ductwork or lighting, not just under the highest point of the roof. Functional trainers, pull-up rigs, battle rope anchors and rope climbs all need genuine clear height, and a shed that looks tall from the doorway can have beams or services running much lower across the actual training footprint. Walk the site with a tape measure and check height at the specific spots your rig, rope anchors and any suspended equipment will sit, not just the average.
If height is tight in part of the building, plan your equipment layout so machines with lower clearance needs, leg press, rowers, bikes, sit under the lower sections, and reserve the tallest clear span for racks and functional training.
Flooring goes down before equipment in almost every shed conversion, since a bare concrete slab is rarely suitable for a strength gym floor on its own. Our gym flooring guide covers rubber flooring options like EPDM Rubber Gym Flooring that suit high-impact shed conversions.
Power supply, ventilation and insulation
Sheds are commonly wired for light industrial use, which may not match what a gym needs: enough power circuits for cardio equipment, sound systems, security systems and, if you are adding a sauna or ice bath, dedicated circuits for those too. Get an electrician to assess the existing supply against your equipment list before you commit to a fit-out budget, since upgrading from single-phase to three-phase power, if needed, is a real cost and can take time to schedule with the utility.
Ventilation and insulation matter more in a converted shed than almost anywhere else. Steel sheds heat up fast in summer and cool down fast in winter, and members training hard in an uninsulated tin box in January is a genuine retention risk. Budget for insulation, extraction fans, and where the climate demands it, evaporative cooling or air conditioning, as part of your fit-out cost rather than an afterthought.

Most sheds and warehouses were not built with member-facing bathrooms, showers or reception areas, so check what exists, what can realistically be added, and who pays for it. This is where the split between landlord's works and your works matters most: some industrial landlords will contribute a fit-out allowance or complete a base level of amenities before handover, others hand over a genuinely bare shell. Get this in writing in the lease, not as a verbal promise from the leasing agent, and see our gym lease guide for how to negotiate a landlord's works schedule.
A couple on Tasmania's north-west coast converted a 400 sqm shed into a 24/7 gym with a reformer studio and a sauna recovery zone on a $200,000 equipment budget, which shows what is achievable in an industrial shell once the slab, height, power and amenities are sorted properly. Recovery additions like a MYSA Mirage Infrared Sauna or an ice bath work well in a shed conversion because the extra floor space and higher ceilings that industrial buildings offer make room for a dedicated recovery zone that a smaller retail tenancy often cannot fit.
Council change of use for an industrial-to-gym conversion
Converting an industrial or warehouse-zoned building to a gym is one of the clearest examples of a change of use, since you are moving from a light industrial or storage use to indoor recreation. Confirm with council early, before signing, whether the site is zoned to permit a gym at all, some industrial zones restrict customer-facing uses, and what parking, acoustic and building requirements come with the change. Our council approval guide covers this process in detail, and it is worth working through before you get attached to a particular shed.
Parking is worth checking specifically in an industrial estate, since some were built with minimal visitor parking on the assumption that staff and trucks, not a stream of members arriving before and after work, would use the site. Count the genuinely usable car spaces near your unit, not just what the estate's total allocation looks like on paper, before you commit.

Is a shed or warehouse a good space for a gym?
Often, yes. Industrial space typically costs less per square metre than retail, offers larger clear spans and taller ceilings, and has a floor built for load, which suits strength and functional training gyms well. The trade-off is that more of the fit-out, amenities, insulation, finishes, usually falls to you rather than the landlord.
How do I know if a shed's slab can take gym equipment?
Ask for the building's structural documentation or have an engineer assess the slab before you sign a lease, particularly in older or light-duty industrial buildings. A slab rated for storage is not automatically rated for the point loads of a loaded rig or dropped weights.
What ceiling height do I need for a gym rig?
Aim for 3 metres or more of clear height under any beams, ductwork or sprinklers across the specific footprint where your rig, rope anchors or suspended equipment will sit, not just the tallest point of the roof.
Does a shed conversion need council approval?
Almost always, yes. Converting industrial or warehouse space to a gym is a change of use, and some industrial zones restrict customer-facing businesses altogether. Confirm zoning and approval requirements with council before you commit to a lease.
What does a shed conversion typically cost?
It follows the same broad ranges as any gym fit-out: equipment budgets from $50,000 to $200,000 depending on size and format, plus building fit-out costs, insulation, amenities, power upgrades, that can run higher in a shed than a pre-fitted retail space. Get an itemised quote once your floor plan is set.
Can I add a sauna or ice bath in a converted shed?
Sheds often suit recovery additions well, since the extra floor space and ceiling height give you room for a dedicated zone. A couple on Tasmania's north-west coast converted a 400 sqm shed into a 24/7 gym with a reformer studio and sauna recovery area on a $200,000 equipment budget.
What should I check with the landlord before signing?
Confirm in writing exactly what the landlord provides, power capacity, amenities, any fit-out allowance, versus what falls to you, since bare industrial shells vary enormously between landlords. Do this before signing, not after you have already committed to the site.
