Backyard Gym — Your Personal Gym, Steps from Your Door.
A Garden Room gives you a dedicated, four-season home gym in your backyard — proper flooring, full ceiling height, a real mini-split, and no commute. Here is everything you need to know about backyard gym ideas and how a Garden Room makes them real.
The short answer
A Garden Room is a better home gym than a garage corner or spare bedroom because it gives you a dedicated floor made for impact loads, a proper ceiling height for pull-up bars and overhead lifts, and a fully insulated, climate-controlled space that is separated from your home. You get the quiet and focus of a real gym without the drive, the membership cost, or the equipment waiting game. The Garden Room 118 fits cardio, weights, yoga, and a mirror wall. The Garden Room 158 adds room for a full squat rack, barbell, bench, and a dedicated stretching zone.
Why a backyard gym works better than a gym membership
The average gym membership costs $50–$100 per month — that is $600–$1,200 a year, before you count drive time, parking, and the friction of actually going. Over five years, a mid-range membership at $70 / month adds up to $4,200 in fees alone, and you still own nothing at the end of it.
A Garden Room is a one-time investment that becomes a permanent part of your property. You stop paying monthly fees the day it goes up. Here is what a dedicated backyard gym gives you that a membership never can:
- No drive time. Walk across your yard. Your workout begins in 60 seconds, not 20 minutes.
- Always available. No peak-hour crowds, no holiday closures, no one else’s sweat on the bench.
- No waiting for equipment. Your squat rack, your barbell, your pull-up bar — ready when you are.
- Set it up exactly how you want. Rubber flooring, mirror wall, your playlist at your volume, chalk allowed.
- Works with your schedule. 5 a.m. or 11 p.m. — no staffed hours to work around.
- One-time investment, not a recurring drain. The Garden Room 118 starts at $17,990 USD; the Garden Room 158 at $19,990 USD.
The math: A $70 / month membership costs $4,200 over five years and $8,400 over ten. A Garden Room 118 at $17,990 pays for itself in gym fees avoided in roughly seven years — and is still there, still yours, on year eleven and beyond. And unlike a membership, it adds perceived value to your home.
What fits in a Garden Room gym
Both models are fully functional gyms. The right one depends on the equipment you want and how much floor space each piece needs. Here is a side-by-side look at what a well-planned setup looks like in each model:
Garden Room 118
118 sq ft — ideal for focused training setups
- One cardio machine (treadmill, bike, or rower)
- Dumbbell rack + adjustable bench
- Wall-mounted pull-up bar
- Yoga mat and stretching floor space
- Full-length wall mirror
- Small equipment shelf or hooks
Best for: cardio + weights, yoga + mobility, or focused single-discipline training.
Garden Room 158
158 sq ft — room for serious strength and cardio
- Full squat rack with barbell and weight plates
- Flat / incline bench
- Dumbbell rack or kettlebell wall
- One cardio machine (treadmill, bike, or rower)
- Dedicated stretching zone with mat space
- Mirror wall on one side
- Equipment storage cabinet or built-in shelf
Best for: powerlifting, CrossFit-style setups, or multi-person home gyms.

Floor and equipment considerations
Getting the details right makes the difference between a gym you love using and one you avoid. Here is what to think through before your first workout:
Rubber flooring over the SIP floor
The Garden Room’s Boxway Aluminum SIP floor panel is strong enough to handle the load, but rubber flooring is recommended for any gym setup. Interlocking 3/4 inch rubber tiles protect the SIP surface, absorb drop impact, reduce noise transmission, and give you the right grip underfoot for deadlifts, squats, and jumping movements. A full floor covering of 3/4 inch horse-stall mats or premium rubber tiles runs about $2–$5 per square foot and is the single best gym-specific upgrade you can make.
Ceiling height for a pull-up bar
The Garden Room has sufficient ceiling height for a wall-mounted or free-standing pull-up bar — a detail that immediately rules out most garage corners and finished basements with low ductwork. Whether you bolt a bar into the wall header or mount a freestanding power rack, overhead movements are comfortable and safe. Ceiling-mounted pull-up stations are also an option for installations that want to keep the walls clear.
Ventilation with a mini-split
A gym produces more body heat per square foot than almost any other use. The Garden Room comes equipped for a mini-split HVAC unit — an efficient single-zone heating and cooling system that keeps the room at your target temperature regardless of outside conditions. In summer, it prevents the dangerous heat buildup you get in an unventilated garage gym. In winter, it makes a cold-morning workout genuinely comfortable. The mini-split also manages humidity, which protects metal equipment and keeps the space fresh.
Mirror wall
A full-length mirror on one wall is worth adding during setup, not as an afterthought. It gives you real-time form feedback during lifts, makes the space feel larger, and reflects natural light if you have a window on the opposite wall. Standard 3/4 inch tempered gym mirrors can be adhesive-mounted directly to the SIP wall panels. Most owners cover a 6-foot by 4-foot section at minimum; full-wall coverage is achievable in both models.
Storage for equipment
A well-organized gym is a gym you actually use. Plan storage before you move equipment in: wall-mounted dumbbell brackets, vertical barbell storage, a corner plate tree, and hooks for bands, ropes, and jump ropes all go up before the rubber floor. The Garden Room 158 has enough square footage to include a dedicated storage cabinet or wall shelf system without eating into workout area.
Year-round use — every season, every climate
The most common reason people abandon a garage gym or a spare-room setup is temperature. In February, it is too cold to grip a barbell. In July, the garage is a sauna. Inconsistent conditions break training habits. A Garden Room solves this by design:
SIP insulation — all four seasons
The Boxway Aluminum SIP panel system delivers the same thermal performance in January as it does in August. No fibreglass batts to compress over time. No thermal bridging through metal studs.
Warm in winter cold
The mini-split heats the space efficiently in sub-zero temperatures. Come out to a 65°F gym even when the backyard is covered in snow. The SIP shell retains heat between sessions so warm-up time is minimal.
Cool in summer heat
The same mini-split unit cools in summer. Unlike a garage with a single box fan, the Garden Room reaches and holds your target temperature in minutes. Training in heat stress is optional, not mandatory.
Quiet from the household
The SIP envelope and the detached structure work together to keep your training noise out of the house and the house’s noise out of your workout. Lift heavy, drop bumpers, play music loud — the household sleeps on.
Put it together and you get a gym that has no off-season. No month where it is too hot or too cold to train. No Saturday morning where the kids’ soccer game on TV bleeds into your focus set. A Garden Room backyard gym is the closest thing to owning your own commercial gym at a fraction of the cost.
