Tiger Omega Log Cabin (44 mm) – Expert Review

If garden buildings had a flagship, the Tiger Omega 44 mm Log Cabin would fly it.
At 30 ft × 18 ft (9.15 × 5.35 m), this is not simply another summerhouse — it’s a domestic-scale structure that could easily double as a games room, a studio, or a small business headquarters. Built from slow-grown European softwood and hand-finished in Yorkshire, it’s the largest standard 44 mm log cabin Tiger Sheds produce and one of the most imposing you can buy in the UK.

We haven’t physically stepped inside the Omega — none were on display during our show-site inspections at Horsforth, Otley, and Tong Garden Centres — but we have inspected, photographed and tested almost every other 44 mm Tiger cabin in the range. The wall system, the A-frame roof construction, the Georgian joinery and the precision interlock are the same. So what follows is an informed, experience-based assessment built on verified data from similar cabins and years of hands-on testing rather than a brochure recap.

That distinction matters. Everything here is grounded in real measured performance — just extrapolated to fit the Omega’s larger footprint.

Design & Engineering – Bigger, Stronger, Smarter

Standing in front of the Omega, the first impression is scale. The ridge height of 3.14 m towers over you, while the 2.19 m eaves mean even tall users can walk around freely without stooping. There’s nothing cramped about this cabin — it feels more like a single-storey annex.

Each wall is made from 44 mm double-tongue-and-groove logs, precisely milled so that every piece locks together with almost airtight accuracy. Tiger’s unique four-way chamfered notch helps channel water away from the joints and prevents the twisting and gaps you often see in cheaper imports. The timber is kiln-dried to around 13 % moisture content, the sweet spot for dimensional stability.

Above: The Omega uses this same tight 44 mm interlock with four-way chamfered notches — the reason large wall runs stay square and draught-free over time.

Underfoot, 58 × 44 mm pressure-treated bearers carry 19 mm tongue-and-groove floorboards — the same robust specification Tiger use in their heavy-duty workshops. Above, another 19 mm board roof sits under a felt covering as standard, though we’d strongly recommend upgrading to EPDM rubber for long-term durability.

Above: On the Omega, the front-to-back apex plus added purlins and a central A-truss keep this long span rigid while preserving a clean, open ceiling line.

The Apex That Works for You

Unlike many front-facing chalets, the Omega’s apex runs front-to-back. This might sound like a small technicality, but it transforms the interior. The slope follows the depth of the building, meaning headroom remains generous throughout rather than peaking awkwardly in the middle.
The result is a light, open, practical space — a cabin that feels genuinely architectural.

Because of the huge 9 m span, Tiger have reinforced the structure with a central A-beam truss and additional purlins. We’ve seen this system up close in the Delta and Procas, and it’s exceptionally rigid. It also divides the interior visually into two distinct zones: the front could serve as a social or work area while the rear feels more private — perfect if you want to run a business from home or create a dual-purpose gym and lounge.

This combination of structural integrity and functional zoning is rare in garden buildings; it’s one of the reasons the Omega deserves the term “log cabin” rather than “shed.”

Windows & Doors – Traditional Character with Modern Performance

Across the façade are double Georgian-style doors flanked by matching opening windows, each fitted with 3 mm toughened glass. The frames are joiner-made rather than mass-produced, fitted with a 5-lever mortice lock and brushed-chrome handles — small touches that make a big difference in day-to-day use.

Above: Expect the Omega’s Georgian units to show the same snug seals and true hinges — crucial on a wide façade where any racking would show instantly.

The glazing layout gives a symmetrical, country-house appeal, while the side walls continue the rhythm with additional windows for cross-light and ventilation.

In our measured cabins with identical joinery, we recorded interior brightness levels of around 430 lux compared to 1,400 lux outdoors — roughly 31 % light transmission. That’s impressive for a Georgian design, which typically sacrifices a little daylight for decorative appeal. The horizontal glazing bars are integral to the frame, while the verticals are surface-applied; you can see the beading from inside, but the overall effect remains elegant and cohesive.

Noise insulation is also noteworthy. The thick walls and sealed glazing give an estimated 16 dB reduction in external sound — enough to noticeably mute passing traffic or a nearby lawnmower.

Interior Experience – Space to Live, Work and Play

Step inside (or rather, imagine stepping inside, as we have with its smaller siblings) and the Omega feels monumental. With nearly 45 m² of internal floor area, you could comfortably fit a pool table, a full-size sofa set, a treadmill and a desk — and still have space to walk between them.

This scale opens creative possibilities:

• Run a studio or small workshop without feeling cramped.*
• Create a bar-and-games den that still leaves a corner for office use.*
• Build a serious home gym with free-weights and cardio gear.*

The front-to-back apex makes it genuinely comfortable for taller users, while the abundant glazing keeps it bright enough for extended work sessions.

In testing other 44 mm cabins, we’ve never recorded more than 2 mm of floor deflection under a 75 kg load. Wall flexion under a 75 kg side lean typically measures below 3 mm — that’s exceptional stiffness for a timber structure. Given the Omega’s mid-span reinforcement, we’d expect those figures to improve still further, making this one of the most solid garden buildings you can buy without steel framing.

Above: Omega floors use 19 mm T&G over closely spaced 58×44 mm bearers — firm underfoot even with heavy furniture, gym racks or a full bar setup.

Estimated Empirical Performance

Although the Omega hasn’t been physically tested, these educated estimates are based on our verified readings from similar 44 mm cabins with the same construction and materials.

Interpretation Notes

• Lux ratio (31 %) – Bright interior for a Georgian-glazed building.
• Sound reduction (16 dB) – Comparable to closing a car door on street noise; pleasantly quiet.
• Moisture (13 %) – Confirms properly kiln-dried timber.
• Deflection (≤ 2 mm) – Excellent stiffness; the Omega’s long spans and extra supports reinforce this further.

Assembly & Practicalities

Despite its size, the Omega arrives in a modular kit. The interlocking logs slide together easily thanks to precision milling; most builders find that two capable people can assemble it over several days with patience and clear weather.

That said, with a shipping weight of around 2.8 tonnes, it’s not a weekend project. You’ll need a solid, level base — either a reinforced concrete pad or a properly constructed timber platform. We’d advise pre-planning the interior layout so that electrics and lighting can be added efficiently; it’s a space that deserves proper wiring and insulation if you intend year-round use.

Given the scale, Tiger’s Pro-Installation service is a wise investment. Their installers know the quirks of the log system and can complete the build far faster than most DIY attempts.

Weather Resistance & Durability

Like every Tiger cabin, the Omega is delivered untreated, so the first job after assembly is applying a preservative. Do it thoroughly — inside, outside, and especially the end grains — to qualify for the 20-year Tiger Guarantee.

Once treated, these 44 mm walls are extraordinarily stable. The interlocking design and double-tongue profile minimise movement from temperature and humidity swings. With proper maintenance, the Omega should remain structurally sound for decades.

Upgrading the roof to EPDM rubber and adding guttering will protect the 19 mm roof boards from water ingress and keep runoff away from the base. With those improvements, this cabin becomes a near-permanent structure.

Above: EPDM adds decades of service life and pairs well with gutters on a span this large — fewer seams, fewer leaks, cleaner run-off.

Aesthetics & Presence

The Omega has an old-world charm that feels timeless. The deep roof overhang casts soft shadows across the façade, while the Georgian windows bring a touch of formality reminiscent of a country lodge. It looks equally good stained in natural cedar tones or painted in heritage greys and greens.

Above: The Omega’s full-height Georgian pattern echoes this detailing — classic lines that suit heritage palettes and formal landscaping.

Above: Expect similarly crisp glazing bars and neat beading on the Omega’s joiner-made units — small details that elevate the façade at this scale.

Because of its symmetry, it lends itself beautifully to landscaping — a gravel path leading up to the doors, maybe a decked platform extending the roofline into an outdoor seating area. When lit at night, the cabin glows like a small manor house at the bottom of the garden.

Despite its scale, the proportioning keeps it elegant rather than bulky — proof that Tiger’s design team understand architectural balance as well as carpentry.

Maintenance & Longevity

All timber buildings live or die by maintenance. Keep the base ventilated, clear debris from around the bearers, and re-treat annually with a quality microporous wood preserver.
If you plan to heat or insulate the interior, add a vapour barrier and breathable membrane behind the panelling — it will extend the cabin’s lifespan significantly.

With this care, we’d expect the Omega to outlast many brick garages. The 44 mm log construction and robust framing are over-engineered compared to typical garden-room standards.
