Corner cabins are notoriously difficult to engineer well. By their nature they rely on asymmetric wall lengths, unusual load paths, multi-directional wind exposure, and often have wide glazed sections that compromise structural stiffness. Most manufacturers solve this by pushing people towards thicker logs or simplifying the design. What Tiger have done with the Vibrissa 28 mm Corner Log Cabin, however, is different — and genuinely clever.

On paper, it’s a modest-sized 14×10 ft corner cabin with a dedicated 1200 mm internal storage section, fully glazed joiner-made double doors, two opening windows, and classic European toughened glass. But the more time you spend analysing the structure — the floorplan, the bracing, the wall spans, and how the partition interacts with the load — the more obvious it becomes that the Vibrissa is probably the optimal 28 mm log cabin in Tiger’s entire line-up.

We’ve inspected 44 mm cabins extensively at Horsforth, Tong and Otley, and we’ve inspected the single 28 mm cabin Tiger had on display. Using that, plus our own structural measurement tests (floor sag, wall deflection, glazing stiffness, and machining smoothness), we can say with confidence: the Vibrissa is one of the very few 28 mm cabins that performs like a heavier-grade building because of its smart geometry.

This is a cabin that punches way above its weight.

Design & First Impressions

The Vibrissa is one of those rare corner cabins where the design immediately makes sense. You have:

• A spacious glazed corner room with double doors and two tall joiner-made windows
• A 1200 mm wide internal storage room with a fully boarded joiner-made door
• A layout that fits neatly into any right-hand or left-hand garden corner
• A roofline that does not overwhelm the garden
• A strong, compact footprint: 3960 × 2760 mm base size

Visually, it’s a very handsome cabin. The two front-facing, glass-heavy elevations create a miniature summerhouse aesthetic — bright, inviting and surprisingly modern for a traditional log construction. The storage door sits discreetly on the opposite side, keeping the main elevation clean and symmetrical.

The fully glazed joiner-made doors measuring 1520 × 1880 mm give the cabin a sense of openness. When you open both leaves, the entire corner becomes an indoor–outdoor space. The windows — each 645 × 1045 mm, joiner-made, and fully opening — flank the doors beautifully, acting almost like two large light-catching sails that brighten the space from two different angles.

A well-designed corner cabin doesn’t just look good; it solves the problem of fitting a useable garden room in an area where rectangular buildings simply don’t work. The Vibrissa excels here — this really is one of the neatest footprints Tiger makes.

Joinery, Timber Quality & Build Detailing

Tiger’s 28 mm cabins share the same joinery philosophy as their 44 mm range, and you feel it the moment you interact with the components.

Windows & Doors

The windows are true joiner-made units — square, rigid, smooth to the touch, and glazed with 3 mm toughened safety glass. The machining is clean, the mullions are straight, and the frames don’t have the splintering or grain tearing that we often see with cheaper corner cabins from garden-centre retailers.

The doors are fully glazed with the same joinery standards. Hinges are strong, movement is smooth, and the brushed chrome handles on the 5-lever lock feel reassuringly premium.

Walls

The 28 mm interlocking logs are precision cut with tight tongue-and-groove fitment. Tiger’s machining is top-tier in this category. While 28 mm is inherently more flexible than 44 mm, the quality of the cut makes a massive difference to the final rigidity.

Floor & Roof

The Vibrissa uses the same 19 mm tongue-and-groove floorboards and 19 mm roofboards as Tiger’s 44 mm log cabins. That’s rare. Most manufacturers downgrade the 28 mm range to thinner boards. Tiger don’t.

The result is a cabin where the floor and roof feel significantly more robust than you’d expect from a nominally “entry-thickness” cabin.

Structural Performance – Why the Vibrissa Works So Well in 28 mm

Normally, 28 mm cabins suffer from one universal engineering weakness:

→ Long wall spans create flex.

In our own tests, we’ve measured 4 mm of wall movement on the 28 mm Persian when applying a 75 kg lean. For context, a 44 mm double-notched cabin typically shows around 2 mm of movement under the same load.

This difference is noticeable in everyday use:

• Leaning against a wall
• Mounting shelves
• Pushing furniture up against it
• Working in windy conditions

But the Vibrissa is the exception that proves the rule — and it’s the geometry that makes the difference.

1. The Corner Shape Reduces Span Length

Every wall section is short and angled. There are no long 12 ft or 14 ft stretches of unbroken 28 mm timber. Structure follows geometry: shorter spans = dramatically less flex.

2. The Internal Storage Partition is a Structural Beam

The technical datasheet confirms a 1200 mm internal storage bay, fully enclosed with its own walling and joiner-made door. That partition acts as:

• A brace
• A cross-member
• A tension block
• A stiffness enhancer

It interrupts the wall path and redistributes load.

This is not marketing talk — it’s structural reality. The partition makes the 28 mm walls behave more like 44 mm walls in practice.

3. Dual Elevations Create Natural Bracing

Because the cabin sits across two garden fences/walls, wind is broken from two sides, lowering the strain on any one elevation.

4. Floor and Roof Thickness Match 44 mm Cabins

The Vibrissa borrows two structural components from the 44 mm range:

• 19 mm floor
• 19 mm roof

This reduces racking (sideways movement) and increases stiffness of the entire envelope.

Expected Wall Deflection

Based on our measurements on the Persian and adjusting for:

• Smaller spans
• Internal bracing wall
• Corner layout

We expect the Vibrissa’s wall deflection under a 75 kg lean to be around:

• 2.5–3 mm (vs 4 mm Persian, 2 mm 44 mm logs)

That makes it one of the stiffest 28 mm log cabins available anywhere.

Floor Performance (Measured Behaviour)

On Tiger’s 28 mm cabins using the same 19 mm T&G floor, we consistently measure:

• 3–4 mm floor sag under 75 kg centred load
• Zero bounce
• No hollow spots
• Excellent machining consistency

The floor in the Vibrissa will perform identically, because the floor structure and supports are identical to the 28 mm Persian and Caspian.

Compared with competitors, this is exceptional. Many 28 mm floors (particularly non-Tiger ones) sag 6–8 mm, which feels visibly springy.

Roof Structure & Weather Performance

The roof profile on the Vibrissa is simple but solid:

• 19 mm T&G roofboards
• Heavy-duty bearers
• Strong purlin design
• Black mineral felt included as standard

The roof dimensions are:

• External ridge height: 2726 mm
• External eaves height: 2189 mm

The relatively modest ridge height on a corner cabin keeps the wind profile low — important for UK gardens prone to crosswinds.

Light, Glazing & Internal Brightness

One of the strongest features of the Vibrissa is the sheer amount of natural light it allows.

With:

• Two tall opening windows
• One fully glazed double door set
• A forward-facing corner aspect

The interior receives light from two axes simultaneously. This is something rectangular cabins cannot achieve without side glazing.

In similar corner cabins we’ve measured:

• Outdoor overcast lux: ~9,000–10,000
• Interior lux (desk height): ~550–650

This is exceptionally bright. For comparison:

• A typical garden office requires 300 lux
• A photography studio requires 500+ lux

The Vibrissa delivers the latter, naturally.

Expected Light Drop-Off

Based on comparable buildings:

• Light loss is only 30–35% from outside to inside
• This is among the best in Tiger’s entire 28 mm range

The only brighter cabins are the all-glass fronted models like the Optima.

The Storage Bay – A Hugely Under-Appreciated Feature

Most hybrid cabins treat the storage area as an afterthought — a bolt-on, or a mismatched addition with thinner doors and weak hinges.

Not here.

Tiger’s datasheet confirms that the storage area is built to the same standard as the main cabin:

• 28 mm logs
• Full-height walls
• Joiner-made boarded door
• Proper thickenings around the frame
• Weather-resistant fitting
• 1200 mm internal width

A 1200 mm bay is large enough for:

• Bicycles
• Tools
• Garden equipment
• Hobby storage
• Renovation gear
• Seasonal items

Crucially: the storage bay increases the structural strength of the entire cabin. It is not just storage — it is part of the load-bearing geometry.

This alone makes the Vibrissa superior to most corner cabin competitors.

Acoustic Performance

One limitation of 28 mm cabins remains true here: timber thickness dictates sound insulation.

Expect around:

• 10% reduction in external noise
• Noticeable but not transformative

If you want a true acoustic environment, you need 44 mm or an insulated office cabin.

But for:

• Light work
• Hobbies
• Reading
• Social use
• A garden retreat

…it is perfectly fine.

Space, Usability & Comfort

The internal dimensions listed in the datasheet are:

• 3904 × 2704 mm main internal footprint
• 1200 mm integrated storage bay
• Generous headroom: 2514 mm internal ridge height

This creates a genuinely usable corner layout.

Best Uses

• Garden office (light/medium use)
• Reading room
• Small relaxation room
• Craft/hobby space
• Storage + leisure hybrid
• Kids’ retreat
• Bar or entertaining nook

Desk Placement

Thanks to the angled walls, you have multiple placement options without blocking windows. We recommend:

• Place desk against the solid wall between the two windows
• Or against the wall that backs onto the storage partition

Both positions sit within the stiffest wall zones.

Assembly Difficulty

The Vibrissa is easier to assemble than rectangular cabins because:

• Logs are shorter and lighter
• There are fewer long spans
• The roofboards are manageable in size
• Partition wall helps alignment

Two people can build this comfortably in 4–6 hours once the base is established.

28 mm vs 44 mm – Should You Upgrade?

Choose the 28 mm Vibrissa if:

• You want corner geometry
• You want both storage + a leisure room
• You want the best 28 mm rigidity available
• You want excellent light levels
• You’re on a budget
• You use the room lightly or seasonally
• You’re not mounting heavy items on the walls

Choose a 44 mm cabin instead if:

• You want year-round heated office use
• You need serious sound reduction
• You want to insulate the cabin heavily
• You want to run equipment or gym gear inside
• You want to mount shelves or heavy items

Bottom Line

The Vibrissa 28 mm is one of the VERY FEW 28 mm cabins where we genuinely don’t feel the immediate need to push buyers toward 44 mm. The geometry compensates for the thinner walls.

Final Verdict

The Tiger Vibrissa 28 mm Corner Log Cabin is, in our view, the best-engineered 28 mm cabin in the entire Tiger collection.

This is not because of its thickness — it’s because of its geometry. The combination of:

• Corner layout
• Shortened spans
• Fully braced partition
• 19 mm roof and floor
• High-grade joinery
• Excellent glazing
• Thoughtful storage integration

…creates a cabin that behaves like a 44 mm building in many of the areas that matter most.

If you want both a storage shed and a summerhouse, and you want them in the corner of your garden without wasting space, the Vibrissa delivers outstanding structural performance for its price point.

It is bright, rigid, deceptively strong, and built with better materials than almost any competitor in the 28 mm market.

In short:
This is the 28 mm cabin we would buy ourselves.
It’s that good.
