Tiger Delta Log Cabin (44 mm) – Show Site Review

“The first log cabin I’ve stepped into that genuinely feels like a room.”

(Inspected first-hand at Tiger’s Horsforth & Otley show sites, September 2025)

First Impressions — A Cabin That Feels Like a Building

I still remember walking up to the Delta at the Horsforth show site. Even from a distance it looked more like a small house than a cabin — broad stance, high ridge, and a generous front overhang that gives it a real porch-like presence. As I stood beneath it, drizzle started to fall, and I found myself naturally sheltering there. It already felt used before I’d even stepped inside.

That overhang, combined with the neat joiner-made architrave around the doors and windows, gives the Delta a proper architectural finish. Paint the trims a contrasting colour and it would honestly pass for a garden studio built by a contractor, not something flat-packed and delivered.

The Tiger nameplate sits proud on the wall — a small detail, but it tells you this isn’t an anonymous import.

Doors & Windows — The Feel of a House, Not a Shed

As soon as I grabbed the handle of the double doors, I knew this was in a different class. They’re heavy — not stiff, but substantial. The 5-lever mortice lock clicks closed with the same confidence as a front door at home, and the graphite weather seals compress with that satisfying car-door feel.

Each joiner-made window opens on brass stays with barely a rattle. The toughened glass is clear and distortion-free, and because they’re at a normal domestic height — not full-pane like the studio cabins — the space instantly feels private and secure. I like that. This isn’t a “glass box”; it’s a room.

Build Quality & Materials — Why the Delta Feels So Solid

Tiger build the Delta from 44 mm interlocking logs with a double tongue-and-groove profile. You can see the precision in the corners — they meet cleanly, chamfered on all four edges so water runs off and wind can’t drive in.

Standing close, you can see each log sits absolutely flush with the next. I tried sliding a fingernail into one of the joints — nothing. That’s the kind of fit that keeps draughts out without any visible sealant.

According to Tiger’s own data sheet, you’re looking at:

• 44 mm slow-grown European softwood walls
• 19 mm T&G roof & floor boards
• 58 × 44 mm tanalised bearers
• 3 mm toughened glazing
• 5-lever mortice lock with chrome hardware
• Backed by the Tiger 20-Year Guarantee

Everything about it is over-engineered in the right way. Even the floor bearers are tanalised, so the cabin never sits in damp.

Roof Design — Overbuilt for Good Reason

The roof structure uses solid 44 mm purlins running into notched gable ends, fixed with 65 mm galvanised nails. When you look up inside, those purlins are visible — thick, straight, and beautifully machined. The apex design gives you masses of headroom; even at the sides, it never feels cramped.

I always pay attention to roof overhangs on cabins because they reveal the builder’s priorities. Cheap models often stop the roof flush with the wall to save timber; the Delta projects well beyond the façade, protecting the joinery from rain.

Tiger include heavy-duty black mineral felt as standard, but if you can, upgrade to the EPDM rubber roof. I’ve seen it on other Tigers and it’s virtually maintenance-free for decades.

Inside the Delta — Quiet, Warm and Surprisingly Refined

Stepping through those doors is a lovely moment. The outside noise fades away and you get that faint echo only dense wood gives. The air smells of fresh pine — that clean, resinous scent that makes you want to take a deep breath.

I ran my hand over the interior walls: smooth, cool, no roughness. Looking up, the 44 mm roof beams span right across; they’re the reason this structure feels so rigid. Nothing flexes. Nothing creaks.

Walking around, I tried listening for any floor noise. Nothing again. The 19 mm boards are screwed down onto those close-spaced bearers, so you get a heavy, silent floor — more like a room extension than a shed.

It’s a big space. The model I was inside — the 20 × 16 — could easily take a full gym setup, a large desk and seating area, or even a small pool table. With the ceiling height and symmetry, it feels balanced and purposeful.

I said it on the recording and I’ll repeat it here: this is the first garden building I’ve been in that genuinely feels like a proper room.

Dimensions & Model Options

Image: tiger-delta-44mm-log-cabin-gable-end-horsforth.jpeg

The Delta comes in an impressive spread of footprints, from 14 × 10 ft up to 20 × 18 ft. Internal ridge height ranges from 2.83 m to 3.24 m, so even the smallest version feels tall and open.

Smaller sizes (14 × 10, 16 × 12) make brilliant home offices or studios. Go 18 × 14 or 20 × 16 and you’re in true multi-use territory — a gym, a guest lounge, a bar. The square 20 × 18 version would even suit a snooker table with space to walk around.

The modular floor plans Tiger supply are clear and logical, showing just how much usable space you gain compared with the 28 mm models.

Assembly — Straightforward but Heavy-Duty

The Delta goes together the way a proper log cabin should: the wall logs stack and interlock layer by layer, each course locking the last. It’s simple work, but because these are full-depth 44 mm logs, they’re heavy. Two people minimum, ideally three when lifting the roof sections.

Tiger’s manual (INS37-WEB) is one of the clearest I’ve seen — it shows every fixing type and even reminds you to pre-drill screw holes to avoid splitting. Their Pro-Installation Service is worth considering for anything above 16 ft. I’ve seen the teams in action; they know every tolerance and settle the doors perfectly.

As always, start with a level, firm base. I’d use concrete or EcoBase grids at least 25 mm above ground level to prevent splash-back.

Finishing & Treatment

Every Tiger cabin leaves the mill untreated, so once it’s assembled you need to apply a good oil- or solvent-based preserver, inside and out. It’s essential for the 20-year guarantee.

Personally, I’d go for a two-tone finish: anthracite grey on the main body and Cornish Cream or Taupe on the trims. Standing in front of the Delta, you can just picture how that contrast would bring the joinery to life.

Tiger’s own TigerSkin® Wood Protector range works well, or any high-quality microporous system like Sadolin Classic.

Weather Resistance & Performance

I like to test cabins by looking for daylight through the joints. In the Delta — nothing. The interlocks are so snug that even without any sealant you can’t see a hairline. The thick logs give it real thermal mass; on a cold day it already felt warmer inside than out, and that was without any heating.

The 19 mm roof and floor, combined with those solid walls, make this an all-season cabin for everything except the coldest winter days. Add floor insulation or a small oil heater and you’re set year-round.

During my walk-through, the atmosphere stayed dry and there was zero sign of condensation around the glass — always a good indicator of ventilation balance.

Maintenance & Longevity

If you treat it properly, this is a decades-long building. The key points are simple:

1. Keep it clear of ground moisture — don’t let soil or decking touch the walls.
2. Re-treat annually — especially south- and west-facing sides.
3. Check the storm braces each spring; they should move slightly as the logs expand & contract.

Do that, and the 20-year Tiger Guarantee isn’t optimistic — it’s realistic.

Custom Options & Upgrades

Tiger’s bespoke service lets you tweak almost everything. Popular Delta upgrades include:

• EPDM rubber roof kit for 25-year durability
• Coloured shingles (red, green, black, grey)
• Double glazing upgrade for winter use
• Decking extensions on matching bearers
• Guttering kit (pre-mounted on boards)
• Internal bar modules — ideal for a garden pub setup

Add a small deck and a couple of outdoor lights under the overhang and it becomes a genuine garden room, not just a cabin.

Real-World Use — How It Feels to Live With

Standing inside, I kept thinking how easy it would be to forget you were in the garden. The acoustics are soft; conversation doesn’t echo, which is why it works so well as an office or recording space. The thick walls dull outside sound surprisingly well — I could barely hear passing traffic.

I also love how the Delta bridges two worlds: it has the craftsmanship and smell of real timber but the solidity and security of a home extension. You could put a sofa bed in here, install electrics, and have a genuine guest room.

Verdict — A Proper Garden Building in Every Sense

After inspecting dozens of log cabins over the years, the Delta still stands out for its sheer presence. It’s confident without shouting for attention — a design that feels right from every angle.

If the 19 mm TigerFlex® range is for occasional use and the 70 mm Black Tiger for all-year luxury, the Delta 44 mm sits beautifully in the middle: robust, versatile, and refined.

It’s the cabin I’d recommend to anyone who says, “I want something that feels like a real room, not a glorified shed.”
