Log Cabins

18x11 PremiumPlus Insulated Modetro Log Cabin (62mm)

For more unique features, take a look at our specifications tab.

The 5.5m x 3.5m (13' x 11' 6" approx) Premiumplus (62mm thick) Modetro Log Cabin with Double-glazing.

Our unique Warmalog® cabins have a specification far better than some competitors. This Insulated Log Cabin gives you all the advantages of a standard fully insulated cabin, but is far easier and quicker to construct. Our new and innovative logs, which come pre-made into a 62mm sandwich of timber and polyurethane offer the equivalent U-value of a 140mm wall thickness. The Avon log cabin has a secure 4-point locking system, larger purlins for extra roof strength, wide opening, tall walkthrough height French double doors, and large windows with unique Dunster House domestic hinges and multi-point locking. Unlike some competitors, our thick insulated floor and pressure treated bearers are included in the price. All this on top of the premium features of spruce timber, toughened glass and high eaves.

Customise your DunsterHouse log cabin by adding extra doors, windows, insulation and a choice of roofing options below.

Our Modetro log cabins include many features which you'll struggle to find anywhere else! From a tall walkthrough height of 6'2" and high internal eaves to wide opening French doors. If that's not enough, we also include an industry-leading 4-point locking system and additional shootbolt locking.

Let's not forget the pressure treated floor bearers with a 10-year guarantee. Or, the thick 19mm roof and floorboards which are included as standard. Not an optional extra like some competitors. Did we mention the 4mm toughened glass yet? We don't use styrene, Perspex or weak 3mm horticultural glass.

  • 18x8
