Description
A beautiful, sizable log cabin made from 28mm interlocking, tongue and groove timber logs. With this upgraded model you gain the added benefit of double glazing, allowing you potentially all-year-round use.
The main access is through a double door which is flanked on either side by large opening windows. The roof of the Haven log cabin extends out beyond the front of the building as a shelter or sun shade.
Unlike full panel sectional buildings (like sheds), log cabins are built from the ground up with each log placed strengthening the building. As the weight of the building is focused at the foot of the walls, do make sure your base is suitably strong.
In common with this type of building, the logs are supplied untreated and One Garden recommends applying a coat of wood treatment to the building as soon as possible after installation.
Double glazed glass is supplied for the windows and green mineral felt is supplied to cover the roof.
Fixtures, fittings (including a key operated lock for the door) along with full instructions are provided as standard.

Delivery
Overview
The Mercia Haven Double-Glazed 28mm Log Cabin 4.0 x 4.0m is delivered from central UK stocks held at our manufacturer. The manufacturer's own experienced personnel undertake delivery with careful handling to ensure the goods arrive in a perfect condition.
Vehicle
This manufacturer operates mostly 3.5 ton small flat-bed trucks. These will reach most locations an average car can. On occasion, a larger 7.5 ton lorry may be necessary.
Access
Unloading will take place at the kerb-side or onto your adjacent driveway. Vehicles will not leave the public highway. A driver may be willing to carry the goods into your garden at their own discretion. Goods cannot be carried through your home, therefore if necessary please arrange some extra help privately.
Free Delivery
This manufacturer offers free delivery* within central, mainland England only. The above postcode checker will confirm this for you.
Delivery Period
Delivery will typically be made within the period quoted on this product. The manufacturer will notify you in advance by either telephone, text or email to confirm the date of delivery. On the morning of delivery, an email or text will be sent by the manufacturer to advise you of an estimated '2 hour delivery time slot'. Where possible, the driver may also call to update you on their progress.
Pick A Day Delivery
Should your location qualify, during the checkout process you will be offered a real time calendar which will allow you to select a preferred delivery date. The manufacturer will endeavour to deliver on the date you have chosen. You will be promptly notified in the rare event that an alternative date is necessary for logistical reasons.
Orders with Optional Installation
The delivery of your goods will happen independently (as if for a self-assembly order) and prior to installation. Typically, the manufacturer's installation team will be scheduled to visit your address 2-3 days after delivery. You will be advised of the installation date by telephone. Note: Due to additional labour scheduling, an installation service option may add approximately 3 weeks to the overall delivery period.

Attributes

10 Year Anti-Rot Warranty
An assurance from the manufacturer that their timber product, if maintained according to their re-treatment policy, will resist rot within a 10 year period.

FSC Certified
The Forest Stewardship Council promote responsible forest management. The manufacturer will have used FSC certified timber from managed resources.

Professional Installation (optional)
Some products have installation available as an option. For an extra charge, professionals will come to your property to install the product. An appropriately sized, firm and level base will need to be available for them to install.

Untreated
Commonly relating to timber, this reflects that no form of preservative treatment has occurred. To maintain the timber's lifespan a preservative should be applied once exposed to the elements.

Interlocking Log
Forming the basis of log cabin construction, interlocking logs are notched rails which 'lock' together where they cross. Each has a tongue and groove (formats do vary) to create a near-continuous joint.

Mineralized Roofing Felt
A garden building roofing felt in its commonest form. Coated externally with small stone flakes or grit to deter the effects of weathering.

Double Glazed
Two sheets of glass with a sealed air pocket in between. Offers superior insulation and heat retention while also being extremely tough to break.

Key Lock
A common security device enabling a door to be locked, which can only then be opened with the key provided. The image details a Press Lock, however the design and finish can vary by product.
