Snow Forest Mountains Mountains

  • Carefree protect - 8 x 2.5L Tins
  • Embalan Paint - 7 x Tubs
  • Embadecor Stain - 7 x Tubs

The optional treatments above ( Carefree, Embadecor and Embalan ) are the treatments we can offer as well as the recommended volumes suggested for this log cabin. You will only need to choose one option out of the three if purchasing treatment with your building.

Impregnation fluid, unlike the three options above is not a weatherproofing product, instead its a very effective protector against rot, insects, ect.. This alone will not be sufficant to seal the log cabin but can be used as a base coat.

  • No Mixed timbers known as Spruce and Pine mix
  • Slow grown Spruce
  • 10 year anti rot promise
  • Dutch Standards

FREE roof Shingles: As a standard building you can select either roofing felt or FREE shingles. We cannot guarantee which colour or shape will be sent. We will always let you know the colour and style following your order. It is rarely possible to change those offered as it is dependant on our stocks.

Free shingles for this 40mm Gunda Log Cabin are the same quality as our standard range and made by the same manufacturer. However, they are last years stock and old range colours, also some packaging may not be 'as new'.

Standard Roof Shingles: These are from our standard catalogue range and are available in various colours and styles.

We highly recommend shingles with your log cabin: The final finish is far more superior and turns a shed into a stunning log cabin. Ordinary felt will last two - three years. Shingles will last for at least 15 years and it is unlikely you will ever need to replace them.

Approximate Delivery Time: 14 - 21 Working Days

Comms and delivery were great. Easy to put together and looks fantastic. Super solid unit and even with torrential rain since building it is perfectly dry inside. The thicker logs also retain temperature well so will only need heating in cold winter months. Perfect workshop.

Cabin arrived on time. Delivery driver was brilliant - managed to navigate a very restricted space at the front of our semi-detached house. The wood was packaged very well and was easy to unpack - the pieces were easy to identify. We spent a lot of time getting the foundation and first layer of wood planks laid accurately. After that it took one day to get the rest of the walls, doors and windows in place, with one and a half people working. Then it took a further day to install the roof planks. Some of the planks were bowed but only one was problematic - the rest sorted themselves out once the weight of the remaining planks 'took hold'. We are now sealing and painting the cabin. We are fitting 40mm insulation and a layer of OSB on top of the supplied roof. Overall, our only small concern was the one plank that would not sit down straight - though now we know what we know we would have sorted the planks so as to use the most bowed lower down. Overall I'd give a 95% positive report.

We ordered the log cabin online, which said was in stock, but we got a reply a few days later saying it was out of stock. But we were promised it would arrive as soon as possible. We were very pleased with the service and it arrived within a few days of the original date. We built the shed ourselves and it was very simple to follow.

Really pleased with this cabin. Great quality timber & other materials. Easy to follow instructions. Easier to construct than I thought it would be. It took me 4 days to put together from start to finish, on my own. Also very very helpful blogs.

I’ve had the log cabin up a couple of years now. When installing it I read all the articles provided by tuin, and was confident enough I could put it together. The only problem I had was with one length which had a big twist in it; others had smaller twists or bends which could be manipulated. The team were responsive and supported me with the problematic one. Two years on and aside from a couple of parts getting mouldy which I keep having to remove and the door handle which didn’t last long, I’m very pleased with the cabin. I hope to get a friend to go with it soon from tuin. I wanted to add a picture, but don’t have the option on this review page.
