How to Assemble a Stilla Willow Timber Shed


Customer Dhananjay from South Australia is a proud owner of a Stilla Willow Timber Shed.

She sent us some photos and feedback about her experience which we decided to share with you in this article. We have also outlined the assembly process as per the manual with some visual aids and photos for anyone looking to buy one themselves.

The Experience

Dhananjay rated her shed and her shopping experience with Cheap Sheds, from whom she bought it from top-class (Whoohoo!)

Here is her beautiful Timber shed in all its glory.

Timber Shed - Garden shed


Cheap Sheds deserves 7 out of 5 stars for customer service. Very helpful with all queries related to the product. Prompt response to emails & phone calls. I have not experienced this level of service for an online purchase anywhere else. The product came well packaged without any damages. Delivery was very quick and I was able to track the package at every step.

Excellent product – Stilla sheds are highly recommended. I will pick these any day over the ‘tin sheds’. This product looks good in photos and looks even better once put together. Easy to assemble and comes with a comprehensive set of instructions. 10 Year warranty!

Overall very happy & satisfied with all aspects of the purchase. And yes – glad I didn’t go with the overseas made tin boxes that are totally unsuitable for the Australian climate. Tin sheds become a furnace in summer and attract spiders and bugs all year around. Compared to the aesthetic look of the ‘western red cedar’ metal sheds look very ordinary in appearance and are prone to rust and corrosion.
