I'm John Coupe, and I repair, refurbish and build timber sheds and garden buildings around Tunbridge Wells and across nearby parts of West Kent and East Sussex.
I work with my son Simon, combining an engineering approach with practical workshop and site experience. Whether your shed has a leaking roof, a rotten floor or simply no longer meets your needs, we can help you decide what to do next.
Leaking roof, rotten floor, failed cladding or doors and windows no longer working properly? We repair individual faults and carry out coordinated refurbishments where several parts of a building have deteriorated.
That may include roof repairs and EPDM reroofing; replacement floors, joists and bearers; structural and cladding repairs; or purpose-made doors and windows. We also look for the cause of the problem so the repair has a worthwhile long-term future.

We undertake specialist repairs to lower walls, logs, corners, floors, doors, windows and distinctive roof finishes.
We design and build bespoke sheds and garden buildings around your space, ground conditions and intended use—not a standard factory size.

I enjoy the detective work involved in repairing sheds. A tired-looking building may still have a sound structure, while a relatively tidy shed can be hiding problems beneath the floor or behind the cladding.
We look at the condition of the main structure, why it has deteriorated, how you want to use it and what will provide sensible long-term value.
Sometimes a focused repair is enough. Sometimes several related problems make a substantial refurbishment worthwhile. Occasionally replacement is the more honest and economical recommendation.
We do not assume that every old shed should be saved or that every damaged building should be replaced. The aim is to retain what is sound, correct the cause of the problem and recommend work that gives the building a worthwhile future.
Secrets of Shed Building is run by me, John Coupe, with my son Simon.
My background is in civil and structural engineering. I started the Secrets of Shed Building website in 2008 and later co-authored The Haynes Shed Manual, published in 2018.
Simon plays an important role in workshop preparation and work on site. Because we are a small business, you deal directly with the people assessing, planning and carrying out your project.
More about John, Simon and Secrets of Shed Building
We normally work within approximately 15-20 miles of Tunbridge Wells, covering nearby parts of West Kent, East Sussex and South London.
This includes Tunbridge Wells, Tonbridge, Sevenoaks, Wadhurst, Crowborough, Hawkhurst, Cranbrook and we sometimes even come up to Orpington.
We occasionally travel further for larger or particularly specialist projects.
You do not need to diagnose the problem yourself.
Send us your project postcode, approximate dimensions, a short description and a few photographs. We will review the information and let you know the most useful next step.
The website also contains practical information for people building or maintaining their own sheds, together with a developing range of shed hardware and products.
