Creating your own timber frame garden shed is not just a rewarding project, but it offers a practical and aesthetic solution to your storage needs. Imagine having a beautiful, sturdy shed in your garden, designed to store your gardening tools, bicycles, or serve as a cosy retreat. In this comprehensive guide, we'll walk you through the process of building a timber frame shed, utilising materials such as log lap cladding, shiplap, roof shingles, and more.
Planning Your Timber Frame Garden Shed
Before we dive into the construction process, it's crucial to plan your project in detail. Consider the size and purpose of the shed, as well as the budget and materials.
Choosing the Right Location
Start by selecting the right spot in your garden. Ensure the ground is level and has good drainage to prevent water from pooling around the shed. It's also beneficial to place the shed in a location that receives adequate sunlight, especially if you plan to use it as a potting shed.
Determining the Shed Size and Design
Next, decide on the dimensions and style of your shed. The standard size is usually around 8x10 feet, but this can vary based on your needs. Sketch out a basic design, taking into account the door and window placements.
Gathering Your Materials

The quality of materials significantly impacts the durability and aesthetics of your shed. Here’s a list of essential materials you'll need:
-
4x2 (50x100) Tanalised Timber Framing: This forms the structure of the shed. Available here.
-
32x125 Tanalised Treated Loglap Cladding: Ideal for weatherproofing and adding a rustic look. Available here.
-
Polyester Shed Roofing Felt - Charcoal Mineral: Provides waterproofing for the roof. Available here.
-
Hardwood Faced Plywood: Used for the flooring and wall panelling. Get it here.
Constructing the Timber Frame
The timber frame is the backbone of your shed, so it's essential to construct it correctly.
Building the Base
-
Foundation: Lay down a solid foundation using concrete blocks or timber bearers. This will prevent moisture damage from the ground.
-
Flooring: Attach Hardwood Faced Plywood to the foundation. This robust flooring is perfect for handling heavy loads.
Framing the Walls
-
Timber Framing: Employ 4x2 Tanalised Timber Framing to construct the wall frames. Ensure that all corners are square for a stable structure.
-
Cladding: Attach log lap cladding to the external walls, providing protection and a classic timber look.
Roofing Your Shed
-
Installing Trusses: Use the same tanalised timber framing to construct the roof trusses. A triangular design is preferred for effective water runoff.
-
Roofing Material: Apply Polyester Shed Roofing Felt to the structure. It's cost-effective and offers great durability. Consider adding roof shingles for an extra layer of protection and style.
Adding Finishing Touches
Now that the primary structure is complete, it's time to focus on the details that make your shed functional and attractive.
Doors and Windows
Select doors and windows that fit your design. A single or double door is typically sufficient. Ensure they are well-sealed against the elements.
Interior Setup
Consider installing shelves and storage units inside for organisation. Using OSB Boards is an excellent choice for internal shelving due to their strength and cost-effectiveness.
Maintenance Tips for Longevity
Your timber frame garden shed requires ongoing maintenance to remain in top shape.
-
Regular Inspections: Check for any signs of wear or damage from the weather.
-
Painting and Sealing: Use a wood preservative or paint to protect the timber from rot and insect damage.
