So grab your materials and get ready to build a greenhouse that’s uniquely yours!
Step 1: Building the Floor
To begin building your greenhouse, the first step is to construct the floor using pressure treated wood. This type of wood is ideal for outdoor use as it is resistant to decay and insect damage. When building the floor joists, it is important to crown them. This means that you want to find the curve in each board and place it in a way that the hump is facing up. Over time, the wood will settle into this position, ensuring a level and sturdy floor for your greenhouse. The floor can be secured using a battery-operated nailer or screws, depending on your preference and the tools you have available.
Step 2: Installing the Decking
Once the floor is in place, the next step is to install the decking. For this step, you can use high-quality synthetic materials specifically designed for outdoor use. These materials are durable, weather-resistant, and low-maintenance. Before attaching the decking, it is important to square up the frame to ensure it is level. This can be done by pulling diagonals from corner to corner and adjusting until the measurements match. Once the frame is square, the decking can be securely attached using stainless steel screws. Before attaching the decking, it is recommended to power wash the boards if they have been stored outside for an extended period of time. This will remove any dirt and grime, ensuring a clean surface for your greenhouse.
Step 3: Building the Trusses
The next step in building your greenhouse is to construct the trusses. This can be done using a jig setup, which makes the process easier and more efficient. Start by attaching two blocks to the bottom side of one corner and one block about three-quarters of the way up on the opposite side. This will serve as your jig. Then, secure the top of the truss to the bottom of the truss using elongated blocks. If you have access to a CNC machine, you can cut out these shapes using it. However, if you don’t have one, free templates are available with the plans for the truss shapes. Once the truss is assembled, flip it over and attach gussets to the back side. The gable ends of the greenhouse will have additional collar ties and a vent framing for ventilation.
Step 4: Adding Stud Walls
To create the back and front walls of your greenhouse, you will need to add stud walls. These walls provide additional support and stability to the structure. They can be constructed using pressure treated wood and should be securely attached to the frame of the greenhouse. The back wall will serve as a space for siding, while the front wall will include a doorway. The dimensions of the doorway can be customized based on your needs. To ensure the walls are properly secured, they can be toenailed at the bottom and along the top.
Step 5: Paneling with Polycarbonate
For the panels of your greenhouse, it is recommended to use lightweight and strong multi-wall polycarbonate. This material is ideal for greenhouse usage as it provides insulation and allows for adequate light transmission. The panels can be installed by attaching them to the frame of the greenhouse using appropriate fasteners. Polycarbonate panels are a popular choice for greenhouse construction due to their durability and ability to withstand various weather conditions.
Step 6: Adding Trim for Aesthetic Appeal
To enhance the aesthetic appeal of your greenhouse, consider adding trim made of Western Red Cedar. This type of wood not only provides a beautiful finish but is also naturally resistant to rot. The trim can be installed along the edges of the panels and other areas to give your greenhouse a finished look. Western Red Cedar is known for its long-lasting nature, making it an excellent choice for outdoor structures like greenhouses.
Step 7: Adding Wainscoting and a Half-Lap Door
For additional design and functionality, you can add wainscoting to the bottom of your greenhouse walls. Wainscoting not only adds a decorative touch but also provides protection to the lower portion of the walls. Additionally, constructing a half-lap door for the entrance of your greenhouse can further enhance its visual appeal. A half-lap door consists of two interlocking pieces of wood that create a sturdy and secure entrance.
Step 8: Installing No-Mortise Hinges and Vents
To ensure ease of installation and operation, consider using no-mortise hinges for your greenhouse door. These hinges do not require intricate mortise cuts and can be easily attached to the door and frame. Additionally, adding vents to your greenhouse is crucial for proper ventilation. Vents can be strategically placed to allow airflow and prevent overheating, ensuring optimal growing conditions for your plants.
Step 9: Moving the Greenhouse Outside
Once your greenhouse is built, it’s time to move it outside for use. To do this, you can utilize a buggy or a portable unit to transport the greenhouse. Make sure to secure the greenhouse properly on the buggy or portable unit to prevent any damage during transportation. Additionally, using a steel battery-operated blower can help with leveling the greenhouse on-site and ensuring it is in the correct position for use.
Conclusion
Building your own greenhouse can be a fun and rewarding experience. By following these steps and using the recommended materials, you can create a durable and functional greenhouse that can be adapted for other small buildings as well. The specific materials and techniques used by April Wilkerson in her YouTube video provide a comprehensive guide for building a DIY greenhouse. Remember to take your time, gather the necessary tools and materials, and enjoy the process of creating your own greenhouse.
