Turn Your Deck into a Greenhouse: A Guide to Sustainability

Imagine stepping outside onto your deck and being greeted by a lush, thriving garden filled with your favorite plants, fruits, and vegetables. Now picture this green paradise protected from the elements, allowing you to grow and harvest fresh produce all year round. Sounds like a dream, right? Well, it’s time to turn that dream into reality! In this blog post, we’ll walk you through the process of transforming your ordinary deck into an extraordinary greenhouse. Not only will you enjoy the benefits of sustainable living by growing your food, but you’ll also create a beautiful space that enhances the appeal of your home.

Why Build a Greenhouse on Your Deck?

Before diving into how to build your deck greenhouse, let’s first explore why this is such an amazing idea for homeowners:

  1. Space-efficient: For those who don’t have much yard space or live in urban areas, utilizing existing structures like decks can be an efficient way to maximize limited space.
  2. Accessibility: Having a greenhouse attached to your home means easy access when tending to plants or harvesting produce.
  3. Year-round gardening: With the protection provided by a greenhouse structure, you can grow and harvest crops throughout the entire year.
  4. Controlled environment: You have complete control over temperature, humidity levels and pest management within your greenhouse.

Now that we’ve covered some benefits let’s move on to planning out your deck-turned-greenhouse project.

Planning Your Greenhouse

The first step in any successful project is thorough planning; here are some essential factors to consider while designing the perfect greenhouse for your deck:

Size & Location

Start by measuring the dimensions of available space on your deck; this will determine what size of greenhouse structure you can accommodate comfortably without overcrowding or compromising structural integrity. Additionally, consider the location in terms of sunlight exposure, as well as accessibility to water and electricity sources.


Choose materials for your greenhouse based on factors such as budget, climate, and aesthetic preferences. Popular options include:

  • Glass: Provides excellent light transmission but can be more expensive and fragile.
  • Polycarbonate: A durable, lightweight plastic material that offers good insulation properties.
  • Polyethylene film: An affordable option that requires replacement every few years due to wear.

Ventilation & Temperature Control

Proper ventilation is crucial for maintaining a healthy environment within your greenhouse. Consider installing roof vents or side vents to allow for airflow during warmer months. Additionally, you may want to invest in a heating system or use passive solar heating techniques (such as thermal mass) to maintain optimal temperatures during colder seasons.


If your deck doesn’t receive enough natural sunlight throughout the day, you’ll need supplemental lighting for adequate plant growth. Research the specific requirements of the plants you plan on growing and choose appropriate grow lights accordingly.

Building Your Greenhouse

Once you’ve designed your ideal greenhouse structure and gathered all the necessary materials, it’s time to start building! Below are some general steps:

  1. Prep your deck: Clean your deck thoroughly before construction begins; remove any debris or objects that could interfere with the process.
  2. Install a foundation: Depending on the weight of your greenhouse structure and local building codes, you might need to install additional support beams or footings beneath your deck planks. Consult a professional if needed.
  3. Assemble framing: Follow manufacturer instructions (if using a pre-fabricated kit) or construct framing according to design plans if creating a custom structure.
  4. Secure structure: Ensure all components are securely fastened together – including attaching the framework directly onto the existing deck – using screws, bolts or other recommended hardware.
  5. Install covering: Attach your chosen greenhouse material (glass, polycarbonate, or film) to the framework, ensuring a tight seal to prevent drafts and heat loss.
  6. Add ventilation and temperature control systems: Install vents, fans or heaters as needed based on your design plans.

Setting Up the Interior

After constructing your greenhouse structure, it’s time to create a thriving environment for your plants:

  1. Choose shelving & planting methods: Opt for tiered shelves to maximize vertical space, or consider using raised beds if you have ample square footage on your deck. Alternatively, grow plants in containers or hanging baskets.
  2. Select appropriate soil & fertilizers: Research the specific needs of the plants you plan on growing and choose suitable soil mixes and fertilizers accordingly.
  3. Organize irrigation system: Set up a drip irrigation system or hand-watering schedule to ensure consistent moisture levels throughout the year.
  4. Monitor conditions regularly: Keep an eye on the temperature, humidity levels and overall plant health; adjust ventilation, heating and lighting as needed.

Plant Selection & Maintenance

Finally – and perhaps most importantly – choose which plants you’d like to grow in your new deck greenhouse! Consider factors such as personal preferences (e.g., favorite fruits/vegetables), climate suitability (i.e., selecting cold-hardy varieties if necessary), and space requirements when making decisions.

Once planted, maintain a regular care routine that includes watering, pruning/trimming as needed, monitoring for pests/disease issues and promptly addressing any problems that arise.

Turn Deck Into Greenhouse Conclusion

And there you have it – with some careful planning, construction know-how and ongoing maintenance efforts; you can successfully transform your deck into a flourishing greenhouse oasis! Not only will this provide you with fresh produce all year round but also serve as an inviting outdoor living space where friends and family can gather amidst nature’s bounty.
