Attached Greenhouses: Costs, Ideas & DIY Tips

The allure of fresh produce year-round, coupled with the satisfaction of nurturing plant life, makes the idea of greenhouses attached to houses increasingly appealing; imagine stepping directly from your kitchen into a sun-drenched space filled with herbs and vegetables. Companies like *HOK*, renowned for sustainable designs, often incorporate integrated agricultural spaces into residential projects, demonstrating the growing trend of blending living spaces with food production. The *National Greenhouse Manufacturers Association (NGMA)* provides valuable standards and resources for ensuring the structural integrity and safety of these attached structures. Moreover, understanding the principles outlined in *Eliot Coleman’s* “The Winter Harvest Handbook” can be incredibly beneficial for maximizing yields in a home greenhouse environment. Finally, location is key; the microclimate around *Boulder, Colorado*, known for its intense sun and variable temperatures, presents unique challenges and opportunities that highlight the importance of careful planning when building greenhouses attached to houses.

Designing Your Dream Attached Greenhouse: A Step-by-Step Guide

Embarking on the journey of adding a greenhouse directly onto your home is exciting! Let’s break down the key considerations for creating a thriving, cost-effective, and beautifully integrated attached greenhouse, keeping in mind the core concept of "greenhouses attached to houses."

I. Understanding the Basics & Benefits:

• What is an Attached Greenhouse? Clearly define what constitutes an attached greenhouse. Explain it’s essentially a greenhouse that shares at least one wall with an existing structure, usually a house. Highlight how this differs from freestanding greenhouses.
• Why Choose Attached? Focus on the advantages:
  • Energy Efficiency: Leveraging the house’s existing heating and cooling.
  • Convenience: Easy access from your home, especially in colder climates.
  • Aesthetic Appeal: Blending seamlessly with your home’s architecture.
  • Space Saving: Ideal for smaller properties.
• Potential Drawbacks: Acknowledge possible challenges:
  • Humidity Control: Managing moisture to prevent issues in the home.
  • Temperature Fluctuations: Ensuring consistent temperatures for plants.
  • Light Requirements: Optimizing sunlight exposure for different plant types.
  • Building Codes: Understanding local regulations and permits.

II. Costs Involved in Building Attached Greenhouses

• Initial Investment: Discuss the various cost aspects of building attached greenhouses:

  • Materials: This is a significant factor. Explore different materials such as:
    • Framing: Wood, aluminum, steel, PVC. Compare costs and durability.
    • Glazing: Polycarbonate, glass, polyethylene film. Weigh the pros and cons (insulation, light transmission, cost).
    • Foundation: Concrete slab, gravel base, or existing patio.
  • Labor: If hiring professionals, factor in costs for design, construction, and installation.
  • Permits and Inspections: Research local regulations and budget accordingly.

• Ongoing Expenses: Be sure to remind your readers that building attached greenhouses involves ongoing expenses:

  • Heating and Cooling: Although attached greenhouses leverage the house’s system, supplemental heating or cooling might be necessary.
  • Watering System: Drip irrigation or automated systems can save time and water.
  • Maintenance: Cleaning, repairs, and potential replacements.
  • Fertilizers and Soil Amendments: Essential for plant health.

• Cost-Saving Strategies: Provide actionable tips:

  • DIY vs. Professional: Assess your skills and consider partial DIY to save on labor.
  • Repurposed Materials: Explore using reclaimed wood or windows.
  • Bulk Buying: Purchasing materials in bulk can often reduce costs.

III. Inspiring Attached Greenhouse Ideas:

• Lean-to Greenhouses: Explain how these are built against an existing wall, often the easiest and most cost-effective option. Show example images of diverse lean-to designs.
• Gable Greenhouses: Showcase how these greenhouses are built with a peaked roof, providing more headroom and often a more traditional look.
• Sunroom Conversions: Describe how an existing sunroom can be converted into an attached greenhouse with modifications.
• Consider Design Choices:
  • Location: South-facing for maximum sunlight in northern hemispheres. Consider shade in warmer climates.
  • Size: Tailor the size to your needs and available space.
  • Doorway Access: Ensure convenient entry from both the house and the outside.
  • Ventilation: Incorporate vents and fans for optimal airflow.
• Interior Layout: Talk about how to maximize plant space
  • Shelving: Stacking plants vertically on shelves can make the most of limited space.
  • Hanging Baskets: Creating vertical interest and maximizing growing area.
  • Growing Beds: Raised beds or in-ground planting, depending on space and preference.
  • Pathways: Clear and accessible pathways for easy navigation.

IV. DIY Tips for Building Your Own Attached Greenhouse:

• Planning & Preparation:
  • Detailed Blueprints: Create or find detailed plans that fit your space and budget.
  • Material List: Compile a comprehensive list of all materials needed.
  • Tool Inventory: Ensure you have all necessary tools or consider renting.
  • Permitting: Research and obtain all necessary permits before starting construction.
• Step-by-Step Construction Guide: (Outline key steps – detailed instructions would be too extensive for this article)
  1. Foundation: Preparing and building the base.
  2. Framing: Constructing the frame (wood, metal, or PVC).
  3. Glazing: Installing the glazing material (polycarbonate, glass, etc.).
  4. Ventilation: Adding vents and fans.
  5. Sealing: Sealing gaps to prevent drafts and moisture.
• Essential Considerations:
  • Proper Drainage: Ensure adequate drainage to prevent water damage.
  • Structural Integrity: Build a strong and stable structure that can withstand weather conditions.
  • Insulation: Insulate well, especially in colder climates, to conserve energy.
  • Safety Precautions: Wear appropriate safety gear during construction.
• Troubleshooting: Anticipate potential challenges and provide solutions:
  • Leaks: How to identify and repair leaks.
  • Condensation: Managing condensation to prevent mold and mildew.
  • Temperature Regulation: Addressing temperature fluctuations.

V. Choosing the Right Plants for Your Attached Greenhouse:

• Consider Your Climate: Select plants that thrive in your local climate and the greenhouse environment.
• Light Requirements: Match plant needs to the available sunlight.
• Humidity Levels: Choose plants that tolerate the greenhouse’s humidity.
• Popular Plant Choices:
  • Vegetables: Tomatoes, peppers, cucumbers, lettuce, herbs.
  • Flowers: Orchids, succulents, geraniums, begonias.
  • Seedlings: Starting seeds for your garden or indoor plants.
• Planting Strategies:
  • Companion Planting: Grouping plants that benefit each other.
  • Crop Rotation: Rotating crops to prevent soil depletion.
  • Succession Planting: Planting crops at intervals to extend the harvest season.

So, whether you’re dreaming of fresh tomatoes in January or just a sun-soaked space to relax, attached greenhouses can be a fantastic addition to your home. Take these ideas and DIY tips, do a little planning, and get ready to enjoy the rewards of having a greenhouse attached to your house! Happy growing!
