Top 7 Features of Modern Granny Flats

Granny flats, also known as accessory dwelling units (ADUs), have evolved from simple secondary accommodations into modern, stylish, and functional living spaces. These units offer a versatile solution for various needs, including housing aging parents, generating rental income, or providing a private retreat. Modern granny flats incorporate innovative design features and amenities that enhance comfort, functionality, and aesthetics. Here are the top seven features that make modern granny flats stand out.

Functional Features in Modern Granny Flats

Open Floor Plans

Modern granny flats often utilize open floor plans to maximize space and create a sense of openness and airiness. This design approach eliminates unnecessary walls and barriers, allowing for a more fluid and flexible living area.


  • Enhanced Light and Airflow: Open floor plans facilitate better natural light and ventilation, creating a brighter and more comfortable environment. With fewer walls to block windows, light can flow freely, reducing the need for artificial lighting during the day.
  • Versatility: The flexible layout allows for easy rearrangement of furniture and multifunctional use of the space. You can easily change the room’s purpose or decor without structural changes.
  • Social Interaction: Open spaces encourage social interaction and make the unit feel more inclusive and connected. This is especially beneficial for family gatherings or entertaining guests, as it allows for seamless movement and communication.

Implementation Tips:

  • Minimalist Design: Keep furniture and decor minimal to avoid clutter and maintain the open feel. Opt for pieces that serve multiple purposes, such as a sofa that can double as a guest bed.
  • Consistent Flooring: Use the same type of flooring throughout the unit to create visual continuity. This helps make the space feel larger and more cohesive.
  • Strategic Furniture Placement: Arrange furniture to define different zones without creating physical barriers. For example, a rug can demarcate a living area, while a dining table can separate the kitchen space.

Energy Efficiency

Energy efficiency is a key consideration in modern granny flat design. Incorporating energy-efficient features reduces utility costs and minimizes environmental impact, making the living space more sustainable.


  • Lower Utility Bills: Energy-efficient features help reduce heating, cooling, and electricity costs. This makes the unit more affordable to live in over time.
  • Environmental Impact: Sustainable design practices contribute to reducing the carbon footprint of the dwelling. By using less energy, you contribute to conserving resources and protecting the environment.
  • Enhanced Comfort: Energy-efficient homes maintain more consistent indoor temperatures and air quality. Proper insulation and energy-efficient windows keep the interior comfortable year-round, regardless of the weather outside.

Implementation Tips:

  • Insulation: Ensure the unit is well-insulated to prevent heat loss in winter and keep cool in summer. This includes insulating walls, roofs, and floors.
  • Windows and Doors: Install double-glazed windows and well-sealed doors to improve thermal performance. These features help maintain indoor temperatures and reduce drafts.
  • Appliances: Use ENERGY STAR-rated appliances to reduce energy consumption. These appliances are designed to operate more efficiently, saving energy without sacrificing performance.

Smart Home Technology

Incorporating smart home technology into granny flats can significantly enhance convenience, security, and efficiency. These systems allow residents to control various aspects of their home environment with ease.


  • Convenience: Smart home devices provide remote control and automation of lighting, heating, cooling, and security systems. This can be done via smartphone apps or voice commands, making daily life more convenient.
  • Security: Advanced security features such as smart locks, cameras, and alarms offer enhanced protection. You can monitor your home remotely and receive alerts if any unusual activity is detected.
  • Energy Management: Smart thermostats and lighting systems help optimize energy use and reduce waste. For example, lights can be set to turn off automatically when no one is in the room, and thermostats can adjust the temperature based on occupancy.

Implementation Tips:

  • Smart Lighting: Install smart bulbs and switches to control lighting remotely or set schedules. This allows you to manage lighting levels and save energy.
  • Smart Thermostats: Use smart thermostats to regulate temperature based on occupancy and preferences. They can learn your schedule and adjust settings to maximize comfort and efficiency.
  • Voice Assistants: Integrate voice-activated assistants like Amazon Alexa or Google Home for hands-free control of smart devices. These assistants can control multiple devices, provide information, and even play music.

Accessible Design

Modern granny flats often incorporate accessible design features to ensure that the space is comfortable and functional for people of all ages and mobility levels. This approach makes the unit suitable for aging in place or accommodating individuals with disabilities.


  • Inclusivity: Accessible design ensures that the living space is usable by everyone, regardless of age or physical ability. This includes features that accommodate wheelchairs, walkers, and other mobility aids.
  • Safety: Features like grab bars, non-slip flooring, and step-free entries reduce the risk of accidents. These modifications can prevent falls and make daily activities easier and safer.
  • Future-Proofing: Designing with accessibility in mind ensures that the unit remains functional as needs change over time. This is particularly important for aging homeowners who wish to remain in their homes as long as possible.

Implementation Tips:

  • Wide Doorways and Hallways: Ensure doorways and hallways are wide enough to accommodate wheelchairs and walkers. This typically means at least 36 inches wide.
  • Step-Free Entrances: Design entrances without steps to provide easy access. Ramps or level entrances are ideal for this purpose.
  • Accessible Bathrooms: Include features like walk-in showers, grab bars, and raised toilets. These elements make the bathroom safer and easier to use for individuals with limited mobility.

To ensure privacy, consider adding landscaping elements like tall shrubs or fences, using frosted or tinted windows, and incorporating soundproofing materials. Designing a separate entrance and outdoor area can also enhance privacy for both the main house and the granny flat.

Eco-friendly materials for granny flat construction include bamboo flooring, recycled metal roofing, reclaimed wood, and low-VOC (volatile organic compounds) paints. These materials are sustainable and contribute to a healthier living environment.

To make a small granny flat feel more spacious, use light colors for walls and decor, incorporate mirrors to reflect light, and choose multi-functional furniture. Open floor plans and large windows can also enhance the sense of space.
