The Impact of Impervious vs. Pervious Spaces on Your Floor Plan

When it comes to designing your dream home, the floor plan holds both impervious and pervious space. Why is this important? You are only allowed a certain amount of penetrable space in your lot size. Vice versa the same with impenetrable area.

Defining Impervious and Pervious Spaces:

  • Impervious Spaces: These are surfaces that don't allow water to penetrate, such as roofs, driveways, and concrete patios. Impervious surfaces can contribute to issues like water runoff, which may lead to erosion and water pollution.

  • Pervious Spaces: In contrast, pervious spaces allow water to infiltrate the ground. These include green spaces, gardens, and permeable surfaces like gravel driveways. Pervious spaces can aid in water absorption, reduce runoff, and contribute to a more sustainable environment.

Restrictions on impervious square footage aim to balance urban development with environmental conservation and sustainability. By limiting impervious surfaces, communities can promote responsible land use, reduce environmental impact, and create more resilient and livable spaces. These regulations play a crucial role in shaping the future of urban and suburban landscapes.

Environmental Impact:

  • Impervious Spaces: High amounts of impervious surfaces can contribute to the urban heat island effect, where built-up areas experience higher temperatures than their natural surroundings. Additionally, excessive impervious surfaces can lead to increased storm water runoff, potentially causing flooding and water pollution.

  • Pervious Spaces: Integrating pervious spaces into your floor plan can mitigate these environmental impacts. Gardens, grassy areas, or permeable materials can help absorb rainwater, reduce runoff, and promote a healthier local ecosystem.

Design Aesthetics:

  • Impervious Spaces: Traditional materials like concrete and asphalt are common choices for impervious surfaces. While they provide a durable and low-maintenance option, they may contribute to a more rigid and urban aesthetic.

  • Pervious Spaces: Incorporating pervious spaces allows for a more diverse and visually appealing landscape. Gardens, lawns, or even permeable pavers can introduce a softer, natural element to your floor plan, enhancing the overall aesthetics of your home.

Outdoor Living Experience:

  • Impervious Spaces: Patios, decks, and other impervious surfaces are popular for outdoor living spaces. While they provide functional areas for activities, they may require additional considerations for heat absorption and water runoff.

  • Pervious Spaces: Consider integrating pervious materials like permeable pavers or creating green spaces for outdoor activities. This not only enhances the outdoor living experience but also contributes to a more environmentally friendly and sustainable setting.

As you envision your floor plan, the distinction between the two spaces offers an opportunity to create a home that is both functional and environmentally conscious. Striking the right balance between these two types of spaces allows you to design a home that not only meets your lifestyle needs but also contributes to a sustainable and resilient community. Ultimately, the thoughtful integration of of these elements in your floor plan can lead to a home that is both a sanctuary for you and a positive force for the world around you.
