Build a Custom Design Home for a Growing Family: Duplex vs. Single-Storey

Updated: May 16

When it comes to creating a home for a growing family, designing the right type of dwelling is crucial. . In our last discussion, "Architect Designed Home Tips: Essential Features for Your Growing Family," we explored essential elements that contribute to a functional and nurturing family environment, such as the importance of a spacious yard, family-friendly living room, sufficient bedrooms for every family member, an open-plan kitchen, and ample storage. Today, we build upon these foundational principles as we delve into the comparison between duplex and single-storey homes. This analysis will help you understand how each home type aligns with the needs and dynamics of a growing family, using the insights from our previous blog as a guiding compass.

Duplexes and single-storey homes are two popular options, each with unique advantages. Let’s delve into how these options fare in terms of space, comfort, and design, especially when considering a custom home design approach.

Duplex: A Tale of Two Homes

A duplex is essentially two homes in one structure, offering a blend of privacy and proximity. This design is perfect for families who need separate living areas within the same property.

Advantages of Building a Duplex:

  • Custom Design Home Advantage: A custom design duplex enables each unit to be tailored to the specific needs of family members or potential renters.

  • Flexibility and Income: Live in one unit and rent out the other, providing a source of income.

  • Space Efficiency: Ideal for urban settings where land space might be limited.

Architectural Considerations:

  • Soundproofing and Privacy: An architect builder can incorporate soundproofing materials and design strategies to ensure privacy between units.

  • Customization: An architect designed home in a duplex format allows for personalization in each unit, matching the individual needs and style preferences of its occupants.

Single-Storey Dwelling: Comfort and Accessibility

Single-storey homes are celebrated for their ease of access and open-plan designs, making them ideal for families with young children or elderly members.

Advantages of a Single-Storey Home:

  • Safety and Accessibility: With no stairs, these homes are safer for children and more accessible for all.

  • Ease of Maintenance and Living: Less complex structures make for easier maintenance and cleaning.

Architectural Considerations:

  • Expansive and Open Design: An architect can design a single-storey home with large, open living spaces, fostering a sense of togetherness for the family.

  • Integration with Outdoor Spaces: The design can seamlessly blend indoor and outdoor spaces, perfect for family activities.

Custom Home Design Approach: Tailoring to Your Family’s Needs

Whether building a duplex or a single-storey home guided by a skilled architect or custom home builder, ensures that the space is tailored to the unique dynamics and needs of your growing family.

Role of the Architect Builder:

  • Understanding Family Dynamics: An architect builder can grasp the nuances of your family's lifestyle, ensuring the design supports your day-to-day life.

  • Future-Proofing: They can also plan for future changes, such as family expansion or evolving needs, making your home adaptable over time.

Custom Home Builder Collaboration:

  • Quality and Craftsmanship: A custom home builder brings the architect's vision to life, ensuring the highest standards of quality and craftsmanship.

  • Personalization: They can adapt construction techniques and materials to fit your specific requirements, be it for a duplex or a single-storey home.
