Embarking on a home addition is an exciting venture that promises more living space and increased property value. While aesthetics and layout often take center stage, the unseen mechanical systems—plumbing, electrical, and HVAC—are the true foundation of a comfortable and functional space. Proper planning for these core components is critical to avoid future complications and ensure your new addition integrates perfectly with your existing home.
Key Mechanical Systems to Plan for Your Home Addition
Extending Your HVAC System
Ensuring your new space is as comfortable as the rest of your home starts with the HVAC system. We begin by performing a load calculation to determine if your current unit can handle the increased square footage. This analysis informs whether we can extend existing ductwork or if a separate, zoned system or a ductless mini-split is a more efficient solution.
Upgrading Your Electrical Panel & Wiring
Modern living demands significant electrical power, and your home addition is no exception. We assess your current electrical panel’s capacity to ensure it can support new circuits for outlets, lighting, and any special appliances. This planning phase is crucial for meeting modern building codes and preventing the risk of overloading your home's main circuit breaker with the increased demand.
Planning for New Plumbing Lines
If your addition includes a bathroom, wet bar, or laundry room, integrating new plumbing is a primary consideration. Our process involves carefully mapping out how to extend supply and drain lines while maintaining proper water pressure and ensuring correct venting. We strategically tie into your existing sewer or septic system to ensure flawless function without disrupting your current infrastructure.
Ensuring Seamless System Integration
The greatest challenge with mechanical systems is ensuring they all fit and function together within the same walls and ceilings without conflict. Our integrated design-build approach is a significant advantage here, as our entire team collaborates from a single, unified plan. This prevents issues like plumbing pipes and ductwork competing for the same space, ensuring a smooth and efficient installation process.
