I would focus first on the systems that protect the home from moisture, wildfire smoke and embers, indoor-air-quality problems, and plumbing leaks—because those decisions are much harder and more expensive to correct after construction is complete. In this episode, I'm walking through the healthy-home strategies I would prioritize for my own family while working within a realistic budget. My choices are shaped by Southern California's small lots, seismic requirements, coastal moisture, and wildfire risk, but the planning principles can be adapted to other climate zones. I would start with a two-story home on a concrete foundation to make the most of a limited Orange County lot. If feasible, I would raise the interior floor with a taller stem wall and install a vapor barrier below the slab so moisture in the soil is separated from the concrete and the living space above it. For the enclosure, I would build watertight and airtight exterior walls using a well-detailed water-resistive barrier such as the ZIP System or a self-adhered membrane. I would add exterior rigid mineral-wool insulation for thermal performance and fire resistance, then use a sealed, unvented attic to reduce the pathways through which wildfire embers and smoke can enter the home. Inside, I would choose paperless drywall to reduce the amount of paper facing that can support problems when moisture reaches the back of a wall. Quality control would be part of the build—not something left until a problem appears. I would leak-test the exterior walls, windows, and roof before insulation and drywall conceal the assemblies. Finding and correcting a leak during construction provides far more peace of mind than discovering hidden water damage five or ten years later. I would also invest in a properly calculated mechanical design based on the home's actual enclosure and climate. In wildfire country, that includes dampers that can close exterior openings, along with effective filtration, fresh-air ventilation, dehumidification, and an ERV designed to work with an airtight home instead of treating each piece of equipment separately. Finally, I would create a whole-home leak-management plan. A floor drain in the laundry room, a whole-home leak detector and automatic shutoff, separate irrigation controls, and accessible plumbing connections can limit damage from a failed appliance or supply line. When the family leaves for vacation, the domestic water can be shut off without affecting the landscaping. A healthy home should feel like a sanctuary—not a source of fear about water damage, mold, toxins, or hidden failures. The goal is to make the highest-value decisions early so the enclosure, mechanical systems, and plumbing protections work together for the family living inside. In today's episode, we're talking about: - How lot size, climate, and budget shape healthy-home priorities - Why a raised foundation and under-slab vapor barrier help manage moisture - How airtight walls, exterior insulation, and an unvented attic support resilience - Why leak testing should happen before insulation and drywall - What a wildfire-aware mechanical and ventilation strategy can include - How whole-home leak detection and shutoff systems create peace of mind

You may already have an architect and a builder—but does that mean you have every perspective your healthy home needs? Not necessarily. The real question is whether your plans fully document your materials, quality standards, and building-science expectations before construction begins.

In this episode, Christine breaks down what your architect and builder should each be responsible for, why permit-ready plans often leave major gaps, and how to tell whether your existing team is equipped to deliver the healthy home you expect.

A strong architect should do far more than create a beautiful layout and submit plans for permitting. Your schematic design, design development, and construction documents should capture the decisions that matter—from the foundation and exterior walls to insulation, waterproofing, mechanical systems, plumbing, flooring, and material specifications. If those expectations are not documented, they can be missed, miscommunicated, or priced inaccurately.

Your builder's role is to implement those construction documents, manage the schedule and subcontractors, and send documented requests for information back to the architect when questions arise. When plans lack detail, builders are forced to make decisions during construction based on habit or a previous project—and that may not align with the healthier materials or methods you intended.

If your architect provides robust plans, specifications, material selections, quality-control details, and construction administration—and your builder understands healthy-home building science—you may not need a consultant. If those pieces are missing, a healthy-home consultant can help close the gaps before they become expensive problems on site.

In today's episode, we're talking about:

- How to assemble the right team for a new build or major renovation

- The architect's role from schematic design through construction documents

- Why permit-ready plans may not be detailed enough to protect your expectations or budget

- How specifications and material selections create clearer, more accurate bids

- Why construction administration and the RFI process matter

- What your builder should implement—and what should not be improvised mid-build

- The signs that your team is complete and when a healthy-home consultant can add value
