Case Study: When Roof Design Becomes the Critical Path

On this Walnut project, the longest part of the process wasn't construction-it was planning.

Specifically, roof form and pitch.

The original roof concept prioritized cost efficiency.

During planning review, the City asked for a more unified roof geometry-without crickets-with careful attention to how the home would read from the street and relate to neighboring properties.

Walnut's planning department places a strong emphasis on neighborhood character and long-term street presence.

Early in this project, those comments felt like friction. Over time, we learned that understanding their priorities-and building working relationships-led to better outcomes for everyone involved.

After working through the constraints together, we reached a compromise:

• A marginal increase in cost
• Cleaner, more cohesive roof geometry
• A home that reads as intentional, not an afterthought

Lesson learned:

Most delays and cost overruns are decided before structural plans are finalized.

When planning intent, neighborhood context, and long-term appearance are addressed early, the City stops being an obstacle and becomes a partner.

Planning departments aren't only protecting individual homeowners.

They're protecting the long-term fabric of the city.
