A new story on an old house
Overstory started as a single-story Boulder house and gained a full new story, designed by HMH Architecture & Interiors. The new shell is wrapped in vertical wood siding over a black base, with black-framed windows and a thin canopy floating over a glass entry. Inside, the same language continues: a wood slat screen runs beside the black steel stair, filtering light between the living space and the stairwell rather than walling them apart.
Decisions made on site
The photographs from construction tell the story we care about: our crew on scaffolding hanging the entry canopy, the team from FS Woodworks cutting and fitting wood at benches set up inside the house, conversations happening on site where the decisions actually get made. Building a new story on top of an existing house means live loads, tight sequencing, and daily judgment calls. That is normal work for us, and Overstory wears it well. Completed in 2025, with photography by Devon Weatherwax.

What is pre-construction?
Pre-construction is the planning phase where design, budget, scope, and constructability are aligned before building begins. It typically includes budgeting, scheduling, coordination with the design team, site analysis, and early decision-making that helps establish a stronger foundation for the project overall.

Cost-plus vs fixed-price construction
Cost-plus construction allows projects to evolve transparently as design decisions are refined, while fixed-price contracts are typically best suited for fully defined scopes with limited change. For architecturally driven residential projects, cost-plus structures often provide greater flexibility and clearer visibility into how decisions impact the overall project budget.

How does Fernhill work with architects?
Fernhill works closely alongside architects throughout both design development and construction, helping support the project through constructability input, budgeting, coordination, and disciplined execution. The goal is always to protect design intent while ensuring the project remains aligned with the realities of construction.

Why involve a builder early in design?
Early builder involvement allows key decisions around constructability, cost, sequencing, and site logistics to be addressed while the design is still flexible. This helps reduce unnecessary redesign, maintain alignment with budget expectations, and create a smoother transition into construction.

What does a custom home cost in Boulder?
Custom home costs in Boulder can vary significantly depending on site conditions, design complexity, level of finish, and structural requirements. At Fernhill, projects typically begin around $700 per square foot, with highly design-driven homes often exceeding $1,000 per square foot depending on the level of customization, structural complexity, and material selection.
