Seattle Night Gray ColorPlus HardiePlank With HydroGap, Front Gable Shingles & Arctic White Trim

This Seattle, WA project was built as a complete exterior case study, not just another list of siding materials. KV Construction approached the work as one exterior system, coordinating the main cladding with the documented preparation, weather protection, transitions, and finish details.

Seattle homes regularly deal with wind-driven rain and shaded walls that dry slowly, making the drainable HydroGap layer a practical part of the assembly.

The core installation centered on 8 1/4-inch ColorPlus HardiePlank with a 7-inch reveal, Night Gray. Several project-specific details shaped the scope: straight-edge shingles at the front gable and a 5/4×8 belly-band detail added profile changes to the front elevation. Together, those choices gave the project a clearer architectural identity while keeping the scope grounded in the actual materials and processes used on site.

A Drainable Wall System Behind ColorPlus Siding

The project started with the preparation that mattered for this specific exterior: existing siding removed before the new drainable WRB and fiber cement system. That work gave the new siding system the right foundation instead of treating the project as a surface-only update.

Weather Barrier, Flashing, and Rain Control

Pacific Northwest exterior work has to respect water. On this project, the documented supporting system included Benjamin Obdyke HydroGap, HydroTape DS, 2-inch HydroFlash GP, 26GA flashing, Z-metal, and QUAD MAX. Those layers and transition details help the siding, openings, corners, penetrations, and adjoining surfaces work together through the region’s long wet season.

Material Choices That Fit the Project

The main exterior choice was 8 1/4-inch ColorPlus HardiePlank with a 7-inch reveal, Night Gray. KV Construction paired that with Arctic White Hardie trim and exterior blocks. The profile, spacing, texture, trim depth, and color or finish all influence how the building reads from the street, while the supporting details protect the edges where materials meet.

Details That Made This Project More Complete

Several project details made this scope more complete: Straight-edge shingles at the front gable and a 5/4×8 belly-band detail added profile changes to the front elevation. These items are important because siding projects often become most complex at soffits, openings, rooflines, lower-wall transitions, gutters, or places where two materials and profiles meet.

Outcome and Property Owner Value

The finished scope gives the property a more coordinated exterior, with the visible siding and the supporting details tied into one project. It is the kind of work KV Construction wants to be known for: practical, well-organized, and built around durable siding systems suited to Pacific Northwest weather.
