Board approves full remodel at 521 Calle Corvo but narrows window change after extended debate
Loading...
Summary
After a prolonged debate about window historicity and a withdrawn roof exception, the board approved a remodel at 521 Calle Corvo including full window replacement subject to conditions: retain terracotta portal, maintain light-pattern/muntin proportions on primary facades, and specific sill-height and color conditions. The approval followed extensive testimony from the applicant and neighbors.
The Historic Districts Review Board approved a remodel at 521 Calle Corvo that allows the applicant to proceed with most exterior changes but applies conditions aimed at preserving the primary façade’s visual character.
Staff had flagged concerns about the applicant’s request for a standing-seam roof and wholesale window replacement on primary facades. The applicant’s architect, Raja Bose, withdrew the roof exception and agreed to restore the terracotta portal in kind; the remaining debate focused on whether the primary façade windows were original picture windows or later replacements and whether full replacement should be permitted.
Raja Bose presented evidence and photographs and asked the board to allow modern, metal-clad windows with a new divided-light pattern, arguing the existing windows are in poor condition and that modern replacements would be more durable and energy-efficient. “We are asking to change the original opening a little bit,” he said, and added that the design team had surveyed the streetscape to support the proposed approach.
Board members split over the degree of replication required. Several members pressed for replacing windows "in kind" on primary facades where historic material remained; others were persuaded by testimony about poor existing conditions and the applicant’s willingness to preserve the terracotta portal and to match muntin proportions. The board amended and refined a motion to permit full window replacement on the southern primary facade only if the new units maintain division patterns and proportions consistent across the facade; the kitchen window sill was addressed as a narrow exception (approved to be raised), while one modern picture window nearest the garage was treated as nonhistoric and allowed to be replaced to match the chosen pattern.
The board tied approval to several conditions: retain or replace the terracotta portal in kind; use cementitious stucco matching existing color; submit final window sash/muntin drawings that maintain the agreed division pattern for staff approval; and keep the prominent picture-window design on the portal elevation as the design intent while allowing the kitchen sill change. The motion passed after successive amendments and roll-call votes.
Public commenters, including neighborhood residents and owners, urged the board to balance preservation with the applicant’s ability to maintain the house as a lived-in home. Jordan Young and Elizabeth West spoke in support of thoughtful renovation that retains neighborhood character while allowing modernization where original fabric is demonstrably nonhistoric or deteriorated.
The board’s decision allows the project to proceed with the stated conditions; staff will review final window drawings and the stucco and trim colors before permits are issued.
