Description

Siting and Setting Description: The property lies within a residential block in Boise's East End, following the neighborhood's angled street grid. It fronts E Jefferson St and occupies an approximately level lot with concrete sidewalks, a planted setback, mature trees, and alley service access. The documented neighborhood development era and construction date are not established in the supplied record. Main Building Description: The photographed resource is a two-story building at the intersection of E Jefferson Street and N Straughan Avenue. Its principal façade faces north, fronting E Jefferson St. The tall residence has an irregular, cross-gabled form, a broad street-facing porch, and projecting upper window bays beneath gabled roof forms. Narrow horizontal wall cladding, broad eaves, multiple-light upper sash, and a brick chimney remain visible. The rear views show the continuation of the two-story body and enclosed yard; a separate accessory building is not securely established. Character-Defining Features: – Two-story cross-gabled massing with a lower porch roof. – Broad porch supported by square posts. – Projecting upper window bays and grouped sash. – Horizontal wall cladding and a brick chimney. Summary of Known or Observed Alterations: – Unknown date: Replacement roofing and some replacement window or storm assemblies are apparent; their dates are unknown. – Unknown date: Work on the adjoining parcel changes the immediate setting but does not alter the house itself. Accessory Building Description: – (1) main house; preliminary recommendation: contributing, subject to address and construction-date confirmation

Justification of Significance and Integrity

Statement of Significance: The construction date is unknown. The house is a prominent corner residence whose height, complex gabled form, porch, and wood-detail vocabulary distinguish it within the block. These features support a preliminary district contribution under Criterion C as an intact example of an early residential type. Its construction date, district period, and the address discrepancy must be confirmed before a final determination. Contributing Determination: This is a preliminary contributing recommendation. The recommendation applies only to the main building unless an accessory resource is expressly evaluated. Confirm the construction date, applicable district boundary, and period of significance before finalizing the ICRIS field. Evaluation of Integrity under Criterion C: – Location: The resource remains on the mapped parcel and maintains its relationship to the street and alley. Historic location has not been independently documented. – Design: The visible massing, roof form, openings, and entrance treatment continue to convey the identified two-story gabled residence with Craftsman influence. Any unresolved feature is named above. – Setting: The sidewalk, planted setback, mature canopy, nearby dwellings, and alley service pattern preserve a coherent residential setting. Recent work on adjoining parcels is noted where visible. – Materials: The photographs support the present material identifications of narrow horizontal clapboard or lap siding; substrate not fully evident and asphalt shingles. They do not establish which components are original. – Workmanship: Visible trim, porch elements, roof-edge details, and wall treatments retain evidence of the building's exterior design; concealed or replaced work is not assumed. – Feeling: The building's scale, setback, roof form, and street presence continue to express an older residential character except where the record remains pending. – Association: Under the proposed Criterion C basis, the relevant association is with the two-story gabled residence with Craftsman influence type expressed by the surviving form and detail. No architect, builder, event, or person association is established.
