Collapsed Envelope Site — R8B

Collapsed Envelope Site — R8B

Collapsed Envelope Site — R8B

Early-stage screening shows that available as-of-right FAR collapses under R8B bulk controls, resulting in no viable buildable envelope.

This screening is limited to early-stage feasibility and precedes massing, underwriting, and formal due diligence. No architectural, legal, or financial conclusions are implied beyond an initial screening judgment.

Key Observations

Zoning & Use

The site is located within an R8B district, where residential use is permitted as-of-right. The existing residential building is conforming under current zoning provisions.

Bulk & Envelope

While residual as-of-right FAR remains unused, R8B bulk controls—including rear yard requirements, height limits, and mandatory setbacks—compress the buildable envelope to the point where additional floor area cannot be translated into viable building form.

The existing building reflects the practical envelope achievable under current R8B controls, even though theoretical zoning capacity remains.

Parking & Access

Parking requirements do not materially affect feasibility at the screening stage and do not alter the envelope outcome.

Primary Constraint

R8B rear yard, height, and setback controls structurally constrain the site such that residual as-of-right FAR cannot be translated into additional buildable volume.

Early Screening Verdict

STOP

Despite residual as-of-right FAR, the site fails early-stage screening due to structural envelope collapse under R8B bulk controls. No viable as-of-right expansion path exists without discretionary action.

Items Requiring Confirmation

None. Envelope constraints are determinative at the screening stage.
