Boston South End Penthouse Hits $8M, Church Conversion

Why This $8M South End Penthouse Costs So Much

Although $8 million is a headline number in Boston, this South End penthouse is priced on a rare convergence of skyline-facing exposures, glass-walled views, and immediate access to the SOWA arts district, dining, shopping, and the MBTA Red Line. Boston’s broader housing market context matters too, with the single-family median price now surpassing $1 million amid strong demand.

Location-Driven Scarcity

Exposure Premium

East and west exposures capture sunrise-to-sunset panoramas, while select bedrooms face the Financial District.

The position at the South End, South Boston, and Fort Point edges compresses commute time and concentrates demand.

Construction and Lifestyle Costs

Luxury Finishes at Scale

Floor-to-ceiling windows, high ceilings, and white oak floors frame panoramic views across an open plan stretching 40-plus feet with a gas fireplace.

Miele kitchens, marble heated bath floors, custom closets, and 2021-2022 systems align with concierge, fitness, pool, and garage parking.

Two covered garage parking spaces are included with the home, underscoring the parking premium in this part of the South End.

How the Holy Trinity Church Became Luxury Condos

When Holy Trinity Church closed in 2008 after the Archdiocese of Boston moved to shutter the parish, a 150-plus year community anchor entered a new and irreversible phase.

Sale and conversion pressure

After four years of parishioner efforts, the building was sold in 2014 for $7 million.

Developers advanced The Lucas at 136 Shawmut Avenue, completed in 2017.

Similar church-to-residential projects have drawn Tax Increment Financing alongside private capital.

Design choices under scrutiny

Finegold Alexander and Associates led an adaptive reuse plan that treated the facade as the organizing datum.

Preservation ethics were tested by inserting residential volume while keeping Gothic arches and buttress rhythms legible.

Key preserved elements

• Arches retained over private street entrances.
• Bell tower volume repurposed for one unit.

A glass-and-steel addition enabled decks, while the adjacent rectory joined the plan overall.

What’s Original vs. Newly Built Inside the Penthouse

The church’s preserved Gothic shell now frames an interior that was largely rebuilt to meet luxury condo expectations.

What Stayed Intact

Gothic tracery was replicated in window profiles across units.

Stained-glass openings were retained and then fitted with new custom panels.

The fifth-floor octagonal vaulted drum survives as a signature volume with 360-degree views.

Outside, the restored 19th-century façade and a medieval-style courtyard preserve the church’s presence.

What Was Newly Built

Behind the shell, the 2,600-plus-square-foot penthouse was newly constructed as a single-level plan with central air and underground parking.

Contemporary kitchens add top-tier appliances and light fixtures.

Primary spaces run more than 40 feet with floor-to-ceiling windows, wood flooring, and gas fireplaces.

Private terraces and rooftop cabanas extend the rebuild, alongside spa-like baths.

South End vs. Seaport: Which Luxury Lifestyle Wins?

South End vs. Seaport has become a high-stakes decision as Boston’s premium market tightens and pricing spreads widen. Two adjacent luxury districts now diverge in ways that meaningfully affect lifestyle and resale.

South End prioritizes historic brownstones and cultural vibes, with galleries, boutiques, and tree-lined blocks. Seaport emphasizes new-construction towers and waterfront amenities along the Harborwalk.

Housing Tradeoffs

Residence and service

South End offers character and renovation leverage, with more variety from block to block. Seaport leans into full-service living with concierge, gyms, lounges, and garage parking.

Echelon and 100 Pier 4 exemplify Seaport’s highest price-per-square-foot positioning. Their value proposition is convenience, finish level, and building-driven amenities.

Access and Feel

Seaport pairs Silver Line commutes with under-15-minute trips to Logan. The area reads as newer and more future-oriented, especially around Fan Pier.

South End stays highly walkable to downtown and tends to feel more established. Its arts community and streetscape create a neighborhood-first atmosphere.
