Wellesley New Construction Tracker
This map shows off-market and upcoming new construction homes in Wellesley, Massachusetts—properties in planning, permitting, or early construction that often never appear on public listing sites.
New construction pricing in Wellesley varies by zoning and location. SR10 homes typically sell between $2.5M–$3.3M, SR15 homes range from $3.3M–$4.2M, and SR20+ properties generally start at $4.2M and up, depending on lot size, neighborhood, and architectural detail.

Conforming House Size by Zoning District
Wellesley's TLAG (Total Living Area & Garage) formula determines the maximum buildable square footage on any given lot. The district your teardown sits in directly determines what a builder can construct — and therefore what you can buy. Knowing which zone a site is in before you make an offer is essential.
TLAG = Total Living Area & Garage. The calculation is more nuanced than square footage alone — it factors in finished basement space, garage area, and accessory structures. Always verify with a builder before making assumptions about what can be built on a specific lot. The official Town of Wellesley TLAG worksheet is available at wellesleyma.gov. Our team can walk you through any specific site's buildable envelope before you commit.
Built from the ground up — not scraped from MLS.
Most new construction searches surface the same public inventory every other buyer is already tracking. This map is different. It is built and maintained by Adler Connolly² at MGS Group Real Estate — a team that actively monitors Wellesley's building pipeline through four primary sources, not listing feeds.

For Luxury Buyers (SR20+)
For buyers targeting luxury new construction in Wellesley, early access matters even more. Many SR20+ homes are spoken for well before completion, often through quiet conversations between builders and well-informed local agents. These homes can offer larger lots, custom architecture, and premium locations that rarely reach the open market.
Luxury buyers who engage early may have the opportunity to influence floor plans, finishes, or timelines, or secure a property before pricing fully reflects market demand. Understanding what’s in the pipeline—rather than what’s already listed—can make a meaningful difference in both selection and long-term value.
Why Local Expertise Matters
Online listings only show a small portion of what’s actually happening in Wellesley. Many new construction opportunities are driven by permit activity, builder schedules, zoning considerations, and neighborhood dynamics that don’t appear on public websites.
Working with a local real estate professional who tracks every project in the pipeline gives buyers a clear advantage. That insight helps identify opportunities earlier, assess true value, and avoid overpaying once competition intensifies. In a market as tight and nuanced as Wellesley, real-time, local knowledge is often the difference between finding the right home and missing it entirely.

Frequently Asked Questions About Off-Market New Construction
What is off-market new construction?
Off-market new construction refers to homes that are not publicly listed on the MLS. These may include pre-release homes, upcoming builder phases, or properties marketed quietly through agent and builder relationships.
How do buyers find new construction before it hits the MLS?
Buyers gain early access by working with agents who have direct builder relationships, track development permits, and monitor upcoming releases — like our New Construction Tracker.
Is off-market new construction cheaper?
Not always cheaper, but buyers often get better lot selection, incentives, and negotiating power before public demand increases.
How often is the new construction tracker updated?
Our tracker is updated weekly as new opportunities become available and existing homes are sold or released publicly.
Do I need to use a buyer’s agent for new construction?
Yes — builders represent their own interests. Having a buyer’s agent ensures pricing guidance, contract protection, inspections, and advocacy throughout the build process.
How do buyers find off-market homes in Wellesley?
Most off-market homes are found through local relationships, permit tracking, and direct communication with builders—not online listings. Many never appear publicly.
Do all new construction homes in Wellesley get listed online?
No. Many new builds are sold before completion or quietly marketed to qualified buyers, especially in SR20+ neighborhoods.
What do SR10, SR15, and SR20 zoning mean?
These zoning categories impact lot size, setbacks, and allowable home size. They also strongly influence pricing, privacy, and neighborhood character.
Can buyers secure a home before construction is complete?
Yes. Early buyers may secure a property during permitting or early construction and sometimes influence layout, finishes, or timing.
Why is working with a local agent important for new construction?
Local professionals track permits, builder activity, and zoning changes—information not available on national websites. That insight often leads to earlier access and better outcomes.
