Build Wealth From the Ground Up. Invest With Cost Certainty.
Terrapin Construction Group brings investors, family offices and co-GP partners into design-build development projects before capital is committed, with real cost data, one contract and one point of accountability from design through delivery.
How Does the TCG Investor Program Work?
TCG lists pre-development projects where the sponsor is seeking equity, co-GP or debt partners. We price every scheme in-house, so investors see a construction budget built from the cost of work, not a dollar-per-square-foot guess. Detailed cost models and pro formas are shared with qualified parties under NDA.
Accredited investors, family offices, developers seeking co-GPs, lenders and CRE brokers.
Multifamily, mixed-use and commercial projects in schematic design or entitlement.
ROM cost by option, pro forma, risk register and a design-build schedule, under NDA.

Explore the Four Design Schemes
The sponsor is testing how many levels of structured parking to build and whether to add an 8th floor restaurant. Select a scheme to see how the building stacks up.
Scheme 1.1: Three-level podium
Every scheme includes ground floor retail, two stair and elevator cores and a rooftop amenity deck. Cost and return figures for each scheme are in the investor package.
The Railyards Are Doubling the Size of Downtown Sacramento
The site sits on the 7th Street corridor between downtown and the Railyards, a 240-acre former rail yard now anchored by a stadium, a hospital campus and California's second busiest rail station.

Kaiser campus opens (target)
About 3,000 health care jobs, with planned Valley Rail service adding commuter links to Stockton and the Bay Area.
Cost Certainty Before Capital Is Committed
Most development deals fail on cost, not demand. TCG prices the building before investors commit, then holds the number through design-build delivery.
Price every scheme
In-house preconstruction prices each massing option to the cost of work, so the pro forma rests on real numbers.
Lock a GMP
One design-build contract and a guaranteed maximum price, with architecture, engineering and construction under one roof.
Why this protects your capital
Construction contingency is a project fund, not contractor profit. Any unused balance at closeout returns 100% to the owner. Compare delivery methods in our guide to design-build vs CM at risk vs design-bid-build.

Investor Questions
The project
What is the 707 E Street Sacramento development?
It is a proposed 8-story mixed-use apartment building at 707-709 E Street in Sacramento, California, with 90 to 120 studio, one-bedroom and two-bedroom apartments over a concrete podium with ground floor retail and structured parking. It is in pre-development and the sponsor is seeking capital partners.
Where is the site relative to the Sacramento Railyards?
The site is at the corner of 7th and E Streets on the north edge of downtown Sacramento, along the 7th Street corridor into the Railyards, where Republic Stadium and the Kaiser Permanente Railyards Medical Center are under construction.
What design schemes are being studied?
Four schemes test two questions: whether to build two or three levels of concrete podium, which trades parking stalls for apartments, and whether to include an 8th floor restaurant. Apartment counts range from 90 to 120 and parking from 22 to 40 stalls.
What is the project timeline?
The project is in schematic design. Timing to construction depends on entitlement, financing and the final scheme. TCG's design-build approach lets design, permitting and procurement overlap to shorten the schedule.
Investing
How can I review the cost estimate and pro forma?
Request the investor package or book a call on this page. Qualified parties receive the cost model, pro forma and risk register after signing a non-disclosure agreement.
Does TCG offer securities or take investor money?
No. TCG is a contractor, not a broker-dealer or fund. Any investment is offered only by the project sponsor through its own offering documents, typically to accredited investors. Nothing on this page is an offer to sell or a solicitation to buy securities.
Who can invest?
Eligibility is set by the project sponsor's offering documents. Most private real estate offerings of this type are limited to accredited investors.

What happens to unused construction contingency?
Construction contingency is a project fund for unforeseen conditions. Any unused balance at closeout returns 100% to the owner.
Can TCG evaluate a development deal I am already looking at?
