our proprietary technology and design and engineering expertise, we modify&nbsp;code-engineered&nbsp;cargo shipping containers
and purpose-built modules for use for safe and sustainable commercial, industrial and residential building construction. Rather
than consuming new steel and lumber, our proprietary technology and design and engineering expertise allows for the redesign,
repurpose and conversion of heavy-gauge steel cargo shipping containers into SGBlocks&trade;, which are safe green building blocks
for commercial, industrial, and residential building construction. Our technology and expertise is also used to purpose-build
modules, or prefabricated steel&nbsp;modular units customized for use in modular construction (&ldquo;SGPBMs&rdquo; and, together
with SGBlocks&trade;, &ldquo;Modules&rdquo;), primarily to augment or complement an&nbsp;SGBlocks&trade;&nbsp;structure.&nbsp;Our
core customer base is comprised of architects, landowners, builders and developers who use our Modules in commercial and residential
structures. Our operating model combines product design and outsourcing of the modifications and finish out of Modules using proprietary
algorithms developed by us to produce and deliver Modules across the country. We believe this combination enables us
to generate economies of scale while maintaining high customer service levels in the environmentally-friendly construction space.</FONT></P>

to October 2019, our business model was solely a project-based construction model pursuant to which we were responsible for
the design and construction of finished products that incorporated our technology primarily to customers in the multi-family
housing, restaurant, military and education industries throughout the United States. In October 2019, we changed our business
model for our residential building construction to a royalty fee model when we entered into a five year exclusive license
(the &ldquo;License Agreement&rdquo;) with CPF GP 2019-1 LLC (&ldquo;CPF&rdquo;) pursuant to which CPF licensed on an
exclusive basis our proprietary technology, intellectual property, any improvements thereto, and any related permits, with
the right to develop and commercialize products in the United States and its territories within the field of design and
project management platforms for residential use, including, without limitation, single-family residences and multi-family
residences, but specifically excluding military housing.&nbsp;&nbsp;CPF, at the time the License Agreement was entered into,
was already a significant customer for our Modules and had completed a $5.0 million equity financing to develop a 302-unit
multifamily project in Sullivan County, New York.&nbsp; Now, in the United States with respect to residential construction
(other than residential construction for the military) we are no longer responsible for constructing the Modules that are
based on our technology or the related costs and instead that service is performed by CPF and its subcontractors and our
revenue for such residential construction is no longer generated from sales of products direct to the end customer but
instead is generated from royalties received from CPF based on the gross revenue that CPF receives from sales of products
that are based upon our technology.</FONT></P>

with the Public Offering, we sold&nbsp;857,500&nbsp;shares of our common stock at a public offering price of $3.00&nbsp;per share,
resulting in aggregate net proceeds of $2,117,948&nbsp;after deducting underwriting discounts and commissions and other expenses
related to the Public Offering.&nbsp;We incurred&nbsp;a total of $454,552&nbsp;in issuance costs in connection with the
Public Offering and no warrants to purchase were issued to the underwriters.&nbsp;The proceeds of the Public Offering were used
as follows: (i) $480,770 to repay the outstanding principal amount of an outstanding debenture (the &ldquo;Debenture&rdquo;);
(ii) a portion to fund our obligation to our licensee under the terms of&nbsp;the Loan Agreement&nbsp;with CPF pursuant to which
we agree to loan CPF GP a principal amount of $750,000 at an annual interest rate of five percent (5%), with a maturity date of
July 31, 2023; and (iii) the remaining net proceeds for general working capital purposes.</FONT></P>

offering price of $100,000,000. In no event will we sell securities with a value exceeding more than one-third of our &ldquo;public
float&rdquo; (the aggregate market value of our outstanding common stock and any other equity securities that we may issue in
the future that are held by non-affiliates) in any 12-calendar month period so long as our public float remains below $75.0 million.
In this prospectus, we refer to the common stock, preferred stock, debt securities, warrants and units collectively as the &ldquo;securities&rdquo;.
This prospectus provides you with a general description of the securities we may offer. Each time we offer securities under this
shelf registration, we will provide a prospectus supplement that will contain specific information about the terms of that offering.

Company is in the business of modifying cargo shipping containers and purpose-built modules for use in construction. We provide
two main products, both of which are used to meet the growing demand for safe and green commercial, industrial and residential
building construction. SG Blocks&trade; are code engineered cargo shipping containers that the Company modifies for use in construction.
Rather than consuming new steel and lumber, SG Blocks&trade; capitalize on the structural engineering and design parameters a
shipping container must meet and repurposes them for use in building. These products offer the construction industry a safer,
greener, faster, longer lasting and more economical alternative to conventional construction methods. The Company also provides
purpose-built modules, which are prefabricated steel modular units created specifically for use in modular construction and which
maintain the interlocking and intermodal functionality of shipping containers. We sell our products primarily to customers in
the multi-family housing, restaurant, military, education industries throughout the United States.</FONT></P>

condition or results of operations could be materially and adversely affected. In that event, the value of our securities could
decline, and you could lose part or all of your investment. The risks and uncertainties we describe are not the only ones facing
us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. In
addition, our past financial performance may not be a reliable indicator of future performance, and historical trends should not

of any dividend preferences of outstanding preferred stock would reduce the amount of funds available for the payment of dividends,
if any, on the common stock. Also, holders of the preferred stock would normally be entitled to receive a preference payment in
the event of any liquidation, dissolution or winding up of the Company before any payment is made to the holders of common stock.
In addition, under certain circumstances, the issuance of preferred stock may render more difficult or tend to discourage a merger,
tender offer or proxy contest, the assumption of control by a holder of a large block of the Company&rsquo;s securities or the
removal of incumbent management. The Board of Directors, without stockholder approval, may issue preferred stock with voting and
conversion rights, which could adversely affect the holders of common stock. As a result of these or other factors, the issuance
of preferred stock could have an adverse impact on the market price of our common stock.</FONT></P>

benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the

rights of holders of preferred stock and other classes of common stock that may be issued may be superior to the rights granted
to the holders of the existing classes of common stock. Further, the ability of the Board of Directors to designate and issue
such designated shares could impede or deter an unsolicited tender offer or takeover proposal regarding the Company and the issuance
of additional shares having preferential rights could adversely affect the voting power and other rights of holders of common
stock. Issuance of preferred stock, which may be accomplished through a public offering or a private placement, may dilute the
voting power of holders of our common stock, such as by issuing preferred stock with superior voting rights, and may render the
removal of current management more difficult, even if such removal may be in the stockholders&rsquo; best interests. Any such
issuance of preferred stock could prevent the holders of common stock from realizing a premium on their shares. See &ldquo;Description

a business combination includes a merger, asset, stock sale or other transaction resulting in a financial benefit to the interested
stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior
to the determination of interested stockholder status, did own 15% or more of a corporation&rsquo;s outstanding voting stock.
We expect the existence of Section 203 to have an anti-takeover effect with respect to transactions our Board of Directors does
not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might
result in a premium over the market price for the shares of common stock held by our stockholders.</FONT></P>

or subordinated obligations and, unless otherwise specified in a prospectus supplement, the debt securities will be our direct,

senior to the debt securities to the extent of the value of the assets securing such debt. As of the date of this prospectus,
we have no debt securities issued and outstanding. The debt securities will be exclusively our obligations and not of our subsidiaries,
and, therefore, the debt securities will be structurally subordinate to the debt and liabilities of our subsidiaries. The prospectus

Any common stock sold pursuant to a prospectus supplement will be listed on the Nasdaq Capital Market. It is possible that one

connection with an offering, the underwriters may purchase and sell securities in the open market. These transactions may include
short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by
the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions
consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while
an offering is in progress. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to
the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased securities sold
by or for the account of that underwriter in stabilizing or short-covering transactions. These activities by the underwriters
may stabilize, maintain or otherwise affect the market price of the securities. As a result, the price of the securities may be
higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued
by the underwriters at any time. Underwriters may engage in over-allotment. If any underwriters create a short position in the
securities in an offering in which they sell more securities than are set forth on the cover page of the applicable prospectus
supplement, the underwriters may reduce that short position by purchasing the securities in the open market.</FONT></P>
