Lennar Corporation
700 Northwest 107th Avenue
Miami, Florida  33172

Dear Sirs:

            We have acted as counsel to Lennar Corporation ("Lennar") in
connection with a registration statement under the Securities Act of 1933, as
amended (the "Registration Statement") relating to possible offerings from time
to time by Lennar of (i) its common stock, par value $.10 per share ("Common
Stock"), (ii) its preferred stock, par value $10 per share ("Preferred Stock"),
(iii) its depositary shares representing shares of Preferred Stock ("Depositary
Shares"), (iv) its debt securities (which may be issued in one or more series)
to be issued under an Indenture (the "Indenture") dated as of December 31, 1997
between the Company and The First National Bank of Chicago and supplemental
indentures executed as contemplated by the Indenture ("Debt Securities") and (v)
warrants entitling the holders to purchase Common Stock, Preferred Stock,
Depositary Shares or Debt Securities ("Warrants") (collectively, the Common
Stock, Preferred Stock, Depositary Shares, Debt Securities and Warrants are the
"Securities") at initial offering prices which will not exceed in total
$500,000,000.

            Based on the foregoing, and such other examination of law and fact
as we have deemed necessary, we are of the opinion that:

            1. When the Board of Directors of Lennar authorizes the issuance of
authorized but unissued Common Stock and in accordance with that authorization
that Common Stock (i) is sold for at least its par value as contemplated in the
Registration Statement, or (ii) is issued on exercise of a right to convert Debt
Securities or Preferred Stock, or on exercise of Warrants, which are sold for
more than the par value of the Common Stock (including any amount paid at the
time of conversion or exercise) as contemplated in the Registration Statement,
the Common Stock will be legally issued, fully paid and non-assessable.

            2. When the Board of Directors of Lennar authorizes the creation and
sale of one or more series of Preferred Stock in accordance with the provisions
of Lennar's Certificate of Incorporation relating to the issuance of Preferred
Stock and in accordance with that authorization that Preferred Stock is (i) sold
for at least its par value as contemplated in the Registration Statement or (ii)
issued on conversion of Debt Securities or other series of Preferred Stock, or
on exercise of Warrants, which are sold for more than the par value of the
Preferred Stock (including any amount paid at the time of conversion or
exercise) as contemplated in the Registration Statement, that Preferred Stock
will be legally issued, fully paid and non-assessable.

            3. When the Board of Directors of Lennar authorizes the creation and
sale of Depositary Shares representing interests in shares of particular series
of Preferred Stock and in accordance with that authorization those Depositary
Shares are (i) sold for at least the par value of the Preferred Stock as
contemplated in the Registration Statement or (ii) issued on conversion of Debt

Securities or other series of Preferred Stock, or exercise of Warrants, which
are sold for more than the par value of the Preferred Stock (including any
amount paid at the time of conversion or exercise) as contemplated by the
Registration Statement, those Depositary Shares will be legally issued, fully
paid and non-assessable.

            4. When the Board of Directors of Lennar authorizes the creation of
one or more series of Debt Securities and in accordance with that authorization
and with the Indenture those Debt Securities are (i) sold as contemplated in the
Registration Statement or (ii) sold upon exercise of Warrants which are issued
as contemplated in the Registration Statement, if the interest on those Debt
Securities is not at a rate which violates applicable law, those Debt Securities
will constitute valid and legally binding obligations of Lennar.

            5. When the Board of Directors of Lennar authorizes the issuance of
Warrants which provide for the issuance of Securities upon payment of
consideration equal at least to the par value of the Securities being issued, if
applicable, and which do not contain provisions which violate applicable law,
and in accordance with that authorization those Warrants are issued as
contemplated in the Registration Statement, those Warrants will constitute valid
and legally binding obligations of Lennar.

            We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the prospectus which is a part of the Registration Statement.

                                                          Very truly yours,


                                                          /s/ Rogers & Wells LLP
