ITEM 1.  SECURITY AND ISSUER.

         This Amendment No. 2 ("Amendment No. 2") to Schedule 13D is filed by
the undersigned to amend and supplement the Schedule 13D, dated December 22,
1999, filed by The Rugby Group PLC (now known as The Rugby Group Limited), a
limited company registered in England and Wales under company number 206971
("Rugby") and the Schedule 13D, dated December 22, 1999, filed by RMC Group
p.l.c., a public limited company organized under the laws of England and Wales
with registered number 249776 ("RMC"), as amended and restated by Amendment No.
1 to the Schedule 13D filed by Rugby and RMC (together, the "Reporting Persons")
on April 26, 2000 ("Amendment No. 1") relating to the Common Stock, par value
$.01 per share (the "Common Stock") of Huttig Building Products, Inc., a
Delaware corporation (the "Issuer"). The principal executive offices of the
Issuer are located at 14500 South Outer Forty Road, Suite 400, Chesterfield, MO
63017.


ITEM 2.  IDENTITY AND BACKGROUND.

General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, by Rugby and by RMC (each, a "Reporting Person" and, together, the
"Reporting Persons"). As described in Item 4 of Amendment No. 1, as a result of
the acquisition of Rugby by RMC, Rugby became a wholly-owned subsidiary of RMC.
Rugby then changed its name from The Rugby Group PLC to The Rugby Group Limited,
as Rugby is no longer a public limited company.

         (b)      The business address of Rugby is RMC House, Coldharbour Lane,
Thorpe, Egham, Surrey, TW20 8TD United Kingdom. The business address of RMC is
RMC House, Coldharbour Lane, Thorpe, Egham, Surrey, TW20 8TD United Kingdom.

ITEM 4.  PURPOSE OF TRANSACTION.

         Item 4 is hereby amended and supplemented by the addition of the
following:

         This Amendment No. 2 is being filed as a result of a letter agreement
dated August 20, 2001 (the "Letter Agreement") between the Issuer and Rugby,
pursuant to which Rugby agreed to sell 790,484 shares of Common Stock (the
"Shares") to the Issuer as part of the Issuer's stock repurchase program ("Stock
Repurchase Program"), at a price of $5.99 per share, which was the closing price
of the Issuer's Common Stock on the New York Stock Exchange on that date. The
aggregate consideration for the Shares to be paid to Rugby by the Issuer
represents Rugby's PRO RATA portion of the aggregate dollar amount of the Stock
Repurchase Program, all as more fully described in Item 6 below. The closing of
the transaction contemplated by the Letter Agreement (the "Closing") is expected
to occur on or about August 28, 2001, and is subject only to payment of the
purchase price for the Shares and delivery of the Shares at the Closing.


ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         Item 5 is hereby amended and restated in its entirety:

         (a)      As of the Closing, Rugby may be deemed to beneficially own
5,755,940 shares of the Stock, which based on calculations made in accordance
with Rule 13d-3 promulgated under the Exchange Act and, to the best of the
Reporting Persons' knowledge, there being 19,947,891 (2) shares of Common Stock
outstanding at such time, represents 28.9% of the issued and outstanding shares
of the Common Stock of the Issuer. As of the Closing, RMC may be deemed to
beneficially own 5,755,940 shares of the Stock, which based on calculations made
in accordance with Rule 13d-3 promulgated under the Exchange Act and there being
19,947,891 (2) shares of Common Stock outstanding at such time, represents 28.9%
of the issued and outstanding shares of the Common Stock of the Issuer. None of
the executive officers and directors of either of the Reporting Persons
beneficially owns any Common Stock.

         (b)      As of the Closing, Rugby may be deemed to beneficially own
5,755,940 shares of Common Stock with shared voting power and may be deemed to
beneficially own 5,755,940 shares of Common Stock with shared dispositive power.
As of the Closing, RMC may be deemed to beneficially own 5,755,940 shares of
Common Stock with shared voting power and may be deemed to beneficially own
5,755,940 shares of Common Stock with shared dispositive power. By virtue of
RMC's 100% ownership of Rugby, Rugby and RMC may be deemed to share voting and
dispositive power over the Common Stock.

------------------------
2    Reflects the number of shares of Common Stock outstanding as of June 30,
     2001, as reported by the Issuer in its Quarterly Report on Form 10-Q for
     the quarter ended June 30, 2001, less the Shares to be repurchased by the
     Issuer from Rugby.



                                                                               9

         (c)      Except as described in this Amendment No. 2, neither of the
Reporting Persons has effected any transaction in shares of the Common Stock
during the past 60 days.

         (d)      No person other than the Reporting Persons is known to have
the right to receive or the power to direct the receipt of dividends from, or
the proceeds from the sale of, the Common Stock.

         (e)      Not Applicable.


ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

         On August 20, 2001, the Issuer's Board of Directors (the "Board")
authorized the Stock Repurchase Program pursuant to which the Issuer is
authorized to purchase up to an aggregate of $15 million of currently issued and
outstanding Common Stock. On August 20, 2001, pursuant to the Letter Agreement
between the Issuer and Rugby, Rugby agreed to sell the Shares to the Issuer as
part of the Issuer's Stock Repurchase Program at a price of $5.99 per share,
which was the closing price of the Issuer's Common Stock on the New York Stock
Exchange on that date. The aggregate consideration for the Shares to be paid to
Rugby by the Issuer represents Rugby's PRO RATA portion of the aggregate dollar
amount of the Stock Repurchase Program. The Closing is expected to occur on or
about August 28, 2001, and is subject only to payment of the purchase price for
the Shares and delivery of the Shares at the Closing.

         As previously described in Amendment No. 1, pursuant to the
Registration Rights Agreement, dated December 16, 1999, between Rugby and the
Issuer (the "Registration Rights Agreement"), Rugby is entitled to designate for
nomination to the Board three directors, two directors and one director so long
as Rugby and its affiliates hold in the aggregate 30%, 20% and 10%,
respectively, of the then outstanding Common Stock. Pursuant to the Letter
Agreement, Rugby and the Issuer agreed that, if solely as a result of the sale
of the Shares, shares of Common Stock beneficially owned by Rugby and its
affiliates in the aggregate at any time would constitute less than 30% of the
Issuer's outstanding stock (such new ownership percentage, as it may increase
from time to time as a result of the Issuer's repurchase of Common Stock
pursuant to the Stock Repurchase Program, the "New Percentage"), the
Registration Rights Agreement would be deemed to be amended so that Rugby would
maintain its right to designate for nomination three directors to be elected to
the Board, so long as the Common Stock held by Rugby and its affiliates in the
aggregate constitutes at least the New Percentage of the then outstanding Common
Stock.

         The foregoing summary of the Letter Agreement is not intended to be
complete and is qualified in its entirety by reference to Exhibit 1 which is
attached hereto and incorporated herein by reference.

         Issuer, dated August 20, 2001.

belief, I certify that the information set forth in this statement is true,
