The hugely controversial addition to the historic Château Laurier hotel can go ahead, Ottawa's planning committee voted Thursday.

Several city councillors said they dislike the hotel addition's modernist design, and said their inboxes are full of emails from frustrated residents who also detest it. Nevertheless, the committee approved the site plan by a vote of 8-3.

Larco Investments clears the final big hurdle at <a href="https://twitter.com/hashtag/ottcity?src=hash&ref_src=twsrc%5Etfw">#ottcity</a> for its controversial Chateau Laurier addition. Planning committee approves the site plan in a 8-3 vote. Heritage permit (ie. design) was already approved by council last June. <a href="https://twitter.com/hashtag/ottnews?src=hash&ref_src=twsrc%5Etfw">#ottnews</a> <a href="https://twitter.com/hashtag/ottcity?src=hash&ref_src=twsrc%5Etfw">#ottcity</a> <a href="https://twitter.com/hashtag/cdnpoli?src=hash&ref_src=twsrc%5Etfw">#cdnpoli</a> <a href="https://t.co/oa4D7mPshb">pic.twitter.com/oa4D7mPshb</a> —@KatePorterCBC

"It is their property, no matter how much you dislike [the design]," said Coun. Rick Chiarelli, who questioned why the National Capital Commission, Parks Canada or other federal agencies hadn't stepped in.

The design has been modified five times in the three years since it was first proposed, and has been reduced in height from 11 storeys to seven.

City council had already approved the more critical heritage permit last June. At the time, council told the architect to include more limestone and better reflect the shape of the existing Château Laurier's windows. The city's chief planner, Steve Willis, has said those conditions have been met.

On Wednesday, Coun. Mathieu Fleury tried to convince city council to revisit the heritage permit, but council refused. Fleury said he'll try again in the coming weeks.

A close one, but the motion is not allowed -in a vote of 10 yeas to 12 nays. In case anyone's wondering how the Chateau Laurier vote will go at planning tomorrow, this should give a strong indication, I would think. <a href="https://twitter.com/hashtag/ottnews?src=hash&ref_src=twsrc%5Etfw">#ottnews</a> —@jchianello

Ottawa's head planning lawyer, Tim Marc, said going down that road would land the city in court with Larco.

With its site plan now approved, all that's left for owner Larco Investments to do is to obtain a couple of minor approvals from the NCC and the city's committee of adjustment.

Despite a chorus of opposition from residents, Ottawa's planning committee approved the proposed addition to the Château Laurier in an 8-3 vote. 1:38

Addition a 'desecration'

Speakers at Thursday's meeting didn't mince words.

Former cabinet minister David Collenette called the addition a "desecration" and a "travesty which vandalizes a national historic site."

The Château is fire. The addition is water. The two are locked in a struggle to cancel each other out. - Peter Coffman, architectural historian

Architectural historian Peter Coffman said the design is completely incompatible with the historic hotel.

"In place of romance and playfulness, we have straight lines, right angles and mathematical precision. The Château is fire. The addition is water. The two are locked in a struggle to cancel each other out," said Coffman, who also called the design "grotesque."

Shawn Barber of the Centretown Citizens Community Association said the public intuitively understands that disconnect, too.

"Listen to the radio call-in shows, look at social media, read letters to the editor," he said. "Rarely will you find the public so united on an issue as opposition to this proposal."

The architects for Larco Investments called the addition an essential project that needs to move ahead so the hotel can compete with others in the city.
