Union Station Train Shed Renewal



The interior of the Union Station Train Shed, shortly after opening.

Completed in 1930, the Union Station Train Shed was designed by Toronto Terminals Railway Assistant Bridge Engineer A.R. Ketterson. The design was a variation on the Bush train shed, invented by American Engineer Lincoln Bush in 1904. Bush sheds replaced the expensive and difficult to maintain, large balloon-framed train sheds that were common in 19th century Europe. Linear smoke ducts directly above the tracks would permit the evacuation of smoke from locomotives while protecting passenger platforms from the elements. Other Bush sheds include: Chicago Union station 1925, Hoboken NJ 1906, Winnipeg 1911, and Montreal Windsor Station.

ERA, as Heritage Consultant, is responsible for the conservation of the Train Shed as part of Union Station Train Shed Rehabilitation. The Train Shed Rehabilitation is a major part of the 10-year program of repair, restoration and upgrading of the Metrolinx facility and railway corridor.

The Train Shed is designated a National Historic Site and is subject to a heritage easement agreement between Parks Canada and Go Transit. The project includes the construction of a new central atrium (designed by Zeidler Partnership Architects), the restoration of the shed over Tracks 1 and 2, and the rehabilitation of the remainder of the shed. Construction is to begin shortly, and is set to last 5 years.

Together with the Union Station Revitalization project initiated by the City of Toronto, the changes forthcoming at Union Station will greatly improve the efficiency and user experience of the station. For more information, please see the official Union Station Renewal site.

The Holiday Spirit

ERA celebrated the season with an insiders tour of the Distillery District (an active project in the office since 1995), and an obligatory stop at the Mill St Brewery, followed by a wonderful dinner party at the (perfectly historic) Campbell House.

Thanks go to curator Liz Driver and planner David Vallee, our gracious hosts; it was a great way to kick off the holiday season!

PS: It was all a highly dignified affair up until a certain hour, after which, it devolved (as it always must).  The 2am tequila was not really necessary.

Whatever happens after midnight demands to remain anonymous.

Jerome Markson: Houses and Housing 1955-1980

Legendary architect Jerome Markson came in and gave a presentation on the residential projects produced over the first third of his career – from 1955 up until 1980.

He showcased a number of experimental single family housing designs, and his transition to multi-family and social housing projects. Alexandra Park featured heavily, and we were all eager to learn more about the lessons contained in the project that can be applied to our understanding of our collective urban environment.

1959 _ Winston Avenue Residence


1960 _ Saintfield Residence


1962 _ Montressor Drive Residence


1965 _ Alexandra Park Public Housing


1968 _ Folkstone Crescent Stacked Housing


1971 _ Unionville Stacked Housing

In Mr. Markson’s own words, from 1981:

In all of our work we constantly attempt to produce a solution which respects a site, street or ambiance worth respecting, to reflect a client’s needs with warmth and humanness and to recognize that no single solution or architectural approach handles all problems. While striving for innovative design and the use of appropriate construction techniques and materials, we keep an open attitude necessary for creative solutions.

We are very grateful to Mr. Markson for sharing his time and insights with us, and look forward to part two…

Don Valley Brick Works

Wednesday morning’s design forum took a slightly different approach this week. The ERA team went on a field trip down to the Don Valley Brick Works, a site ERA has been working on since 2002, to meet up with the George Brown Masonry students. ERA has been performing site review to the masonry students who are in the second year of their Building Restoration Technician Program.

Professor John Jensen, an experienced heritage mason, provided us with a hands-on demonstration of various types of mortar batching including: lime putty and sand; hydrated lime, sand and water; and a pre-bagged Dubois mix which has hydraulic lime. Each mortar has it’s own unique characteristics, and we were able to explore each in turn. Once we had the mortar batched, everyone took a turn at pointing a mock-up wall.

The hands-on experience gave everyone a taste at the work involved in providing specific pointing profiles and techniques, as well a better understanding of the tools, techniques and craft of fine masonry.

Window and door openings

This past Friday Scott gave an internal presentation about the different types of window and door openings in masonry construction, how to write about and describe each element correctly, and how these elements can help to locate a building within a specific historical period.

The presentation also included a brief tour of some architectural wonders in his hometown of Detroit, MI – many of which are currently for sale at rock-bottom prices.



More images from Scott’s extensive catalogue of architectural photographs are available on his Flickr page.

North York’s Modernist Architecture Forum

ERA Architects is helping out with an upcoming forum on North York’s modernist architecture that is taking place this Tuesday evening at the North York Civic Centre.  The forum focuses on raising awareness for modernist buildings and landscapes in the city.  The event includes a panel discussion consisting of Dave LeBlanc (Globe & Mail), Leo deSorcy (City of Toronto Planning Division), Kim Storey (Brown and Storey Architects) and Lloyd Alter (Architectural Conservancy of Ontario).  The discussion will be moderated by Matt Blackett of Spacing Magazine.

We will be contributing to the event by printing an update to the document, North York’s Modernist Architecture, put together by the City of North York in 1997.  The original document was developed to underline the importance of modernist buildings, and many that were featured found their way onto the City’s Inventory of Heritage Properties.  The updated document – available exclusively at the forum – will include the original in addition to new essays by the featured panelists and current photographs of a number of these buildings.

Historic Modern

Modern buildings are funny things. Their proliferation has been accepted as the common typology for city forms, yet they are often perceived as a banal insertion to the city’s skyline and an impediment towards a richer public realm.

Following a recent talk at Heritage Canada’s annual conference on the adaptability of modern buildings, I was asked about the possibility (if any) of “fixing” the maligned relationship between these buildings and the public realm. I perceived this question as one that considered this association over with little chance of reconciliation.

Modernism’s indifference does not sit well with many, and it was evident that an optimistic approach on its structures’ adaptability would not be accepted with immediate enthusiasm.

In their book Collage City, Colin Rowe and Fred Koetter critiqued the city of modern architecture against the built conditions of the traditional city. With the adeptness of the ‘bricoler’, Rowe and Koetter state that these early city builders had the ingenuity to maneuver within and around the city’s built forms and spaces in order to complement and integrate with their surroundings. Referring to existing conditions became a moot point in the Modernists’ agenda and was largely disregarded for an opportunity to begin anew.

With some irony, it is this disregard that opportunistically positions the current generation of city builders. Presented with these latent resources, the buildings and landscapes of the recent past are now prime for reconsideration.

As they move well beyond the years of their life expectancy, the bricolers for this generation need to rethink, react to, interrogate, exploit, and most important, understand these buildings and landscapes in order to reconsider their initial ideals and to fully explore these inherited opportunities.

Artscape Wychwood Barns


Wychwood Barns under (re)construction


Grand opening weekend

A collection of street car barns constructed between 1913-21, the Wychwood Barns are the oldest surviving carhouses built as part of the Toronto Civic Railway, a transportation system with a significant role in the development of the annexed areas in the City of Toronto. When completed, the facility accommodated 50 cars inside and another 110 outside, with access to the yard via nine tracks.

ERA was the heritage consultant for this project, and was involved from the Building Permit application through to project completion. Services included providing a Conservation Plan, preparing working drawings for the alterations to the Barns, and helping to complete the Heritage Easement Agreement. Additionally, ERA worked with Gottschalk+Ash International on wayfinding and site interpretation, and with David Leinster and the Planning Partnership to convert the remaining land on the site into a new public park.

Can’t order those from a catalogue..

The interior of the Carlu is the wealth of small, custom details – from the lights to the central fountain to the return-air grilles. The grilles especially are miniature art-deco treasures, and demonstrate an artful way of elevating a necessary ‘building-systems’ component into an element which helps define the atmosphere of the larger space.

A Grand Entrance

John Lyle’s original vision for the north-western entrance to the City of Hamilton.

Reminded me of John Lyle’s plan for Federal Avenue in downtown Toronto, linking City Hall to the north to his Union Station to the south. Civic building on a monumental scale – interesting to imagine how it would have changed both the historic development and the overall character of Toronto.

For more information on John Lyle, Coach House Books has just published a new book on his work titled A Progressive Traditionalist.
