Designated a Provincial Historic Resource in 2013, the Taber Courthouse presides over a quiet park just off Taber’s main street. The building’s stately arched entryway speaks to its historic importance as one of Alberta’s first “sub-jurisdiction” courthouses, a system of provincial justice administration introduced at the time.
Built in 1918, Assistant Provincial Architect J.B. Allan developed the courthouse design and noted Provincial Architect Richard P. Blakey subsequently revised it. Blakey’s eclectic mix of Edwardian, Classical Revival and Spanish Colonial Revival elements eventually became an architectural prototype for other courthouses of the period. Examples of Blakey’s work that are still intact include the Blairmore Courthouse in the Crowsnest Pass and the Medicine Hat Courthouse. Both of these buildings are Provincial Historic Resources.
The rehabilitation of the Tipton Investment Company is now complete! Designated a Provincial and Municipal Historic Resource, the building is located within the Old Strathcona Provincial Historic Area along Whyte Avenue in Edmonton. It was constructed in the early days of the 1900s and survives as one of the last wood “boom town” style commercial structures in the district.

The current owners, with the assistance from their consultants, contractors, and provincial and municipal heritage regulators, have successfully preserved the heritage values of the modest single-story structure while expertly incorporating an addition. The rehabilitation not only changes the property to a creative two-story multi-tenant complex, but does so while honouring the wood building as the primary heritage value on the lot. Now that’s how it’s done!

This post was originally published on RETROactive on October 31, 2012. However, since we live in Alberta, this topic is almost ALWAYS relevant – what to do about frosty windows!
With winter coming, some owners of historic places might be witnessing the formation of frost on their single pane wood windows and storms, most notably on the second storey. The reasons for this will vary and subsequently so will the solutions. Generally speaking, a little frost now and again should not harm the window frame but a more persistent formation will saturate the surrounding material and, in the long run, potentially cause significant damage. Should this be the case, ignoring the situation is far from the recommended solution.
So what is one to do? The first step, as with any intervention on a historic place, is to develop an understanding of the problem. What is causing frost to form on the window? The answer: warm moist air comes in contact with the cold glass and condenses, which then freezes on the surface. So how does one mitigate this? Should you let the house freeze so that the interior temperature matches the outside, or should you turn the house into an oven to eliminate any and all moisture in the air? Obviously, neither scenario is plausible.
So what is one to do – replace the windows? Speaking from a heritage conservation perspective, replacing authentic historic windows would be the equivalent to someone shaving their head bald because they found a grey hair. Historic windows have, in my experience, proven themselves to be longer lasting than any modern window and can continue to serve their function with proper care and maintenance, while modern windows wear out and routinely need to be replaced.
As air moisture is the general cause of frosted windows, controlling it would appear to be the most appropriate approach. However, there is more than one way to control moisture during the winter. One can control moisture levels with a dehumidifier, or by preventing it from reaching the cold glass with weather stripping techniques. As well, one could better manage the presence of moisture with exhaust fans and insulation. Any combination of these efforts will help to reduce the frost on windows but it should also be noted that there are pre-existing systems that should be taken advantage of in regards to this problem.
Storm windows traditionally have three holes at their bases with a flap cover. During the winter, these should be open to let moisture and condensation escape. When bugs arrive with spring, close the flap. Double hung windows generally have locks where the sashes meet – use them to tighten the window and reduce air leakage. Should you decide to proceed with a form of weather stripping, concentrate on the interior side of the window and allow the storm window to breathe. This will create a micro-climate (similar to the ventilation in one’s roof), which should help prevent frost and therefore better sustain and protect the window.
Hopefully, the preceding information will be useful for those who might be dealing with frosty windows. There are many articles on the Internet, which tackle this issue and propose similar, different and additional solutions ranging from “free to expensive”. As a Heritage Conservation Adviser, my advice, and that of the Standards and Guidelines for the Conservation of Historic Places in Canada, is to start with the minimal approach. With any luck, that is all that will be needed.

This recently completed scope involved foundation upgrades and stair revisions to the ground level access points of the building, including the addition of a compatible, distinguishable and subordinately designed barrier-free access ramp, as well as masonry repairs and the replacement of the 1980’s metal storms with more historically appropriate wooden units that will have the added benefit of allowing more natural ventilation in the building. Additional work also included the rehabilitation of the former fire exit door openings, the return of the round window at the top level of the building and the addition of vented caps to the non-functional chimneys.
