This is a newly revised portfolio of projects, including residential work, libraries, and other commercial projects. Some of the projects were carried out when I was employed at other firms, but all of these are projects where I had a major role in the design and construction of the building. Almost all of the photography is my work, as well.

Some of these projects haven’t been posted here or on my website yet, so this is a chance to for me to share this work some more. Updating the website is on the list next, and these (and other) images will be posted there in a more web-friendly format soon.


These are a few architectural photographs from a couple of recent and current projects. (Larger images if you click on them).

The LS Residence porch renovation was to rebuild the front porch of a Civil War era farmhouse.

The entablature of the porch (everything between the top of the columns and the roof edge) had been wrapped with aluminum cladding and all of the original detailing had been removed. The wood underneath was beginning to fail, and the (once we had it more completely opened up, it turned out to be structurally very different from what we expected).

The two center round columns were still in remarkably good condition and only needed to be scraped and repainted. However, the outside square columns at the corners were both beginning to show signs of damage and rot, and were both replaced.

The new entablature detailing was not necessarily historically accurate, but is probably closer to what it originally had than the blank aluminum that had been there for the past few decades.

It’s not an attempt to be historically accurate, but rather to rhyme with what had been there before (and also to coordinate with the door pediment.

Paint marks (and lack thereof) on the original boards underneath the aluminum and the existing pediment over the door suggested that a dentil band had been the original detail. Dentils in the original door pediment were apparently actual individual wooden pegs. One that detached during the scraping prior to repainting was temporarily replaced with a gold crown.

The JK Residence is an addition to an existing home which is currently under construction. These are a couple of progress photographs.

4 printers in series I saw this article on BoingBoing about a book being produced by using four printers linked together, and I had a flashback to a project of mine almost 20 years ago. The project in the article used stencil duplicator, spirit duplicator, laser printer, and inkjet printer each printing a single color to produce full-color output. And the idea of combining technologies in an ahistoric fashion was what I was interested in with my project, as well.

I took some printmaking classes while I was an undergraduate, but I never did anything with lithography. So, although I was an MFA graduate, I took an evening class at the Toledo Museum of Art to learn lithography. I did a couple pieces with drawing and working on stones, but I also did some photolithography. At the time, I had an Amiga computer which I was using to do some image construction and manipulation. For this project, I created a digital collage and, since I didn’t own a printer myself, I had to take it to an Amiga store and print out the image as a set of 4 color-separated pages. Then, I took those dot-matrix pages to a copy store and had them copied onto transparency material. With those transparencies, I burned a set of photolithographic plates. At last, I printed the four plates in succession with their appropriate colors (magenta, cyan, yellow, and black) in order to produce a kind of four color final image.

The final images from this installation were fuzzy and imperfectly registered, like my own prints. Mostly though, I’m intrigued to find someone else doing a similar kind of project and playing with different levels of technology in an unusual way.

The variety of vehicles in competition for the $10 million Progressive Insurance Automotive X Prize is amazing. There are 21 teams still in competition, spread across three categories. But rather than converging on one particular general design style, as the solar car competitions have tended to do, the X Prize competitors vary hugely. Some, including the amp’d Sky and American HyPower Prius, are essentially just modified conventional vehicles. Others are completely custom built. A number of the Alternative division vehicles are more unusual looking, including three wheeled vehicles fielded by Future Vehicle Technologies and Zap Electric. Alternative tandem class vehicles also include the enclosed motorcycle by Monotracer and the extremely narrow (39″ wide) Commuter Cars’ Tango.

Most teams have only a single vehicle in the competition, but one team, Edison2, has vehicles entered in all three classifications. And while most of the teams still in competition are comprised of teams of professional engineers, there is also the West Philly Hybrid X Team which includes students from an after school program of the Academy of Automotive and Mechanical Engineering based in West Philadelphia High School, a public high school serving one of the most disadvantaged neighborhoods in the city of Philadelphia.

The testing was delayed for a couple hours as a thunderstorm swept across southest Michigan, but vehicles were on the track later in the afternoon. Groups of six vehicles at a time were on the track while EcoGeek was there, and we have pictures of many of the different vehicles after the cut. (more…)


Bathouse on south facing gable of house

We finally put up the bathouse we built a few years ago.  Hopefully, a family of bats will discover it and take up residence, and take advantage of the bounty of insects we have available for them.

To install it, I ended up buying a bent metal joist hanger and cutting it so I ended up with two angle pieces I could nail into the sides of the bathouse, and then used a large nail hole on each piece to set it on two nails in the trim.

I didn’t design the bathouse itself; the plans came from Bat Conservation International (currently located here [PDF]), and I wrote an article about constructing this back in 2007 for Green Options (which is now archived among the articles).  The one modification I came up with was to use some metal drip edge material as a metal roof for the bathouse.  I cut a length of it and nailed it on with a couple roofing nails.  It ought to be more than adequate for the bats.

According to BCI, “Bat houses can be installed at any time of the year, but they are more likely to be used during their first summer if installed before the bats return in spring.”  I don’t know if we got this up in time, but it’s got good orientation,

The original article text is included below the cut, if you want to read the whole thing.

Here’s what I see in front of me at my desk in the ‘Lair,’ my basement office.  Things have been neater: I’ve been shifting through some stuff.  But it’s been messier down here, as well.  Obviously there’s enough room for my laptop to sit on the desk (at least, right now).

I’m contemplating getting a paid Flickr account for my photography work.  Not that this is any work of great art; just thinking about the current image capacity I have with this account.
