My theory is that it resulted from wearing them under ski goggles on a very cold day on the slopes in Utah and then quickly removing the goggles, causing a rapid temperature change in the plastic lens. I believe it’s possible that the relative difference in thermal expansion between a coating on the lens and the lens itself causes the coating to develop micro cracks across the surface. Whatever the reason, I ended up with glasses that I could barely see through. I have quite poor eyesight, so really need my glasses for pretty much everything. What to do?
My first attempt at correction was to go into the Warby Parker store and ask if they could polish my lenses. (I assumed this was a standard procedure. It’s not.) The store said they would replace the lenses under warranty if less than a year old. (Mine were three years old.) They said they’d replace the lenses at modest cost (maybe $50?) but that this would take a couple of weeks. I was traveling, couldn’t do without the glasses and didn’t have a spare pair. I was then planning to order a new pair, but needed a new eye exam, etc. etc.

So, I decided I needed to take matters into my own hands. Youtube andno real help. (Thus, this post; hoping it’s helpful to others.) The first thing I tried was polishing the lenses with a slurry of water and toothpaste, just using my index finger. This sort-of worked…at least giving me an area in the center of the lens I could sort of see out of. I discovered, however, that there are at least two different coatings on the lens and it’s not easy to remove both with an index finger and toothpaste.

Here’s what finally worked. I bought from Amazon a cordless dremel tool, some felt polishing heads, and cerium dioxide polishing compound. You can see the items in the photo. I then used a slurry of water and the polishing compound with the Dremel tool to polish the lenses. It takes 10 minutes or so and you must be very careful to keep everything wet so the lens doesn’t overheat and melt. But, the result is really good. I can see again. You can see in the second photo the edge of the lens and the transition from the region where the coating has been removed and the still-coated area. (I am going to get new glasses, so didn’t get too persnickety about removing every bit of coating.)
I finally had a few minutes to sort my actual construction expenses and put them in some reasonable categories. This is a brief summary of the construction costs.

First, the basic parameters of the house:

    4348 sq-ft of space, including the garage
    3-level “walk-out” design
    2092 sq-ft footprint
    4 bedrooms
    Cathedral ceilings in upper levels
    5 bathrooms
    Enclosed deck on upper level
    Front and rear paver terraces

The total construction costs were $619,000. This is every dime I spent from the time we applied for a permit to the time we received the certificate of occupancy. It does not include the design fees (architect + structural engineer), which were about $60,000. It also does not include the cost of about 15 trips from Philadelphia to Utah, which cost about $10,000.

The cost comes out to $142/sq-ft of enclosed space. The square footage includes the garage but does not include the enclosed deck off the master bedroom, nor the covered terrace. I believe the calculation should include the garage, because the garage basically has the identical finishes as the rest of the house (same concrete, framing, drywall, paint, windows, casing, electrical, etc.).

In many ways calculating by the square foot is misleading. So, I’m providing a lot of detail on the costs by category in the following PDF file. This breaks down the costs by item with the usual “units” that are used to calculate the costs. For instance, the counter tops cost $7489 and comprised 135 sq-ft for a cost of $55/sq-ft.

If I had been on site full time and done all the GC work myself, I might have saved another $40k, which is what I paid my friend to coordinate the job.

I believe that if I had hired a conventional general contractor for this job, it would have cost quite a bit more, but I don’t know how much more for sure. My guess is that the bids would have come in at around $750k and that the change orders would have pushed the total cost to $800k.

My original budget was $550k. I expected to spend at least $50k more, because that’s what happens…and that is basically what happened.

The “just in case” and “nice to have”  items I added (mostly during the design phase) and which pushed up the cost were:

    Snow bars above hot tub .
    Cool-vent ventilated roofing panels 
    Ice shield on the entire roof     Heat recovery ventilator instead of normal bath fans.
    Spray foam insulation.
    Granite or quartz on all counter surfaces and vanities
    Handmade backsplash tile $1000
    CVG fir doors (instead of a less expensive species)
    Programmable “landlord” thermostats in 9 heating zones
    5/8″ drywall instead of 1/2″ drywall     Ipe decking instead of synthetic wood decking 
Thus, I think if pennies were pinched, this house could have been built for about  less.

The only other way to have fundamentally changed the cost structure of this house would have been to engineer out the steel, which probably would have required manufactured roof trusses instead of the conventional rafter and truss system we used, and some changes to a few walls. We could also have supported the front terrace awning/roof with columns instead of the “store front” tie rods. These actions together might have taken out another $15k.

Still, I’m glad I didn’t pinch the pennies and I’m glad I didn’t do the roof or awning differently. Thek is worth it for what are some of the most distinctive features of the house. All things considered, $142/sq-ft is a screaming deal for a highly custom contemporary home like this.
