Stratton House Progress Report for January 2013

I visited the Stratton Project the other day to see how things were progressing. Flooring is going down (locally milled white oak) and plaster is going up. I'm very happy about the decision to plaster the walls on the main floor. The whole house inside and out is turning out to be a very tactile thing. The (experimental) rough hemlock siding on the exterior will weather to a soft grey and has the appearance of fabric, the plaster has just enough texture to do wonderful things with light in a way that a painted wall simply can't and the raw steel structural beams and posts provide a beautiful space defining element. The steel siding is actually "midnight bronze" which means it has a lot of color depth and can appear black in low light and shadow but really bursts forth in bright sunlight with the bronze undertone. Houzz.com has a lively discussion of black houses going on right now and lots of very strong opinions are being expressed! I have always loved black and dark houses. The more monochromatic the better. It speaks to the kid in me - I expect something more exiting from a dark house in a monsters under the stairs and witches in the attic way. With a modern looking project like this it's always interesting to see what the folks who work on it say. Some are completely sold and others not so much.

I completed Passive House Designer training after the design of this house and with my new level of knowledge of super-energy efficient construction, I would have done a few things differently perhaps but not much. At some point I will complete energy modeling on this project to see how close to the passive house standard we go.

Over the next few months the interior should be completed and I will post photos as things progress. The outside will look good for a while, then the snow will melt and it will look crappy until site work is completed.

Miscellaneous Musings

I am working on this new small greek revival in Maine. Not the high style Greek Revival with huge columns like you see on banks and government buildings but the small, simple style that is so ubiquitous in New England and doesn't get much attention but everybody knows. I'm designing it to "pretty good house" standards. It is for a family member who lost her house in a fire- we'll see how the budget goes and if the details get watered down as is often the case. She has always loved the Greek Revival look which is more often done wrong than right it seems. I used this sketchup model to push and pull and play with trim and proportion to get it right. I have found that often the frieze board (the wide flat board at the top of the siding under the eaves) often gets shortchanged when the builder frames the house including window openings then discovers that he doesn't have enough room for a properly proportioned frieze.

In any design there is always a lot of back and forth on windows - what works inside may not be so great on the outside etc. so I use the model to really fine tune it in terms of balance, rhythm, symmetry/asymmetry (exterior aesthetics) and light, cross ventilation, views, sun and solar gain, the feel of the room, (function and interior aesthetics)

This is very different from this house which is currently under construction in Vermont which is also a "Pretty Good House" although nearly to the Passive House with Unilux triple glazed windows from Germany But with a modern aesthetic and some really beautiful spaces and materials. We are using raw green 1 x 3 hemlock from a local mill at siding over coravent strapping (rain screen detail) and Mento 1000 weather barrier. The hemlock will dry in place, turn grey and gap in a rougher version of open joint siding often created with Ipe or cedar siding.

I am also studying and reviewing the first three days of Passive House training. The next three days are coming up next week. I am learning a lot of building science stuff that will improve the level of design and service I am able to provide - whether or not I ever get to work on a certified passive house. It was disconcerting, however, to ride the bus into Boston past thousands upon thousands of older houses and housing stock that is rather the opposite of Passive House in terms of energy usage and all the other metrics. You get the feeling of "what's the point". Is passive house a just another trophy for someone building a new house to attain and meaningless in terms of saving ourselves from the coming death, doom and destruction of climate change? I am looking at it in terms of simply building better houses and not thinking about saving the world.

Green Hemlock Siding on a Modernist house in Vermont

Construction is underway on this super insulated modern house in Vermont where we are trying out some very cool things.

Siding for instance. The lower siding is 1x3 green hemlock, unfinished from a local mill over insect screen over coravent strapping over Solitex mento 1000 building wrap from 475 supply over Vantem Sips..

The Solitex is a beautiful product, black and with UV protection which allows for an open gap siding treatment. I spec'd 1x3 local green hemlock because it is beautiful to work with when green, will shrink and gap in place as it dries and turn gray, The individual pieces are somewhat irregular so the overall effect is like a fabric. Very sexy and at a fraction of the cost of some other wood sidings. Hemlock is a very durable wood when left to weather. When I was a teenager working in a sawmill in Maine we cut a lot of hemlock to build a bridge over the crooked river. I also used it for much of the framing for my barn and I have many staging planks of hemlock. Because it is untreated all waste can be burned as kindling, or even tossed into the bushes to provide habitat for red backed salamanders. The photos show the window holes boarded up in preparation for the coming storm. I was there the day the glorious windows from Unilux were delivered. Next up: installing the windows - a very different affair than the standard American window with flanges.

Chris Corson, a builder in Maine working in the Passive House arena used raw pine in a similar fashion on this neat little project

Note to Do-it-yourselfers

The following is from a note I just sent off in an email and I thought it might be appropriate for the blog. In terms of budget and simplicity which go hand in hand I recommend one of two methods. If you have time and some good solid professional framing experience I recommend double wall stud frame construction. Otherwise I recommend a SIP shell. SIP's start to get expensive when you add a real timber frame and lots of jigs and jogs and dormers. Another consideration is to minimize working on a ladder, especially on an uneven site. Ladder/staging work adds time and $$ (and danger). So either keep roof work super simple and easily hired out or keep the roof low or wrap a porch roof around that you can use as staging to work on the roof. A simple rectangle with a double pitched roof can be made amazingly elegant and fun through detailing, proportion and windows. The SIP shell kills several birds with one stone (must think of better analogy) but I have seen some very messy SIP craftsman ship by big players in the SIP industry so you have to be careful. Mismatched joints that telescope through the shingles on the roof or make it difficult to sheetrock over are common as are un-foamed gaps where you can see light through. So careful oversight is important. With a Structural SIP shell you can get fancy with local hemlock lumber to support and upstairs which can have a very warm industrial/agricultural/modern look to it. I often seem to do houses for do-it-yourselfers and there is definitely some good inexpensive forgiving detailing that can be used. Above all, use methods of construction and detailing that are common and easily understood as well as hard to screw up.

Perry Road Porches

I have started working on the Perry Road porches. Freezing my butt off and that sort of thing. But it is fun to do a bit of carpentry again. I will post pics here as things progress.- - - - - - This is yesterdays (1-4) photo. I spent today finishing up details before metal roofing goes on. The whole thing is solid and straight. One of the things I like about carpentry is the problem solving aspect. I like to figure out the whole enough to know I won't get into trouble on a detail later on. There is an aspect of improvisation to it. When I built my fern house, there were no drawings. I sketched out enough of the whole to understand that the details would be easily solved as I went along - and they were. I suppose this is not very architecty of me but it works out fine. I think this is what separates good carpenters from the rest - the ability to look ahead and work with all levels from the whole to the minute details simultaneously. I have often seen carpenters do what seems easy or logical at the moment only to get boxed into a bad detail resolution later on because of the inability to conceptualize the whole. Much of my detailing as an architect is just enough to guide a builder along a path without them getting boxed in but allowing room for improvisation and improvement. - - We got the roofing on last week in time for the big snowstorm

This is an actual hand rendering of a very large house that I did schematic design for a few years ago. It was to be Timber framed with SIPs (Structural Insulated Panels) I never did construction drawings and it was pre sketchup so there were some museum board models and a Vectorworks 3-D timberframe study. It is always an interesting study to design a large home like this and make it look nice. It requires a completely different mind-set than most of my work and really takes a different perspective.

Gouin Green

I just added a link to Gouin (Go-In) Green a process blog where some folks are building a SIP modular house.  The house is rather vanilla but the blog is full of excellent information and $ #'s which I always appreciate.  It looks like they actually used Alpen Windows which are super good and they talk about how they justified the extra cost.   There is also a long discussion of radiant heat in a super-insulated house in the Features section

Perry Road Project

okay, enough talk, lets see pictures. This is a house that I have just finished tuning and tweaking. Construction will start next month. see my website for more information. We may set up an independant blog for this project. We are going for LEED certification and of course, Energy Star. We are pushing the low cost limits as well. I designed it so that the owners can do most of the labor without getting into too much time and complexity. Materials and subs costs are coming in at a little over $50 per square foot not including site work, well and septic. The shell is made of structural insulated panels from Foard Panel.

Oh, and of course, being in Vermont, there is a sleeping porch.
