A Variety of Tasks

Welcome back to my journal, dear reader! This log aims to provide for you an accurate account of the goings-on of Reverend Walker’s Home. Might my words inform or at the very least entertain, then I should be satisfied with its effect. I generally begin these entries with a current description of Hale County as a whole, to provide a context to place the actions of my crew.

As of late, the county has sunk into a thick, languid humidity that prevents large amounts of evaporation. This atmosphere results in dense fogs, oppressive temperatures, swampy ground, and incredible displays of heat lightning. It is not a forgiving climate, to be sure. But it is a West Alabama climate and it’s in it that the special quality of Hale County is made.

My crew labors through these conditions with spirit and humor. They are a hardy bunch indeed. But enough of my musings, dear reader, you must think me sentimental. I have set the team a multitude of tasks to be completed. These range from procuring materials and making final orders to wiring and plumbing the home.

Interior Framing

putting in the interior walls

To separate program and create a loft space, a small number of interior walls were built. These divide the living and core spaces, and divide the core space into a bathroom and kitchen, with a small closet facing the living area. It was not a big task, but it was a good feeling to be done putting the bones of the home together. After getting the sticks up we put together the loft floor and were ready to sheath.

Sheathing

Reverend Walker’s Home uses an OSB sheathing system wrapped in tar paper. The large sheet material makes it a relatively quick process. It was interesting to experience the space in and around the solid volumes for the first time.

Mechanical, Electrical, Plumbing

Before we can get drywall up, we need to install the guts of the home. This includes running wire for fixtures and plugs, running water lines, drains, and vents. Reverend Walkers Home uses a PEX water supply system. Getting to focus on some nitty-gritty MEP details was a refreshing change from rough carpentry.

Lighting Design

Before we can finish up electrical and get insulating, we need to develop a lighting strategy. To help we used the built volumes as 1:1 mockups, and clamped lights around to draw conclusions. We did this for the interior and porch spaces. Interestingly, our initial idea for lighting the exterior was to use the overhead roof as a lighting device. Instead, we found it far more comfortable to reduce the scale by bringing the light down. This has developed into an overall strategy of letting the spaces be grand and open during the day, and shorter, closer to human scale at night.

Windows

The quest to crank out window units continues. You will recall the custom cypress windows our team have designed. We are eager to complete these and get them in the house so that we can move forward with cladding the home in galvalume r-panel. In total there are five windows of three varieties. The difference being in the proportion of glass to hatch. I walked into the shop for some pictures, this is what I found Addie up to.

Indeed, my crew has been hard at work. I have put my full trust in them to perform their tasks well. Fortunately for me, they are a good lot which makes management easy, leaving more time to nap. As the Reverend’s home nears completion, look forward to learning about siding, lighting, and finish carpentry. Things are going to begin coming together fast. Alas, dear reader, I must draw an end to this journal entry, for I have grown weary. I believe I will choose the Reverend’s slab porch for today’s restful occasion.

Cordially,

Beginning the Enclosure

Rendering of Reverend Walkers Home from the Street
Rev Walkers Home

My my, dear reader, it has been some time hasn’t it? Welcome to my latest journal recounting the design and progress of Reverend Walker’s Home. I can assure you the silence has not been due to any lack of activity, rather the opposite. Upon completion of the large pavilion structure, my crew has moved underneath to begin constructing the enclosed volumes that inhabit the space between slab and roof. You can be sure that they are grateful for the sheltered workspace that defends them from rain and sun. They have no excuse to not be working. Myself, I have found it a most suitable location for napping. There’s much to catch you up on, dear reader, so let’s begin with a recap of the design of the Reverend’s Home.

The Home

Batter board plan

Reverend Walker’s Home is a response to the rural phenomena of home addition, which you can read about in an earlier journal. It aims to provide a forgiving space on a strong foundation to facilitate successful addition. The home is a kit of three parts: a slab, a roof, and two enclosed volumes. One volume is the main living block with all necessary program. The smaller volume is a partially unfinished space furnished with utility stub-outs.

The intentionally disparate items are intended to imply a process of addition… first the slab, second the roof, third the enclosure, and so on and so forth. Although the home encourages clients to design and extend the enclosure according to their lifestyle, it is completely livable as-built. Crew member Paul likens the Reverend’s Home to a “hook to hang one’s hat on”. Ultimately, it is built as a minimal enclosure with a luxury of porch space. The porch could exist as outdoor living, or be infilled.

As of now, the roof and slab are done. The only piece of the kit left is the enclosure.

what’s next?

Slab Seal

As a part of our vapor barrier system, we used a DOT approved slab seal to ensure that moisture can neither seep into the slab or move up through it into the home. Before sealing, the slab was pressure washed and left to dry for 48 hours. This stuff is very hydrophobic and water now squeegees right off.

Mock-up

Before diving into framing the units underneath the roof, we needed to ensure that our details were going to work. We do this by building 1:1 mockups. In ours, we tested framing and flashing details, as well as a full-scale mockup of our custom window design. You might recall that our team has designed a window system made of a fixed glass pane and an operable ventilation hatch. By doing the mock-up we were able to refine details and systems which will make a better final product.

Floor

Satisfied with our details, we’ve moved on. To make things easier in the future, we decided to go ahead and attach our treated sill-plates to the slab and build the sub-floor. We used powder-actuated and pneumatic tools for the plates. The sub-floor is r-7.5 rigid insulation between sleepers with plywood on top. Following the installation of the floor, we were ready to frame.

There you have it, dear reader, the current state of Reverend Walker’s Home. It’s certainly beginning to take shape. With my thoughtful leadership, I have brought us to this point and will continue to ask my crew to go above and beyond. I am confident they will not disappoint me. My next order will be for them to put up sheathing and wrap the house, after which I will banish them to the woodshop to build all the windows and doors. Alas, I could go on forever, dear reader, if only it wasn’t my nap hour. For now, I must retire to the captain’s table and rest my weary paws.

Assembling a Rather Large Roof

Welcome to the blog, dear reader. This journal is my honest recounting of the design and construction of Reverend Walker’s Home. It is late May. Day by day we ease further into the dense atmosphere of the West Alabama summer. The thickness of the air is visible at certain times of day, beautiful and inescapable. This is the time when a big hat is a necessity rather than an accessory. This being the case, my crew has been pushing to raise the great pavilion roof that is the key feature of the Reverend’s home. The roof will provide a solar reprieve through the coming months. It should then please you, dear reader, to learn that a milestone has been made in this endeavor.

Barn Raising

Trusses are up! Thanks to Shane of Stillwater Machine, and our professors Steve and Andrew, we were able to get the six trusses lifted, secured, and braced in a morning. What follows is a summary of the steps my crew took to get to this point, starting from what I described in my last entry.

Brackets Set
start with some brackets
plane ends of post and trim to length
stand it up
level and brace
auger for thru-bolt
secure bolts
fasten screws
repeat

Soon after getting the columns up, the trusses were delivered, and we quickly realized there were a few discrepancies from our specified drawings. The mistakes were fixable so we brought out the angle grinders and got to work trimming steel. Once the revisions were done, the trusses were ready for the boom-truck to lift them into place.

To be perfectly truthful, the process was less smooth than this slideshow implies. There were many obstacles to overcome. But trust when I say, dear reader, that when ill-fated circumstances arrive, my crew does not despair. Due to my fine leadership skills, they rise to the occasion and do what has to be done with their heads held high. With my steady paw on the wheel there is no chance this ship runs aground. I will continue to document the progress of this home in future journals, but for now I see Reggie sitting, and therefore I must also sit. Look forward to accounts of mock-ups, roofing, and window making.

Myself and Reverend Reggie Walker

An Earnest Account of Plumbing & Piping

Hark, dear reader, and hear my tale! In my previous journal, I happily announced the arrival of Spring in Hale County. Indeed, the change in temperature was welcome by friend and feline alike. However, I must admit that the boons of Mother Spring cannot be divorced from her burdens. The tempests of March are frequent, strong, and heavy as to turn stable earth into a muck so thick it will suck the sole off one’s boot. My crew has been battling these conditions in a campaign to prepare our site for an approaching concrete pour. Several tasks must be completed before the slab is laid down, the first being to install plumbing & piping. With a slab-on-grade foundation, all of the infrastructure must be installed prior to pouring concrete, this includes the electrical and water mains, as well as waste drains. Our process for this is as follows:

Student hammers in stake
set batter-boards & strings
students dig plumbing trench
dig and grade trenches
prime and glue
student checking slope of a pipe
check your work
completed plumbing on site
revel in a job well done

Although most of the digging was done by hand, we were able to make use of the trencher during a few particularly dry days. The width and depth of the trench that the machine makes is perfect for laying water and electric mains because it can easily dig beneath the frost line in the area. We are grateful when the weather is nice enough to start the trencher up.

You might be wondering why there is so much plumbing! Reverend Walker’s Home features a main living volume with a kitchen, bathroom, bedroom, and loft. In addition to the main enclosure is a separate room that we have dubbed the “bonus room”. The bonus room is a partially unfinished space that is supplied with plumbing and electrical stub-outs to allow for many possible uses, whether for storage, a home office, a studio, or even another bathroom. The initial investment into infrastructure will enable a homeowner to quickly and easily expand their home.

You will be happy to hear, dear reader, that this step in the process is complete. My next order will be for my crew to set formwork for the slab and column footings! Despite the sky’s grim countenance, spring brings longer days and fresh growth, and morale remains high! The wind is at our backs and I will continue to push this team steadily towards greatness! Alas, dear reader, the magnolia leaves are dripping water onto my head, and I must retire to my chambers for chance I catch a cold.

Reverend Walker’s Home

Hi there! Back for more, are you? Well, if you were intrigued enough to return to this humble little blog of ours, we should probably give you the low down on what Rev. Walker’s home is all about. As mentioned in our last post, our project is a continuation of the research started by the 2019-2020 outreach master’s team, who were interested in taking a pole barn structure and applying it to rural housing, as it is an efficient and easy building technique. This, combined with our own observation of trends in rural homeownership, in particular those of expansion, has led us to explore a starter home, completely separated from, but sheltered by a single-source, kit-of-parts pole barn. What is a pole barn? And why would we separate it from the structure of our home? We’re glad you asked!

Typically, pole barns use large, widely-spaced wooden posts buried straight into the ground to carry trusses supporting a large clear-span roof. What can often be found underneath is a slab on grade or merely a dirt floor. These structures can be seen all over Hale County, usually serving as manufacturing buildings, churches, or simply just for storage. Well, that’s where our challenge comes in, dear reader – to make this building type function well as a home.

components of a pole barn

Because this technique minimizes the use of materials, it can cover swaths of space previously unachievable by past 20K homes for the same price. By having the home begin as an enclosure for a single person or couple, we can dedicate the rest of our resources to providing the largest roof and slab possible, sheltering and providing a sturdy base for future expansion. This is ideal as oftentimes additions compromise the original home’s structure as multiple roof and foundation systems are tied together.

By having the structure of the home completely separated from the pole barn, the owner doesn’t have to learn how to add onto a less conventional post frame home and the overarching roof can remain untouched, maintaining its integrity. The pole barn can then take the brunt of the weather that would typically age a home and can protect new connections if the house grows.

Having two independent structures also preserves the quick and easy nature of the pole barn, allowing all of the components to be purchased off-the-shelf from a manufacturer without having to fuss too much with modifying it to have residential details and tolerances. This is important to us as we want this home to be as accessible to buy and simple to build as possible.

weather cant keep us off site

This ability to put up a roof fast also gives us a dry place under which to work without weather delays or breaks (remember: “healthy body, healthy mind”), as well as covering potential expansions by the owner so there’s no need to rush.

In our scheme, the approximately 500-square-foot home is covered by a 1,900-square-foot, 5-bay pole barn. The difference in size results in a luxury of outdoor space, where at the start it can serve as a large porch – the primary social space in rural communities. The home is broken up into two volumes arranged into a dogtrot scheme – one with all the rooms necessary to make a viable home and the other left blank to be used as the owner sees fit.

This not only starts to define outdoor rooms, but also implies infilling between the volumes as the first move of expansion. Additionally, the monopitch shape of the home’s roof gives clues towards expansion, hinting that one can march the same roof pitch between the volumes and come off the high side of the home to infill the front. This extra initial height in the home also provides opportunities for a loft space, which can serve as storage or a sleeping space and help with ventilation.

If you’ve made it to the end of this long but passionate discourse about our explorations, I commend you. But for now I must leave you, as my four underlings are returning to site with greater frequency to prepare the area for construction, but with an alarming lack of extra scratches. Something must be done about this.
