basic container design – insulation

Since mankind crawled out of the caves and began building shelters for ourselves we’ve been obsessed with maintaining a comfortable interior temperature. This is especially true when working with a steel shipping container…after all, IT’S STEEL! If left in the heat, unprotected, interior temperatures will rise higher than the inside of your car on a hot day – and we all know what it feels like to sit on hot leather seats…OUCH.

So how do we insulate a container, not just to maintain interior comfort but also to ensure that our finished structure will remain safe? (note – heat greatly effects the physical properties of every product used in a home or building) There are various types of insulation we can use based on insulating characteristics and cost. Common types of insulation are:

Batt or Roll Insulation: Most common. Found at any hardware store. It’s “the pink stuff”. About R-3 per inch. Cheap and easily installed. In a typical 2×6 stud wall you’ll get about R-18…at least so the label tells you. You’re really getting less than that because it’s nearly impossible to install perfectly, which means you get all kinds of voids and crimples, etc. that affect the R-Value.

Loose Fill or Blown Insulation: Also found at most hardware stores and is made from shredded blue jeans or paper or cellulose. About R-4 per inch. Also cheap, but requires renting equipment to install and can be difficult to fill stud cavities in existing buildings. It’s great for attics and other large spaces.

Rigid Board Insulation: Typically Polystyrene or Polyisocyanurate (plastic). Comes in sheets that are easily cut to size. About R-4 to R-7 per inch. Sort of cheap and easily installed. Can be cut to size and placed in stud cavity. A typical 2×4 wall will give you up to R-21, but again this is affected by voids and joints in the boards.

Spray Applied Insulation: Either open cell or closed cell. Open cell will absorb moisture, so it should not be used in moist climates. Closed cell creates an air tight barrier and is expensive. Both require skilled installers. Most bang for your buck in terms of performance. About R-4 to R-6 per inch (though some say it can be as much as R-10 or R-12 per inch). When insulating containers, I find it best to insulate one of three ways: exterior, interior or both interior and exterior. In extreme climates, warm or cold, it’s best to insulate both interior and exterior to achieve the maximum R-Value without sacrificing too much square footage while still protecting the container and providing necessary cavity space for electrical and plumbing.

Poured or Injected Insulation: Similar to spray applied. Installation is either through a series of holes cut into existing walls or through the sill plate at the top of the wall. Great for renovations and retrofits. Expensive and requires skilled installers. R-values similar to SPF – about R-6 per inch of thickness.

Radiant Barriers: This is a new technology and has not been well tested over time. You may have seen things like ceramic coatings featured by Bob Vila and others touting their sometimes miraculous benefits. I’m optimistic for the technology, but will reserve final judgement for when the product has been time tested and proven. The basic principle is in the name – it creates a barrier that radiates heat energy away from the surface without allowing it pass to the interior.

Any of these insulating materials are suitable for use in a shipping container home. Remember that the container itself is just a building block, one component of the building envelope, no different than wood or metal studs and sheathing. So just like with any other material, it’s important to figure out your cost/benefit scenario early. Options are wide spread and it is simply finding a balance between what you want your home to look like, how you want it to function and how much money you want to spend. Consulting trained architects and designers early on in your project will save you lots of time and money down the road as well.

boy, it’s HOT!

This time of year I’m always reminded of a bit from the movie “Good Morning Vietnam” with Robin Williams where he’s giving the “weather report” for the day and says:

“So Reginald, what’s the weather like out there today”
“It’s HOT, damn HOT. It’s so hot, I saw this dude in orange robes BURST INTO FLAMES!”
“So, what’s the weather look like for tomorrow?”
“HOT and WET. That’s alright if you with a lady, but it ain’t no good if you in the jungle.”

Friggin hilarious movie. I could watch it again and again and again…it’s that funny! 🙂

So what does this have to do with architecture or container architecture? I’m so glad you asked, cause I’m gonna tell you.

The most common critique that I find, and the most common internet search aside from “container homes”, is how to practically insulate containers for hot weather. Recently I was asked to submit a design and fabrication proposal for a 8 unit dormitory in Puerto Rico to be constructed out of 40′ High Cube ISO shipping containers. The number ONE concern of the client was quote “is it possible to insulate these containers to ensure a comfortable interior living temperature?” The answer is YES.

But first, the program. I was asked to provide a design proposal, originally, for a minimum of 12 dorm units on a single piece of property in San Juan, Puerto Rico. The lot, being only about 300 square meters is…let’s say it’s “small”, and unfortunately shortly after I began the design process, the client informed me that there is a 2 story height limit, which totally cut down the number of units we could have. That being said, we’re left with the 8 units. Each unit is to have a bedroom with a storage closet, a full bathroom, a kitchen area, study area, dining area and living space. All within a 40′ x 8′ x 9′-6″ space. Yeah, it’s a little tight, but I made it work. And I think it works quite nicely. Obviously we’re not talking about a ton of space to party in, but it certainly functions the way a dorm needs to. This is the typical unit plan.

The bedroom is probably larger than it needs to be, but then if you used a Murphy bed, you could have a bedroom and office space in one.

So, how do we take this single plan and make a multi-unit structure? We stack them horizontally and vertically, 4 across and 2 high, giving us the 8 units. Circulation to the second level is made by a simple prefab metal stair and balcony. The entire building will sit on poured concrete pad foundations at the 4 corners and intersections of the units. This GREATLY decreases the need for lengthy site work and coordination. This is the first floor plan showing the horizontally stacked units.

In order to insulate these big steel boxes and provide comfortable temperatures inside without completely breaking the bank with our electric bill, we’ve insulated both the interior and exterior wall faces with 2 1/2″ of closed cell SPF insulation for a total thickness of 5″ or about R-30. Basically, we created a cooler with a steel core structure. Oh yeah. 🙂

In the rendered images below you get a feel of the simplicity and scale of the structure. While shipping containers are small, you can see that they can be modified and designed in such a way to provide adequate living space for almost any building type.  Think for a second that we needed 2 bedrooms units. We simply remove the demising wall in the main living and kitchen area, modify the kitchen to be larger, possibly with an island, and we’ve created a double unit that is more open and inviting than just the single unit. Small changes make a big difference in this type of structure.

So, if you’re considering a multi-family structure, or even a single family, think about containers and then give us a call. We can save you time, save you money and build something that will last.

it’s granted, and I took it – @letsblogoff

These days, what DON’T we take for granted? We EXPECT so much out of life it’s a wonder that a third world war HASN’T broken out yet. As technology continues to push forward at breakneck speeds, we continue to take more and more things for granted. Electricity, microwaves, TV dinners, the Culligan Man, the internet, WiFi, Starbucks, those little chocolates on our pillow…the list just goes on and on.

And this is increasingly true in architecture and practice. With the widespread advent of digital architecture, clients, and even more than a few bosses, take for granted the time, concentration, talent and expertise it takes to produce a work of architecture…or even just a constructable one. And this time, this effort, translates to billable hours that are the first thing to be widely scrutinized and bargained for with clients and bosses.

One of my favorite little nuggets that always gets thrown out by both sides is “well, that should take you just a few minutes in AutoCad right?” It’s as if, with the advent of AutoCad, everyone now thinks that Architects and designers suddenly have all this free time. Architecture is now an instantaneous endeavor requiring no skill or thought or TIME. This, by far, is the one thing that is constantly taken for granted and is only getting worse with the push towards BIM software like Revit and Archicad. These new “pioneer” softwares are being hailed as the holy grail of architecture. They are the master key, the secret handshake, the special sauce that just makes architecture WORK….well, like any tool, it’s only as good as the person using it. And the person using it is still human. We can not alter the fabric of time, defy the laws of physics, nor can we be God (much as we think we can most days).

While new and sophisticated tools tend to make our jobs easier, they also come with their own brand of headaches. Take BIM for example. BIM is wonderful. It has allowed for nearly seamless Integrated Project Delivery, something that was almost unheard of 10 years ago. And it’s wonderful; we’re cutting down on mistakes before we get to the field, we’re coordinating more efficiently with consultants on the various building systems, BUT (there’s always a but) it also adds work and adds complexity to a project which is going to add time and additional expertise which is an added benefit to the client and will cost more money. But yet we continue to charge and get paid LESS for our services…..that ain’t cool.

All of these things are taken for granted under the simple and small assumption that time, and therefore billable hours, has decreased thus the fee should decrease. This is all caused because multiple people throughout the process are taking things for granted. The sophistication of the software, the talents and skills of the intern, the management from the project manager, the design skills of the principle and his/her ability to convey intent to the project managers and interns and the clients desire to spend as little money as possible on a project of increasing complexity and creativity.

If, instead, everyone involved could present themselves and their work product in an apples and oranges kind of way, do we think that less would be taken for granted, that less abuse would be dished out for us to take simply to retain a paying client? I think this bleeds into the larger issue of Architects more successfully selling themselves and the value of their services and sticking to that value. What do you think?

you mean it’s not a container!?

Recently r | one studio architecture was chosen to design a modern cabin retreat in the great state of Wyoming….yes, WYOMING. Truth be told, I had to look it up on Google Maps, because I had no idea where Wyoming was other than a general “over there” direction. As it turns out, Wyoming is actually quite nice.  It’s north of Colorado, south of Montana and sits between Idaho and South Dakota.

Cody, Wyoming, where our little cabin will be situated is in the northern part of the state east of Yellowstone National Park and north of the Shoshone National Forest.  The property has fantasic views of each.

The clients, a father-son duo, want a modern cabin retreat that they can use as a vacation rental when they are not in residence. The program is quite simple:

2 bedrooms, 2 baths, living, dining, kitchen and a 2 car garage with room for work space and tools (they are avid car enthusiasts). Like any good client I received lots of imagery depicting the style and materials they want to use. Budget is a concern, but they are going for a minimalist aesthetic, so that works to our advantage. Innovative uses for common materials will be key to the success of this project.

I am very excited about this project and I plan on posting regular updates as the design progresses and especially once construction starts, which will hopefully be in the fall before the snow starts falling and the ground begins to freeze.  Below is the conceptual floor plan. Things are still in development, but I think we’re getting close to nailing it down. And as always, I welcome any and all comments, suggestions and critiques (I do not cry easily, so don’t hold back). Cheers.

House the World – Jamaica

I’m so excited about this project and this organization.  House the World is a non profit organization who’s mission is:

“to provide sustainable housing solutions through open-source development. Our adaptability to ever changing scenarios, integrity to provide honest solutions, and charity to the poor defines the organization. House The World hopes to inspire others through transparent teamwork that leverages talent and aligns resources to help those in need. House the World will make a difference by providing safe, habitable, and vibrant housing solutions for people living in poverty. House the World’s long-term goal is to use technology to enhance collaborative networks, inspire others to help the poor, and provide culturally and geographically specific housing solutions for communities.” –

I was contacted by one of the founding partners of the organization to provide designs for a affordable single family residence that could be partially fabricated offsite and finished with local materials and labor in developing/struggling nations around the world.  Their first “site” is Jamaica.

I got a little overzealous and actually created two designs for them.  One is a design that I’ve been working on as a relief shelter that can be fabricated offsite, completely finished, dropped on site and be ready to go as an off grid shelter.  The second is a combination of shipping containers and earth bag construction, creating a design that is able to be constructed half offsite and half onsite with locally sourced materials and labor.

Both of these designs will be published as open source under a creative common’s license, which means that anyone can offer their own input to either alter or improve the original designs in order to make the most efficient and cost effective residence possible.

fakes, frauds and freeloaders

There’s an old saying an architect friend of mine once told me that has really stuck with me through the years. He said “good architects create, great architects copy”. I remember at first being extremely offended by this statement because it was my belief that all architects create. Eventually I came to the realization that my friend really is correct because quite simply, it’s all been done before and we’re all just recreating the same themes in different ways over and over again but to different effect.

But when do we cross the line from “copy” to “theft”?

I received a phone call last weekend from a non-profit organization, which for now will remain nameless, asking for help on a project because the “designer” they originally paid to provide a design for them to present to some interested parties for affordable housing had quite blatantly STOLEN work from ANOTHER non-profit and tried to pawn it off as his own. LUCKILY they did their due diligence and discovered this guy’s fabrication before trying to market these materials as originals and opening themselves up to legal liability.

It’s honestly hard for me even to write about this without jumping into a very long winded and profane rant about ethics and honesty and honor, etc etc.  So, instead, I’ll put it out there to you all – have you had experiences like this?  And, if so, how did you handle the situation and what advice can you offer as a way to vet future designers/architects to make sure that they are not a fake, fraud or freeloader?

a huge shout out and thank you

I’ve been at this blogging thing for a while now – coming up on 2 years to be exact.  I did not start this blog to be famous or to get lots of followers or clients or pick up chics or anything like that. I started this blog because I wanted to have a place to show my work (cause almost none of it has been built so far…) and to create an outlet for my musings on all things architecture, design and professional practice (I’m a legend in my own mind).

And in this pursuit I hope I have been successful and enlightening and entertaining and caused you to question some things about the “norm” in architecture. But that’s not why we’re here today. We’re here because over the last 8 months I have seen a monumental increase in readership on this blog and I need to take a moment and thank those who I have been lucky enough to associate with who have helped me along the way.  I truly would not have reached the level of influence I have without a bare few who said “hey I like what you have to say. tell me more.”  And allowed me a spot on their own digital platforms.  But before we get to that list, let me just show you how these few have affected what I’m trying to do each day.

blog stats from November '09 thru June '11

Above is a snap shot of individual hits to my site since it’s inception in November of 2009.  As you can see….well, I was unpopular the first year.  But that’s ok because anything worth doing is worth doing right and taking the time to build up. *editor’s note: snapshot taken on June 30th at mid day*

As you can see, since November of 2010, I’ve had a steadily increasing number of readers hitting the site. This is a result, almost unanimously, due to my experiments and investigations into container housing design and construction.  And also, thanks to those few bad ass bloggers listed below who have either supported me with tweets/links/posts/etc or allowed me a place on their blog rolls. This is not an exhaustive list, so if you’re not there it’s ok, I’ll still respect you in the morning. 😛
