Our design process – Part 3 – how to make the tiny house HUGE

One of our key design requirements was to make a gourmet kitchen. Another was to bring the outside in.  Today we want to share what has become the center of our design, the feature around which the rest evolved, and perhaps one of the most distinctive elements of our Tiny Home.  Yes, it is the 12′ wide open window door combination. It allowed us to take this Tiny Home kitchen and open it up to the HUGE outdoors.

We had seen folding glass windows as well as folding glass doors.  There were even some very innovative uses of a glass paneled garage door to open the tiny interior to the vast outdoors.   But it was this unique combination of windows and doors working seamlessly together that truly inspired us.

The pictures here show it opened and closed. It is an approximately 12ft (3.66m) wide unit split in half doors (to the right) and windows (to the left). A key feature is that there is no center post when it is opened, leaving a completely unobstructed view.

This was not without its challenges.  First we had to find the right supplier. After some research we identified several top notch companies that engineered some very impressive bifold units. We progressed with one at a time for several weeks until for some reason or another (legal Dept worried about liability of units in moving unit, design not capable of handling potential bumps in the road, won’t be able to handle this new design in 2018, etc.) they backed out. We went through this for a couple of months and then decided to design our own. A simple two door two window design with two way hinges should do the trick. We even found a custom door designer that was willing to create a door from our idea, but their legal department also said no warranty. For what they wanted to charge, sorry, no go.

So there we were, add custom door and window manufacturing to the to do list.

One evening, before we ventured into this new endeavor, we did one more desperate search. Julia found this fairly obscure, but promising provider out of Florida. A call the next morning revealed that they were the US arm of a German manufacturer, Sunflex and they said they were up for the challenge. They made sure to incorporate steel bearings and heavy duty parts at any stress points. They even offered triple pane glass for extra strength and insulation.

That this was a well engineered product was evident. It was shipped by boat from Europe and when it arrived even the packaging was impressive.

Secondly, making sure the structure could accommodate this wide span with a deck on top was not trivial.  This is where our selection of Volstrukt and their agile steel framing paid major dividends again.   They were able to design all the right supports and reinforcements necessary to make this a perfect fit.  Tiny Home Builders, provider of our trailer, also came up huge by working with us to get the necessary steel beam to allow for that large opening.

We love how it all turned out and this picture taken from the inside really shows it off well. We are doing our best in making this tiny home HUGE. It is Tiny Living Living Large.

Next up is the metal roof, incorporating the various vents and our roof top window.

Cheers for now.

Floating Stairway to heaven

Okay, after a break in our posts, it is time to get back into the swing of things.  We have a lot of news to share.  After spending some time in the skeleton of the house, using markers on the floor to show cabinet and walls, as well as walking through our 3-D Model, we made some drastic changes (more to come in other posts).  One of the more visual ones was the removal of our smaller loft which we called the reading loft.  It also had the boxed stairway going up to the roof top.   (here is the before and after – grey box on top right in first picture are the stairs).

Now with a wide open view to the upstairs, it really opens up the space.   In addition, it allowed us to design something we always talked about, but did not think we could do – a floating stairway.   As it leads to the roof-top, it made sense to call it “stairway to heaven.”

We researched the web to find a stair manufacturer, but no one had a set of stairs six feet high.  A shop in nearby Pennsylvania (next state over) looked promising and could do a custom design.  Unfortunately, after a few interactions, we were not quite convinced that they could accommodate our requirements and the price was very unreasonable.   Back to the drawing board.

Julia and I are absolutely in synch on this project and agree that there is nothing we cannot do ourselves.  So we resolved to tackle this on our own,   but we needed steel to build the brace and just as important,  an excellent welder.  To our surprise, a young kid (Neiko), running his own shop (Bulletproof Welding) said he would love to build the whole thing.  He came out to visit and we instantly liked him.  We agreed on a design and price and he said it would probably take a few weeks.  That was last week.

It was a great surprise when he sent us a video a few days later. 
He had the core laid out and wanted to show us a couple of options on how to handle the braces for the treads.  We chatted on the phone and also agreed on a modified tread design.  Two days later I got a text message asking if he could come to install the structure the next day.  Wow.

The install went smoothly, as he fabricated a bottom plate on site, welding it in place as well as created a custom clamping system that he bolted at the top to ensure it would not interfere with the Skylight installation.  Here is a video of Neiko doing the cutting.

The treads are wood, routed on the bottom to allow the bracket to be inset into the step.  Here you can see Neiko placing the treads on top of the metal brackets.

We agreed that I would do some additional routing on the edges.  We will add another piece of wood underneath and stain the treads at a later date.  To say we are thrilled with the look of our “stairway to heaven” is an understatement.

What do you think?

Too cold outside, so let’s look inside

With the weather too cold to make a lot of progress, here is a closer look at the design using a video walk through. Let us know what you think.

House of Steel

After making the foundation (trailer) choice, the next big decision is how we are going to frame and insulate it.  There are a number of options to consider.   Structural strength, weight, insulation value, and ease of building to name a few.

When you consider that this house on wheels is going down the road at 60-70 mph (100+ km/h) on a regular basis, you start to realize it needs to be built for hurricane conditions.

tiny-house-frame-tiny-houseWe started down the traditional route of stick building using traditional 2×4 dimensional lumber.  This is by far the most common approach.  If we needed help to build, most any local framer would be experienced in wood.  It is also the least expensive choice.   However, it is heavy.   And it will take us some time to build, even if it is just a small tiny house.  It will also take considerable care to ensure that the structural integrity is intact, especially given the fact that it will be exposed to hurricane winds. Also, let’s not forget the rooftop deck, you may remember from our design, which will need to withstand hundreds of pounds/kilos.

Second, we really liked the idea of using SIP (Structurally Insulated Panels).   These are pre-built panels using plywood (or most often OSB), sandwiched around a foam core J-Deck_Inc.SIPmade of expanded polystyrene (EPS), extruded polystyrene (XPS) or rigid polyurethane foam density insulation.  The manufacturer constructs the entire home and then disassembles it and ships it for an easy build on site.   The main advantages, from our perspective, were very high insulation values (as high as r-27 in a 4″ wall), strong structural integrity, and the ease at which we could build the frame of the house.   This solution was slightly lighter than the pure stick-build but the most expensive option.  Another challenge with this option is the extra work needed to route electrical wires and plumbing as the walls are solid foam.  There are workarounds, but in the end we decided against it.

So then we have the steel framing approach.   You see steel framing in commercial ACT_THEME_HUBSPOT_SITE_HOME_PAGE_GRAPHICS_1applications all the time, but not so often in residential.  It is definitely more expensive than the stick build route and finding local experienced help is not going to be as easy.  However, we found these challenges were definitely overcome by its benefits.  The number one reason we choose this path was due to weight and structural integrity.  By our estimates, we can save close to 3,000 lbs (1,360 kg) versus the stick build.  This includes using the lightweight and insulating foam sheeting on the outside. A significant factor to making this home as lightweight as possible. It is also stronger than any of the other options, easy to assemble as it also comes in prebuilt sections, and completely impervious to moisture, bugs, etc.  We were sold!

So there you have it.  House of steel.  Can’t wait for it to arrive so we can make it a reality.

First look at the actual design

Last week we passed the gate of no return, we ordered the trailer.  True to our earlier post we went with a gooseneck trailer, 26ft (7.92m) base with an 8ft (2.4m) gooseneck platform.  We ended up going with Tiny Home Builders as we found their trailers had a very strong design and they were able to accommodate our special customizing features.  The sketchup file of it should arrive in the next few days and the trailer itself is about 6 weeks out.

Talking about sketchup, this is some great software.   When we started to come up with the idea for the Tiny house, we drew on plain paper using a ruler.  We used a cm to represent a foot as that would be smaller on paper than an inch and our ruler had it marked.  We still had to tape two regular sheets together to make it fit.  As you can imagine, that got old really fast, but was good for some initial pie in the sky ideas.  Drawing in 2 dimensions seemed natural, so we searched for some free software we could use (yes, even I admitted I could not do this in PowerPoint, which is my goto for everything).  While drawing on the computer in 2-D made measurements and scale a lot easier, it became increasingly difficult to figure out the interior and how all the pieces fit together. If they even fit at all.  Enter Sketchup.  Very capable, priced right (free), not too difficult, and lot of fun (okay, at least addicting).  But most of all, the resulting output is impressive and we can import drawings of actual appliances and designs to see how they will fit.

OutsideSideViewSo here it is.  The initial look of our design.  A contemporary, clean look that incorporates our many requirements. Siding is cedar (the reddish parts) and the rest is trimmed in cedar with metal panels. When we arrive at our destination, we will unhook the truck from the house and attach cedar panel skirts underneath the gooseneck creating a tiny garage for our bikes and additional equipment. In this first view, you can see the two decks, including the rooftop.  We placed solar panels on the top as well as a rooftop access window that opens up fully for easy access.  The main deck is 15’x8′ (4.6m by 2.4m) and is stored in two sections under the trailer during travel.

KitchenHere is a view of the kitchen from the outside.

BirdsEyeThis top view will give you a glance of the inside.  The master bedroom is over on the right, just a few steps up a stairway.  We have plenty of closet space and drawers.  The reading loft also has a few more steps on it that leads to the rooftop deck.  Kitchen is in the center of the home with a full size panel ready refrigerator/freezer, top of the line stove, convection oven, hood, and wood burning stove/oven combination.  Adjacent to the stove is a panel ready dishwasher, farmer’s sink, and wine rack.  At the other end is a sleeping loft and underneath that is a full size bathroom and laundry area.

LoftViewThis shows the view from the sleeping loft across the kitchen to the living/office/dining/sleeping room.  Yes this space will have multiple uses with transformational furniture, hidden features in the wall, etc.

Our design process – Part 1 – the trailer

There are so many great designs of tiny houses on wheels out there. Just go on Pinterest or Google and you are sure to find one after another.  Yet, we know we wanted something that reflected our style.   We live in a very traditional classic home today – so we decided to go with a more modern look.  After all, we are no spring chickens, the tiny movement is all the rage among millenials, so we have to do our best to fit in.

As we started on our sketches, we had a few requirements.

  • A serious cook’s kitchen – that is the heart of the home
  • Space for two separated office areas as we both work virtually
  • A master bedroom with standing height
  • Additional sleep capacity for at least 4 persons
  • A bathroom area with a separate door for the toilet
  • Lots of light through windows
  • Incorporate outdoor decking to make it part of the living space

Did we mention we have to do this in about 300 sq ft?  Width could not be more than 8.5 ft, height no more than 13.5 ft.  The one parameter we could play with was length.  Oh yes, with size comes weight, which equals the need for a large man size truck to tow it.  More about that later.

We did not know much about Tiny House On Wheel trailers, so at first we tried to shoehorn all this into a traditional trailer 24-26ft in length.  It was getting frustrating as we always had to give up something.Trailer 24ft regular

It took a while, but we soon figured out that there was a whole new world out there, the Gooseneck trailer.  It added 7-8ft of elevated space, usually accessible via a few steps, and it provided standing room.  Voila, our master bedroom.trailer32frGooseneck

There are many more details we needed to decide on as well as many manufacturers to choose from, but for now we had selected our foundation choice.   We since learned that a Gooseneck trailer is much preferred when it comes to towing as it is much more stable and easier to handle – great bonus.

As far as size, we started at 24ft of the basic trailer with a 7ft gooseneck.  That grew to 26 ft and an 8 ft gooseneck.

Next post is about some major choices we made which impacted the rest of the design.
