Updated Floorplan

This is an updated picture of the floor plan. Zach and I have been grinding through the utility cellar and have thoroughly enjoyed working with the greenblocks and will soon be working above ground on forming the finished concrete slab. Mike, our engineer, came up with the great idea to pour our 4" insulated radiant slab directly on grade rather than suspending it on joists above a problematic, building-code intensive crawl space. Not only does this save resources mostly in the form of lumber, but it also allows us to raise and lower the final floor elevation without any more effort than what it takes to shovel the dirt (which is just a free workout as far as we're concerned). So we've opted to lower the dining room floor height about 7" below the kitchen floor height while finishing both surfaces and the step between them in polished and dyed concrete. The idea is to "compress" anyone entering the house when they stand on the entry platform so that the full effect of a ten foot ceiling in the dining room can be contrasted before stepping down.

The breakfast bar will act to divide the space between the dining room and the kitchen in an open floor plan concept. The diffierent elevations will allow for a nice, tall bar for visitors to saddle up to from the dining room side while also providing a sizeable countertop workspace for whoever is cooking. We designed the bar to follow a curve based on the Fibonacci sequence, a natural pattern that occurs in nature countless times in forms like a nautilus shell or a fern. We worked this into the design to give a nod to the concept of biomimicry - the idea of using nature as an ecological standard to judge the "rightness" of our innovations. After 3.8 billion years of evolution, nature has learned what works and it is our belief that such an intricate blueprint leads to aesthetic beauty.

Onward and Upward

This is a picture of the lowest point we will reach in the renovation. Yesterday, Zach and I mixed 30 bags of concrete and poured this 8"x16" reinforced concrete footing. These first 8 inches of upward progress will support a 6 foot ICF wall (Insulated Concrete Form), and a 4" concrete slab to be formed and poured in the coming week.

Zach and I are enthused to try out a relatively new and emerging green building product in the form of our ICF utility cellar.
ICFs are made from expanded polystyrene (EPS - same stuff they make Styrofoam coffee cups out of), but they represent a huge energy savings with insulating values of up to R-50, and provide amazing strength with a perfect and continuous reinforced concrete form. EPS is not our favorite green insulator considering some of the biodegradeable alternatives (recycled cotton, recycled newspapers, soy, and straw to name a few), but EPS has come a long way.



We chose a company called Greenblock, whose simple leggo-like assembly system, high R-values, and handy embedded furring strips made for a perfect combination. Additionally, although Greenblock is a world-wide manufacturer that has been used as a standard European building system for over 30 years, they have a small local distributor in Woodland Park. Zach and I were pleased to be greeted by a professional and friendly old hammer swinger named Jeff who graciously agreed to hang out and wait for us after hours to sell us the meager two-bundle order we were requesting. We were treated to a full introductory class in Jeff's office and later followed it with a quick wall building tutorial in the warehouse. We certainly didn't feel like we were dealing with a multi-national corporation. Jeff made it easy for us to choose Greenblock, and we hope to host him for an ICF class in Denver on our next project this fall.



The ICFs, which come in 4'x1'x11.25" blocks, will be stacked like a brick wall on top of our new concrete footings at the bottom of the cellar and braced with standard framing lumber for support. We will then pump 4000 psi concrete with a mixture of %20 fly-ash (to replace some of the Portland cement - a diminishing resource in increasingly high demand as China and India pour more concrete foundations and walls than we can imagine) into the bottom of the forms and fill them like a pudding cup. It's a clever and elegant system. We're excited to move forward.



This is a huge project for a two person crew, and at times it can get a little daunting. Fortunately, our requirement to recycle or reuse no less than 75% of the waste materials from the project has facilitated the building of a few morale boosters in the form of landscaping. In order to collect the rubble and dirt from our demolition, we built outdoor planter boxes out of FSC-certified (Forestry Stewardship Council) 2x6s and brick posts. The boxes we've built so far have provided a need for over 10 cubic yards of landscaping fill. The rest we take to recycling facilities first, and landfill last. I'm proud to say that we've only taken three trailer-loads of waste to the landfill so far, and I feel confident we will make our goal of 75%.



Now that the boxes are filled, Hanna and Malin have started to gather a collection of beautiful native grasses, shrubs, and flowers and have started to implement a drought-resistant and low water use landscape design. The house is whirring with a wonderful feeling of progress. Although it may look like a bunch of vagrants and hippies are camping out waiting for Phish tickets, this EcoEnovation is in full swing, and before we know it, it will be time to dress her up and present her to the neighbors. Until then, we persevere!

Back to Work

Hanna and I have just returned from the East coast where we had a wonderful hiatus from the tasks at hand awaiting us in Denver. Work resumes next week with the arrival of our old friend Zach from San Diego. Zach is a proffessional carpenter, a surfer, and a journeyman who has graciously offered us the better part of his summer to join us in building the "EcoEnovation". With his help, we hope to quicken the pace as we move from the demolition and deconstruction phase into the rebuilding phase.

We will start by first building Zach's and Hanna's sister Malin's sleeping quarters in the garage. I like to call the garage (which is unrealistically small for our Outback) our new "bunk house". The EcoEnovation is turning into a real barn building party with friends and relatives passing through Denver all summer, and with the house in a constant state of flux, accomodations are limited. The garage is clean and dry with electricity and is therefore a perfect candidate to provide a bunk house to our transient guests. We've also placed our new refridgerator in there with our microwave on top rendering the space into a rustic kitchen. There are two tiny tiny rooms adjoining the main bay of the garage that could be used as a mud room or utility closet, but instead, we will install a few sleeping platforms to constitute what Malin calls the sorority and the fraternity house.



There is a small 5 foot wide outdoor corridor between the garage and the house that we have transformed into an outdoor hygiene facility. With the help of my good friend Adrian, we installed a custom door and frame to form the corridor into an outdoor room. The door was composed of deconstructed floor joists and 2x4s, sheet metal from the old air ducting system, and a series of beautiful cedar slats recovered from one of the many floor decks we removed. Inside the private space created we have placed a solar shower on a pulley system, and set up a dishwashing station in lieu of not having a functioning indoor shower or kitchen. We love the solar shower so much, we've decided to add a permanent outdoor shower to the plan.




After completeing the bunk house and moving Zach and Malin into it, we will rip the rest of the floors and framing out of the 1st floor. We need to have the entire inside gutted down to the dirt below the old rotting floor joists so that we can bring in our structural contractor to poor two grade beams along the entire length of the foundation. We will then install new floor joists on the new beams inside the old brick foundation and build our radiant slab on top. We're all getting excited to start building upward from a level and square platform. Things are proceeding in style!
