Structural changes and a stud finder that actually works

We're finally back on track for the kitchen expansion after dealing with the rotten wood and Powder Post Beetle issues. Here's a quick review of the structural changes:
  • Open up the wall between the bathroom and kitchen (done). 
  • Reinforce the opening with a 4" x 6" header beam (done). 
  • Build the new bathroom wall about 30" back. This makes space for the fridge and a pantry (done). 
  • Cut out part of the bedroom to build a hallway and a closet. The hallway will have doors into the bedroom and bathroom. 
  • Open up the wall between the kitchen and living room (done). 
  • Reinforce the opening with a 4" x 6" header beam. 

This makes a nice open space between the kitchen and living room along with a bar facing the living room side. Moving the fridge really opens the kitchen up and moving the bathroom entry away from the kitchen is a huge plus. 


Off to the Rebuilding Center with some stuff to donate. I was careful not to damage things when I removed them so that they could be used again. 


What a great place. They have just about anything you could imagine and it's all priced very reasonably.  Lately it seems like prices of salvaged materials have gone through the roof and it's nice to have a place that doesn't operate like that. 




I built the wall in two sections so that it would go through the door. This also allowed me to carefully measure the opening it was going in and account for it being out of square. It was much easier to wiggle  the two pieces in separately. 


Bam!


Ok... On to the stud finder. I've had a number of these things over the years. Some of them came free with another tool, some of them I purchased. None of them really worked. I've seen some that make claims to greatness online selling for $100 or more, which sounded like too much, but I was almost ready to try one. I decided to give the Zircon i320 OneStep a shot. It was $40 and I'm very happy with it. 



Scan started.



The bars on the screen show when you start across a stud edge. 


The bars and the red light indicate exact stud center. 



Reenactment.


It also has a deep scan mode for finding studs on the exterior, metal stud mode, and a warning if you scan over any wiring in the wall. 


*Insert stud finder joke here*

Back to the kitchen. I sheeted the new wall with 6 mil plastic and taped the edges so that I can work on the bathroom without the dust or odor getting into the kitchen. I moved the fridge to it's new home and the kitchen suddenly seemed twice as big. Now we're waiting for the stove to be delivered. 


Notice my state of the art locking mechanism on the door. I lock our shed up at night by parking in front of the doors. Some day we'll have nice things...



Future home of a big open space. 


Things are coming together nicely now after that last setback. Today, Chance and I are going to finish the concrete form for the back deck and fill it with the gravel base. Annie and I also decided that we're going to wait on the metal roof until next year, so we're going ahead with the solar panel installation as soon as the installer is ready.

The Final(ish) Plans

Well, it's been quite a process since the first time I measured the house out and modeled it in Sketchup. We've been through about four major designs and I have over ten models saved with at least small differences between them. The plans are now mostly finalized. I say mostly because the changes that will occur from now on will probably be based on decisions we make when we come closer to physically working on them. I've just been told by so many experienced people to plan as much as possible ahead of time, so here it goes:


Bird's eye view of the property. We don't have much planned in the way of landscaping yet, but the garden that you see on the left side is already there, as is the shed. It's a very special shed that I'll talk about later in this post. 



I just recently got Podium, a rendering plugin for Google Sketchup. I'm not very good with it yet and I really don't know why it cut off half of our fig tree, but I'll figure it out soon. 


The main change you'll see here is that the front door will be moved to the actual front of the house. Some of the odd shaped windows on that side will probably be replaced with ones that can open and the south side of the house will get another window or two. 


Rather than doing that expensive and unneeded addition, we're pouring a 12' x 21' patio outback and giving it a good, solid cover. It may rain a lot here, but it as long as you're dry, it's rarely too cold to cook and entertain outside. The upstairs deck will get rebuilt slightly bigger than it was. 



These labels are hard to read so I'll break down the floor plan:

First Story:
  • Entry (top right). Moved to where the old gas furnace was. Storage area under stairs may be used for HVAC equipment. 
  • Living Room (bottom right). Stays the same size, but the wall between it and the kitchen is almost completely opened up and a bar is put in. 
  • Kitchen (bottom left). The main difference here is that we're stealing space from the bathroom to create a nook for the fridge and some additional storage. 
  • Bathroom (top left). Entry is now from the adjacent hallway which will be created. Still a full bath, but going to standing shower only because of decreased space. 
  • Laundry Room (above bathroom). This is where the solar panel equipment will be mounted to the walls and it may have to house some of the HVAC equipment if it won't go under the stairs. 
  • Bedroom (top middle). Slightly smaller because of the new hallway. If the bedroom and bathroom doors can go more toward the front of the hallway, the back of it will be converted into closet space for the bedroom. Otherwise, we'll have to cut into the entry way. 

Second Story is pretty much unchanged for now. The only thing different about this model is that I squared off the triangle shaped piece of floor near the top of the stairs so it could be a closet. 

I feel like most of the work I'm doing and these plans for structural changes are basically bringing the house to more of a blank slate. As we approach that mark, we'll be getting more into the selection of finish products, colors, etc. Some of those things have already been discussed, decided on, or even started. Each of them will have their own post, but here is a run down of what I know so far:

Garden - This is built and planted. Right now we have about 300 SF, but we may add more later. We picked up a big variety of organic plant starts at Portland Nursery and some excellent organic soil and top dressing from Dean Innovations

Water Shed - This is the shed I mentioned early that sits in the far back corner of the property. I'll be going into great detail about this in another post, but it's essentially a self-contained rainwater harvesting building. The roof is designed to catch enough water to fill a 3,200 gallon tank during the rainy season, which is enough to water our garden during the rainy season. I'm involved with the creation, sales, and marketing of this product and this is our very first one. More info can be found at watersheddesigns.com.

Solar Array - The solar array pictured is a 2 KW Photovoltaic (provides electricity) set and a 2 KW Solar Thermal (heats water) set. I'll go into more detail later on about how the electric panels are tied into the power grid and how the hot water panels are tied into the heating system. 

Roof - We aren't sure about the color, but I'll be putting on a standing seam metal roof before we can mount the solar panels. 

Insulation - I haven't had a chance to study the roof / ceiling assembly yet, but I'll need to find a way to add more insulation. As for the walls, it looks like we'll be using 2" x 2" battens on the outside to increase the wall depth. We have some options at that point for insulation, but we'll probably leave the existing 4" alone and just add 2" of rigid foam board in between the battens. This, of course, will be done after ripping off the old siding, but we have yet to pick out a new siding material. 

Kitchen - We really wanted to keep the look of the kitchen warm and classic. We're painting and reusing the lower cabinets and replacing the counters with Paper Stone. The upper cabinets will be replaced with open shelving. We're going to try to refinish the old wood floors if they're salvageable. Appliances will all be white. We have the fridge already and we just bought a vintage gas stove that looks sort of like this:


Annie is very excited about the stove and we're both really looking forward to having a functional kitchen again. 

HVAC System - This is still up in the air, but what we want to put in is a forced air (ducted) system which is heated by a hydronic air handler. The hydronic air handler uses hot water running through a copper coil to heat the home's air, rather than a gas flame. Whatever system we use, a Heat Recover Ventilator will be added to the mix. These units recover 80% or more of the heat from the stale exhaust air and add it back into the fresh air entering the house. That takes a huge load off the furnace. 

Finally, we decided not to pursue LEED certification on this project. I'm still following the steps that I would have for certification, but it would have made the project more complicated and expensive. There are some great resources available to verify that a house has been brought up to proper energy standards, including the Energy Performance Score from Earth Advantage. This is a very simple and effective approach to energy auditing and reporting. There will even be a place for the score on the MLS listing if we ever sell the house.

The Bugs

A few weeks ago, Annie noticed that a bird had built a nest in a vent on the side of our house. I'm not sure why someone put a vent on the side of the house, but it was now home to some baby birds. They sounded so cute and they made a perfect alarm clock every morning. That was all great until Annie walked into the little office room upstairs and found it crawling with hundreds of thousands of tiny little black bugs. 


It's hard to tell the size from this picture, but the thing they are crawling on is a small zipper on a plastic bag. 

We had to take all of our stuff from that room outside and every time we touched anything, they would start to swarm up our hands and arms. Annie got online and determined that they were Bird Mites, also known as Bird Lice. 

They were still coming in through the vent, so I went and removed the exterior vent cover and bird's nest while Annie cleaned the room out with water and vinegar. 




Fortunately, these things aren't hard to kill and they die or go away if they don't find a new host within a few days. We quarantined all of the items from that room outside for about a week just to be safe. 

The next surprise came when I started deconstructing the downstairs bathroom. 




It looked like there had been a slow leak behind the shower for quite a few years. The floor was rotted out and a number of studs were completed rotted at the base and not even supporting the wall anymore. As I got to removing the damaged lumber, I noticed a fine dust coming out of some of the pieces. It was a lot like sawdust. I didn't think much of it at first, but as I took things apart more, it became more apparent that something was eating the wood. 





I called a pest control company out to look at it and it turned out to be Powder Post Beetles. They seem to have only eaten around the damp wood, which is common for them, but they have been known to eat entire houses. I'm glad we caught it when we did, but it's been a lot of work fixing the framing they destroyed. 


Chance looks through the giant hole we just cut in the house, trying to figure out the next step. 



Once the affected wood was all cut out, we started piecing the house back together. 



We had to cut the rotten / eaten subfloor back a few feet and replace some joist sections.

Finally, we were able to get back to doing what we had set out to do a few days earlier. We opened up the the wall between the kitchen and bathroom and put a support beam across it. The new wall will go back about three feet into the bathroom and the extra kitchen space will house the refrigerator and give us some extra storage. 




First post in!


Deconstruction doesn't mean you don't still get to use a sledgehammer from time to time.



Finally! Now just two more beams left to do...

So the pests are all dealt with and remodeling is back on track. I'm just now finalizing the plans in Sketchup and I'll post them soon.
