What Does A Homeowner Need To Know When Building Their Own Home? An Interview with Karen

As 2015 ended and 2016 took off soaring, I sat back to think about what my clients, future clients, and every homeowner might like to know about building their own home. As the Architect, I'm here to help you every step of the way with charts, lists, project schedules and whatever you may need.  However, I think it's just as important to hear it from my clients.  So I sat down with one of my current client, Karen, to get her feedback on the process of building her own home.How many builders did you interview before you selected your current builder?"One!" Karen had intended to interview three different builders.  She got referrals, asked her friends, and had every intention of being her own general contractor for the projects.  She thought, with her connections, she could get great pricing and save money.  When her excavation contractor, who she knows, likes, and trusts, recommended a builder to her she thought, why not, let's hear what he has to say.  Karen says "He pulled into my driveway and starts  chatting with me. I immediately tell him that I want to GC my own project because I'm well connected and I know people.  To which he responded that he too knows people, and because he does repeat business with them, they give him even better pricing.  When I found out he could do the project as the GC for the same price that I could I was shocked. And it turns out he was right. I had friends in the trades that I thought would help with our project that never even called me back to give me a bid. It simply isn't worth their time for a one-off project. Honestly I don't even think we made it into the house. We talked for 10 minutes and I hired him on the spot without ever seeing his work. When you know your supposed to work with someone, you just go with your gut. I never interviewed another builder".What's so great about working with this builder?"As I mentioned, I wanted to GC my own project.  So I went to the builder with spreadsheets and cut sheets on everything I wanted.  Then he explained to me his perspective with other clients as we moved through the process. There were definitely glitches during the project, but my husband and I try not to sweat the small stuff.  We either fixed it if we could, or we lived with it and let go of it if we couldn't. Communication is definitely key" And from experience I can tell you that Karen and her husband are constantly on site, just like every homeowner will be with their project.  In Karen's words. "There needs to be an established trust.  You need to pick someone you can work with and he was willing to work with me"What has been the hardest struggle with building your own home?"Hmm, that's a tough one. It's all gone so well.  I guess that I wanted to be in by December 31st.  Everything was ahead of schedule and under budget, but now that we are getting down to the finish level we have had coordination issues.  The doors were backordered and won't come in for 6 weeks, but then we couldn't complete other finish details without the doors and that's when the schedule went right out the window.  When something doesn't get installed on schedule it affects other pieces of the puzzle. When other trades can't come in on the scheduled date you get bumped to the back of the line.  Our contractor is actually finishing today and going to another job.  He'll be back to finish the finish carpentry when the doors come in"What's you're advice for other homeowners who might deal with a similar situation?"Add 4 weeks to your move in date just to be safe.  And be realistic. I know my contract says December 31st, but I'm not going to hold my builder to that when this delay was out of his hands. Lots of things happen that are out of your control"What other advice would you give to homeowners? "If you're building on your own property check your homeowners insurance will cover the cost of the new build especially if you're financing it yourself. I woke up one night with a near panic attack that the new house might burn down. I called the insurance agent and had coverage the very next day. When I checked what our homeowners insurance covered it was only 3/4 of the cost of the build. Also, make sure everyone signs lien waivers so you're covered in the event of an incident. And on top of that, document every conversation so when someone gives you a quote and it comes back double you can say: What changed here? I kept a little journal though the whole process." said Karen.  As an Architect I often follow up meetings with my understanding of the scope and the next steps.  This helps to reduce confusion and gives everyone a hard copy to go back to incase there is a discrepancy.  I don't believe it is legally binding, but it's a great paperwork trail to figure out how you ended up somewhere.What was an interesting piece of advice that someone shared with you during the process?"I thought it was funny at the time, but someone told me: When you pour the foundation it will feel big, then when you frame the walls it will feel very small, but then when you put up the drywall the space will feel big again, but then you'll paint and it will feel really small, but when the furniture comes in and fills the space it will feel just right if you planned it right.  I thought that was unique, but it was definitely true during the build"What last words of wisdom would you give to other homeowners?"Building should be fun! It's the single largest investment you're going to make and you're going to spend a lot of time with the individual you picked to build your home.  So make sure you pick someone you can work with.  And lastly, this is your dream, do it with a grateful heart. You have a opportunity that lots of other people never will, so be grateful."

Your House is a System

BlogHouseAsSystemI think it’s time for me to introduce my readers to one of the most important concepts of building eco friendly homes.  House as a System.What do I mean when I say your house is a system?  It is a combination of inter-dependent parts that make up a whole building.  As an energy professional and an architect, that means, if I chose to change one part, I am affecting other parts of the system.  This may be in a good way, or it may be in a harmful way.  With the emergence of building tight homes, we also need to be aware of what we are trapping inside that previously exited though drafty or leaky areas in the home.  I was going to write “older homes”, but my experience as an energy auditor has taught me that it has little to do with the age of the home.  There are just as many leaky, drafty, inefficient new homes as there are older homes.It is extremely important today to understand the impacts of building more efficient homes.  This rule applies to architects, builders, and energy professionals.  The chemicals found in our building materials can be very harmful to your health.  Many products are made with formaldehyde or high volatile organic compounds (VOC’s).  Maine also has high levels of radon due to the rocky ledge that makes up our soils.  By building tighter homes, we must be sure we are not trapping harmful gases or compounds within the home.Building tighter homes isn’t just about air sealing with caulks and spray foams. Adding dense packed cellulose to your walls increases the insulation value of your home, but it also reduces the air infiltration.  When we reduce the air infiltration we can cause our atmospherically drafting heating appliance to blow exhaust fumes back into the home instead of out through the chimney.  We can trap moisture within the home, propagating mold growth and moisture damage. Many building professionals believe that houses needed to breath and that is simply untrue.   Houses do not need to breath, the occupants do.  And we need to be sure that the air our homeowners are breathing is both healthy and adequate.Houses that breathe draw in outdoor air from anywhere there is a hole or crack in the building structure.  This often times means that air is coming in from your basement.  When you think about the principle that hot air rises, you can imagine the cool air being drawn in from your basement and leaking the heated air out through your attic. Now if you think about your basement, you may be thinking about a dirt floor, all the chemicals you store there, or your heating system.  All that air that is being drawn in through your basement is introducing those chemicals into your living space.   We have a tendency to think of our basements as outside of our living space, but they are very much connected to every other part of your home.  Although the things you store there may be out of sight, out of mind, they are definitely not out of the air you breath.Before the emergence of energy efficient and airtight building, homes were able to dry out due to the air movement through the structure and the lack of insulation in the walls.  The homes would dry during the wet seasons of the spring and fall, however, these same homes would become very difficult and expensive to heat during the winter.  The energy community knew they needed to button up the homes, but at the time, they did not know that they needed to provide mechanical ventilation for healthy indoor air quality and they created several sick buildings.Now we talk about passive house building where there are less then 15 quarter-size gaps, cracks, or holes in a building structure and the sun heats the home virtually eliminating the need for a heating system.  These inter-dependent parts create a very efficient design.  In passive house standards, it extremely important to provide mechanical ventilation to the space. Providing fresh outdoor air to the occupants of the home eliminates harmful byproducts from the construction materials and excess moisture from cooking, breathing, and showering. Because the home itself has very little air infiltration, mechanical ventilation is often provided by a heat recovery ventilator or energy recovery ventilator. This allows the system to provide fresh air directly to the locations of the home that need it, like the bedroom, where you spend most of your time while you are at home.  Providing air directly to the locations where it is needed instead of drawing it in from wherever there are cracks in the foundation allows for the system to perform with precise calculations and reduces any loss associated with providing healthy indoor air quality.The increased levels of insulation from the code minimum help to keep heat within the building envelope.  Large south-facing windows can take advantage of the sun and heat the home through heating thermal mass, often a concrete floor.  All parts of that system have to work precisely together to make the house as efficient as possible.  If a new homeowner came in and decided to throw a carpet over the concrete floor they would reverse the effects of the solar heating system and require a larger heating system to be installed.  Tighter homes often do not have large gas cook stoves with 300 to 600 CFM ventilation hoods because there is simply not enough air infiltration to provide adequate supply to the ventilation system.  Without that adequate air it causes the ventilation system to “suck” on the house and will quickly burn out the motor in the fan.These are just a few examples of how the components of your home work as a system. So as you are building your home and thinking about making something that is more efficient, make sure you consider hiring a professional who can provide you with the information you need to save money, but also provide you with a safe and comfortable home.  It may sound daunting to build an energy efficient home, but the comfort level it can provide you and the energy it can save you is well worth the added considerations during the design or renovation process.
