Design - LEED Platinum Home Progress Report

DESIGN


We have begun to design what will be a total gut renovation of and addition to the clients' existing home.

The size of the site is limited and so the house size has to be small. The house as existing is approximately 1800 square feet. The lot is 1/7th of an acre. They are already over on their coverage as stipulated by the town of Darien. There is a detached garage on the lot that counts as coverage. Including the garage they are at 21% coverage. Allowable for their zone is 20% coverage.

The house is from 1920 and existed before zoning regulations. Though their lot is 1/7th of an acre their zoning is in the ½ acre zone. So in a way their coverage limitations seem extremely unfair- as the neighbors who are in the ¼ acre zone – who have the exact same sized lot-  get to have a good deal more coverage. The bottom line is that the town is tough on its zoning regulations and if they want to build anything they have to actually reduce their coverage to 20%. So the garage will be town down. We will design an addition that will bring the house to a few square feet less than 20%- to show good effort and to give ourselves a tiny safety net in case we are off by inches in surveying or construction. This is all fine with us.

One of the goals of building green is too build smaller homes and having strenuous parameters in place actually makes the design more interesting and challenging. Though the client may have ideally wanted a few more feet of elbow room they ultimately would not have designed a much bigger house even if they had 10 acres.

(Why DID the client choose to add on to this house instead of moving to a big lot somewhere else? Well actually the answer is a mixture of many things. The house is about ½ a city block form the train station so the husband can walk to the train, take an hour ride into Manhattan, walk a few blocks to his office from Grand Central Station and do the whole thing in the opposite direction in the evening to come home. The guy lives in suburbia but might not touch his car for 5 days! The house is also close to everything in town. Almost all shopping and amenities are within walking distance. So mom and the small daughter can spend their days car free as well, if they like. And thirdly the house is across the street form the town park. There is lots of open space and a beautiful pond right out their front door. You actually cannot find a more perfect example of where you would want to put a LEED certified home and provide a greatly reduced carbon footprint for people who care about just that.)

The existing house is an old simple colonial. It is simple and nice, though not particularly beautiful or unique, but it is in the historic district so we also have to please the town’s historic commission. This is fine because the clients want a traditional home. Though we, as architects, do enjoy designing modern or unique houses, we also love historic homes and see this one as such. We immediately all share a vision of turning this house into a lovely traditional colonial- true to historic in its detailing and proportion. Currently the house is not symmetrical and has none of the trim of a historic colonial. It was probably a less expensive sort of builder home of its time. There are many like it in the neighborhood. So our goal is to bring it some of the design and a bit of the grandeur that it would have had, had it been built by a wealthier family in the 1920’s.

Inside, the clients (like all of our other clients) want open-ness and light. The back yard is very private and we envision the house opening up in the back and the sides toward the back so the family can have an indoor outdoor feeling sort of lifestyle with loads of natural light flooding in. The front box of the house will retain all of the elements of a true colonial and the back box of the house will be more like a garden room or solarium with bigger windows on both the first and second floor . The first floor plan is to include kitchen, dining and family rooms all open to each other in the back/ solarium part of the house with mud room, formal entry and small parlor with an inglenook in the front of the house. Upstairs there will be 3 bedrooms – a master suite and 2 children’s rooms. We will go up one more ½ story and add a third floor guest room, office and bathroom. The total square footage for the new house will be 2700 sf (existing was 1800).  So we are adding 50% more space than they originally had.

LEED

Keeping the ideals of green building and the point system of LEED in mind (though we are still debating whether or not to pursue LEED Certification) we are all aware that we are doing great on both accounts. The lot and location could not be more perfect for meeting LEED expectations. It is a previously fully developed site, close to hundreds of amenities and transportation options. The size of the lot is 1/7 of an acre and satisfies a primary density requirement for single family development. The house size as well will please LEED. The final house will be about 2,700 square feet. In order to not be penalized by LEED a four bedroom house (which this will be) would be 2,600 sf. We will be penalized 1 point but for Fairfield County this is considered a very small house and the decision to add the extra 100 sf seemed worth it to the client. (Most of the houses we have done in Fairfield County CT would be penalized many more points as you are penalized 1 point per every 100 sf you go over the size maximum.) We feel we are doing quite well, especially considering that about 500 sf of this house is basement storage and mechanical space....not habitable living space. (Actually we are not 100% sure we will loose a point because we are not 100% sure that the mechanical space is included in the sf calcs.  If it is not then we are 100 sf under square footage...and maybe get a point!)

Another Potential LEED Home! We're Hired!

ANOTHER Potential LEED Home! WE'RE HIRED!

 

We are hired by a family in Darien CT- the town next door- to help them design a major addition and gut renovation of their exiting house. We had actually met the family before.  A year earlier we had interviewed to be their architect. They had gotten our name from two separate contractors – the two contractors who I would say truly know how to build a green home. We know one of the contractors because we had worked on and off with them since 1999 when I designed my first super energy efficient gut renovation/ addition. They were the only contractor we knew at the time who knew a lot about green building and I would see them at all of the green building conferences both local and national. We know the second contractors from simply being in the same small circuit of professionals who really care about building sustainably in Farifield County, CT.

We are not exactly sure why we did not get the job the first time around. It can be a number of things that lead a client to choose one architect over another Could it be we are women? Could it be that though in our 40’s we look a bit younger than that? Maybe there is just not that perfect immediate understanding? Maybe our fee was simply higher?

FEES

In general architects charge in the neighborhood of 10% of construction cost for a job. Everyone bills and contracts slightly differently- but that is the basic goal. It is extremely difficult to keep an architecture firm running if your fees are less than that. In Farifield County, truly established and well known architects ask for and get 12-15% or more. Then there are many one-man-show architects who ask for 7-9%. I have architect friends in the Midwest who run firms happily on 8% fees. They live very middle class lives. Most architects do not make a ton of money unless they can command 15% fees OR unless they were born wealthy. Architecture truly is the gentleman’s profession. The fees we proposed the first time around were in the neighbor hood of 10% of construction costs. We have a 3 part contract: 2.5% for Design (the creative brain storming and basic drawing needed to find and convey an elegant solution to the problem at hand), 5.0% for Construction Documents (the drawings and specifications, etc needed to get permits, bids and construction completed) and 2.5% for Construction Administration (the weekly job meetings and general over-site of the job construction.).

Last year, this client was deciding between us and one other architect. The other architect- the one they chose the first time- was an older male architect, a one-man-show. He had come recommended to them by some friends. He told them he could design a green home (as this was their major priority). I have no idea if his price was significantly less than our or if he simply had more gravitas. It doesn’t really matter, in the end he wasn’t designing for them what they wanted and he was not responsive when they asked for better.  They called us about a year after our first interview and asked us to step in. As they had already done a fair amount of design with the other architect we changed the first phase of our fee from a percentage to an hourly fee. We knew we would not need to spend nearly as much time in design as the client had already seen the space potential and thought through a lot of the design options by working with the other architect. Actually many architects find that their best clients, is the client who has already been ‘broken in’ by a different architect.

Anyway it was the beginning of what we would find to be an extremely satisfying architect-client relationship. Not only do we all get along well, but we all have the same direction in mind for the house. We each wanted the house to be very energy efficient, clean, healthy and natural. We share an aesthetic direction as well. We found along the way that we all also hold very similar views about lifestyle and environmental politics. We were pretty sure that we would hire one of the two highly knowledgeable green contractors that I spoke of earlier to do the work. This is a great recipe for bringing a green home to fruition. The goal for the house is the same for everyone.

 

LEED

We discuss the options for rating the house. LEED, Energy Star, NAHB (National Association of Home Builders.) The clients are interested but don't feel an overwhelming urge at this point to put a lot of money into getting rated by anyone. We agree to all think about it as the job progresses.
