0751 Suburban House - first scheme

Today we'll look at one the schematic design ideas for this project site. This is the scheme described in the original posting as gathering the rooms around a high ceilinged living space. Today we will look at more views of the rough massing model, and a very rough floor plan of the house. The image we saw in the first post. click the link below to continue reading. This scheme made an effort to "gather" the living spaces around the living room, making it a central hub of the house. Here is the ground floor plan: You note from the massing model that the bedroom wing which is opposite the driveway side of the house is a half level or so down from the living room level. The intention was to put the master bedroom on this lower level, increasing its apparent distance from the living spaces. The entry to the house from the ceremonial front was on this same half level below living, and the entry from the garage deposited you at the same place. So looking at the plan, the entry hall across the front of the house narrows where it turns towards the master bedroom, a door to the suite not shown on this plan. If heading up from the entry you come to a corner where the door from the garage would be, while you were offered views into the living space through a screen wall of some sort. The stair up to the living level brings you to the corner of the kitchen work space under a lower ceiling. The higher ceiling in the living space ends in a large windowed wall with a terrace beyond. The splayed geometry of the house is generated by the site, and has a nice effect of opening the house to the landscape. At the far end of the living room is the stair going up to the bedroom level. Now here on the second floor plan you can see how the secondary bedrooms overlook the living room. The idea would be that they could have sliding panels, or internal openings that made them like a loft overlooking the living space - remember the master bedroom below is a half level down, so these bedrooms are only a half level above the living room. A bridge like connection spans over the entry hall below bringing you to the studio space which sits above the garage. The circulation in this scheme is deliberately circuitous - it wraps around the living space like embracing arms. This was part of this effort to gather around the living space, expressed in another dimension, through the circulation and motion through the space. Several other views follow. Fill that would be required is not shown in these masssing studies, so the floor level can be strangely off of what would be the final grade. The rear terrace here would create an outdoor place at the level of the living room floor, which is not reflected in this rough mock-up. So that was the first design idea. Ultimately it was abandoned for a number of reasons, but I still find the central living space and its relationship to the surrounding rooms compelling. The lower level master bedroom is also a great adaptation to a sloping site, but a site that slopes side to side rather than front to back.

Letters from Sweden - wiring zen

Wiring is perhaps not one of the most exciting things to talk about if you are a house design junky. Getting power and lights to where you need them is unglamorous and underappreciated. But wiring is probably the biggest factor that determines whether a prefab house can arrive at the site finished on the inside, or empty - just a shell.

Why is that? The reason is that wiring is like the nervous system of your house. It runs in every wall, reaching out to switch locations, and lighting locations. It reaches every corner of the house without regard for whether or not those walls want to come out to the site in one piece or not. If a room can not come out to the site in one piece as it does in a modular house, then its likely it will come without the wiring. If walls come without wiring, then that means they are going to come without finishes because the wiring has to go in first.

0751 Suburban House - project background

In a departure from the usual blog topics here I'm going to be starting a series of posts about local project, a custom home, that I've designed for a client here in the Delaware Valley region. While this is not a stock plan or a prefab several of the design schemes that we abandoned during the design process may ultimately find a second life as a house design in our stock plan catalog. So, while we will eventually arrive at what was the final design, its going to be more about the journey and looking at the sketches of the house designs we left behind, and seeing if any of them generate some enthusiasm and longing! Lets begin with some background on the project so you can understand some of the influences, pressures, and limitations imposed on the design. The site is a parcel of 3 acres in a low density suburban zone outside of a small college town. The proportion of the property is a narrow rectangle with the rear closing to a point. A good deal of the front end of the site is consumed by wetlands, and its wetland transition zone, which can not be disturbed. This moves the home site towards the center of the lot, a good distance from the road making for a fairly private setting. This influences issues about how the house presents itself upon approach. Does it want to have a prominent "front" door when it really does not have a street life, or should it focus on the inevitable vehicle arrival? click the link below to continue reading. Another strong site influence oddly enough is the septic system. The septic design called for it to be located on the highest spot on the site, gaining the most distance from the relatively high water table. That meant that the home site was actually pushed down slope from the septic site, but if to remain on gravity feed to the septic then the house had to be at higher elevation. This put the first floor level of the house a good distance above the natural grade. So where the natural inclination would be to meet the landscape casually we were at a height above it, as you might be in an urban townhouse, except it was not driven by a need for privacy, but rather from the technical demands of the site. We were facing a contradiction that we would have to attempt to resolve. The house program consists of 3 bedrooms, 2.5 baths, in about 2400 sqft plus a home office/studio space and a two car garage. Ample area for what is a very common program of space. Tempering it was a desire for an open plan living, dining, kitchen and "gathering" of the two secondary bedrooms around the living space - encouraging their casual use for other functions for exercise and home office and the occasional guest. An interesting condition, yet it could not undermine the use of the rooms in a more conventional mode by a family with children. We explored several different alternatives which I will briefly introduce here. In entries to follow we will look at each design more closely. Some of these were developed only very roughly, and some not even worth showing here won't make an appearance. Gathering the rooms around a high ceilinged living space. Creating an entry forecourt between the garage and house. Living spaces on top of the remainder as plinth. A mulit-level interior space within a simple geometric volume. An inhabited wall defines the living space.

Virgina Plat House - windows in

The windows have been delvered and installed at the Virginia Plat House. Closed in, if not completely weather tight, they are in the clear to begin HVAC, plumbing, and electrical work inside. You might notice that the windows are green (as in color, not sustainability). Nothing remarkable, but these are Andersen 400 series windows. Since like the beginning of time these windows were available in only 3 colors - white, tan, dark brown. Bleah! Nothing wrong with those colors, but Andersen offered no options for using the windows to introduce some color into your house. Meanwhile other manufacturers have been expanding their color offerings. I don't know if Andersen is experiencing competitive pressure because of this, but they have started offering a dark green now as one of their standards. Its a great thing, especially if you want to use a different color for the operable windows as the house designs show in our illustrations. There are three more photos of the house with the windows installed posted at the flickr set for this project. Also remember to look at the LamiDesign Flickr photo pool to see all the photos from customers documenting the house designs under construction.

Letters from Sweden - a window's tale

In our last installment of the Letters from Sweden we looked at the panelization technique used by the Swedes and some of the administrative barriers to its adoption here. Today we'll pick up where we left off and consider some of the products that go into the Swedish panels and how they support the panel building technique. We'll look at windows, how Swedish window units are different than US window units, and how this plays out in the construction.

Virgina Plat House - wrapping up

A quick update of the Virginia Plat House . Since the last entry the wall and roof sheathing has been installed and the house wrap is on. The owner reports that windows are on the way. There are a few more photos of this stage of the work also posted at the flickr set for this project. Drop in on the LamiDesign Flickr photo pool to see all the photos that we and others have posted of our house designs under construction.

New Mexico EcoSteel - EcoSteel work essentially complete

The EcoSteel pacakge for the New Mexico EcoSteel House is more or less complete. Photos from the owner show most of the components in place, and the house and other structures fully trimmed out. Interior work at the house will be ongoing for a little while and we hope to have updates of the finished interior when its done. But until then we have new photos of the structures by the owner. click through the link below for more photos. Here the covered walk between the house and garage is in place and we can see all the trim on the house now. This photo would be late in the day as the entry side of the house faces westerly. Sitework remains to be done and I am not sure what the owner's plans are in that regard. It would be nice for the indigenous ground cover to reclaim the disturbed construction area and grow right up to the house. You get more of a sense of that vision in the second photo below. Remember you can see photos of the entire build on the Flickr New Mexico EcoSteel House photo set, and all the EcoSteel projects in the EcoSteel photo pool.

Letters from Sweden - panel building in Sweden vs the USA

Ok, we've been beating around the bush, setting the stage, trying to understand the context in which this Swedish building method exists. If you've been following the series you get it, its dark, its cold, there is no building season for the better part of the year. They need a factory based system to have an industry there, and so they do. Lets look at it. You've picked up by now that the Swedes are panelizing their houses. The walls are being assembled to the greatest extent possible in the factory. Windows and doors are installed, exterior siding, interior drywall. This means everything else within the wall is in there too - insulation, wiring, and plumbing where it exists. The studs are precut to the common height, and walls are laid out on great tables with the carpenters working at convenient work height. Sheathing, air barrier, and siding is applied and the panels flipped to gain access to the work that proceeds from the inside. Wiring conduit, plumbing, insulation and vapor barrier are all installed before wall board is applied. Some of the drywall is left off in strategic places to facilitate the installation of the panels on site, and this must be installed in the field. There is not genius in this, but never the less its near impossible in the US. Lets look at why. First off we have issues with construction inspection conventions in the US. Construction must be inspected before it is insulated, closed in, and the underlying work is obscured. Framing, plumbing, and electrical work are all inspected at this point. The modular industry has established a practice of third party certification to work around this, but this method would require a different routine as the proportion of site and factory work is not the same. Modular is more or less done with the set of the modules. Panelization requires the field inspector to pickup more of the inspection work again in the field, and I predict the blurring of lines of responsibility to elicit resistance. This is essentially an administrative obstacle, but real enough. This obstacle does not exist in Sweden. Second are issues of products and standard construction practices. In Sweden products are designed to facilitate this panelization. In the US they are designed to be installed in the field. This purposeful design of construction products allows the Swedes to optimize their process. They are not fighting with the construction to break it into panels, like we would here. Next we'll look at some of these products in more detail. Previously: Letters from Sweden - Europe is different, Sweden is not, sort of..

Austin Porch House - Plat House comes into its own

Siding panels are going up on the Austin Porch House project and the big news is the progress of the Plat House. Last we saw a bunch of sticks going up - in the new set of photos from the owner it is now most certainly a house. Across their courtyard you can see the Plat House facing the Porch House. This has been one of the most innovative uses of our house plans to date. With the usual household program spread between the two structures the owners have created their own "village". The variety of spaces they will have available for family life will be very rich indeed. More photos after the jump link below. Here you can see the interesting pattern of siding they have chosen. It appears to be a smooth faced cement board siding panel, but laid up in varying exposures. This is a treatment you might often see on a traditional cedar shingle siding and its really great to see this reinterpreted in a contemporary material like cement siding and used here. Check out the Flickr set for this house where you can see all of the photos to date. And these photos are also part of theLamiDesign House Plan photo pool.

Austin Porch House - roof's on, Plat House framing up

A big update from our customer in Austin. The Porch House is moving right along and is all sheathed in and under roof. The adjacent Plat House which they are also building - yes its a Camp House compound - is well under way with the framing going vertical. The Owner has over a dozen new photos for us which you can see in a photo browser after the jump. Some of the adaptations the Owner is making are obvious in these photos. You'll see an additional wall of windows on the side of the living room which greatly expands their view. And the roof slope which they have added to simplify collecting their rainwater is also easy to spot as well. You'll also see that the Owner has been welding up his own framing connectors for the Porch level posts and beams. This is an awesome hands on effort by the owner. Follow the link below to continue reading and more photos. Check out the Flickr set for this house where you can see all of the photos to date. And the photos are also part of theLamiDesign House Plan photo pool.

Nova Scotia Plat House mod

This is the start of another great Plat House project by Canadian architect Ross Macintosh. Ross provided the design services for the modification of the Plat House design on Prince Edward Island. This project will be located on Ballantynes Cove, Nova Scotia on a fantastic site overlooking the ocean. Ross has done a great job again expanding on the design themes in the Plat House design and adapting it to the local climate. see more images, follow the link below The site slopes quickly away from the level where you arrive and they have taken advantage of that to expand the area of the house with a daylight basement on the down-slope side. The second bedroom has been enlarged to make both bedrooms similar in size, gaining space from the utility room moved to the basement level. The stair down is located in an extension of the floor plan on the entry side of the house. This mod is similar to the PEI version where this added space allowed them to gain a third bedroom. I like the way the porch roof has shifted to one side in order to connect to the small out structure (sauna?). They have just begun the construction drawings so we won't see construction start for a little while, but stay tuned. Its going to be a great project.

Virginia Plat House - roof framed

New photos from the owner of the Virginia Plat House today. The framing of the roof is almost complete - the overhang at one side still needs to go in. These photos are from December, before xmas, so its likely that the roof is complete and the house sheathed by now. A few more photos are posted after the jump below, and of course all of the photos we have received can be seen at the flickr set for this project.

Letters from Sweden - Europe is different, Sweden is not, sort of..

Sorry for the delay in this series. I've been trying to figure out the best way to present these observations. Its time to look at the process in detail, but too much to cover in one entry, so how to break it up. I've decided that first we'll look at what goes on in the factory, and then on the site, and contrast both to prefab and site building practices in the US. But before we look at the studs and nail guns we have to consider their business model, and how it is different.

My correspondent from Sweden, Scott Hedges explained to me early on that there was more similar about the USA and Sweden than there was different. Sweden is bias towards suburban development, much as we do in the US. This is in contrast to other parts of Europe which tend towards more urban and village density for new development. Sweden like the US has the open space needed to develop housing in a suburban pattern, and like the US there is a relatively abundant timber resource for building houses of wood. So Sweden is like the US - they build suburban houses, in suburban neighborhoods. Yet the way they build the houses, the design of the houses they build are so different.
