Making a House That Will Last for Centuries?

tcyun asks: "The intro text from kaisyain's review brought up a thought that has been floating around in my head as I am a new home-owner. If one wanted to design a home that would last for hundreds of years, what would one have to do? I, and many of my friends, have recently/ purchased homes. As with all homes, some things are in good shape, others are not. Many items are the fault of initial design, many are due to poor upkeep and repairs. Looking around, it is possible to have a home last for hundreds of years (my family's ancestral home is about 400 years old and there are castles in Europe that are older). If one wanted to build/modify a home, what would one need to do to make sure that the home would still be standing, and usable, hundreds of years from now?" M : Wired suggests going underground.

"A few elements come to mind: structural integrity, usability, reparability, ease of upkeep, physical location (geology and neighborhood), technology, and aesthetics.

  • Structural integrity: Rock lasts a long time, but has a variety of draw backs. Concrete (poured or cinder block) foundations are common where I live but wood is still the material used for most of the structure. Should steel cross-beams be considered for parts of the structure? I have heard good things about laminated/engineered wood.

  • Technology: Folks on Slashdot have talked about wiring homes with cat-5/7/x and installing empty conduit 'just in case.' Is this really useful with the proliferation of wireless? Would it be more useful if a crawlspace was made available between the ceiling and the attic so that any type of ducting/wiring could be run into a room? Should all rooms have access to a central column through which wiring, plumbing and ducting were run?

  • Usability: I have a small house with a small, combined living-family-dining room. I am fairly sure that 50 years ago the designers were not laying out the space to take into account book shelves, a large television, stereo cabinet, gaming consoles, and more in addition to a couch, chair and dining table. Simply making the room larger is one option, but cavernous space is not necessarily good for usability. What would be a good floor plan and how might different sized rooms be distributed to be useful over time for multiple purposes? Would it need a bathroom? (joke)

  • Reparability: the previous homeowners made a number of DIY 'improvements' which are nice, until one needs to make a repair. Many items are installed in ways where the only option is to remove entire installations. What types of modular improvements can be made that allow for easy repair/replacement over time as needs change?

  • Location: How would one choose where to build a home that would last for hundreds of years? Do you pick an existing neighborhood, space that is at the edge of a town/city or somewhere further out? Does one pick a neighborhood that has been economically/geologically/stable/safe over the longer term even if it is not in great shape at the moment. At first glance, cities in the United States like San Francisco, Detroit, Chicago, Pittsburgh have all gone through 10-20 years spells of nastiness, but have been fairly stable cities at the macro level for a hundred years.

  • Aesthetics: Does one simply design/architect and deal with the fact that it will variously become attractive/unattractive over time?

And to complicate matters, how different are the options if one imposes a budget for initial construction (depending on your own idea of what a realistic budget is)."

      The big problem with steel studs will be corrosion.
      They come electroplated or zinc dipped. some are punched and formed _after_ plating, leaving unprotected edges. You then go and poke holes in them with screws, and leave corrosion points. If you go with steel, use bolts in pre-primed holes and paint over the bolt heads.

      If you go with concrete, use galvanized rebar. You'll shit a kidney when you see the cost, but it's the best thing since, well, rebar. Bar corrosion and the ensuing spalling is what will eventually weaken your foundation.

    I have lived in several North American houses >100 years old, and I was sure that most of them would last another 100 with proper maintenance. So it is possible.

    However, a problem you will face is climate control and ventilation. Those 1800s houses were drafty, had huge non-living-space attics, and had poor energy efficiency. After thinking about it for a while, and visiting friends' tract mansions that smell of mold and rot 18 months after completion, I am convinced that the excess (and energy-consuming) ventilation through those old houses is a bit part of why they last so long.

    Unfortunatley it is no longer acceptable to have your bedroom go to 110 deg.F in the summer and 38 deg.F + draft in the winter! So were I designing a new house to last, I would add a very large heat exchanger and the necessary vents, fans, smoke detectors, dampers, etc. to force-draft a good amount of air through the house. This would probably mean a duct system separate from the air conditioner (I would probably use radiant floor heating). And also a lot of motors, fans, controls, etc - so buy spare parts for 20 years down the road.

    Your idea of an insulated equipment space between the top floor and attic is a good one - possibly you would want to put the heat exchanger there. And I would go ahead and wire for Cat6 and CATV, since technologies like that don't go away as fast as people think. But use conduit so you can change your mind on the media later.

Today we have reinforced concrete, which is even stronger than anything the Romans had. Also, this will make it prohibitively expensive to tear your house down if anyone gets any bright ideas about turning your property into a parking lot in a hundred years.

    Step 2: Use concrete for interior walls, floors, well, basically everything. What's the first thing to go in old houses? The roof. And, when it does, water gets into the house and the whole structure rots. A concrete roof will keep water out, which is the most important thing if you want the house to last.

    Step 3: Don't use glass for the windows. You can get a 4x8 sheet of inch-thick lexan or plexiglass, which is bulletproof by the way, for 175 bucks down on Canal Street in NYC. It's an extremely resilient material.

    Step 4: Don't build the electric and etc into the walls. Design the house so that everything is retrofit, i.e. bolted onto the surface. That way you can always strip it out and replace it later. Note that you can't do this with plumbing, but no plan is perfect. Go for PVC pipes there; at least they won't rust.

    Step 5: Paint EVERYTHING with a polymer-based paint to waterproof it.

    Step 6: make sure the house sits at the base (or top) of a cliff or some other construction-inconvenient location. Then plant LOTS of oak trees all over the place. Within fifty years they'll turn into a nice forest. This has a couple of benefits:

    A) if anyone tries to build on your property, the tree huggers will come out and Hayduke their machinery. They'll also spike the trees, which makes it reeeeeeeally tough to chainsaw them down safely.

    B) Even if the local town board figures out how to get around the environmentalists, it'll cost 'em a fortune to knock down all those trees and make room for a wrecking crane to go for the house. They'll give up and go somewhere else.

    Step 7: Cultivate the area around the house into a wetland, then make sure every environmentalist in the area is aware that it's there. Then, get the EPA in to declare it a wetland. This is way easier than you might think. It makes it just about impossible for anyone to build anything there ever again.

    STEP 8, the MOST IMPORTANT STEP: Put the whole property into some kind of legal trust, so that you don't even really own it anymore and no one can sue you for it. Then, set up the trust so that it just passes along to your children, and so on. Your descendents will have use of the house forever, basically, but won't be able to sell it. In the process, make sure there's enough money in the trust to pay the taxes for at least the foreseeable future.

    My parents house is a 19th century farmhouse in Ireland. The walls are unshaped stone (just the faces are finished)and mortar. They are three feet, (yes 1 meter) thick. There is a 3 feet thick dividing wall in the center of the house running between the back wall and the front wall.

    The roof beams are old ships masts and a lot of the other timbers were ships timbers.

    The foundation is on bedrock.

    It's survived a gas cooker explosion (which took out 2 windows and the kitchen cabinets, but the floors and the walls never moved), several huge storms over the last century and a lot of floods.

    Building houses that way today does cost a fortune. For a start you can't get good timber anymore - most timber is kiln dried and doesn't seem to age as well as the timber that was stored for 20 or 30 years to dry naturally.

    It's also hard to find a builder who knows the principle of dry stone building. Most older Irish homes were built in the same style as drystone walls, except that mortar was also used.

  19. geez by Tumbleweed · · Score: 4, Interesting

    Okay, I love stone as much or more than the next guy, but it's hardly necessary to build a house out of stone to get into the multi-hundred lifespan range. There are lots of houses in New England that are stick-frame homes with wooden clapboard siding that are >200 years old.

    There are numerous threats to a house's longevity:

    1) Weather
    2) Pests (insects, mice, etc.)
    3) insufficient maintenance
    4) Problems such as earthslides, earthquakes, settling, tree roots damaging foundations, etc.

    This is off the top of my pointy head, so I'm sure there are categories I'm not thinking of right now.

    Okay, so we know that you can get a stick-frame, non-stone house to last for multiple hundreds of years. How to PLAN for that is another matter.

    First, take the weather and your local area into account. Prone to earthquakes? In a flood plain? Loose soil? Soil that drains poorly? On a hillside? Design accordingly! Many of these are foundation design issues and can be designed around. I'd stay away from the flood plain, though.

    Next, once you've got your design TYPE planned, make sure your builder is doing to use appropriate engineering to achieve the design requirements. These include new types of roofing materials, roofing support design (big issue in Hurricane-areas - make sure your roof SUPPORTS can take it). Make sure your roofing system can 'breathe' if that's what it needs. The roofing material needs to be matched to the correct roof support system - cheap builders don't care, but this is what can cause massive roofing problems a few decades down the road, depending on weather in your area. Make sure your soil drains properly. Make sure your foundation is sealed properly. Make sure your windows are correctly installed (and skylights are even more problematic), and installed correctly for YOUR type of wall/roof system. Make sure your house is designed properly for your site - what type of sun/wind/rain do you get in that area? Make sure your window & skylight placement is proper. On the coast? Make sure higher salt content & moisture content in the air is taken into account for ALL materials used. Moisture-resistent drywall. Wood that comes in contact with concrete/stone/earth needs to be treated properly. Don't use wood shingles if you've ever heard of 'fire'. Live in a forest area that is prone to fires? Design accordingly (have a swimming pool - backup water source for dousing house down).

    Maintenance. Learn what all the systems in your house would require, and make sure you've got the wherewithall to make that happen. Maintenance costs money, so build that into your accounting. Making your house's internal environment have a fairly consistent temperature/humidity level will go a long way to making wood and drywall last much longer. If your roof needs work, get it done RIGHT AWAY. Same thing for plumbing, electrical, and foundation systems. These are your critical priority systems to maintain, as they can impact everything else in very bad (expen$ive) ways. If your architect & builder are smart, they can minimize the amount of plumbing needed (designing house to that, say, kitchen, bathrooms, etc. share as many walls as possible. A good builder can make things like 'wet walls' (remember the Matrix?) where service people can get access to normally hidden things like plumbing, etc. Having to bust through a drywall to get to hidden plumbing really blows.

    Make sure everything is vented properly (bathrooms, oven hoods, etc.) - that helps make things more livable. Make sure you spend the money for the good windows that tilt in so you can easily clean things and INSPECT them. Getting cheap stuff that isn't easily accessible is probably not a good idea in the long run.

    Flooring - radiantly heat that floor! Very nice technology.

    Zone heating/cooling - a great idea, but having vastly differing temperatures in adjoining rooms makes me nervous. I've seen no anecdotal evidence of this being a problem, though houses with zone heating/cooling

  22. Building a structure that lasts by civad · · Score: 5, Insightful

    Some of the criteria mentioned by the author set me thinking: and here is what I think might be useful in building a house that lasts:
    a. Structural integrity
    Structures made from rocks tend to last longer. In fact, most of the ancient buildings or structures were made of rock. Ditto for Medeival castles (and not_just_the_ones_in_Europe). So, looking at the past, rock should be your first choice. But is it the only one? I don't think so.
    Reinforced concrete *could* be an option. However, concrete is a very treacherous substance Also, if one lives in area that experiences heavy rainfall, concrete might not be a good choice. Moisture/ rainwater can seep through the voids in concrete and can corrode the reinforcement. The cost of waterproofing might be huge.
    Bricks. Lots of them. The thicker the brickwall, the longer it might last. But then how many people would want a wall say 4 feet thick?
    Timber: In principle, well-cured timber should last for a long time. For e.g the pillars that support the dykes/ docks in many older European cities.
    b. Technology
    That is an interesting criterion. TV screens are getting bigger, computer monitors are getting thinner. So, the amount of space required for each of these "Display Units" is changing. Similarly, cell phones are a commonplace, so theoretically, telephone conduits/sockets are not necessary. It is difficult to predict what the appliances/ applications in the future would be like.
    c. Usability
    What do you, the owner/habitant of the structure plan to use the building for? If you plan to stay there for a LONG time ( and I mean till ripe old age) start thinking of having ramps instead of staircases. Or escalators. Similarly, the bedrooms should be on the ground floor (or first floor as some people call it). How many children are you planning to have? Do you plan to convert the building to a museum/public library after your death? THat will decide how much of usable space you will need to provide in the house. Remember, a group of people need more space to move through a room than a single person.
    d. Reparability
    Concrete repairs are expensive. Rock masonry repairs are difficult and expensive (I am speaking in genral) Timber *might* be cheaper to maintain.
    Again by meintenance I am assuming normal maintenance (painting/waterproofing, etc.)
    e. Location
    As far away from Human habitat as possible. The Pyramids/ castles/ Great Wall of China....were they in the cities/ suburbs????
    f. Aesthetics:
    I am not the aesthetics type. Personally, I believe that functionality is superior to looks. What is considered beautiful or appealing today might not be considered the same in the future. ("In the 60's in England one could have bad teeth and still be considered sexy"...Austin Powers Int'l Man of Mystery if I am not mistaken)
    **Remember: at the end of the day, it is RESOURCES that will decide the fate of the structure. Some kings spent decades building monuments. Some dynasties spent centuries building walls.....They could do so because they had resources. In terms of land, labor, money, material, time and many more.

    Modern buildings, with very few exceptions, aren't designed to last for hundreds of years. Architects, developers and builders design and build for the short term, not for the long term. The materials they choose to work with aren't designed to last for centuries simply because cities, and hence buildings, evolve over time - what's needed and what's fashionable today will be useless and outdated in only a couple of decades from now.

    The proof of this is around us - buildings erected in the 60s and 70s are being pulled down all the time, to make way for more "modern", "practical" and "aesthetic" developments. This is especially true of commercial buildings but it also applies to residential structures too.

    Modern building design is nothing like Victorian building design. The Victorians constructed brick buildings, because brick was the best material available to them. As a result, they couldn't safely build more than four or five storeys - beyond that a building would not be able to support its own weight. They also (for the most part) didn't have any means of transporting goods and people up and down easily - lifts/elevators didn't really take off in a big way until the turn of the 20th century.

    It was only when the means to work steel effectively, to shape it as required, was developed that modern building design took off. Steel being lighter and stronger than brick allowed architects to design taller, more spacious buildings and coupled with the use of lifts/elevators, it allowed them to break the ceiling barrier that previously existed. Once they started to work with steel, they quickly were able to go very high, very quickly, hence the rapid development of skyscrapers almost overnight in New York and other cities.

    But I'm digressing from my main point: The reason why buildings don't last is because, generally they're designed with the knowledge that they'll be obsolete within their designers' lifetimes.

The new techniques of using rebar to tie the pad and rehinforcing top beam together is great. Here's a good book on it.

    We're planning on having a rammed earth ground floor with a timber framed second story. The ground floor is going to be designed for additions to be added on as needed (large doorways in exterior walls).

    For interior use, we're going to use a manifold system that will pipe water to where ever it's to be used. You can think of it as two hubs, one hot, one cold and flexible pcv/vinal lines that run, in the ceiling, from the hub to the faucet. This gives you flexibility in placing sinks and such or even repurposing rooms. For sewage, that'll run under the floor. This'll be accessable from the basement.

    Raised conduit will only look like a "cross between a prison cell and a boiler room" if you don't make an effort to make it otherwise.
    Let's say that instead you put in an inch deep baseboard covering a two inch deep recessed channel. The baseboard, since it will be unusually visible, will be oak or other material chosen to look pretty and age well. A matched crown molding with tapered base fills it in. If a third horizontal is done in the form of a chair rail then there is plenty of room to run anything that we have reason to know to foresee.
    Since many of the approaches mentioned here would work best with nine foot or taller ceilings, all of this should be nicely in proportion. If, as I suggest further down, window seats, shelving, and other such things are built in out of matching materials, then the room should actually look quite pretty.

    A few things to keep in mind:
    -All conduit should be attached with brass or other ornamental nuts and bolts. No nails, no hidden connections. This reduces the risk of some nitwit cutting into the baseboard or other conduit because they can't see that it was meant to be removable. Best case scenario would be to have a few small places in the house where vertical conduits have small glass windows so that people can see that stuff is running inside.
    -Verticals could be made to look mock-tudor or some other style that typically has visible beams and supports.
    -"Spiking" the inside of the surfacing with thin, long ceramic rods might be a good idea. This, again, is meant to reduce the odds of some ignorant future person just starting to slash away. Nothing like hitting industrial ceramic in what seems to be wood to get a person's attention.

I brushed off the dirt, sat up, and just then I saw a rainbow in the western sky. I knew then that I was master of the mountain. This is where I would build a home for my family.
