Pin construction for house over water-reccomendations please

Postby falangsabai » Fri Dec 02, 2011 12:44 pm

We are building a 40' x 40' cement block home. We would like to have about 20% of the home built over an existing "bung" (pond) which is about 4 meters from bottom to home level. Before we start to interview construction teams I would appreciate any recommendations about construction method, pin size and cost. We are planing to build on a concrete pad with the land level pins set at about 3 meters depth. I am thinking we will need probably 16 pins in total, 3 or 4 of the pins would be in the water. Is this safe and advisable? Would it be much more expensive to build this way. Any and all help would be appreciated.

Take a look at mae on country home by robert k he has just about completed ""uneventfully""
but has built the way you are requesting partially in water
my comments may be wrong but never deliberately

Thank you for the referral. I found very useful information there.There are however some differences from my situation. His pond appears to be about 2 m while mine is 4m. His pins are only supporting a floor and sala roof, while mine will be supporting some walls as well. I do plan to consult with a professional regarding final pin design but would like to hear as many ideas as possible first. :D

There are several ways to deal with it
Take a look at the waffle slab depicted by developer 3d the idea being build a "solid slab raft"
that spreads the load across the pond bottom (drain the pond)

You could consider hammering in piles this could involve draining the pond piling it then your foundation slab/pad on pond bottom with a poured colum supporting the house

Somewhere i saw this done using a digger for retaining a river embankment & deck they pushed a steel pin down creating a hole in the right location then pulled out the pin and replaced it with a normal H section pile also the pile was hamered with the bucket i am pretty sure that was a guy/specialist set up to do that specifically

Or probably more to your taste would be a cantilever huge concrete beams cast deliberately to support the section over the pond this is a feasable way to go but you are relying on the land side of the house to suport the overhang so beefed up footings on the land side and bigger steel bigger beams to support the floating section but the beams are cast deliberately as part of the walls so it retains the ilusion of hanging ""suprisingly"" i am pretty sure Fred put a picture of a house like this in his beautiful homes thread and i get the feeling if you follow the info you can find the original which gives info on how it was done with the beam layout i will have a looksee later as its time to rest (old and knackered ) this route will involve a talented (and brave) engineer for the calculations but you will have to go minimum weight with the end walls (maybe a high % glass) sound interesting though

like a bridge over troubled waters ... Da da la da da...

Like 'why would anyone want to build over water'?
Sorry i just dont get it.
Tonight my sleep was arrested due to 1 lousy mosey sketter. So it it out with bug light fan on #3.
My biggest battle is keeping the screen doors closed.
I tell wife if i want to live in the wild i save loads o doe by just pitching a tent. But please respect me & respect the money i spent here by keeping the damm screen doors closed!
+=#*
and someone wishes to build a house over mosey sketter infested waters???

Fallangsabi i hope this one helps its not where i thought it was so it took a re read of Fred1k,s thread this thing has a 13 meter overhang
you can actually see the steel frame through the windows (diagonals) so the options are a similar desigh :roll: or concrete beams and higher windows allowing for substantial beams
but it is faily straightforward to do although challenging

More info Google Balancing Barn Sufolk if you hit lucky one of the sites has picture,s of the frame :roll:

Could you post pics of your build site?
I thought I was wrong once but I was mistaken.
