" It's always fun to watch the contractor and the architect when they first meet have you got any questions about her design. Mr. du Bob this 310 insulated system. They really work with -- before in down. The main question I had was will do you just fill these styrofoam blocks of concrete in them."
" And I'm very excited about the system because it seems so strong in fact it's filled with rebar is both vertically and horizontally and then pumped full of concrete. The styrofoam forms stay in place afterwards for insulation purposes."
" And then you have to parched with Stucco over the of the stars -- your exterior finish on top of that and makes a lot of sense to especially on western wall here in south Florida you're gaining so much solar heat all afternoon. That it makes a lot of sense to get insulation and so that's basically the way the whole addition the three walls will be built with these three -- forms. What about the roof the the only other question I had problems over here where the two routes intersect. The flashing and that's going to be you know. But given that."
" We have thought about it and it is detail that we do have to draw or in effect what we have is an existing suburban house with the kind of gently. Slope -- the children. Dry your hair. And he had write ups and -- Our new kitchen at this glorious beautiful clear story right -- what effect come down this way. And intersect with the existing roof and that's your area of concern. Which we will drop period."
" You know that's that's funny is that if the sheets where the roof let's say you've got an existing roof like that ditching water in this direction. And a new roof coming like that ditching water in the opposite direction that point is we could have water coming into the house. And we'll be very careful that you have to provide an architectural detail maybe some custom flashing -- correct that. Boy and this house looks like a fortress now is this typical construction. The says typical Bob Iran except for the arches and some custom features that is the -- is in the foyer and in the entrance now what about the the foundation is -- a basement at a big foundation. Well there's really a foundation. There isn't putting that I'd like to show you over here and there is no basement -- there is no basement. Over here Bob with the footings and his. It's a little bit hard to see because normally these footings -- in the ground essentially dig -- where the floating into the ground around the perimeter of the whole thing your building that's right whole house continuous footing with the two and number five reinforcing bars reinforcing rods yet. And then you just lay up your concrete blocks staggered joints you have to fill them with concrete you know they can remain Apollo. And is this necessary concrete this is obviously poured concrete at the corners at every corner you have to have a poured concrete columns with the affordable five rebar. And they go up and they tie into. A -- being with just a continuous being around the perimeter of the house and that also reinforced with steel so you're creating almost a cage of wire and concrete in your building in with concrete block. I noticed that you've got. Poured concrete. Bob the windows as well in the -- basis. What about the roof structure. I want think it probably see that better in the -- problem with. Is the roof stick built. I know Bob there are pre fabricated trusses which are made specifically for that now. So it's a truss system and it basically arrives it's put on there and you just but the plywood back over it. That's right and in this case from -- it's a metal. Pieces to accommodate drywall they're spaced specifically to receive the drywall that's interesting instead of wood would trappings you've got you down. -- you tie the whole thing down onto the concrete walls. Well over here we have hurricane straps and show you here. They had get screwed into the time being with some screws on this on this and then -- up on the they get nailed to the truck. And they wrap over the property trust or even though the weight of the roof is sitting down on the wall still. If you have a pressure situation and hurricane for example were once the blow the roof off. These -- strap it down absolutely needs primarily for uplift this is the two story house in this kind of second -- structure -- will come -- let me show you. Comes just concrete everywhere here -- wow. Look at this not the entire second floor there's a concrete slab. That's right. And is that all floating -- could I'd take out all these stud walls and just have one huge open space you could one of the advantages as it's the concrete slab may be a little more cost up front but there's lot's been and it has Bob one is of course flexibility in future remodeling. The other thing is and along with the of these steel studs is that termites don't like Corian in -- we don't have to worry about termite damage to courses fireproof as well. As well but you mentioned coughed as -- a lot of money that it. To the cost of construction. Now it's really not that much. When you look at the trade off of having to install conventional wood Warrington. Flooring in and actually putting sheathing down because this -- informative Warren you're done and the metal stud partitions. Are not load bearing in this tough they're not hearing the way to the floor not at all but they could be used in a traditional situation where they would have to -- load right. Yes they could steel studs. Of course have been used in commercial world for many many years and they're now. Increasing in popularity in the residential. Market and their recyclable and their site."
