Existing home price as guide to new construction
Comments (31)I think the source of irriation is that OP is consistantly being misunderstood. I never got from any of his posts that he wants everyone here, plus every builder in his area to give him an exact cost analysis. What he said in the OP is what any of us has looked at who is wanting to build a home - can I afford to do this? Anthem - Ok, so I can't decide whether or not you are a contractor. I can tell from your posts you are, at worst, extremely knowledgeable, and are possibly a builder yourself. I still disagree with you about what you disagree with me :o). I am certainly NOT a professional, however, I have talked to a couple of builders locally and am in the process of GCing my own home. I realize that there are people out there who will try to get you to build them the taj mahal for a doublewide price, but not every homeowner is like that. Again, that is why I used words like rational, careful, thoughtful, etc. I suppose we are beating a dead horse, but Rob's plan is not exuberant, and I would even guess if he took it to a local builder who was worth his mettle, he has probably done something similar enough to get a rough estimate. I do get what you are saying about duplication being cheaper, that isn't rocket science. But also, in this market, at least in MY area, builders would rather work for someone with money in hand than build a spec every single time. I'm not saying it's an exact science, my experience - again, in this area - is that new home price can be a soft estimate for home building. Rob -- it's crazy for anyone to think you shouldn't know how much investment you are looking towards BEFORE you make a commitment. I suggest you take your ideas to a builder or two in your area and see if they have done anything similar. Or, just for starters, ask them what you can look to spend per sqft. That is not hard, there should be an average that they know off the top of their heads from recently finished projects. Now, this too can vary extensively but you get the idea... Sheesh, good luck! :o)...See MoreNew construction home completed - noise from the interstate :(
Comments (32)This may not be applicable, but it might be worth a try and i would be interested in what the pro's think. You could change the natural frequency of one glass panel by simply adding mass to it, like a stick on lead weight used in high end car wheels (a flat piece of lead with adhesive on it). If you put one of these on one of the glass panels you would change the natural frequency of that pane. Closer to the middle the better, but a heavier weight near a corner would do the same thing. If a sound guy could measure the natural frequency of a pane, you could actually "tune" the panes to offset the noise transmission. Just a thought....See MoreSoundproofing - My experience
Comments (3)Sounds great! I don't recall the details if you had a previous topic on this subject, but what type of windows do you have installed as the prime units? If they have a low-e coating on the glass, you are going to need to vent those storms in the warmer months to prevent excessive heat build up. Unfortunately that will pretty much negate the improvement in sound transmission. Additionally, you will want to check on the warranty of your prime units, as for some manufacturers the installation of a storm unit will void the warranty automatically. Don't mean to rain on your parade, hopefully your situation differs from those circumstances. Just thought that I would throw that out there before you invest in a house full of storms and end up with other problems....See MoreExterior sound abatement/wall construction insulation questions
Comments (13)the noise we want blocked is relatively high frequency and is mostly a window issue You got it! Windows are the weakest point--the typical window has an STC (Sound Transmission Class) rating of 20, about half that of a standard wall. You can buy windows with STC up to 50. As a mortgage manager/originator, I once inspected a home near an eight-lane arterial, sceptical of what I would find. Inside, it was quiet, no doubt largely due to the triple-pane soundproofing windows that the developer had been obliged to install on the street-side of the hundred or so homes in the area. For the walls, brick adds only about STC2, according to the figures from brickmaker Boral. Instead of standard fiberglass (fg )batts, you can use denser sound attenuating batts of fg or rock wool available from most manufacturers. As mentioned by others, you can also modify the framing and finishes to achieve greater STC. This link illustrates a number of different assemblies. https://www.certainteed.com/resources/Guide%20for%20Residential%20Sound%20Control.pdf For instance: With respect, 99% of builders are only going to give you anecdotal information on their own experience. You can do better yourself. Or get the input of an acoustics specialist. Just don't expect not to pay more to achieve your goal....See MoreA G
