The quality I like seems to be closer to $450 + (current homes under construction in LAH).
Hope this helps.
It depends on the lot (size and slope) and what you wish to build. Is the house on sewer or septic? Will it include a basement? What is the MDA and FAR of the lot? What type of finishes do you want? How do you define "fairly good materials?" Are you building for your own use or to build to sell? Have you spoke with an architect and/or local builder about what you would like? Do you have the property or will you need to procure it? I have too many questions that need to be answered before I can give you a good idea on costs. Please provide more details.
Good luck. Owen Halliday
High end materials and construction methods: $$250-$350/square foot
These number ranges are based on replacement costs I've seen recently in appraisals done on properties in the town.
