As a follow up to previous Blog re: this topic, below is a re-cap overview of our line item construction cost analysis requested of our Consulting services:
New home ‘overall requirements’ are different and more extensive, than when we ‘add on’ to the existing structure and therefore an increase in price.
Some of the additional items required involve significant site work, especially if there is a slope involved.
For instance, typically multiple retaining walls will be required to shore up aspects of the site, for the planned footprint of the new home/detached buildings/driveway/stairs/recreation areas etc. to be accommodated for at the proper elevations.
Also additional drainage work, above and below grade, will be required throughout the site. This would involve concrete culverts, underground drain pipes, terraced grades and usually retention ponds/storm water planters.
Around the lower part of the home, waterproofing the exterior walls from the bottom of the footings to above finish grade level, will be needed.
Regarding the building/structure itself, new two story concrete and rebar footings will be required, after excavating work; in lieu of using existing footings and typically adding some ‘pads’ for posts to bear on.
As well, new first floor/second floor/roof framing with up to date structural connections will be required by code.
Adjunct new materials (i.e. windows, doors, drywall, flooring, plumbing and electrical fixtures, tile work, paint, etc.) and equipment (i.e. hvac units/ducting, water heaters, kitchen appliances, etc.) and low voltage wiring, cabinetry, fire sprinkler system, closet work, etc., needs to be factored into this budget.
And all of the above is after demolition of the old existing home and other structures are taken off the site ($60,000+), if we’re not starting with raw land.
All in all, it will cost 50% or more to build your new home; but it will be exactly the way you want it to be and virtually maintenance-free with the latest technology implemented into the materials, systems and equipment.
