Gast Architects

Business Description
Founded in San Francisco in 1980, Gast Architects is an eleven-person, service-oriented practice specializing in custom residential homes and renovations, including the sensitive restoration and adaptation of historic properties. We offer comprehensive architectural services and take pride in the close working relationships we develop with our clients in responding to their needs, taste, budget and schedule, while maintaining architectural design excellence. Sustainable design strategies are integral to the design process, and several on our team are experienced LEED Accredited Professionals.

Our projects range in scope from the development of large country properties and inner city whole house renovations to more modest additions to and remodeling of existing housing in styles from warm modern to traditional. We enjoy, and are skilled at, working with the limitations and opportunities inherent in renovating or adding to existing structures. Our long-term relationships with contractors, craftspeople and consultants strengthen the trust and effective team communication necessary for producing superior results.

Having practiced in the Bay Area for decades, we know the local Planning and Building agencies and their staffs, and how to work with them to secure code interpretations before problems arise. We have represented our clients successfully before commissions, design review panels and appeal boards, and are adept at moving our projects through the approvals maze.

Suave, you really don't Need to prep your soil. There are soooo many things you can do that won't exhaust you physically or take too much time. I am a YouTube Junkie. :o You can find so many Videos on Permaculture, Hugelkultur, Back to Eden gardening with woodchips, no-till, etc. If you want to kill your grass, you can just lay down newspaper and cardboard, then cover it with soil. Our entire Yard is a dirt mess right now. We just rented a digger and ripped out the roots from 12 large trees and a rediculous number of overgrown bushes. I used the Wood from some of the trees to start the hugelbed, but first had hubby dig me a trench maybe 45 to 50 cm deep. It is now about a meter tall and I am slowly adding dirt to it. My Goal is to incorporate permaculture practices and hugelkultur into my landscape so I don't have to work as hard. I am also against paying for water for the garden, hence getting a rainwater tank. I hope to have at least 200 different kinds of plants, herbs, flowers, trees, berries and vegetables growing in the yard. The more variety, the fewer pests. There are some great Forums for this sort of Thing. is a great one. I would LOVE to go off-grid, but we are in town and there is no way hubby is moving. Instead, I will continue to make every effort in reducing our carbon footprint. We have a telescoping pool cover being installed in a couple of weeks. It will act as a green house and heat the water for us, Keep it cleaner, prevent most Evaporation and eliminate our Need to drain the pool every autumn. The manufacturer is a Swiss Company as well, so fewer fossil fuels will be used to get it to us. Win Win. We are also going to be installing a retaining wall with Gabion baskets. For those, the Company is based in the UK, but have them made in Europe, so still not too far away. The rocks for the baskets will either come from our property (I am collecting them now) or from a local quarry. I think that living here in Europe, we are at an Advantage when it Comes to People being concious of where things come from. Even our milk at the local Coop is regional. Still, I try to get what I can at the farmers market or grow my own. There were some great suggestions from other Posters on reducing our Need by making our homes better insulated, turning off lights, etc before we take the leap of something like solar or wind, but I would still like to be able to rely on my own rather than what is brought in. It may not be more cost effective, but it is probably better for our future.

We live in California and are currently looking into a company where you do not have to buy or lease the panels. They own and maintain the panels completely, constantly monitoring them so as to make sure they are producing enough to meet the minimum production they promised in your contract. There is zero out of pocket to get everything going, and in exchange for that you can expect a 3.5% increase in Kwh cost each year. That in contrast to the average 6.7% annual increase with SCE, not to mention their proposed 9.7% increase proposal on the verge of going through and another 16.7% increase they're trying to push! It seems to be a great option for those without the ability to fork out the upfront costs and/or those who don't plan to stay in their home longer than another 7-10 years, both of which apply to us. They also have an option where you pay only about $3000 up front to defer installation costs, and then you have no increases in cost ever. But of course then it takes a few years before you start comng out ahead because of the initial investment. Still a great low cost option though.
