The begining of Marmol Radziner

The story of how they got here from there is a familiar one: Two young idealists meet at school (California Polytechnic at San Luis Obispo), toil at separate firms, and then join forces in 1989. But there the script veers off into the unfamiliar, unglamorous territory of design/build. According to Marmol and Radziner, their choice was obvious. “We realized the loss of control we had from not building our own projects,” says Marmol, who worked on construction sites in the San Francisco Bay area as a teenager. “Design/build is a historic process,” adds L.A. native Radziner. “Before the early 1900s, the two disciplines used to be more intertwined. We’re going back to the old style.” So Marmol obtained his contractor’s license, and the pair amassed a portfolio of small remodels and additions. They took care to market themselves as architects who could also build, so potential clients wouldn’t confuse them with the “builder offering design services” model that’s more typical of design/build.

Hawkesbury residence

At the base of the wanaka valley, the ‘hawkesbury residence’ by los angeles-based marmol radziner overlooks the rolling farmland of mt barker, new zealand. oriented with an elongated elevation towards the north, the dwelling is protected by a deep roof eave to block the strong sun of the southern hemisphere while framing the distant alpine peaks. approaching the homestead,the structure is encompassed by and recedes into the barren hillside beyond. the linear configuration and shallow footprint allows sweeping mountain views from all of the interior rooms which are framed by the roofline and cedar deck.

Lautner‘s Garcia Residence

In order to maintain the distinguishing features – the memorable curved roof over the living spaces, colored glass panels, and v-shaped supports that anchor the home into its green hillside site – the architects performed in-depth research, which took several months. for example, to find the closest match to the original terrazzo marble no longer mined, lava rock was procured to renew chimney in the living room and the pantry area. the bedrooms saw the most change, as their fixtures and designs have been updated to accommodate a contemporary lifestyle, without compromising the original intention of the space.
