About the Interior Designer

Diane Murphy – “Visual design has always been in my life” says Diane Murphy.  Formally trained as jewelry designer in the fashion industry and later as an art director in the advertising industry, Ms. Murphy made the transition to interior design 25 years ago when she designed and built her first home in Harrison NY. Her most recent home in Rye NY went through numerous renovations and changes as her family grew and her own personal style evolved. “Living near the Long Island Sound has always been an inspiration for classic coastal design elements, Diane explained.  “Even more inspiring are found objects – repurposing and reusing is always present – I never pass up roadside treasures. But it is the little details that give me the most pleasure – the accessories, bath hardware, nooks and hooks – all these details are like jewelry for your house.”

Connecticut Net Zero ICF Home Wins Another Award

2 March 2015

An award winning ICF net-zero home was named one of the most innovative projects in the country. The Shore Road Project, built by Murphy Brothers Contracting, in Greenwich, Connecticut, recently was recognized as one of the most innovative projects in the country at the ICF Builder Awards. 


The ICF Builder Awards is an international competition designed to showcase the advantages of building with Insulated Concrete Forms, commonly called ICFs. The Shore Road Project was named best in the "Small Residential" division.


This is the third major "builders award" presented to this home, which was designed as an Old Greenwich coastal colonial-style custom home by area architect Rex Gedney. Lois Arena of Steven Winter Associates served as the all-important project energy consultant. 


Mamaroneck Builder Creates Green Dream Home

13 December 2014

I have owned a construction business in Westchester County for over 35 years with my brother Sean. When my wife Diane and I finally had the opportunity to build our own custom home, we decided very quickly that it was going to be green and it was going to be beautiful.


The house would be under 3,000 square feet with four bedrooms, and an open first-floor plan that would satisfy our desire to entertain both large and small groups of friends and family.


We decided to build our home in a coastal colonial style, framing the outside walls with insulated concrete forms — or ICFs as they are called — styrofoam blocks that stack like Legos, then are filled with concrete.


For years I've used ICFs for foundation walls like many residential general contractors. But I knew intuitively that I could build a better home with ICF exterior walls, if only I could convince a client and his architect to design it.


Since this was my house, half the challenge was overcome.

Innovative Old Greenwich Home is Up and Conserving

26 June 2014

When Diane and Chris Murphy moved to their waterfront colonial home at 15 Shore Road in Old Greenwich, their first instinct was: out with the stick-built home and in with the concrete-structured, environmentally conscious abode. Chris Murphy, co-owner and president of Murphy Brothers Contracting, hired his own company to rebuild his 2,700-square-foot home using Styrofoam and concrete — adding eco-friendly details such as a dual-fuel heat pump and electricity-producing shingles, the first to be used in Fairfield County.


Old Greenwich Home Makes Electricity in a New Way

8 May 2014

The waterfront colonial rising on Shore Road in Old Greenwich — already notable for its foam-block design — now features another first. According to Murphy Brothers Contracting, which is building the 2,700-square-foot home, the roof is now covered with electricity-producing shingles, the first such installation in Fairfield County. Manufacturer Dow sent a representative to mark the occasion.

Mamaroneck Firm Helps Build a Cooler Home

31 January 2014

“We’ve been wanting to do a house with it for a while,” says Chris Murphy, co-owner and president of Murphy Brothers Contracting Inc. in Mamaroneck. He says he learned of it at a home building convention in Las Vegas and through his architect Ray Gedney of Rye. So when Murphy, who has been in the construction business for 35 years, found himself poised to build a new home for him and his wife, Diane, he knew he wanted to use what is known as ICF.

Building, Block by Block

17 January 2014

he white walls of the home at 15 Shore Road in Old Greenwich are rising quickly as contractors stack one block on the other, building an entire home’s exterior out of Styrofoam the way a child would build a fort from Legos.


   It’s a curious sight, the kind Greenwich has seen only a couple times in the past, if at all. But while it may look a bit strange as the large foam bricks reach two stories above the ground, the idea of building a house from Styrofoam makes some real sense, the builders say.
