PROJECT PLAYERS

PROJECT SCOPE

JamesHyatt Studio has been involved with the design o the landscape

and site work or The Peninsula Beverly Hills since its original construction

Aside rom creating memorable landscapes and outdoor rooms, completing

this ve-star luxury hotel was a technical challenge, as all outdoor areas

are on-structure. Even with this constraint, lush gardens surround the

bungalow-style villa suites with private patios and a roo garden terrace

dressed with cabanas and a swimming pool ofering magnicent views

Recently, JamesHyatt Studio completed the renovation o the hotel’s

pool deck, upgrading the original concrete pavement with an elegant

mosaic-tiled surace. As the Peninsula looks to make major landscape

renovations to keep up with competition in the area, JamesHyatt Studio

is assisting with a redesign o Luxury Suite 335, the arrival courtyard and

ountain and overall landscape improvements and maintenance guidelines

The pool deck at The Peninsula Beverly Hills is an intensive rootop garden. Green walls surround private cabanas ofering

extra shade or hotel guests.

Green roos and roo gardens soten the harshness and isolation o cities and suburbs and play an

important role in the development o LEED®-certied buildings. There are three types o rootop gardens

A GREEN ROOF OFFERS MORE THAN JUST A PRETTY VIEW 

According to a report published by the American Society o Landscape Architects, the initial cost o greening

your roo is higher than conventional roong systems, but a green roo can pay or itsel over time. Green

roos extend the liespan o the roo membrane signicantly by protecting it rom sunlight and temperature

variations. On-structure gardens capture and utilize stormwater as their primary source o irrigation while

plants clean and lter the excess runof. Green roos and roo gardens cool the planet and protect against the

urban heat island efect, reducing roo temperatures by as much as 80 degrees Fahrenheit in warmer climates

GREEN ROOF SPECTRUM 

•  Intensive: an accessible, park-like roo garden with conventional trees and plants requiring irrigation and maintenance.

•  Extensive: a traditional rootop blanket o sedum or sod requiring little maintenance.

•  Semi-Intensive: a combination o both.

GREEN YOUR ROOF WITH OPTIONS 

BEFORE DECIDING ON A GREEN ROOF / ROOFTOP GARDEN, CONSIDER THE FOLLOWING QUESTIONS 

• What kind o roong system is currently in place and how old is it?

• What is the load-bearing rating o the roo?

• Is the roo area to be used or service unctions such as window washing, etc.?

Your answers to these questions will determine the most cost-efective approach to selecting and installing

a green roo system or rootop garden. ValleyCrest Design Group, our network o Landscape Architecture

studios, can assist in guiding the selection process and preparation o plans to drive the installation

process. ValleyCrest Landscape Development is a member o the U. S. Green Building Council and employs
