Refurbishment Resource Efficiency Case Study: Lend Lease, Regent’s Place
Fit out of a central London
office block
Innovative reuse of materials and an emphasis on recycled content to combine
materials resource efficiency and improved aesthetics
Key business benefits
 99.7% waste diverted from landfill.
 Achieved construction water use 0.1m3 per £100k
construction spend.
 100% timber used was either reused from other
sources or FSC certified.
Project background
20 Triton Street is part of a fully managed 13-acre
development of Regent’s Place in Central London.
The estate comprises a mix of buildings including
offices, public spaces and a range of facilities including
a crèche, health and fitness club, supermarket and
restaurants. The phased completion of 10 and 20
Triton Street includes 140,000m2 of retail, office and
leisure space. The remainder of the Regent’s Place
development is ongoing and will grow to 190,000m2
on completion of the North East Quadrant which is
planned for mid-2013.
20 Triton Street is the European head office of Lend
Lease, who were also the main contractor for both 10
and 20 Triton Street. Lend Lease recently undertook a
full re-fit of the offices with a total project cost of
£15m. Work commenced in February 2011 and Lend
Lease moved into their offices in December 2011.
Business case
Lend Lease place sustainability at the heart of
company ethos, as well as providing leadership on the
subject of delivering resource-efficient construction
projects. Choosing Regent’s place as their European
head office provided Lend Lease with an opportunity
for showcasing these values and demonstrating the
potential for achieving cost savings and best practice
materials resource efficiency. The office was used as
‘laboratory’ to trial new concepts with the intention
that they can later be used in other work within the
property market.

Lend Lease also attached significant importance on the
health and wellbeing of employees as a key to future
productivity gains. There is emerging evidence to
suggest that people are more productive in
environments that have natural light, increased fresh
air and low toxicity. Improvements to space
configuration resulted in a high proportion of flexible
working areas that enable employees to work away
from their desks.
Embodied carbon
Water use
Building on the resource efficiency achieved during
construction, Lend Lease won a Green Apple Silver
Award for using a low carbon concrete mix on the
project, reducing the embodied carbon by around
5,000 tonnes when compared to standard options.
Water use was monitored on site: processes with the
most intensive requirements were identified and site
staff were encouraged to keep usage to a minimum.
As a result, the project achieved 0.1m3 per £100k of
construction spend.
Undertaking measures such as these helped
achieve overall site carbon emissions of 0.83kg/
CO2/Month/m2 during the re-fit, as calculated
from direct energy consumption.
Recycled content
Lend Lease achieved 25% recycled content (RC) by
value for the fit out. This was supported by a
procurement process which included mechanisms to
prioritise recycled materials as follows:
Scarcity & security
100% of all timber used throughout the fit out was
from reuse sources or FSC certified, which is in line
with Lend Lease’s corporate aspirations and ensured
sourcing from sustainably managed forests with full
chains of custody.
 Broadloom carpet by Bentley Prince Street with
10.03% post-consumer content.
 Fabric used in booth seating by Knoll Textiles with
80% RC.
 Bulletin boards were 100% PET of which 60% is
recycled material.
 External decking is ECO timber deck which is a
combination of sawdust and recycled plastic
 Use of recycled oak in kitchen areas.
Reuse
The design team re-used furniture from previous fit
outs and various other materials. This included flooring
throughout the building made from 100 year old
French Oak milled from recycled railway wagons.
Original carpets were lifted and given to charities so
that they can be reused in other buildings.
Durability
The carpet tiles used were chosen both for their
recycled content value and because they can be easily
replaced in high traffic areas, saving costs over time
and reducing waste associated with standard carpeting
solutions. Any carpet tiles that are replaced will be
recovered by the manufacturer, Quadrant Carpets and
reused in social enterprise projects.
Materials wastage
Lend Lease has an overall corporate target to reduce
the amount of construction waste going to landfill by
greater than 90%. The Regent’s Place project
generated 689.9m3 of waste which equates to 2.14m3
per £100k of project spend (construction). Of this,
they diverted a very impressive 99.7% from landfill.
Flexible working space
Life cycle considerations
Lend Lease delivered on their aspiration to improve
long term sustainability of the facilities by
implementing the following best practice features
alongside resource efficiency initiatives:
 Installing 4,000 plants (equivalent of 8 plants per
person) to improve indoor air quality. The plants
use coir as a more sustainable alternative to
standard soils.
 Building a 65m2 green roof and 2 habitat walls to
enhance the local wildlife habitat and allow
employees to enjoy fresh air outside.
 Installing secure parking for 50 cycles as well as
changing rooms, showers, 80 lockers, a bike repair
area and a dry cleaning service.
.
Lessons learnt
Post construction, Lend Lease carried out a
retrospective study of the supply chain for 10 and 20
Triton Street, exploring their ability to influence
materials and suppliers. 13 construction packages
were reviewed, representing 60% of the project’s
capital value. The results of this study will help to
inform procurement strategies and supply chain
expectations on future projects.
BREEAM assessment
Regent’s Place achieved a rating of ‘Excellent’ under
BREEAM Offices 2008. It is the first fit out project to
have achieved post-construction certification at this
level
