2. Richard George Rogers, (23 July 1933 – 18
December 2021) was a British-Italian
architect noted for
his modernist and functionalist designs
in high-tech architecture.
He was a senior partner at Rogers Stirk
Harbor + Partners, previously known as the
Richard Rogers Partnership, until June 2020.
Rogers was perhaps best known for his work
on the Pompidou Centre in Paris, the Lloyd's
building and Millennium Dome, both in
London, the Senedd building, in Cardiff, and
the European Court of Human Rights
building, in Strasbourg.
He was awarded the RIBA Gold Medal,
the Thomas Jefferson Medal, the
RIBA Stirling Prize, the Minerva Medal, and
the Pritzker Prize

3. Design Philosophy
• He had a very environmental
conception of designs.
• The notion of social integration
is one of the other most
important points of the Richard
Rogers’ architectural concept.
• According to him social
problems can find solutions in
the construction of “compact
cities with multiple centers”.
• Richard Rogers’ architectural
philosophy’s topics are legible,
transparent, lightweight,
systems, urban, public and green

4. Lloyd's building, London, UK
The Lloyd’s Building is the home of the insurance
institution Lloyd’s of London, and is located at 1, Lime
street, in the City of London.
The building was built between 1978 and 1986.
It is a leading example of High Tech architecture in
which the services for the building, such as ducts and
lifts, are located on the exterior to maximize space in
the interior.
The building was innovative in having its services
such as staircases, lifts, electrical power conduits and
water pipes on the outside, leaving an uncluttered
space inside.
The building consists of three towers, each with
their own service tower, which surround a central 60-
metre high atrium that houses the main Underwriting
Room and is naturally lit by a barrel- vaulted glass
roof that took its inspiration from Joseph Paxman’s
Crystal Palace.

5. • The basic of the building is that of a large atrium,
surmounted by steel and glass arched roof, surrounded
by galleries (12 levels of them on the north side) which
contain the bulk of the underwriting space and a
variable amount of lettable space, depending on the
changing accommodation need of the Lloyd's market
itself.
• The floors were constructed on reinforced concrete
columns on a 10.8x 18 meter grid. The load is
transferred between the columns and the floor beams
by means of a pre-casted bracket. Precast ‘yokes’ cast
into inverted U-beam transmit the loads of the floor grid
to the perimeter columns via the brackets.
• The great columns, both the exterior of the building
and within the atrium, stand proud of the cladding,
increasing the highly articulated ‘Gothic’ effects of
Lloyds. External cross-braces are actually made of steel
tube concrete grid open to view.
• The Lloyd’s of London building consists of three main
towers-each attached to their own service tower-that
are concentrically oriented around a 60 meter atrium at
the heart of the building. Each floor acts as a gallery
overlooking the atrium; however, only the first four
floors are open to the atrium whereas the rest are
enclosed by glass panels.

6. •The entire building is
wrapped in stainless steel
giving the building a high-
tech, almost postmodern,
aesthetic. The streamlined
façade juxtaposed to the
mechanical and service
functions on the exterior
evoke the technological
advances of its
construction, as well as
express the building’s main
focus on functionality.

7. •The towers form a flexible framework for the ventilation plant,
lifts, service risers and lavatories (all the 33 lavatory units were
manufactured and fitted out) attached to them. Four towers carry
major plant - rooms, with mains services running vertically down
the towers and connected into each level of the building. The
largest services duct contained the air- conditioning, with lesser
duct for water, drains, power and electronics Main services running
vertically down the towers.
•The Lloyds Building, consisting of twelve stories to the north,
stepping down to six stories to the south, sunlight penetration thus
utilized.
• the Incorporation of the atrium.
•The atrium was a key feature in the reduction of the loads coming
from lighting.
•The atrium increases in volume and surface area as it progresses
toward the south.
•The office levels increase as the progress northward allowing a
large surface area for diffused light coming from the north. A
significant amount of natural lighting reaching down into "The
Room" demonstrates the success in the design of the atrium.
•Furthermore, every location in the building is located within 7
meters from a natural source of light.

8. A significant amount of natural lighting
reaching down into ground floor
demonstrates the success in the design
of the atrium.

12. Inmos Microprocessor Factory, Newport, UK
• The Inmos microprocessor factory, also known as the Inmos factory, is a building in
Newport, Wales, UK which was originally built as a microprocessor fabrication plant for
Inmos.
• Construction began in 1980 and was completed by 1982.
• The architects of the award-winning high-tech building were the Richard Rogers
Partnership.
• The technical requirements of the brief from Inmos called for an area dedicated to the
microchip production with controlled clinical conditions protected from dust and
vibration, while offering more open offices and a staff canteen under the same roof.

13. • the Inmos Microprocessor Factory is a highly-flexible single-storey steel structure that was
conceived as a prefabricated kit of parts that could be constructed anywhere.
• It contains a microchip factory, is identified by the outward expression of its structure and
building services that help keep its interiors column free.
• In the case of the factory, this emanates from nine blue- painted towers made from
tubular steel that are positioned along the centre of its roof.
• The final structure consists of 16 equal-sized bays, each measuring 13 by 36 meters, which
were built one by one to form a rectilinear building.
• These bays are positioned either side of a central spine, which runs the length of the
building like an internal street, and divides it into two wings.

14. Plan

15. • The corridor measures 7.2 meters in width and is 106 meters long, designed by Rogers to
be wide enough for vending machines, telephones, seating and planted areas.
• On the north side of the spine, the building contains a "clean" area for microchip
production. Meanwhile the south side has a "dirty" ancillary area, which includes the offices
and a restaurant. One bay in the middle is used as a landscaped courtyard for workers.
• To ensure all these bays are left uninterrupted and column-free for flexibility, the Inmos
Microprocessor Factory's structure and building services are all positioned above the
building on its roof.

16. • The building's exoskeleton is built of nine blue steel towers that are positioned in line
with the central corridor and are attached to 40-meter-long trusses that extend either
side from it. These trusses are supported by tension rods.
• The towers enclose a series of double-storey service pods and plant rooms, from which
all ductwork feeds out across the building's flat roof and into the ceilings of the bays.
• All of the Inmos Microprocessor Factory's external walls were designed to be
customizable – based on a system of standardized mullions that can be fitted with infills
ranging from single or double glazing to translucent or opaque panels.
