4Client LongchampLongchamp, a French company based in Paris manufactures and markets fine leather goods including handbags, luggage and accessories.The company was founded in 1948 and opened it’s first factory in 1956.The name “Longchamp” is a tribute to a famous Parisian Horse racing track.Longchamp is a 240 million dollar business employing 800 people in the production of leather products.In 2003 British designer, Thomas Heatherwick, designed Longchamp’s best selling handbag, “The Zip Bag”.Longchamp products are sold in 200 stores across the United States. The SoHo store, profiled in this presentation, is Longchamp’s 100th store worldwide.
5Thomas Heatherwick Studio DesignerThomas Heatherwick StudioThomas Heatherwick was trained as a designer at Manchester Metropolitan University and at the Royal College of Art in London.He is a Royal Designer for Industry, a Senior Fellow of the Royal College of Art, and holds an Honorary Doctorate from Sheffield Hallam University.Thomas Heatherwick Studio was established in 1994 “to make unique design projects happen”.The studio and workshop is located in Kings Cross, London and employs 35 architects and engineers.Heatherwick Studio’s work has been recognized in many areas including Architecture, Sculpture, Urban Infrastructure, Product Design, and Exhibition Design.As the designer of Longchamp’s popular “Zipper bag”, Thomas Heatherwick Studio was the ideal choice to design Longchamp’s U.S. flagship store in SoHo.
6Project General Information 150 tons of steel were used in the overall projectConstruction time ,000 man-hoursOverall cost of project - $12,000,000Height of atrium ’Cumulative strength of magnetsin display features tons(enough to support the weight of 10 N.Y.C. Taxi cabs)Specific to Steel Landscape:Cost of steel landscape - $2,000,000.Construction time ,750 man hrs.(steel landscape only)Thickness of steel plates ¼”Weight tonsDimensions - 27’ x 46‘ x 60’Number of steel “ribbons”Total length of ribbons ’Thickness of rubber strips - 3/16” + 1/16” glueTotal length of natural rubber strips ’(equal to the width of Central Park)Rendering by Thomas Heatherwick Studio
7F o r m s Project Context Site address | 128 – 132 Spring Street (between Wooster & Greene) in SoHo, NYCUpfit of an existing historical 1936 commercial buildingwhich required hearings before the NYC LandmarksPreservation Commission.The building once housed an architect’s office.The building’s modest presence on the street gives littleindication of the major retail space inside.The site is urban and therefore constricted, makingdelivery of large steel components difficult.“site is on the dark side of the street with very little spaceat street level” Thomas HeatherwickF o r m s

9Project MaterialsMaterials draw customers from the entrance into the store and up to the second floor.30 ribbons of steel cascade through the core.Floor areas are finished with red maple boards.The building’s original brick walls and cast iron columns are exposed.The ceiling is made from laminated sheets of ash veneer.Display fixtures are fabricated from a variety of widths pale American ash laminated panels.Openings in the ceiling reveal the original textures of the building and the current MEP systems.
10Design Concept A “Theater for Retail”. A major piece of Architecture behind an unassumingfacade.A topography of walkways, landings, and steps thatdraw the visitor from the entrance at the ground floorto the second floor.Longchamp wanted a unique architectural ensembleto be appreciated as one of a kind.“If we have no store at the ground floor, then everyonehas to go up”. Thomas HeatherwickUpper floors with windows have much more light thanif the retail area were located at ground level.Atrium and skylights flood the steel river with light.“Like insects, people are attracted to light”.Thomas Heatherwick

13F o r m s Design Structural Stress DistributionDesign StructuralRetrofitting an existing building (1930s era) with a design this innovative made the structural engineering of the project both unusual and challenging.Structural Interventions on the existing building:Addition of third floorRepositioning of elevator & egress stairs.Punching shaft through floors to allow for stairs, atrium, and skylight.New foundation to support 55 ton staircase.Major structural reinforcement throughout building.Live Loads: Roof & Monumental Stair psf1st & 2nd Floors psfMaximum Stress Allowed : Fu = 0.75 FyDynamic Vibration Analysis of the monumental stair design tested both 36 KSI and 50 KSI steel. The results revealed no difference in performance so for economy 36 KSI was used.Brick WallLateral SupportVertical SupportSupport DistributionF o r m s
14Design Egress Plan Second Floor Plan Green StreetSpring StreetSecond Floor PlanExisting36” StairThe Monumental Stair is exempt from Fire Protection since there are two other exit stairways.The site contained an existing 36” wide egress stair.A second fire rated (2 hour), 44” wide, egress stairwas added.Accessibility to the upper floors is provided by a new elevator enclosed in a two hour fire rated envelope.Maximum actual travel distance of design is 88’ - 5”88’-5”44’New44” Stair
15F o r m s F o r m s Design Display Units The display shelves which line the perimeter of the sales area share the sensibility of the steel stair in that they appear as ribbons of material cut of, but not detached from, the whole.The forms which become the display shelves are softly folded down from the thick ceiling panel and then in turn the individual shelves appear as layers which have progressively delaminated from that thickness of the vertical forms .The voids left by the “peeling down” of the display units reveal the services (MEP) located in the space above.The ceiling and display shelves were fabricated by laminating multiple layers of wood, with the final surface being a fine veneer of natural colored American ash.F o r m sF o r m s
16F o r m s Design Balustrade “The stairway is enclosed by an impossibly etherial glass balustrade, that shimmers like transparent fabric.” Architectural ReviewThe preliminary design was rigid in character and appeared to be an attempt not to compete with the highly innovative stair or to provide a counter point to its curves.Heatherwick Studio was not satisfied with this design and spent the next year experimenting with alternate designs and materials.The result is a balustrade that is as noteworthy as the stair it protects.The balustrade is a series of hand-formed panels fashioned from a thermoplastic referred to as PETG (polyethylene terephthalate glycol). This plastic is generally used for the manufacture of airplane windsheilds and headlight reflectors.True to the nature of hand crafting, each of the 46 panels is unique.Steel uprights welded to the steel stair support both the panels and a very simple steel hand rail.F o r m s
17F o r m s Steel Landscape Physical Properties Uninterrupted forward and upward circulation.1 ¼” steel thick rolled steel plates form 30 sinuous ribbons.Stair rises a height of 17’- 5” to the second floor with two landings.Tread depth ¾ “ | Riser height - 7”Weight - 55 tonsFabrication time months3/16” thick natural rubber in a warm burnt ochre color is applied to tread (top & bottom since both are exposed).High-powered magnets attach sculptural display forms anywhere on steel “stairs” to display leather goods.The steel handrail is enclosed by thermoplastic panels.F o r m s
18F o r m s Steel Landscape Fabrication Cutting the Steel Curved steel templates of the tread profile were cut using a water jet.A water jet uses a jewel nozzle with a 0.004” ” diameter orifice to pin point a highly pressurized water spray on the material to be cut.The pressure is typically between ,000 psi(30 times the pressure of a power washer)A water jet system uses a supersonic erosion process in which stream velocity, not pressure cuts the material.A water jet never gets dull & cannot overheat.Abrasives are often added to pure water to cut tougher materials.The mixture leaves the nozzle at a speed greater that 900 mph.With a 30 HP pump, an abrasive jet can cut ½” thick Titanium at a rate of 7” per min.F o r m s

20Steel Landscape Fabrication Bending the Steel The Press Break causes the plate to curl up.Steel Landscape Fabrication Bending the SteelThe steel members were incrementally bent to meet pre-determined profiles.The incremental bending was accomplished using a hydraulic press break.All markings on the steel were eventually ground off .Chalk marks at regular intervals determinewhere the Press Break will bend the plate.The amount of curl is determined by the frequency of Press Break compressions.

25F o r m s Steel Landscape Assembly After the stair was fitted in the shop it was dismantled and shipped in segments to the site.All rigging fasteners and connections were shop-welded.The size of the segments was determined prior to the fabrication according to the installation site’s clearance dimensions.Since no horizontal span was involved, the segment parallel to the wall was fabricated from thinner (1/2”) steel plate.F o r m s
