It is 265-acre displays North America. The grounds were planned and designed by Amer-ica’s first landscape ar-chitect, Frederick Law Olmsted. Begun in 1872, It is one of the crown jewels that comprise Boston’s “Emerald Necklace.”

consists of an 1,100-acre (4.5 km2) chain of parks linked by parkways and water-ways in Boston and Brook-line, Massachusetts. Some links of the Emerald Necklace not only offer an opportunity for recreation in a wooded envi-ronment, but are also ecologi-cally important urban wilds that provide nesting places for migratory birds and im-prove the air quality of the city.

The Emerald Necklace:

The Arboretum is privately endowed as a department of Harvard University.It was given a thousand-year lease on the property, and the University, as trustee, is directly responsible for the de-velopment, maintenance, and operation of the Arboretum.

The Arnold Arboretum: The Outdoor classroomand Vine Trellises :

It is located in the Arnold Arboretum and designed by Maryann Thompson Architects. The Pavilion structure serves as an outdoor class-room and a place ofrepose.

The Harvard University:

Diagram:The Arboretum is within easy walking distance from the surroundings.The grounds are open free of charge to the public from sunrise to sunset 365 days of the year.Average yearly rainfall is 43.63 inches; average snowfall, 40.2 inches. Monthly mean temperature is 51.5 °F.

Site Analysis:

The main program of the site is the outdoor classroom and the vine trellises located at the north side.The woody collections are around the program including the hardy trees, evergreen areas, shurbs and vines.

The exquisitely crafted stone walls that form a base for thestructure connect it to the terraces below and the hills and trees in the background. A freestanding stone wall forms the western edge of the pavilion, providing a barrier to the traffi c noise on nearby Center Street and the Jamaica Way. They forms the garden terraces using traditional construction methods that date backcenturies and characterizeRichardson’s stone walls sotypical of Boston.

Two sections of wood and metal roof fl oat overhead with the same slightly skewed shapes as the planting beds. The slot of space between the two roofs allows shafts of southern sun and views of the sky to penetrate to the terrace below. The shaft of light adds richness to the texture of the pavilion, acting as an additional textured material. Stainless steel railings with polished wood caps provide crisp contrast to the earth and stone thatsurround them.

The south edge of the pavilion structure is lined with vine sup-ports that allows for the southern sun to throw a dappled light onto the pavilion’s stone fl oor. The pa-vilion’s columns and beams rise from the earth with a natural economy of means, while its sys-tem of struts and cables suggests an architectural interpretation of the tendrils of climbing vines. The geometry of the column lines shift in plan and section, at once veiling the entrance it opens the space dramatically out toward the gardens.

The plan of the new gardens, designed by Reed I Hilder-brand, is organic in form and spatially rich, evoking both the botanical traditions of French parterre gardens and the intricate patterns found in nature, such as the branching of trees or the veined confi gurations of insect wings.

The Pavilion Structure:

The Pavilion structure serves as an out-door classroom and a place ofrepose. The structure is a focal point within the overall composition of the gardens. Visitors moving experiences a spatial sequence of discovery and the expansiveness of the central lawn.

The Pavilion structure is comprised of brushed stainless steel beams and col-umns that support a roof of lead-coated copper over natural cedar tongue and grove. The materiality of the pavilion evokes the metal garden structures of the late 19th century.

Qianyi’s Refl ection:It shows how the designers work with the structure of the site. From the history side, it is trying to evoke vistors’memories about the old garden style. From the nature side, it works toprovide a view direction for people who come to this site.

Related to my own design, I have the same concept about how to provide different views for people standing out of site and in the site.

To improve my work, I will focus on how to make a connec-tion between these views. The materials used in the Pavilion have nature things like wood. It also has the modern materials like mental. However,there is a balance between them. For example, the mental columns connects the wood top and stone fl oor but with the pre-prent their textures.The things I learn is how to let the different parts of sturcture with different materials come together as a whole thing.
