Introduction Cumbre Mar is a condominium development of thirteen units designed to get the maximum density with the lowest impact on the land and the context. The design began when there wasn’t any other building in the sorrounding plots, only nature and views. PROJECT TEAM: Location: Punta Leona, Puntarenas, Costa Rica Footprint Area: 2.340sqm Land Area: 1.850sqm Covered Area: 710sqm Architectural Design: Aarcano Arquitectura S.A.

A Design brief and site considerations In a hillside opposite to the sea and facing sunset, there had to be organized the maximun number of condo units that had to have similar conditions in views, accessibility and built area. An important part of the design brief was to determine the size of the units and the market segment these condos were going to reach. Base on the land area and local regulations, market studies and site qualities we had to determined if the solution was going to be one big building block ore single separate units. We ended with an â&#x20AC;&#x2DC;in betweenâ&#x20AC;&#x2122; solution: the creation of clusters with two or three units to merge them into small scale modules that will reduce the impact on the land and on the neighborhood. The modules are separated between each other to improve the ventilation and simultaneously to allow the visual access towards the sea. These separations generate semi private access to common areas, social zones and to each unit.

Diagrams to study zoning and use of land . The idea of separation in mudules also allows a better accessibility and parking distribution with few infrastructure needed. As we were able to located the maximum density permited, we needed to guarantee two parking spaces to each condo unit. The result is 13 units organized in five modules.

710sqm of covered area = 39%

Each one of the thirteen units is organized in three modules: 2 modules of 4x8mts and one of 4x12mts. The first two accommodate the bedrooms and the biggest module locates the social area. Due to the topography, the units are in different height related to the street access.

The proposal for the project is conceptualized by understanding the pattern of rocks from the zone: fragmented configuration, porosity, hierarchy in the organization. This configuration allows different types of organisms to proliferate and live, protects them and gives shelter. In this way, the units are defined as regular volumes that are cut by random elements that generate spaces of scattering, quietness and socialization.

B Location

Located in Puntarenas, Costa Rica, the site is part of a new development of the condominium â&#x20AC;&#x153;Altos de Leonamarâ&#x20AC;?. The plot has a spectacular view to the Pacific Ocean and to the sunset, and is sorrounded by a natural context of enourmous trees that are home of a variety of birds, including lapas and tucanos.

SITE LAYOUT

LOCAL AND VERNACULAR BUILDING STYLES Architecture in the pacific area of the country is mainly an attemp to create protection from the hot climate and to create social interaction based on living outside the buildings. Balconies and corridors are more important than courtyards. The necessity of shadow and cross ventilation gives character, as well the sloped roofs with large roof extensions to protect fron heavy rains happening during the year. The oppenings are controlled in order not to allow the heat to enter the saces. The materials are allways local, with a preference in wood and concrete.

C Architecture and use of space Each module contains two or three units. The diagram below shows the organization of a module of three units. Each one of the thirteen units is organized in three geometric areas: 2 areas of 4x8mts and one of 4x12mts. The first two accommodate the bedrooms and the biggest module locates the social area. Due to the topography, the units are in different height related to the street access.

D Appearance & Finish A very simple pallet of material was implement in the design. Concrete blocks and concrete structure are the base for the structural integrity, glass and wood are used as surfaces that link the inside with the outside. The surrounding vegetation is also a material for the architecture. Soon the walls, gardens and common spaces will be covered by different type of local plants.

E Sustainability, Energy conservation, Environmental use of renewable energy, Innovation The project is design to collect rain water and use it for the swimming pool and gardening areas. Waste water is treated to avoid water contamination and all toilets and bath appliances are low consumption to secure the use of fresh water. The project has implemented many passive design strategies, such as cross ventilation, roof hot air ventilation chambers, sun protection for all main openings to avoid over heat. The construction was based on minimal terraces to avoid big movements of the soil and small scale concrete walls to contain the terrain.

ÂŠ Juan Carlos Sanabria

Build locally: Concrete is produced in Costa Rica. The idea is not to import the majority of the construction materials. The wood used is as well from the area. Local people was hired to build the project, no high tech was needed neither big scale machinery. The project was designed to adapt to the topography: For reasons of functionality and integration, it was opted to organize the main entrance and the garage based on the street where car transit was possible. Its fragmentation, necessary due to the steep topography, transforms the whole into a composition of small linked and interconnected volumes, creating an unevenness that allows for a more rational and optimized use of the lot. 22 | 23

F Safety & Security

Each unit has a direct contact with the exterior thanks to the separation between modules and the topographic adaptation. Open spaces for reunion are located in key areas of the complex. An anti-seismic structural design was implemented due to the high risk of earthquakes in the area, and also because the proximity of the cliff. Concrete colums and beams with the sufficient capacity are the main structure of each four story building. The fire prevention is based on cabinets and is been supplied by the main condominium development, and access to all areas is guaranteed.
