Professional WorksThe following works are a selection of the projects inwhich I have collaborated during my professionalcareer.
Proyectos Parque Hábitat c.a. is an architecture firm located in Caracas Venezuela that develops urban - architectonic projects. It specializes in large low cost residential projects. It also develops commercial projects and remodeling projects as well. Thew mission of this firm is to develop residential complexes in which open public space is a key factor in order for the inhabitants to expand beyond their dwells. Sports courts, pools, small plazas, are some of the strategies adopted in order to achieve this objective. The following are the projects in which I have been participated.Proyectos yParque Hábitat c.a.
Residential development [Parque Hábitat Castillejo]This project is located in a suburb east from the city ofCaracas.This is a “government protected” residential develop-ment built by a private developer. In total it has 198 de-tached units, and was finished in 2009. Because it is a“social housing” project, the major challenge of thisproject was to develop a residential unit that couldmeet with the expense power of the market target. Inorder to address this challenge, the house is designedto be constructed in two phases. The first phase is com-posed by the gorund floor, in which there are two bed-rooms, two full bathrooms, kitchen, dinner and livingroom. One side of the unit, to the front is reserved tobuild a parking space for one car. The second phase hasmultiple variations. On the first place it can be devel-oped a a separate one bedroom apartment, with anindependent acces. The other two variations contem-plate the expansion of the house, which aims to buildtwo more bedrooms (growing from a two to a four bed-room unit) or the second option is to create a smallhome-office/studio space.About the urban design, this project aims to create aseries of small parks in which the residents can performleisure activities. Also there are two sport facilities forthe residents. Phase 1 Phase 2
Mixed use development [Parque Hábitat El Encantado]This development is located in a suburb close to the city of Caracas. Theproject combines a commercial (Southern part of the site) and a residen-tial site to the north. The residential development has 480 apartmentunits distributed in 22 buildings. The centre of the project was envisagedto be a large open, green and community space with parks, sports facili-ties and other amenities. For project for the commercial site is a smallshopping centre. This building designed to accomodate basic services forthe surrounding communities.To meet with the stakeholders expectations, for this project there weredeveloped two different types of buildings within the same structure andfacades. The bigest challenge was to increase the number of apartmentsthat could be built in the same building. This led to design more efficientunits that could meet the local building standards, as well as the marketdemand.The first layout, type A, has four units per level, with three different typesof apartments. One, two or three bedroom apartments, from 55m2 to85m2 approximately. The second layout, type B, has six units per level. Itonly has two kind of units, one and two bedroom apartments around57m2 per unit. The reason to develop a building under this concept wasto improve the flexibility of the building and project’s profit. In order to beable to develop such as a flexible building it was necessary to carefullystudy how the different systems (electricity, drinking water, waste-water)should be designed and built, in order to avoid interferences as well as toimprove the systems performance in order to reduce the building’s costs.This strategy of improving the flexibility of the building’s layout andmaximizing the number of apartments that could be sold, turned out toexceed the client’s expectations.

Multi dwelling housing building [Parque Hábitat el Milagro]This project is located in the eastern city of Maracaibo in Venezuela. Thiscity has the highests temeratures averages during the year. This led totake particular atention to improve the solar protection on the facades.The location of the city of Maracaibo is in the north of Venezuela, next to alarge salt water lake. The building’s site is located close to the west coastof the lake. That was an advantage due to the average wind directioncomes from the East, which means that in most part of the year the windbrings within it cool air from the water mass.The building is twelve stories high. The lower two first levels weredesigned to work as a private parking lot. On top of this there is a centralplaza, which is the main public space of the building. On the same level,to the east, there is a terrace that complements the building’s communi-tary spaces. From this level up, there are ten levels with twenty eight unitsper level, to sum up a total of two hundred eighty units, divided in fiveunit types.This project is in the final phase of it’s construction.
Parque Hábitat El Ingenio.Due to the size, 980 dwellings, this residential development is designed tobe built in four stages.In order to achieve the goal of building more than 750 dwellings in thesame project, there was a lot of time researching, modeling, prototypingand evaluating different approaches to optimize the housing unit. Theresult of this work was an important improvement of the building system.The material waste was reduced, and the construction process wassystematize to increase the building speed.There are two types of units. The first one is arround the 65m2 in a splitlevel unit. The ground level hosts the public spaces of the house, while inthe upper level are the two bedrooms and one bathroom. The secondunit type is about 95m2 splited in thre levels. As well as the first type theground level hosts the kitchen, dinner room and living room, while thetwo upper levels hosts four bedrooms and two bathrooms.The houses are aligned in a wat that each unit has two entrences. Oneside goes to a lane, which is conected to the centre park, while the otherones conects with the inner street and the parking space.

Multi dwelling housing building [Caraballeda Suites]This project is located in the in the town of Caraballeda, which is down tothe coast about 30 km from the city of Caracas. This makes it one of thebest weekend get away location for the city dwellers.The project was design to meet with two different kind of buyers. On thefirst place, it had to meet with the people who were looking for a leisureproperty to spend weekends and hollydays. Also it had to take intoaccount a share of the market which involves the local inhabitants whorather commute to the city and live close to the coast. In order to do so,the project was conceived with units flexible enough to meet with bothdemands. Also it offers amenities as a marina, which is also available tothe general public. The building is ten stories high. The lower two first levels were designedto work as a private parking lot. The third level wors as a central plaza withthe main amenities and public spaces of the building. From this level up,there are 7 levels with a total of 48 units, and the last level alocates 28split level apartments, to sum a total of 76 apartments.

Business Centre [Banco Occidental de Descuento]This project is located in the in the city of Maturin, in the East side ofVenezuela. This city is know to be the headquartes of different oil compa-nyes which works in this area.The owner of the site is a private bank. Their expectations were to build abusiness centre that could accomodate their regional offices, as well assome commercial-office space to lease, a convention centre and a com-mercial use ground level.The orientation of the building site only allows the development of abuilding that is alingned in a north-south direction, which means that themain facades will be exposed to the east and west sun all year long. Inorder to address this issue, the eastern and western facades should betreated according to their own conditions in order to improve the comfortinside the building.Following are presented two proposals to the project.
H2G Arquitectos c.a. is an architecture firm located in Caracas Venezuela that develops residential and commercial architecture projects. This studio was founded in 2005 after I obtained my degree as Bachelor in Architecture in Venezuela. The studio specializes in residential projects (single & Multi Familiar). It also has participated in interior renovations of commercial spaces, such as offices and stores. The following are the projects developed by this su- tudio.H2G Arquitectos c.a.

Concert Hall Rehabilitation.This project was a proposal to renovate a old cinema theatre and transform it into a concert hall for the “Sistema Nacional de Orquestas Juveniles e Infantilesde Venezuela”. Unfortunately this project was only developed to the preliminary stage.The main idea of this rehabilitation was to build a concert hall next to the offices of the Foundation for small concerts and plays. For this was necessary tocreate a lobby capable of adaptate to different kind of events. As the lobby the concert hall itself, has kind of the same principle, to adapt to diferent kind ofevents, from a single violin play to an orchestra concert. It was necessary to create all the backstage spaces as well as the service spaces needed to perfomthese kind of events.Lower Level Upper Level[lobby - Bar - Offices] [Concert Hall - Backstage] Concert hall service spaces Concert Hall Stage Backstage Offices + Bar [Lobby service spaces] Lobby Section - [Proposal]
Academic WorksThe following presentation is a selection of projects de-veloped at an academic level.
The objective aims to rehabilitate an existing building taking into consideration energy efficiency concepts as well as passive bioclimatic design strategies. To be ableto do this it is necessary separate the project in differnt stages.First it is necessary to evaluate the work place. This analysis allows to understand how the area works and which are their inhabitants needs. The indicators whichcan be studied are buildings accesibility improvement, increase vegetated areas, analyze motorized traffic and acces to public transportation. Besides this Ürbanperformance”indicators, it is also necesary to studi the work place with a climatic perspective. In this case indicators such as the sun-path and the buildings shadowsaffect the public space and the other near bildings, as well as how prevailing winds run trough the open spaces and how does they collaborate with the natural ventila-tion of the dwelling units. Rainfall volumes are very important, due to in Madrid rainfall levels are not high. Finally, and to end this stage, an Bioclimatis Analysistrough the Olgiay Climatic Diagram is performed to see which pasive design strategies should be used while the project is developed.After ending with the analysis stage and having collected all the data, we proceed to select a building to develop the project.master degree project.
Location This project is located in the periferic neig- borhood of San Blas, Madrid. This kind of developments was part of one of the many urban plans that the city devel- oped back in the seventee’s. The objective of these plans was to promote low-cost housing projects. Upper Level
THE FACADE. 1 building. 4 visions. This project has as its point of origin a personal concern which is that trough the last three decades the facade of the buildings have become the result of the functional distribution of the space instead of being an element to be designed as well. Throughout history, the facade appart of having a functional roll (protection from the enviroment) it has had a meaning rol. Through it the different stages and movements of architecture history are represented. An historic timeline allow us to understand the significative value of the facade through time, and at the same time to question how it is being used in the present. “... Is it really the result of the functional distribution of spaces or it can be a part to be thinked and de- signed with the same intensity?...” This work looks foward to investigate the value of the facade at the present time. To achieve this, an observa- tion of different buildings types and the stablishment of different categories, plus an analisys of these building types to discover how the facade is being used in each and everyone of the cases. This observation and analysis process will results in the creation of four categories: the Walkthrough facade, the Digital-cromatic facade, the transformation facade and the Appearence facade. Each one of this catego- ries will be taken into consideration at the design stage of the proyect. In order to develop the building, I decided to continue with the last semester project. This left an area for future development. Instead of following the convetional design process, I decided to take the facade as the point of origin. As the facade design evolves, there appear diferent hints, which will be used to define the possible use of the internal spaces, in other words, the quality of the space will be determined by the behaviour of the facade and the type of inside - outside relation that i would determine.bachelor degree project.

URBAN DESIGN. Building the public space.The parameters that rule the open space are verydiferent from the ones which prevail in the interior.The pedestrians, the vehicules, the flows (with thierdensities and intensities) are some off the factors totake into consideration at the moment to design.To begin with this projetc, first is necesary to anal-ize the work place. In this case it is going to be avery important urban corridor in the city of Caracas,Venezuela. The objective of this analysis is to showa series of indicators in order to adress the effort ina more efficient way. After the anlysis, one of theidentifided placeces will be chosen to develop apublic space, according to the needs of the place.The Boulevard del Cafetal” is an important roadaxys within the city of Caracas. This axys conectsmany residential zones with the rest of the city.The main needs of it are: Recover the walking con-dition of the boulevard, provide the same number ofof roadlanes along the whole route.The public space to be developed will be a plaza.This plaza will be compesed by three parts, a pedes-trian border, a low intensity zone and a high inten-sity zone. The pedestrian border consist in theinclusion of the sidewalk into the plaza, at thismoment the sidewalk becomes part of the plazawithout loosing it’s movement space condition. Thelow intensity zone is conformed by a vegetal border,which as a park allows the public to read, rest, playgames, etc. The high intensity zone is a skate park.It is located in the center of the plaza and it sepa-rates from the the rest of plaza at the moment it’sdepresed. Another part to be taken into consider-ation is that a zone of the site is left empty. Thiszone will be left ti be developed with the construc-tion of a building. This one could be a cultural or acomercial building.
