The site is located on
the western coast of the Tróia, specifically in the development Soltróia, this
is an area occupied by a mid-high segment of the population, whose homes are
set up as second homes.It is an area of beach
overlooking the Atlantic Ocean, with some pine
trees and diverse vegetation characteristic of the dunes.
Being an area of rare
beauty, little known, and obey the constraints imposed by the regulation, were
the reasons for the choice.Following
the topography of the site, the house follows the development of a dune,
indicating the way to the beach.
Partially buried in the
dune, which will "invade" the covers, House and dune arise in
continuity.The idea of developing
housing along the dune geometry resulted in a "Y", allowing the
distinction between public and private areas.This
leads to a body half-buried in the dune, corresponding to the area and social
services, and other more private body, integrating the area of the bedrooms.
The interior presents
itself continuous, so as to avoid the limitations imposed by closed
compartments, giving fluidity and transparency to live.
From the lobby to the
ladder that takes place around the social bathroom, giving access to the upper
floor, consisting of a socially privileged home - the living room - and the
office.The living room, with
large areas of openings on opposite walls, is crossed by the landscape, and
punctuated by the volume of the fireplace.The
reversal of the "Y" is sufficient to create a very reserved area of
the office.
The upper floor is
surmounted by a mezzanine on the dining room, ground floor, benefiting from
double ceiling height.From this room, the space
is bifurcated, which break down in the area of rooms and bathrooms, bath
support, and areas of the kitchen and dining. The
bedrooms are accessed by a corridor, with rhythmic openings and wall cabinets.The kitchen and dining bounding up the dining room by the volume of
another fireplace, and present are marked by a continuous balcony that extends
the outdoor patio. Along the front half-buried, still on the ground floor, are
distributed the service areas, comprising the areas of treatment and storage of
clothes, as well as access to the bathroom and social facilities.The concept used to
generate the proposal takes advantage of its surroundings, taking ownership of
the dune.Thus, the earth shifted
to bury part of the house, is used to coat the roof and there is no waste in
earthmoving.
With regard to solar
orientation of housing, the facade oriented to the northeast has mall openings,
serving only to illuminate the inside occasionally.The windows on the rooms and office oriented to the southwest, and span
the living room of the facade facing to the south, provide a better insulation
during the winter, having driven shutters to control the surplus during the
summer. The development of the proposal along the dune rise to bury the facade facing
to the south at the ground floor, helping to maintain a comfortable indoor
temperature in summer, in winter, the windows located near the ceiling,
ensuring the entry of sunlight.
The positioning of the
openings on opposite walls in different areas of housing make natural
cross-ventilation, producing cooling without using mechanical means in the
summer, and ensuring the renewal of the indoor air in winter.
There is a ventilated “trombe”
wall in concrete, in the living room, thus allowing the storage of thermal
energy from the sun. The covers are lined
with native vegetation, serving as a moderating temperature and thereby
increasing the environmental comfort of the interior space.
Excess rainwater is not
absorbed by the plants of coverage is filtered and drained to a tank adjoining
the office.This system provides
the ability to capture the rain water and use for the bathroom, treatment area
of clothes and dishwasher.
As for the
construction, we used continuous insulation - the exterior of the facades -
thereby seeking to minimize the thermal bridges and promote a strong inertia.The finishing on the floor in social areas is polished concrete that not
only was the desired aesthetic solution, is revealed as a less costly, durable
and, also with a good thermal inertia.
The emphasis on passive
solar systems has not shown significant increases in the cost of the work, with
a possible increase energy efficiency of housing without mechanical means only.
