Villa Number 599 is located in the coastal town of `Khaneh Darya´ (between Mahmoud Abaad and Sorkhrood provinces) in a land with a ground area of 623 square meters. What the contractor had in mind was to demolish the old villa and replace it with a new structure. The initial visit to the sight was done in May 2011 and the design process lasted up to October of the same year. Due to weather condition, the construction and building of the project began in June 2012.
When we talk of designing a villa, the general consensus is that an architect is less restrained to exercise his extravagant ambitions and to propound his special ideas, but many restricting laws and regulations in towns are so that maybe designing a villa is considerably more challenging. Because firstly the architect is presented with regulations and planning instructions and secondly he needs to satisfy the client’s expectations of a villa.`Khaneh Darya´ coastal town is of those towns with a thorough planning instruction that consists of the building location, allowed height, occupied surface and the substratum. Among these, the building location (a 10 by 18 meters box), allowed height (7.5 meters up to the highest point of the roof) and the minimum opening space to the neighboring area made more constraint on the design. Therefore the adopted approach had to use methods that were within the simple and conservative framework and at the same time committed to the regulations.
Solving climate issues and a new definition of sloped roof, evading the classic pyramid shaped villa, providing adequate lighting to the center of the structure considering the northern-southern protraction and providing acceptable view plus the aforementioned restrictions were challenges that influenced the initial design concepts. The contractor’s wishes were also discussed; the most significant issue for him being performance, permanence and ease of maintenance. Because he had infrequent and seasonal use in mind and it also seemed his children were the main target of the project.
With such emphasis on permanence, considering the environmental attributes of the Mazandaran province coasts was vital from the very beginning and sloped roof, the building sitting on plate, using huge openings through the northern-southern axis in the direction of air flow, view and light absorbance and also choosing building materials appropriate to the climate, were placed as the defining elements of the design frame.
Since there was no escaping the sloped roof, we made the decision to exhibit a different definition of it and avoid 2 or more sided sloped roofs. Therefore we separated the first mass of the building from the ground and created a continuous surface in the form of a folded sheet from west to east and entwined around it so the minimum required gradient for the roof (15 percent) was also safeguarded.
The ground floor which has mostly glass partitions, sat from the perimeter to the inside to add to the suspense of the upper volume and also to solve the regional climate issues.
The design continued from sections and the mass of the building, so that it is less compressed, was broke in length. As a result the first floor was divided in two by a void. Afterwards in order to repeat the skewed roof lines along the longitudinal section of the building and to intensify draft the upper section is located higher than the lower half and for a pathway between the two we passed a roofed slope outside the main structure and over the western patio. This method’s achievement, which is the only section connecting these two halves through what is similar to a sloped glass bridge, is significant to the project. In addition, the placement of a skylight over this void and the occurrence of light and shadow dancing throughout the day in the center of the structure, has created a magnificent visual quality for this coastal villa.
Providing vertical circulation is accomplished through the ramp which is located in the glass box between the northern and southern halves beside the vestibule. And so vertical and horizontal circulation are both achieved in the center of the building on two sides of the void.
In drawing preliminary diagrams two points were considered:
In the first floor, the service sector was placed in the center. The entrance, kitchen, staircase and the bathrooms are all located here to achieve a proper access diagram. The two north and south sections are envisioned for dining, living room and television room.
At first the structure was supposed to be concrete with repeating wall incisions so the pillars are eliminated from the first floor and a concrete sandwich is extruded horizontally. But midway through the design process, in accordance with the contractor’s wishes to control costs and simplicity in execution, it transformed into a mast pillar concrete structure. In order to exclude the walls pillar dimensions increased and we ensured they’re all placed in the walls. The maximum protrusion on the first floor is 2 meters and the final roof is in form of a skewed composite mast and metal profiles with final sheet covers. The staircase and slope are in form of additional steel structures connected with the concrete.
To provide cooling and heating fan coil packages are prepared which have built-in roof panels. To escape the visual pollution of coolers this was of special consideration to us.
The main proposition here was the continuation of materials from the outside to the inside and also the use of materials that were harmonious with background textures and also to avoid plurality. For this, saturated wood was our best option, because it has great durability outside and was in line with the overall façade of the project. Stone was also one of the materials used on the outside and inside. Considering the project’s concept, glass and dark materials were used extensively on the ground floor so it would intensify the pendency of the higher space in for of a contiguous white frame.
