Concept in construction

Construction is placed in the origin of the SMLsystem, trying to improve the construction process used in the SDE2010 edition with SML house.

Based in the modular system, we try to bring to the concrete the abstract concepts of efficiency and sustainability at the same time that we project a system which is easy to assemble and expand in the 3 dimensions with guarantee of creating habitable spaces with many options of customize.

The primitive concept is about continent and content. We concibe the module as a continent of habitable space perfectly assembled, where you can introduce prefabricated boxes,  in order to be completely customizable. Those boxes contains the wet areas (kitchen, bathroom) chosen from a catalog.

The module is formed by a laminated pine wood structure, ventilated facade in larch wood with composed closure (wood + isulation + wood + air camera + double gypsum board), and a vertical lattice system where larch wood and ceramics are used in order to get different thermal inertia and be able to use them depending on the external conditions. This system is dynamic, and allows the owner to create transition spaces between exterior and interior, just expanding them into the longitudinal module axis, at the same time that provides solar protection to the opennings.

The foundations are a system of laminated pine wood beams, placed in the cross borders of each module, with stainless steel supports which transmit, across steel sheets of 1square meter, the loads to the terrain.

About facilities, they are splitted in 3 parts the engineering box where almost all the photovoltaic, HVAC, domotic and plumbing elements have been moved, the facilities space inside the house, and all the solar panels setted in a pack that will be placed on the top fo each module.

As we said, the solar packs are placed on the top of each module with an independent structure,  which properly joins with the roof structure of the module. That point is important because all the facilities which are complex, are setted up so the work is just execute joints between the module and facilities pack,that minimizes personal risks  implicits while working on the roof, and construction problems like damages on the waterproof layer.

 

STRUCTURE

In SMLsystem, we choose an assembled elements structure system in wood, mainly with 2 different elements, columns and CLT panels.

The main module is composed by 2 CLT panels of 7.200 x 3.600 mm, which are used as floor and roof structure, and 4 columns in L form with dimensions of 310 x 310mm and 100 mm of witness. The L form of the columns is the result of the aggregation process, trying to create, with the aggregation of 4 modules, decomposed columns with cross shape as a way to reduce the presence of the column in the space.

On the CLT panel, 2 wood beams are situated linking the head of the columns with a high resistance steel profile which is used to raise the module in the construction process. That beams set up 3 vessels which have a low slope to pick up the water in one of the short sides of the module.

Also those beams help us to fix the solar systems avoiding problems of ruptures on the waterproof layer.

 

CLOSURE

The clousure is executed as a ventilated facade. The exterior layer are larch wood pieces fixed to the main closure with an aluminiun substructure screwed to the wall.

That wall is composed by addition of Lignum pieces. Lignum are long pieces made of pine wood in the perimeter (like a chest) and filled with thermal and acoustic isolation material (rockwool).

Next layer is an air camera with the aluminium profiles necessaries to support the double gypsum board that will be painted in white leading the interior facade.

So at the end the clousure will be a succession of  those layers:

Larch wood panels + ventilated camera + pine wood panel + rockwool + pine wood panel + air camera + double gupsum board.

 

LOUVRE

The louvre is a complex system composed mainly by larch wood ribbons with section of  50 mm x 150 mm.

The single element of the louvre is composed by two ribbons, one horizontal and one vertical joined by stainless steel ironwork, which allows to turn the vertical ribbon. That vertical ribbon has one side covered with white ceramics pieces in order to get contrasted facades with different thermal properties depending on the external conditions.

Those elements are grouped in each module, setting a system, which is able to move in the longitudinal direction and let the vertical ribbons swing to generate 2 different facades (ceramic or wood aspect).

 

INTERIORS

The interiors are designed as a contemporary spaces, with light colours and continuous spaces, trying to avoid the topic vision of a wooden house.

The floor is projected as ceramic pavement because of their great thermal properties, and the high industrialization, quality and design of this material, at the same time that we promote the industry of our region. In some places mini fan coils will be integrated into the floor to guarantee confort conditions.

The walls are guypsum board painted, getting continuous white plans that gives more spaciality to the interior.

The ceiling is a continuous plan also, which is used for the cooling and heating system, running water with different temperatures depending on the conditions into the ceiling.

 

BOXES

Those boxes are prefabricated sub modules that contains full kitchen or bathroom which  can be introduced in the SMLsystem modules, setting the space of the house.

Those boxes are prefabricated by Porcelanosa and would be different sizes of each one addpated to the size and necesities of the house.

They are built with water-resistant gypsum board and aluminium profiles and covered with ceramic pieces.

All the facilities are prepared to connect with the house inspection hatch.

 

FACILITIES

Facilities are splitted in 3 parts the engineering box where almost all the photovoltaic, HVAC, domotic and plumbing elements have been moved, the facilities space inside the house, and all the solar panels setted in a pack that will be placed on the top fo each module.

As the SMLsystem has been designed for the most comfortable conditions, many facilities are needed, which represent a problem in terms of surface occupation and noise. For that reason an engineering box has been designed with an steel structure independent from the house, where almost all the photovoltaic, HVAC, domotic and plumbing elements have been moved. The engineering box is a room of approximately 1×5 meters and 1.5 meters high. It will be placed next to the house and the shape and materials will be such that provide a proper integration within the environment of the house.

The engineering box frees up space from the house, providing more architectural flexibility. There is also more space available for the equipment which eases maintenance. As located outside the house, noise problems due to pumps or moving elements are eliminated.

The most important advantage of the engineering box is assembly as it has been divided in three independent departments attending to the function: HVAC, photovoltaic and plumbing. Each part can be assembled independent from the rest. This means that the parts can be assembled in different places and even at different time, no longer dependent on the house. Then the parts are put together and linked to the house by means of an undefloor connection.

As we said, the solar packs are placed on the top of each module with an independent structure,  which properly joins with the roof structure of the module. That point is important because all the facilities which are complex, are setted up so the work is just execute joints between the module and facilities pack,that minimizes personal risks  implicits while working on the roof, and construction problems like damages on the waterproof layer.

 

BUILDING PROCESS

The building process starts with the foundations, defining the position of the support on the terrain, and setting all the foundations beams system.

Once this step is ready, the first module will be raised with a crane, from the poins determined in the structure, and will be sitted on the beams in the correct position. This operation will be repited with the second and third module, getting the main space setted up.

After the modules are fixed in the final position, the lattice will be extended following the drawings, and generating the transition spaces betwen interior and exterior, the private and the public atmosphere.

While in the interior  are finishing all the details , on the top of the modules, the facilities pack will be placed and connected to the house, and also the engineering box situated on the exterior space will be connected to the house.

After details will be finished, furniture will enter in the house, giving to the space the habitability and finishing the construction process of SMLsystem.

SMLsystem is ready.
