Overview
The project's focus around the specifics of the site and putting the personal and particular experiences above the powerful and the public, seeks to create a mood which is meditative instead of tensing or relaxing.

The site is hidden from the public road and is accessed from high ground on the landward side where the first experience is of an elevated view of the site and the sea beyond. Therefore the importance of the roof, or fifth façade, dictated a metal zinc cladding which is suitable for both walls and roof. Said façade, mimicking the seaweed found on the shores beyond. The anthracite colour of the zinc makes the building camouflage itself into the heather landscape.



The roof of both living areas is flipped and directed in opposite directions and towards particular points in the landscape and sunlight. Both living areas are fully glazed, thus embracing nature and developing a conversation with it. By way of contrast the sloped slit windows of the bedrooms act as a counter point to the absolute horizontal of the ocean horizon.

In order to emphasise the fact that the owners were embarking on a holiday each time they entered the house, the step and entry ramp at the front door is disconnected from the building thus making the visitor step over a gap not unlike stepping from the static platform onto a passing train. Thus a physical step from the day to day life into this adventurous house.

Layout
The plan form was inspired by the traditional narrow cottage and is orientated towards warm southern sun. It contains three sleeping cells and auxiliary spaces in the middle with two living areas, one at each end, connected by a library. Glazing is relative to the function of the rooms, with the centre bedrooms and auxiliary spaces horizontally glazed with small landscape framing windows, while the end living areas are wide open to the surrounding views.

The roof rain water is drained by way of gargoyles making one aware of the elements even in the lightest of showers, thus reinforcing the connection between inhabitant and nature.

For us, ‘Tuath na Mara’ is wonderfully paradoxical: profoundly contextual and strikingly free-floating.

It is contextual in two senses: Firstly it speaks to the built experience of both our families, being the width of a house on the west coast that has been in the family for generations, and having the name and some of the shape of a house built by a Scottish grandparent (‘Tuath na Mara’ equally well in Scots and Irish Gaelic). Secondly it is rooted in the Donegal landscape, or more precisely in the inter-tidal seascape with which it shares its colour and, very nearly, its location. From the sea, it is virtually invisible.

But it is also free-floating, both in the way it sculpts light internally, and in the way its design is part of a cosmopolitan architectural conversation that is above national boundaries. This global-local interchange marks it out as capable of belonging only to the 21st century.

Overview

"At the end of 2002 the clients approached us to design the house.
They wanted to build this new house next to their one, in the garden facing the lake, and they were after something typically razionalismo comasco, architecture of the thirties driven by architect Giuseppe Terragni. So they chose the project that best met their expectations, ours. The project's main idea gave the name to the building: casa del masso." Marco Castelletti.
The house, set on a steep slope above the street, can be clearly seen across the lake.
The building stands by the side of the client's old house designed by engineer Luciano Trolli in 1955, and it takes advantage of a little tract of flat land, as does the original residence.
The house is linked to the street by a long flight of steps which wind along the slope and down to the house, which is organised over two floors.

Layout
The composition is based on the intersection of two volumes:
The first - facing the lake, is an horizontal structure supported by pilotis houseing all the living and bedrooms.
The second - is vertical holding the staicase and the services rooms.

On the first floor the living room crosses the house and is directly connected with the slope behind. Here the presence of a erratic boulder, in italian language "masso" (here is where the name of the house comes), protrudes into the dwelling as the characterising element of the space, so that it seems that the house is anchored to the slope at this point.
The boulder can be seen through the glass floor of the living room.

From the parking area you reach the main entrance via a flight of steps or an elevator running on the side of the garden.
After reaching the main entrance a footpath covered by a overhanging volume introduces a little hall where you can see the landscape and the monuments of the city.
From here, a large staircase takes you to an atrium with the large glass window which frames the erratic boulder. The internal layout of the main dwelling faces the kitchen, the living room and some other rooms towards the lake, while bathrooms, services and the laundry are put towards the slope.

The materials used to build the house enhance the volumetric composition and the difference between the horizontal volume, suspended and completely covered by white marble dust plaster, and the vertical covered with a natural stone called Iragna, laid down in horizontal layers with different length and thickness.

The same stone was used for the external pavements, the main entrance staircase and the terrace floor on the highest level.

The large windows are divided in sliding parts with electrical rolling shutters made of aluminium.

Solar exposure is optimised wit hteh building orientated with its largest windows and rooms to the south, and services and bathrooms facing north.

ResultsThe clients were really satisfied of the project and followed all the phases of the building that, because of the particular nature of the steep land, involved many challenges.
The crane to build the house was placed on the slope with an helicopter used to transport heavy weights. None the less, the house was completed in seventeen months, from May 2003 to December 2004, as stipulated.

• Passive Ventilation – eliminating the need for a forced air system the shaded front living area naturally ducts cool air up thought the house and stairwell, then out the temperature sensitive skylights.
  
• Solar Energy – an array of 20 solar panels on the roof supply around 70% of the home's energy needs
  
• Photovoltaic Panels and Flat Plate Collectors – providing hot water to the water heater and subsequently the radiant heating system in the concrete floors. David says to heat the place, with these panels installed takes about as much energy as a 60w light bulb, all taken from his solar array.
  
• Vacuum tubing on the roof, which uses a parabolic collector to focus the sun’s rays, provides additional hot water
  
• Recycled FSC certified sustainable woods such as Ipe, Mahogany and Fir
  
• That Syndecrete®, a light-weight concrete that uses 41% recycled content - it also holds various pigments and textures to form furniture throughout the house, like the kitchen bench, table and bathroom sinks.
  
• Zero VOC paints
  
• High performance heat-mirror glazing
  
• The pool system uses an ionization and silver filter, eliminating the need for chlorine
