Solar Umbrella

Model Rebuild - When remodelling their own residence Angela Brooks and Lawrence Scarpa could never have imagined the press and accolades that would be bestowed upon a build designed around their own very personal needs. Economical, solar powered, solar water heating, nearly off the power grid and with a fitting yet aesthetically contrasting extension. A rear extension that embraces the house's 1920's bungalow origins and pays homage to its design sake, the Paul Rudolph Umbrella House of 1953.

Overview and Plot
The lot, in Venice California, typical of the area, has two road frontages. This allowed the house's orientation to be flipped, the crux of this build. With the living area and kitchen behind now facing the larger rear garden, an additional bedroom was added upstairs, and the second bedroom converted to an office. Most of all, the flip orients the house to the southern sun allowing the sun's energy to be stored in the concrete eastern and western walls and floor.

The extension has the majority of its glazing along the warmth facing southern wall, with northern glazing opening up for cross ventilation. The architects describe it as "global regionalism," Californian indoor outdoor flow, wrapped in modern technology using recycled and sustainable materials, offsetting the use of concrete with gains made through its thermal storing properties that lead to lower power bills. Overhangs regulate the sun in its strongest months and double glazing with a low-E film , framed in aluminium with thermal breaks, control the wind and indoor environment. To save on materials the solar panels themselves form the outer canopy and Solar Umbrella, shading the house. With the rear set up, insulation was blown into the walls and floors of the original wing and operable skylights in the kitchen and bathroom provide natural light and ventilation whilst maintaining privacy.


In winter, warmth is provided through radiant in-floor heating powered partly by one of three solar hot water panels. Two are used to pre-heat the domestic hot water before it gets to the gas-fired hot water heater and the other to heat the pool. These panels halved the gas use of the house which is now 2.5 times as big! As usual there was initial outlay for the solar water heaters and panels, which 10 years.

Living area extension

Although the double height extension sets the house apart from its neighbours, the fact that it is at the rear facing the alley, contrary to most of the houses on the block, mean its northern facing traditional façade, lets it fit in with the Joneses. The services are concealed up the side of the house, and a bike rack just inside the new front gate provides mobility to the nearby shops (apparently a novelty in the US).


Well thought out landscaping incorporates gravel, to allow the plot to drain and prevent it from heating up like large paved areas do, and planting is drought tolerant, with species that appeal to the abundant hummingbirds in the area. The new pond and pool also help regulate the temperate and composting was also included as part of the landscape design.

A relatively simple layout provides for both open plan living and more intimate work and rest areas.
Downstairs the office, with access to the main street, sits beside the second bedroom and main bathroom on the eastern wall. The living room and kitchen take the southern and western walls respectively. As well as allowing heat to rise up and out the upstairs windows, the industrial like steel stairs link the downstairs area to the more private master bedroom with en-suite.

The Results
The house now provides an additional open plan living area ideal for the couple's son, connecting outdoor play and space indoors. The Solar Umbrella plays its dual role, keeping the house cool and shaded in summer and warm through its solar panel composition in winter. Utilitarian, the house is built to be lived in and enjoyed rather than as a show-piece 'typical' modern build. This to me is what makes this a home.

Steven Holl | Planar House

Steven HollPlanar HouseDesert Tilt Up Wonder - This Steven Holl designed residence in Paradise Valley, AZ, USA, uses raw Concrete and Corten Steel to create a great prefabricated home and art gallery for it's owner.
Designed to house a contemporary art collection, internally, the house sets out to be a blank canvas, not to distract from the works held within.

The street façade blends into the desert greys, with the ageing steel fitting in perfectly.

Flourishes on the exterior are limited to the courtyard from where a ramp leads to a rooftop sculpture garden - a place of silence and reflection.

The rear, with overhands for shading, is the largest expanse of light giving glass. These sliding openings taking in views to the nearby Camelback Mountain.

The house is broken up into three functional areas. The garage and master bedroom, together with the library form the quiet zone at front of the house. To the rear are the dining and kitchen areas, located to soak up the views …

Portelet House - BAS MooArc

Guernsey Beach Villa - The Portlet House is one of many fantastic works on Guernsey by BAS MooArc - Minimalist style creating a welcoming beach retreat...more

Well after a huge hiatus, I though I would post this gem to rekindle the spirits as Christmas approaches. After a quick catch up on Facebook Jamie Falla kindly provided me with some floor plans to their Portelet House, overlooking Portelet Harbour - Guernsey.

Conceived as three timber blocks nestled into the hillside allowing views of the surrounding landscape from all principle rooms. The palette of materials blends with the beach setting and mediates between water, earth and sky.

With sea views out to the North - the house faces a battle between light and distractions. Rightly so, large full height glazing faces out to sea from both the living and dining room. These comprising two of three connected timber blocks. Angled skylights and clerestory windows ensure that the hallways and bedrooms are also doused in daylight.

Lund Hagem - Cabin Ameln

Lund Hagem, based out of Norway have a fantastic site, and collection of baches. Cabin Ameln, a providing sheltered BBQ retreat, and views out across the fjord. Contour hugging hunkered in design, connects with the site while minimalist layout and crisp finishes set it apart from your ordinary weekend retreat.
Location: Østerøya, Sandefjord, Norway
Size: 90 m2
Completed: 2009
The building sits in sloping terrain in close proximity to the sea. It has been designed to create favourable, screened outdoor areas. Previous buildings (4 in total) have been demolished and replaced with one new building that collects all functions under one roof.
The L-shaped layout uses steps to follow the terrain so that the building can utilise existing vegetation and trees to avoid visibility from the sea. This layout creates one upper and one lower outdoor area/patio. The upper patio has been duly
screened from the seafront, but offers views through the building due to glass walls.
