"Hillcrown" Residence For Lawrence Petersen And Linda Fox

Carrboro, North Carolina USA

The owners are both photographers who envisioned a home that would also act as a photographic studio, exhibition gallery and gathering center for artists throughout their local area. One of their requirements was that the design be highly resistant to hurricanes and be simple to construct because the owners would act as contractors for their home. The design consists of a central ¾ sphere 50 foot diameter dome interconnected with a smaller ¾ sphere 30 foot diameter dome with a third 16 foot diameter cylinder structure integral with the main sphere. The domes are constructed using an inflatable balloon that is custom-made to replicate the entire shape of the home. When this balloon is positioned and inflated, steel rebar is set in place, wire mesh is tied to it and spray-on concrete is applied to the exterior surface. The entire structure can be completed in a day. This process is patented by Monolithic Dome Company in Texas and is tested to resist a minimum of 300 mph winds. Specially selected mica chips are applied to the gold metallic and tan/orange colored outer surface of the house to create a shimmering, crystalline quality not unlike natural mineral crystals native to the area.

The light colored interior also features this reflective mica chip texture. The house contains a sub-level basement photographic development studio and exhibition gallery with an outdoor path that leads to a loading/unloading area. Upper levels contain two large bedrooms with two adjoining bathrooms, a large kitchen, "green" room, living and dining spaces that open onto a south and west facing patio terrace on the ground floor. Two stairways access the second studio level which contains a bathroom, library and multi-purpose room. An outdoor "look-out" tower is accessed from the second floor library and allows one to view the forest at tree top level. The house has several ecological technology features such as a rain catch roof gutter system that drains to a sunken water basin which is the source of all grey water usage in the house. A constructed wetlands pond, at the east side of the house, filters and cleans black water coming through the house and is recycled for grey water use. Three large photovoltaic panels at the north side of the house supply electricity and are protected from high winds by a semi-circular soil/grass berm which also protects a large vegetable garden with an underground irrigation system feeding off the roof rain catch gutter system.. This house is a self-sufficient living system that directly utilizes and enhances its natural surroundings as well as provides a functional and exciting artistic environment for its owners. An ecological and spiritual setting for all who experience it!

"The Insect House"

This house is known as a "Reyes House", a remodel & addition whose owners are Remy and Vince Reyes. It's location is in Oakland, California.

Project Managers: Mr. Scott Looney and Ms. Tze Yan Szeto
Contractor: Mr. James Corrie, Man Made Construction and Tsui Design & Research Inc.
Date: 1991 to 1993 (Design and Construction)
Cost: $44,000.00
Square Footage: Approximetly 700 square feet

Construction Materials: Douglas Fir, plywood, acrylic panels, marine fiberglass, galvanized metal pipe, steel cable, "Structolite" plaster, concrete and schedule 40 steel pipe.

Special Features: Spiral viewing window, frameless acrylic openable windows, earthquake resistent tension cable shelves and tables, hand-sculpted structural plaster, radiant recycled water floor heating, hinged "dragonfly" roof ventilation "wings" operated by hand ratchet cranks, earthquake resistent truncated cone structural design, "Polygal" thermal/transluscent skylights, outdoor tension cable bracing system.

Owner Requirements: Convert the ground floor to accommodate a single bedroom, a bathroom, office/study, photo gallery, storage areas and an exterior solarium recreation room. Include a stairway up to the second level (main entrance level).

Ecological Requirements: None

General background of the Project: Vince and Remy Reyes live in a house in Oakland, California with their three children and grandfather. They needed more room in their home and wished to remodel an existing ground floor/basement as well as build an exterior recreation room to their house. The Reyes' wanted something innovative with the feeling of softness and continuity. The overall design was developed jointly between architect and owners with both parties sketching out their ideas and the architect bringing the ideas together in a cohesive whole. Working drawings and the issuance of a permit to build went smoothly. The building department personnel were excited about the project. In fact, when the building inspector arrived to issue the certificate of completion, he brought his camera to take photographs. Similarly, the neighbors seem very supportive of the project during its construction and enthusiastic individuals freely volunteered their time to see the project to completion.

"The Alien Water House"

This structure is called the "Aquaterra", a tourist vistation house in Woodacre, California USA. The developer of this unique, out of this world building is Mr. Greg Snowden. The cost of its first prototype is approximately $8,000,000.00 with the area of 12,000 sq.ft.

Here are some of the details of this remarkable design:

Construction Materials: Vegetable-based plastic, ceramic/glass composite, lightweight, high-strength concrete, stainless steel, flagstone, glass laminate, madrone and monterey pine finshing wood.

Special Features: "X" plan bridge structure, earthquake resistant with spring-loaded, neoprene gasket design, roof deck water-filled skylight, aerodynamic design to enhance hillside updraft to power two "eggbeater" windmills, completely self-sufficient, photovoltaic solar cells for electrical power, 60 foot waterfall to recycle and cleanse water and to control temperature and humidity build-up, house walls are water-cooled, see-through acrylic/glass pool structure, house completely leaves the natural ecology undisturbed, two walk-way bridges lead to two separate levels of entrance.

Owner Requirements: The house must be appealing and educative to all ages and generations of people; must be absolutely ecologically sensitive to the site and to its own functions; must be self-sufficient in energy use; wherever possible use materials and methods of construction that are not harmful to the environment.

General Background of the Project: Mr. Greg Snowden saw our work at the Celebration of Innovation Exposition in San Francisco. He has a profound interest in ecology and permaculture and wanted to build a building that would be the ultimate in advanced ecological design. The house also had to be something striking, timeless and mysterious so that people would want to come back to see more. Mr. Snowden had an option to purchase a five acre hillside property which faced west. The property had consistent presence of wind which made the use of windmills a probability; it also had a 30 to 45 degree incline. Since Mr. Snowden was strongly in favor of not disturbing the land a concept emerged where the building might soar over the site rather than try to excavate into the hillside. Excavating would be both costly and harmful to the site's ecology.

The functions of the house, given the programmatic requirements, become an educative experience to the public. The house contains the following functions not normally understood by the general public:
1) Sewage water cleaning system using sunlight and water plants recycled throughout

2) "Eggbeater" windmills for electrical power

3) Cold water recycled throughout the walls of the house for summer cooling

4) Integrated photovoltaic solar cells for electrical power

5) Specially designed earthquake mitigating shock absorber foundation plugs

6) "X" configuration arch structure for unilateral stability

7) Aerodynamic design that acts as an airfoil to accelerate wind uplift to windmills

8) Suspension design that allows downward vistas through the floor

9) Waterfall cleaning system for general use water

10) Roof garden terrace with see-through stone and glass composite floor

11) Non-mechanical air conditioning and heating system

12) Prefabricated, post-tensioned structural system for ease and efficiency of construction

In plan the "X" configuration can be likened to a person stabilizing themselves facing downward with their hands and feet spread evenly apart on the floor and body off the floor. During an earthquake this low, four point position is extremely stable for it minimizes contact surface area, affords a very low center of gravity and makes the possibility of overturn very difficult. The "X" form also provides lateral stability so important to aerodynamic efficiency.

The living areas of the house are suspended from the "X" bridge giving the structure flexibility in the event of an earthquake. The symmetry of the egg-like shape also provides an energy efficient design minimizing the surface area and maximizing structural strength. Aerodynamics plays a key role in the design because the climatic conditions of the site dictate a design that must respond to heat year round. Therefore a form that disipates heat and is aerodynamic must be chosen. One of the most effcient forms for air flow is the saucer shape but its streamlined proportions make it difficult to accommodate an effective use of volume. The next progression, then, is an inflated saucer shape which then approaches the egg shape.
