The stunning copper roofing turret featured in today's architectural blog article is fashioned from custom diamond shaped copper roof tiles and is topped with a spear shaped copper finial turret roof cap. This lovely turret copper roofing graces and enhances this beautiful new home undergoing final stages of construction. Additional custom copper work includes copper flashing, half round copper gutters, round copper downspouts and copper leader heads adorned with copper lion head castings. Radius round copper gutter encircling the base of the copper turret roof is planned.

Each year the North American Copper in Architecture Awards acknowledges and spotlights selected North American building projects for innovative and exceptional use of architectural copper. The architectural copper awards program highlights a wide scope of projects which highlight craftsmanship, attention to detail, and architectural vision. Copper has historically long been used for its great natural beauty and finish, it's durability and performance, copper's long service life and recyclability. Copper is still today a superior building material and also one of most eco-friendly and green building materials, which is being utilized and adapted for an ever wider variety of contemporary and cutting edge building and architectural applications. Three of the twelve copper in architecture award winners are described and shown below.

The Waipolu Gallery above uses copper wall cladding and copper roofing which were chosen for this project as copper will perform well over a very long time and with very little maintenance in a very corrosive ocean side location. Copper's beauty and fluidity compliment the modern art contained within the structure. The copper provides a softer contrast to the other more linear materials used. Excellent workability or malleability of copper was advantageous allowing easy re-working or shaping on site. The building architects also like there will be changes in copper's patina or color over time, producing an ever evolving work of art. The studio with it's stainless steel, glass and concrete linear space is joined by a floating glass bridge to the copper clad gallery. The glass bridge rises above a limestone staircase which connects the building's three levels.

The Mark Olsen Project exhibits excellent old world craftsmanship, with a copper roof and other architectural copper features such as copper finials, copper gutters and ornamental downspouts with copper conductor heads, copper crown molding, fascia and soffit, copper chimney top shroud and extended copper window box. This stately home has exquisite detailing and exudes quiet elegance from it's naturally weathered copper features. 16,000 pounds worth of hand crafted architectural copper work are used for this home's architecture. The copper roof is comprised of diamond shaped interlocking copper shingles, copper ridge vents and flashing. Of note, no sealants were used, only traditional craftsmanship and installation techniques were employed along with some soldering work on the copper gutters providing very long term durability with little to no maintenance required.

One hundred fifty years in the making, the Cathedral of St. John the Baptist in Charleston, South Carolina has at long last been restored after being completely destroyed by fire in 1861. A soaring neo-gothic style copper spire, which had long been planned, was finally realized this past spring. The stunning beauty of the copper spire with it's gold leaf finished copper cross can be seen across the Charleston skyline and out to Sullivan Island. The cathedral's tower was finished with a stone veneer and at it's top there are four copper clad archways with copper torch finials. The copper spire with gold-leaf copper cross finial is perched on top at center of the copper arches. The 200 square feet of gold leaf which covers the cross will last at least 40 years without touch-up while the crowning copper art work comprised of arches, finials, spire and cross at the peak of the cathedral will last and stay beautiful for generations to come.

Gazebos are an outdoor pavilion or tent like structure which are usually round, square or octagonal in shape. A gazebo is a familiar sight, found just about anywhere, in parks, gardens, back yards, on a lake or seashore, outdoor restaurants, etc. Gazebos are usually roofed but open on the sides, sometimes with railings or balustrades and sometimes screened in. The gazebo floor might be grass, stone, concrete, brick or raised wood deck. The gazebo's base or deck and the optional railing usually follow along the bottom outline of the gazebo roof (round - square - octagonal - etc). A gazebo is oftentimes free standing in an open area or can be attached to another building or connected by decorative wall or path. Gazebos are popular spots, especially in warm weather, to rest, entertain, eat, relax and socialize. A gazebo provides shelter, shade and often seating and tables. Gazebos are unusually appealing structures and provide a most attractive and ornamental feature to a property's architecture and landscaping. The most common gazebo is built out of wood with ordinary roofing shingles used on the roof. A simple metal or copper roof cap with finial might be found on top. A gazebo upgrade might involve a small cupola perched on top of the gazebo roof, once again with a roof finial crowning the very top. The ultimate gazebo roof is a copper roof made from copper tile or copper panels. A copper gazebo roof may be conical in shape, bell shaped, octagonal, pentagonal, pyramidal, domed or any number of different shapes.
 

For the framework we will be using aluminum tubing, plywood sheathing and waterproof membrane. We begin by precisely cutting square aluminum tubing to size and bending the tubes using a roll forming machine to form the base and the many vertical support cross members. A partially completed aluminum frame is shown below.


After all the plywood sheathing panels have been securely fastened in place with self-tapping screws, we then apply to the partially completed dome a self-sealing waterproof membrane, taking care to completely seal the dome. After the membrane is in place, we draw guidelines and begin carefully attaching the hand-cut copper tile to the dome and to each other. The copper tile have been designed to interlock securely with each other and we use copper ring shank nails to fasten them to the plywood.

The need to prevent the spread of germs has always been a major concern. Research indicates that a copper surface is more effective at preventing the spread of germs than stainless steel. Copper has a 2000 year history of antimicrobial applications in a multitude of cultures. More recent research has sought to determine uncoated copper's effectiveness in stemming the proliferation of infectious disease. At the University of Southampton in the U.K. research studies have shown that many common disease causing microbes such as  E. coli, Aspergillus niger (black mold) and Influenza A, die within hours on copper surfaces. The Influenza A family of viruses includes the problematic Avian flu and swine flu strains and copper can help contain a flu. Even deadly antibiotic resistant bacteria associated with infections such as MRSA (Methicillin Resistant Staphylococcus Aureus) die within 1.5 hours on pure copper. On stainless steel and plastics, typically used for food-processing hardware, pathogens survived unabated for days, sometimes more than 30 days. There is enough solid evidence to put man’s oldest metal to work throughout the world to help protect us from infectious disease. Tested copper alloys, such as brass or bronze also offer increased protection over non-copper containing materials such as stainless steel, painted surfaces, wood and plastics, although not nearly as effective as pure copper surfaces.

Some fairly common and obvious uses in the home for elegant yet functional copper home decor include copper kitchen sinks, bathroom copper sinks, copper bar sinks, food prep sinks, copper basin, copper vanity sink, copper door knobs, copper handles, copper range hoods, copper planters, copper pot racks, copper bowls, copper sheets or copper tiles for making copper countertops and copper sink backsplashes, copper tabletops, copper chair arms, copper wall plates and switches, copper light canopies, copper ceiling fans, copper vents, copper louvers, copper cookware, etc. There are germ killing copper facades available for refrigerators, dishwashers, freezers, ice-makers, ovens and ranges. There are copper-plated kitchen appliances, copper vases, copper sculpture, copper accent pieces, copper planters, even copper flowers. Copper bathroom fixtures and copper kitchen appointments may be the most obvious places to most benefit from and utilize copper's antimicrobial power, yet manufacturers are now focusing in on all home furnishings and furniture as well as laptop, remote control and cell phone cases. The ceiling for new copper surfaced products is sky high, especially considering copper's aesthetic qualities, durability, long lifespan and green copper work as eco-friendly too.
