Casa de Bloco Inovadora de Stewart Farmer Winslow - Arquitetura e Design Sustentável

3 BOND BOSTON SOCIETY OF ARCHITECTS STEWART FARMER WINSLOW Down EAST SEPTEMBER OCTOBER 1969 The Home of the Concrete Blockollipop designer Stewart Farmer Winslow These are tentatively underway but as you can see we need a lot of cooperation from companies involved There may be so many variables that we have to limit the process to the number actually purchasing a given design Stewart Farmer WINSLOW is an architect designer and free lance writer who lives in Cambridge Mass a highly wired community which could benefit from improved energysaving measures The solar water heating system p 35 is one of many measures taken by Winslow whose design for a block house is discussed below It took Won Slow three years before he found architectural financing to build his innovative home on the site of his fathers farmhouse at Orleans Cape Cod Although the Winslow block house resembles many regional homes the prototype incorporates several unusual features to make it truly innovative Besides the solar water system a solar air heater designed and built by Winslow preheats ventilation air and helps warm the house including the greenhouse a credit is due the ventilation system whose motor uses only II watt Mr Winslow paid 1 an hour to his son and a friend to hammer out the ten foot by elevenfoot blocks on the farm site The blocks are made with a standard concrete block machine and using this technique were finished in three days Against prevailing custom the block faces are oriented inward so a stucco finish can be applied outside if the owner wishes The home cost 40000 but the land was free and many of the systems were built by handson work Designed for a 46 ft by 86 ft lot the Winslow block house is roughly the shape of an L Although the floor plan is staggered and the glass is strategically oriented to face the south the form is fairly traditional with an extended gable front and an open space overlooking the water The basement footings and walls were poured within one week Although rebar was used in the block corners the walls are predominantly self supporting Both the interior and the exterior walls are load bearing The Winslow block house is a pioneer in an area of architectural research ironically where the architectural profession has been slow to act The block home answers the emerging needs for homes which consume less energy and also provide a more practical design for the man doing construction and reconstruction with a minimum of formal training Unlike the wood frame house the block house requires no carpenter to construct The waves of the Cape wind can be heard at all frequencies but the solidsubstance of the walls minimizes the noise from outside While the block house does not provide a definitive response to the energy crisis it does provide a starting point and useful prototype in a variety of directions The key is the use of the concrete block and the special machine used to fashion the blocks on site The machine costs about 500 and process is ten times faster than conventional block laying While plaster and stucco finishes can be used outside the block itself lends a special character to the walls and can be made very colorful The block is made of local sand cement and lime It is not a load bearing system as used in conventional concrete block homes Although the present design used the concrete block made with a crane for other applications of the system the crane could be used to fabricate other concrete components such as precast walls and roof panels Laboratory tests have shown that the block and system will meet ASTM structural standards The block is finished with a smooth face and a pattern is formed by using edge moldings The slots of the block are formed so that they can accept steel rods for reinforcement The block faces inward and thus the roof can transfer the loads to the walls without a need for additional wooden headers or roof beams The concrete block house provided the Winslow family with a relatively inexpensive home designed and constructed on the Cape Cod style The form and systems of the house represented several modern ideas but the basic floor plan stays firmly traditional The house is a useful model for experimentation with solar heating since the walls store heat and the south glass provides solar gain in the winter The block house is a prototype for mass production of new homes built with concrete blocks transported to the site or made on the site Thanks to many friends for valuable advice and help in making this project a reality STEWART FARMER WINSLOW ARD 661 Massachusetts Avenue Boston Massachusetts 02118 will be glad to discuss your specific problems and help develop concrete housing programs Concrete newsletter and the Rhode Island

class of architects in a high school course An engineer is someone who does for a dime what any fool can do for a dollar He went on to point out what many architects already know it is fully possible for the production architect woman or man to do the fool job and not the engineer job and vice versa This outlining of pros and cons leads to a practical suggestion useful to small firms and large The suggestion is that a firms production specialists should be assigned welldefined jobs and that there are three especially useful lines of thrust development of plans and drawings the quality assurance and systems development The world is generally accustomed to viewing architects as being concerned primarily with design Other matters are universally recognized but almost exclusively by operations executives in the architectureengineer construction field production can be assigned by senior or midmanagement personnel But many architects seem untrained in production specialization The production architect woman or man should be assigned a recognized job that makes use of his or her talents training and work experience Design is preferable but draftsmanship cost estimating and production specification writing are all completely valid specializations A firms production specialists should be limited in the scope of their assignments to avoid burnout and excessive workloads for example one of the authors first architectural jobs was doing everything including shop drawings client contacts estimations and finally design as well It was clear to many bosses and job holders alike that this was a failure On the other hand this is an extreme example and may be the reality in many small firms In modern architecture qualities or talents used in production are a special interest skill in layout an ability to communicate and conceptualize clarity of detail understanding of economics an understanding of client problems and general knowledge of construction The new architect must eventually select a specialization that suits him or her and this ability then allows success and growth in the profession These thoughts do not imply a persons qualifications There are multitudes of highly talented men and women capable of doing both design and production What is important is that the personnel allocations in a small or medium size firm reflect the same specialization and productivity that prevail in large firms The architecture professional has the final responsibility for every project however good architectural production specialists can make or break either a design by the design group or a study program or an entire project by specified rigorous efforts on production As many others have noted there is too much tendency in the profession to view production work as something that anyone can do in reality production means management of the design and it should be well paid recognized and advanced
