Anabela Carvalho “O meu adorável T1 da Casa Diff: Como aconteceu e como surgiu? Tudo começou há alguns anos atrás e antes da pandemia, eu tinha um sonho, um desejo, criar um Cohousing, uma "Tribo", um conceito já muito usual nos EUA e nalguns países da Europa, mas impensável em Portugal, onde os lobbies da construção, corporativismos, câmaras e licenciamentos infelizmente bloqueiam qualquer conceito inovador, por mais fantástico e funcional que seja... Posta de parte essa ideia e porque sou de desafios e não desisto facilmente, durante os passeios por trilhos que com o meu cão, todos os dias fazia nesses 45 dias de confinamento onde me encontrava, mais precisamente na quinta de um familiar muito próximo, apercebi-me dos terrenos que estavam ao redor mas na altura não para venda. Não sosseguei enquanto não descobri quem eram os proprietários e depois de alguns avanços e recuos, no Verão de 2021 eu adquiri o meu terreno com um hectare e dei-lhe o nome de Xitaca, nasci e vivi em África (Angola) e é esse o nome que é dado a uma quinta, a um sítio como este... Depois começou a saga da procura da casa, a condição era ser pré-fabricada, apenas um T1 era mais que suficiente, a ideia era adaptar o conceito do cohousing (Tribo) muito mais alargado, a uma solução mais simples e meramente familiar, como a Xitaca, com casinhas como a minha e para quem deseje seguir o meu exemplo, filhos e/ou netos, intergeracional portanto, a condição é serem todas da mesma tipologia T1, é mais que suficiente para cada um poder usufruir do seu espaço, com liberdade absoluta, apenas se exige uma zona de convívio e lazer comum e as despesas serem partilhadas, é um conceito e solução que contempla o aqui e agora mas também o amanhã, o futuro, gerações interagem e partilham espaço e convívio, liberdade e segurança familiar, a terra produz muito ou quase tudo, a natureza envolvente traz paz, harmonia e sossego, tão difíceis de serem encontradas nos dias de hoje... Como fui parar ao showroom da "Casa Diff" no Seixal?... Não tenho ideia, só sei que corri Portugal de norte a sul e as dificuldades foram imensas, a instalou desilusão quase se instalou, até eu dar de caras com a Vera no showroom do Seixal e ter ficado vidrada com as opções que me foram apresentadas, mas a minha decisão há muito estava tomada e assim nasceu o meu T1 no final de Dezembro de 2021. Optei por licenciamento, uma caminhada longa e difícil mas que a arquitecta Sandra com o seu profissionalismo, disponibilidade, dedicação e simpatia atenuou, a intervenção da Diana da área comercial foi também crucial e apesar da obrigação que uma empresa tem perante os seus clientes, é meu dever reconhecer com agrado e por isso deixar este meu testemunho e agradecimento a uma empresa portuguesa que funcionou bem, foi de confiança no cumprimento dos prazos e responsável pelo longo e stressante processo de licenciamento, sem essa ajuda e precisa colaboração de todas as intervenientes, teria desistido do meu fantástico T1. A todas e por ordem de contacto apenas, o meu enorme agradecimento à Vera do showroom, à arquitecta Sandra que tanto me aturou e também à Diana da área comercial que me prometeu e cumpriu, no dia dos meus 73 anos, o meu T1 foi colocado na Xitaca. Bem Haja Vera, Sandra e Diana.” Jose Miguel Paredes "Thanks for the professionalism. I recommend it 100%." Assis da Silva "Thanks for the professionalism. I recommend it 100%."

DiFF House with over 20 years of experience thinks and develops solutions for the fast, quality construction and the best price of wooden houses. CONSTRUCTION SYSTEM VISIT OUR SHOWROOM IN AMARANTE, SEIXAL AND FARO EVOLUTIONARY CONSTRUCTION SYSTEM At CASA DiFF we always think and develop solutions for fast, quality construction at the best price. It is of little use to have a cheap construction without quality, because after a short time the problems appear. At the same time, buying a big house is expensive and its maintenance costs a lot of money. Therefore, the solution is to buy a quality construction adapted to your needs at all times. It was in this sense that at CASA DiFF we developed an evolutionary construction system, which allows customers to start with a smaller model, for example a T1 ground floor, and over time and as the family grows, acquire more modules, reaching a T4 with two floors. DURABILITY AND MAINTENANCE A wooden house can last as long or longer than a brick house. To do this, just do a maintenance on the exterior woods every 3/5 years with a product for exterior finishing. The product gives the wood a beautiful appearance, enhances the particular characteristics of the wood, accentuating its texture and keeping the grain visible, it contains water-repellent and fungicidal agents that ensure the protection of the wood, its great elasticity allows it to adapt to the movements of the wood so that it does not crack or form bubbles. It guarantees maximum protection from solar radiation and its coloring is highly durable. It is very easy to apply, and low cost. At the same time, we also have materials (alternatives to wood) for exterior finishing, which do not require any type of maintenance. Consult us, and find out more about these and other finishes. MATERIALS The wood used is Nordic pine, since it is a noble wood, with high mechanical resistance, which has good natural conditions of thermal insulation and acoustic absorption. At the same time, it guarantees a final product with the finest finish and the possibility of different colors. By choosing a wooden house, you are choosing an ecological and healthy house. The wood used in our constructions comes from sustainable forests, in order to protect the forests and the environment. Our construction system also allows the use of alternative materials to wood in both the interior and exterior finishes. MOUNTING SYSTEM 1 Factory pre-assembled modules, transported and placed on site with crane truck, very fast assembly. SYSTEM 2 Factory pre-assembled panels, field-assembled kit. WALLS The walls are double composed of exterior wood, air gap, thermal/acoustic insulation, air gap again and interior finishing. Both the thickness of the walls and the level of insulation depend on the design, location and purpose of the building. Electric piping built into the walls. Excellent thermal, acoustic and structural behavior, as well as great strength resulting from the construction system. The construction process is based on the “male-female” fitting for the construction of the double walls. In this procedure we have a perfect fit between the pieces which allows the complete sealing of the walls providing greater comfort and safety. FAQs
