The purpose is to understand the planning process for residential buildings and toinvestigate the consequences of the choices made in the process. The project will alsoprovide broader knowledge in the design and development under the current law andpractice.The goal is to present a proposal on how a city near the site where water can bedesigned from a sustainable perspective. How can a residential neighborhood be anenvironmentally sound and sustainable region? New systems and techniques havebeen presented previously in terms of sustainable environments and these are intendedof being used in the project Quarter Water-mirror.The project has been implemented on the computer program ArchiCAD in whichdrawings and visualizations have been carried out. These drawings are included asannexes to the report.For information, calculations and drawings, laws for physical planning and Swedishstandard have been followed.Residential buildings have been designed on a site, which is 2, 5 hectares. This area isexploited to a large extent, have generous space and environmentally friendlyachievements. The sustainable development of the area is supposed to contribute tolong-term management. To create an attractive and interesting environment, a channelhas been incorporated into the field.In the planning has availability, guest/ private parking, infrastructure and in the land,the farm formations, water and solar studies taken into account where the Planningand Building Act has been a starting point.Apartments have been presented with regard to the functioning, transparency andlight. When these factors were crucial in the case of a well-resolved data.The investigations made that refined solutions, including waste disposal, diversion ofwater, etc. existed. These methods will not necessarily be used in Quarter Watermirrorbecause nothing is elucidated. However, these solutions are good practice togive the area a sustainable environment.
