A dream home starts from the scratch, a plan that decides its designing pattern, structural solidity and functional potential. The reason why planning drawings are made prior to the start of a project is because every locality has a line of rules and that needs to be abided by every builder and contractor. Any sort of violation will legally enforce an immediate redesigning of the structure.
However, plan drawings are not just about creating a unique design for a home, but also keeping the measurements correct so that construction and sustainability of the same are not hampered because of the architectural design. Versions of software like Auto Cad designed for home computers are often used to sculpt models of homes as plan presentations in 3D.
An expert designer conducts research by approaching the owners of the adjoining houses to ask if they have any objection against the proposed plan. Taking their suggestions and responses into account, the plan is modified at the budding stage so that later complications do not arise.
Though design inputs are both contributed by the designer and the owner, it is important to keep the plan in sync with the rest of the houses in the block. However, this does not mean that you cannot include originality in your drawings. Synchroneity with the rest of the neighbourhood is necessary because of directional and dimensional parity with the existing premises in the plot. Other things affecting a plan drawing are access systems, homestead positions, boundary treatments, level of ground, flooring, ceiling, storeys, etc.
