2d Site plans is a simple outline of a buildings shape and size drawn as an overhead view of a building in relation to nearby roads, buildings, trees and other permanent features. It is a simple outline of each feature to help identify a buildings orientation in relations to nearby features and the sun for location of rooms or renewable technology, access to the plot during construction and during occupation, exposure to the wind and rain and location of utilities such as water and electricity. It’s also useful to identify land boundaries and can often include details about the rise and fall of the land.
2d floor plans are a great way to visualise a buildings layout, orientation and size from above. Often with room names or descriptions and the location of all fixed furniture, windows and doors. This information is useful for a multitude or applications. For example plans for a proposed renovation or new build project, fire safety plans, planning applications, marketing material, lease hold plans, licence plans and houses in multiple occupation (HMO) plans to name a few. Floor plans can be a simple map with no measurements, room extent measurements, detailed measurements in feet and metres or be drawn to scale with a scale bar depending on the desired use.
Elevations are a flat representation of the front, back and sides of the building designed to show the fall of the surrounding land, the ridge height and window heights not visible on the floor plan. It can also be useful to show the roof pitch and external features to gain an understanding of the exterior of the building. Elevations are useful to show the existing and proposed exterior of a building for renovation or redecorating projects and also for planning applications. They are an invaluable way to get ideas across to professional companies and trades people, weather to provide quotes or use in works.
A section is a cross section of a building and is useful to visualise the internal spaces, room heights, ceiling types and roof pitch. They can be packed with construction detail and are often used to display information not available on plans and sections such as material properties and thickness, details of window and door sills and lintels, floor and wall joints and roof spaces.
These are close up 2d plans of sections of the building that require extra detail to inform planners, builders and contractors. Often details such as the connection between the floor slab and walls, intermittent floors and walls, ceilings or roof and walls, the connection or vertical corners, window and door lintels, sill and jambs. These are often also packed with construction detail to show materials, thickness and thermal properties and are valuable tool to keep designs clear and easy to follow.
