If you are planning a house extension, new build or loft conversion, you need to have a set of architectural floor plans. A good set of architectural drawings will help you visualise your project before you make any decisions about whether to go ahead or not. A simple concept package is recommended before you buy any new property because it helps you understand what is possible in the future.
If you know that you will be building within the next three years, you need to have a set of planning designs. These designs are required for planning permission or to get a lawful development certificate. Most projects require different floor plans and drawings for these applications. You may want to look into 3D floor plan software.
Existing Floor Plans
These floors plans are exact drawings of the building as it currently stands. The architect you hire will generally have someone conduct a measured survey of the property. However, it is possible to get these plans together based on existing drawings of the property.
The Design Floor Plans
As the name suggests, these are the floor plans of the design you are proposing. They will take into account your future needs, personal tastes and the planning regulations in your area. There are certain types of extensions that fall into permitted development rights, but you still need to apply for a lawful development certificate. This will prove that you had the right for the extension when you sell your home.
This is a vertical plan that shows the layout of the interior and exterior walls. The drawings will include kitchen cabinets and windows.
Building Regulation Drawings
After you have your planning permission, you need to have building regulation drawings. These drawings can be commissioned by an architect. They will provide more in-depth plans for where each element of the property should be placed and the materials that need to be used. This is what the construction crew will use as their guide when they produce their own drawings.
The Structural Drawings
Before building starts, you need to have a structural engineer look at the existing property and the plans. This will help with your structural drawings, which include information about the size and placement of reinforcements and the building materials needed.
These drawings will show all the wiring in the property from the placement of plug sockets to the lights. Everything on these drawings will need to be agreed with your electrician as early into the project as possible. While this might seem like a small detail, your wiring can become complicated and expensive if you have to make any changes.
The Plumbing and Sanitary Drawings
These drawings will layout where the pipes, bathroom fixtures and sanitation will be placed. They will have to take into account any finding that the CCTV survey has highlighted. This survey needs to be done before the project starts.
At some stage of your planning, you should consider investing in some 3D rendering. Doing this early is often better. While they are not construction drawings, they are useful if you want to use the plans to sell your home.
