Are you planning a loft conversion, house extension, or a new build? Regardless, you are bound to start with a set of floor plans. These are basically drawings showing a view of the relationships between spaces, rooms, traffic patterns, etc., at one level of structure. These plans help you visualise the project way before you decide whether or not you want to go ahead with the construction. In fact, this is something you should invest in using Four Labs or similar, before purchasing property as it helps you comprehend what’s possible for your home in the future.
If you intend to build in the next 2 to 3 years, then you need a set of plan designs in order to apply for a lawful development certificate or planning permission. For most construction projects, you will require the following drawings in order to apply for planning or development authorisation.
Existing Floor Plans
These are precise floor plans of what the structure currently looks like. Your architect or designer should appoint someone to perform a measured survey of the property. However, it’s possible to assemble these plans from existing drawings in some cases.
Design Floor Plans
These are drawings for your intended design. These plans take into consideration the planning regulations in your region, your preferences and future requirements. Some forms of house extensions fall under permitted development rights, but you will still need to apply for a lawful development certificate so that when it comes to selling, you will have proof that this was the case.
These are vertical drawings that present the layout of the interior and exterior walls. Once you have secured your planning permit, building regulation drawings become the most crucial type of building plan. They give an in-depth plan for where every element should go and the materials to be used. You can commission these plans from your architect, which will then be used by the construction team to create drawings such as:
Before the project begins, you will want a structural engineer to look at the proposed plans and existing property plans as well. This will help them provide structural drawings, which are essential for giving details on the building materials, size, and placement of reinforcements.
Plumbing and Sanitary Drawings
These drawings give the layout for all the pipes, bathroom and sanitation fixtures and take into account any CCTV survey findings (usually conducted before construction begins).
These represent all the electrical wiring, including the placement of inbuilt lights and plug sockets. Ensure you agree to all of this with the electrician in the early stages of the project, as even though they might seem to be a small detail, they can be time-consuming and expensive to change later on.
Last but not least, at any planning stage, consider investing in 3-dimensional renders. These are not really considered to be construction drawings, but they really come in handy when visualising the final product. Also, due to the fact that they bring the finished product to life, they make selling a property a bit easier.
