All house plan drawings should contain title block information. You can expect to see a title block on site plans, floor plans, elevations, and sections.
This page forms part of the how to read house plans series.
Title block information is generally placed in the bottom right hand corner of drawings and can be in a portrait or landscape layout depending on what fits better.
I'm not going to state the obvious and go through each piece of information in detail but I want to point out a few things.
The scale is really important to enable you to work out the real size of the parts of your home that the drawings represent.
The scale and size of the paper should both be indicated. If you get the same drawing on a smaller size of paper, the scale will be altered.
In the examples on this page the scale is for 1/4 ins represents 1ft or 1:96 and ArchE refers to a standard US architecture paper size.
In countries which use the metric system you can expect to see something like 1:100 @A0 meaning a scale of 1cm represents 1m on size A0 paper.
Sometimes there might be two sets of information to allow for printing on two different paper sizes.
Contact details are important. If you are designing your own home you won't need both the client and architect sections. Make sure the contact details (including phone number and email) of the person that can be contacted about any questions. These drawings will be used by you (the homeowner), your planning officer and your contractor and any other people involved in your project.
Note that the clients full contact details are not given. If, as a client, you are applying for approval or dealing with your contractor without an architect, then put your phone number and email into the title block.
Site details are also essential to show where you intend to build the home on your plans.
The main purpose of this group of title block information is to enable your architect or draftsperson to stay organised.
The draw and check boxes refer to who drew and checked the drawings. The revision box shows how many times the drawing has changed. Some architects will also maintain a revisions block to document what revisions are made each time.
The project and drawing numbers are just for organisation.
Architects and other design professionals develop their own style of drawings and title block information so your title blocks will probably not look the same, or have the same order of information as above, but they should contain the same information.
