How to Read Site Plans
By Meg Escott
In order to learn how to read site plans, let's look at what information you tin can look to see on a site plan.
This folio forms part of the how to read house plans series.
Nosotros're going to start out from the belongings line and gradually go through all the features on the site plan to build upwards to the final site plan with the location of the business firm shown.
- Property line
- Measurement basics
- Natural features
- Setbacks
- Easements
- Utilities
- Placing the dwelling on site
I'thousand going to employ some color to aid explain things merely many site plans are drawn in black and white.
I haven't used much text on the site plan to keep it ataxia costless. Unremarkably site plans will have a few explanatory notes on them to depict the features or buildings.
Property line
The property line is the purlieus of the site or lot with adjacent properties.
The site of our case report abode is a square shape.
It's important to learn how to read site plans in the wider context of the surroundings effectually the site. We can see the site here with the neigboring backdrop.
You lot can see how the belongings line is slightly set back from the street.
At the bottom right of the motion-picture show you can see some bluish. Permit'due south take that to be a small body of water which is a prissy view.

How to read site plans - measurement basics
There are a few basics that you'd expect to come across on the site plan.
Site plan showing the measurement basics - datum point, dimensions, elevation, scale and orientation
Datum point
The datum point is the identify on the plan to which all measurements on the program (dimensions and elevations) are referenced to.
Dimensions and pinnacle
The dimensions of the site are measured from the datum indicate and marked on the site plan.
The elevation (summit above sea level) is indicated at the datum indicate.
Calibration
The scale makes it possible to measure distances on the site. This becomes more of import when we commencement to put setbacks and easements onto the site plan (go along reading).
I've used a bar scale on our site plan. You may too come across the scale expressed numerically eg ane inch to 10 feet (one:120) or similar.
Orientation
It'south important to know the direction of Northward so that nosotros can determine where the sunday volition be shining.
Driveway
I forgot to mention that this site had a abode on it previously, so in that location is already a cut in from the street to the driveway.
Natural features
So now that we've got the nuts in place, information technology's time to move on to how to read site plans with any natural features such as a slope, trees and any bodies of h2o.
Site plan showing natural features - trees and slope
There's no ponds, or streams on the site itself.
The site backs onto some woods and besides has some copse more towards the front of the site which provide a scrap of privacy from the road.
There is a slight slope on the site. The gradient is mapped out using contour lines. Each contour line follows land that'due south the same elevation in a higher place bounding main level. You tin can meet that the elevation of each contour is marked.
To mark the contour lines, the surveyor will split up the site into say a filigree with squares every 20ft and will utilize an altimeter to record the meridian at each point on the grid. The contour lines tin so exist plotted.
An altimeter is just an instrument that can measure the acme above sea level. You can become an app for information technology on your phone if you're interested.
On our site program, the contours are marked off every human foot of elevation. The closer together the profile lines, the steeper the slope.
Setbacks
Setbacks are to do with the amount of space which must be left between the built structure and other places and features on the property such as the holding boundary, the street and natural features that need protection.
They're an important thing to look out for when yous're figuring out how to read site plans.
Setbacks are set up by the local planning department.
Let's look at the setbacks on our case study dwelling house.
Site plan showing set backs
- The orangish line shows these minimum set up backs from the belongings boundary. This might be a setback or an easement requirement. See easements beneath.
- The dark green line is the boundary of the woodlands which lie to the Northward of the property. Let'due south say the planning department imposes a woodland buffer. The light green line indicates the extent of this buffer. Y'all tin see how information technology reflects the shape of the woodland boundary.
- The burgundy dashed line shows the setback of the neighboring houses. This requirement is set past the planning department. You can run into the setback line for our site and the neighboring properties below.

Easements
An easement is a part of the land which the landowner owns but another party has the right to use information technology for a particular purpose.
In that location are some drainage easements on our case study site indicated by the blue arrows. Whatever is built on the site mustn't interfere with this drainage.

Utilities
A site plan should testify where access to services will be granted. This includes electricity, gas, h2o and sewers.
In our case study house the indicate at which the mains water can exist accessed is the blue dot, similarly for electricity (xanthous dot), gas (purple dot) and sewer drain (orange dot).
I estimate in this 24-hour interval and historic period it would besides be expert to include the internet as a utility.

Placing the home on the site plan
So now that we have learned how to read site plans, let's have a expect at the dwelling house placed on the site.
When all the setbacks are taken into account we tin see that the area of the site where building is commanded is not all that big. The majority of the site is in fact out of bounds for the house!
And then when we take into business relationship the area where edifice is immune, along with the views to the south east that we saw from the neighborhood site plan what is the all-time place for the house to exist placed?
Aa small sized dwelling house, faced towards the view can be placed in the position shown. Nosotros can see the roofline of the home, the driveway and an outbuilding to the east of the property.
Site plan with dwelling house placed on the site program
You may notice that the corner of the property overlaps the burgundy setback line. The view of the property from in a higher place shows the roof line. The interior of the home at the front end is set up back nether the roof to create a balustrade, and then in fact, there's no interior infinite that overlaps the setback.
Y'all'll be able to see that more than when nosotros look at how to read the flooring plan.
So, I promise that has taught you how to read site plans. This knowledge enables you to imagine what the house will be similar in information technology'south surround once it's built.
