House extension drawings in Essex and Kent.
From drawings of the house as it is to planning approval and building regulations, we draw extensions that work for the house you have and the way you want to live in it.
For homes in England. Requirements depend on the property and your local council.
What we draw.
Every extension starts with an accurate record of the house, then a design you can see and discuss before anything is submitted.
- Existing plans and elevations of the house as it is now.
- Existing and proposed plans, elevations and sections showing exactly what changes.
- The planning application, prepared and submitted on your behalf.
- Building regulations drawings and specifications for building control and your builder.
- Interior layouts and visualisations, if you want to see the finished rooms first.
Planning or permitted development?
Some single-storey extensions can be built under permitted development, without a full planning application, as long as they stay within limits on depth, height and materials. Flats, listed buildings and many conservation areas are excluded, and some councils have removed these rights in particular streets.
Everything else needs a householder planning application. Either way we confirm the route first, so you are not paying for drawings you do not need.
Government guidance: making a planning application.
Your local council.
Planning applications go to the council for the area your home is in. For example:
- Billericay, Wickford and Basildon
- Basildon Borough Council
- Brentwood
- Brentwood Borough Council
- Chelmsford
- Chelmsford City Council
- East Tilbury and Grays
- Thurrock Council
- Maidstone
- Maidstone Borough Council
Each council publishes its own validation checklist and local design guidance. We prepare the drawings to match.

Common questions.
Do I need planning permission for an extension?
Not always. Some single-storey extensions fall under permitted development, within limits on size, height and materials. Others, including most two-storey extensions and work on flats or in many conservation areas, need a householder planning application. We check which route applies before drawing anything.
How long does a householder application take?
Councils aim to decide householder applications within eight weeks of validating them. Preparing the drawings comes first, and any changes the planning officer asks for can add time.
Do I need building regulations drawings as well?
Yes, for almost all extensions. Planning approval covers how the extension looks and its effect on neighbours; building regulations cover how it is built, from foundations and insulation to drainage and fire safety. We prepare both sets.
Does the Party Wall Act apply?
It can, if the work is on or near a shared wall or boundary, or involves digging foundations close to a neighbour’s. If so, notices need to be served on the neighbours before work starts.
