House Extension Plans & Extension Drawings
A clear architectural package for understanding and developing your home extension.

Clear scope.
Useful output.
For homeowners using UK-style search language, Artimist develops existing and proposed drawings for house extensions while keeping the professional boundary clear: we provide remote design and documentation support, and locally required planning, building-regulations, structural and licensed-professional responsibilities remain with the appropriate local parties.
Homeowners planning rear, side, side-return or multi-storey extensions and builders or local professionals who need additional architectural production support.

Where we become useful.
- The extra space is needed but the extension layout and connection to the existing house are unresolved.
- Existing and proposed drawings are needed to explain the scheme clearly to local professionals.
- Roof, openings, circulation and exterior form need to be coordinated before the project moves further.
Existing home / extension / proposed elevationWhat can be included.
- Existing and proposed architectural drawing package
- PDF issue set
- DWG or Revit files where included
How the project moves.
Selected visuals illustrate the stages; they are not a single-project before-and-after sequence. Concept studies are not issued construction documents.
01Understand the existing property
We start from reliable existing information and the space you are trying to gain.
02Develop the extension
Plan, circulation, openings, roof and exterior form are resolved as one design rather than separate drawings.
03Coordinate for local review
The agreed architectural package is prepared for review by the relevant local planning, building-control, engineering or licensed-professional team as applicable.
Explore the work in context.
Useful answers.
Do you provide planning drawings?
We can prepare architectural drawings for review and use within the local process, but the exact submission route and professional responsibilities depend on the property and authority and should be confirmed locally.
Can you design a rear or side-return extension?
Yes, provided reliable existing information and the relevant constraints are available.
Do you provide structural calculations?
Not as a default architectural service. Where structural engineering is required it should be handled or reviewed by an appropriately qualified local professional.
Can you show the extension in 3D?
Yes. Exterior and interior visualization can be included to make massing, daylight, materials and the connection to the existing house easier to judge.
Send what you have.
We’ll find the next move.
A plan, model, survey or rough brief is enough to begin.
