Extending your home is one of the most effective ways to create additional living space without the need to move.
At HEAMES Architectural Drawings & Planning Consultants, we provide professional architectural drawings, measured surveys and planning application services for house extensions across Cardiff and South Wales.
Whether you are planning a single-storey extension, double-storey extension or kitchen extension, we can guide you through the design and planning process from initial survey through to planning approval.

Types of Extensions We Design
We regularly design a wide range of residential extensions including:
Single Storey Extensions
Ideal for creating larger kitchens, open-plan living spaces or garden rooms.
Two Storey Extensions
A popular option for adding additional bedrooms, bathrooms and expanding ground floor living space.
Side Extensions
A great way to make use of unused space to the side of a property.
Rear Extensions
Often used to create larger kitchen or dining areas overlooking the garden.
Wraparound Extensions
Combining side and rear extensions to significantly transform the layout of a home.
Planning Permission for House Extensions
Many house extensions require planning permission, particularly if the extension exceeds permitted development limits or is located within a conservation area or on a listed property.
We prepare all of the drawings and documents required for the planning application and submit them directly to the relevant planning authority on your behalf.
With experience working with councils across Cardiff, Newport, Caerphilly, Bristol and North Somerset, we understand the policies and requirements that influence planning decisions.
Our Process
1. Initial Consultation
We discuss your ideas, assess the property and provide advice on what is possible.
2. Measured Building Survey
A detailed survey of the existing property is carried out to ensure accurate drawings.
3. Design & Drawings
We prepare existing and proposed architectural drawings showing the extension.
4. Planning Application
The planning application is submitted to the local authority along with supporting documents.
5. Planning Approval
Once permission is granted, we can also assist with building regulation drawings for construction.
