House extension design and drawing packages for UK homeowners, landlords and property professionals. Send the property address, photographs and a short brief for a free initial assessment and a fixed quotation before work begins.
Indicative house extension design and drawing packages fees
Packages start from £595. This is an initial guide, not a binding quotation. The confirmed fee depends on property size, complexity, survey information, design options and the required approval package.
Council charges, measured surveys, structural engineering, specialist reports and other third-party costs are excluded unless they are specifically included in the written quotation.
What your drawing package can include
Existing and proposed floor plans
Existing and proposed elevations
Roof plan and key sections where required
Design development for rear, side, wraparound and two-storey extensions
Planning or lawful-development drawing package where commissioned
A typical project example
For a typical single-storey rear extension, we can test the relationship between kitchen, dining space, daylight and garden access, then develop the selected option into coordinated plans and elevations for the agreed approval route.
A clear four-step process
1. Free initial project assessment
Tell us the address, property type, proposed work, timescale and what existing plans or surveys you have. We identify the likely scope and information gaps.
2. Written scope and fixed quotation
You receive a clear description of the drawings, design stages, revisions, exclusions, fee and expected programme before deciding whether to proceed.
3. Online design and review
The proposal is developed remotely using reliable survey information, photographs and your feedback. Draft drawings are reviewed with you before the package is finalised.
4. Issue and next-step guidance
The agreed drawings are issued digitally with an explanation of the next step. Planning permission, permitted development and Building Regulations are separate tests; the quotation states which stage is included.

Frequently asked questions
Can the service be completed online?
Yes, when suitable and reliable measured information is available. If a measured survey or site visit is needed, we explain this before design work begins.
Are revisions included?
The written quotation confirms the number and stage of included revisions. Additional work is never assumed and is quoted before it is undertaken.
Is approval guaranteed?
No designer can guarantee an approval. Decisions remain with the relevant council, building-control body or other authority. We prepare the agreed information carefully and respond to reasonable technical queries within the commissioned scope.
