AN INTRODUCTION / 06
More room begins with a clear purpose.
An extension is an addition to an existing home, not a blank piece of land.
How you use the space, how the existing property is arranged and the constraints of the site all matter. Different extension types create different relationships between internal rooms, garden space, access and the original building.

Extension options for different homes.
These five confirmed extension categories give homeowners different ways to think about additional space, while property-specific feasibility still determines the appropriate scope.
02 / 05HOUSE EXTENSIONS
Double-Storey Extensions
An extension category affecting more than one level, where structural and site considerations may be more involved.

ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
From a spatial goal to a project conversation.
Use these stages to frame an extension enquiry without assuming architectural design, structural engineering or planning management is included.
- STAGE / 0101 — 0401
Describe the space you need
Explain how additional room could change day-to-day use of the home.
- STAGE / 0202 — 0402
Consider the property and site
Think about the existing building, available footprint, access and known constraints.
- STAGE / 0303 — 0403
Explore extension options
Review which confirmed categories may be relevant to the broad project brief.
- STAGE / 0404 — 0404
Clarify scope and next steps
Identify outstanding feasibility and specialist questions before proposed work is defined.
WHY CHOOSE RAPTOR / WHAT MATTERS
An extension needs to work with the home it joins.
A good project discussion considers both new space and the existing building.
Existing-property context
Layout and condition can influence where and how additional space is considered.
Roof and building interfaces
Connections between old and new construction are relevant to project scope.
Clearly defined questions
Access, use and constraints are worth discussing before assuming a specific design.
INSIGHT / FOOTPRINT / LAYOUT / CONNECTIONS
Choosing the shape of additional space.
The extension category is a starting point for exploring how new floor area relates to the current home.
Rear, side and wraparound additions
Rear extensions develop space behind a home; side extensions consider the available area alongside it. Wraparound configurations combine more than one direction. Each concept has different implications for site access, boundaries, existing rooms and the remaining outdoor area.
One storey or more?
Single-storey and double-storey additions offer different ways of approaching space. Additional levels may raise further structural, privacy and access considerations. A two-storey illustration is not proof that a particular building or site can accommodate such work.
A connection, not a separate object
Foundations, roof junctions, services, daylight, circulation and the existing building fabric can affect extension scope. Some projects may require designers, engineers or statutory approvals. The responsibility for those services must be confirmed, not inferred from the extension category.

QUESTIONS / HOUSE EXTENSIONS
Questions about extensions.
Common questions about extension types, constraints and early project information.
ASK ANOTHER QUESTION01How do rear and side extensions differ?
They describe where additional space sits in relation to the existing home. Their suitability depends on the property layout and site.
02When might a double-storey extension be considered?
It can be explored when additional space is being considered across more than one level, but structural and regulatory factors may influence feasibility.
03What does a wraparound extension mean?
It generally describes an addition extending around more than one side of the existing property. The actual configuration varies.
04Might planning permission be required?
Depending on the proposed work and property, statutory permissions or assessments may apply. No approval outcome or application-management service is being promised.
05What site factors matter before considering an extension?
Available space, access, the original structure, boundaries and connections between old and new construction may all affect the project.
06What information is useful for a first enquiry?
Your property area, a description of the existing home, the type of extension considered and your intended use for the new space are useful.
