What is included in your extension drawing pack
Your pack is designed for council submission and clear assessment. We provide drawings that planning officers can review quickly and confidently, plus support to refine the proposal before submission.
Measured survey and existing drawings
Accurate existing plans and elevations are the foundation. Where needed we carry out a measured survey to produce reliable base drawings.
Proposed drawings for planning
Proposed floor plans and elevations to show what you are building, how it looks, and how it relates to the existing house.
Location plan and block plan
Standard plans required for planning submission to identify the site and its context.
Sections and roof plans where required
Where the extension affects height, roof form, or massing, we prepare sections and roof plans to make the proposal clear.
Revision support before submission
Most projects need refinement. We help you adjust layout, doors, glazing, and design details to strengthen the planning outcome.
Building Regulations pack available
After planning we can prepare Building Regulations drawings, suitable for Building Control and construction coordination.

Why house extension applications get refused in London
Many refusals happen because drawings do not communicate compliance clearly. A good design still needs drawings that demonstrate scale, neighbour impact, daylight, and the relationship to the existing building.
Excessive depth and overdevelopment
Extensions that push too far into the garden can be seen as overdevelopment. We design proportions that feel reasonable in planning terms.
Daylight and overshadowing impact
Councils focus on neighbour impact. We design with massing, projections, and glazing position in mind.
Scale, height, and roof form
Height changes can trigger refusal. We present roof design and massing so the proposal reads clearly and proportionally.
Poor justification and unclear drawings
If officers cannot quickly assess the proposal, risk goes up. We create clean, consistent drawings that are easy to review.
Planning officer reality
Officers are busy. They want clear drawings, consistent dimensions, legible elevations, and a proposal that shows you have considered neighbours and character. Our packs are built to reduce friction and increase confidence at review stage.
Types of house extensions we design
We work across London on terraced houses, semis, detached homes, and flats. We design extensions that match the property, reduce planning risk, and maximise usable space.
Rear extensions
Rear extensions are a popular way to create open plan kitchen and dining space. We balance internal gain with planning depth expectations, glazing placement, and neighbour impact.
Side return extensions
Side return extensions are common in Victorian houses. We maximise width and layout while respecting boundaries, daylight, and the overall character of the terrace.
Wrap around extensions
Wrap around extensions combine rear and side for major space gain. They need careful massing and strong presentation so officers can assess quickly.
Double storey extensions
Double storey extensions provide significant area but need sensitive scale control. We consider overlooking, roof relationships, and planning policy alignment.
Planning permission vs permitted development
Permitted development route
Some extensions can be built under permitted development, but you still need accurate drawings and careful rule checks. Many homeowners choose a Lawful Development Certificate for formal confirmation.
Full planning route
If your extension exceeds PD limits or your property has restrictions, full planning is required. We produce council ready packs and guide you through submission requirements.
