Description

Your Single Storey Rear Extension Project — A Practical Guide for Homeowners

Thinking about extending out across the back of your house?

Your Single Storey Rear Extension Project is an illustrated digital guide designed to help homeowners in England understand the decisions involved in planning and building a single storey rear extension.

Whether you’re exploring ideas or getting ready to speak to a builder, this guide helps you work through the project step by step.

What’s inside?

  • Permitted development rules: Understand the conditions that may allow a single storey rear extension without a planning application, including depth and height considerations, and when prior approval or a full application may be needed.
  • Planning your project: A clear, step-by-step journey from initial ideas through to construction.
  • Extension design: Consider layout, natural light, glazing, roof form, materials and how the new space connects to your kitchen and living areas.
  • Costs and budgeting: Work through the main costs, from foundations and structure to glazing, heating and finishes.
  • Drawings and approvals: Understand the role of architectural drawings, planning permission, Lawful Development Certificates and Building Regulations.
  • Building Regulations: Understand how Building Regulations apply to structure, foundations, drainage, insulation, glazing and ventilation, and how approval is obtained.
  • Choosing builders: Prepare for quotations and discussions with contractors.
  • Practical checklists and worksheets: Keep track of decisions, costs and next steps.

Important Information

This guide provides general information and practical project guidance. It does not assess the planning status of your specific property, confirm permitted development rights, replace professional advice or constitute planning permission, a Lawful Development Certificate or Building Control approval.

Planning restrictions and requirements depend on your property and proposed works. Check the applicable requirements before proceeding.

Before you buy
  • This package is for work that genuinely qualifies as Permitted Development. It is not planning permission and not a Lawful Development Certificate.
  • Building Regulations and Building Control approval are separate and still apply where relevant.
  • Structural engineering design and calculations are not included and must be provided separately by a qualified Structural Engineer where required.
  • Standard extension packages are designed as bolt-on additions. They do not include removing structural walls or forming large structural openings in the existing house.
