Property Conversion

Home / Planning Services / Property Conversion

What is Property Conversion?

A property conversion involves transforming an existing space or building into a different functional use without building a completely new structure.

Common examples include:

  • Converting a loft into a bedroom

  • Converting a garage into a home office

  • Converting a house into flats

  • Converting a commercial building into residential units

Conversions are often faster, more cost-effective and more sustainable than building new structures.

At Planning Build, we ensure every conversion is designed to meet planning policies, building regulations and structural safety standards.

Do You Need Planning Permission For A Conversion?

Planning requirements depend on the type of conversion.

You may not need planning permission if the project falls under permitted development rights.

However, planning permission is usually required when:

  • Converting a house into flats

  • Changing building use (commercial to residential)

  • Extending beyond permitted development limits

  • Altering the external appearance significantly

Our team will assess your project and advise on the best planning strategy.

Our Planning & Build Process

We believe successful projects start with clarity. That’s why we follow a structured, transparent process from initial feasibility to final delivery.

Step 1: Planning Appraisal & Feasibility

At this stage, we assess:

  • Whether your proposed development is feasible

  • Whether planning permission is required

  • What type of application (if any) is needed

  • Estimated planning and consultant costs

  • Key planning risks and constraints

  • The overall likelihood of success

This early-stage assessment reduces uncertainty, minimises risk and ensures you make informed decisions before committing further time or investment.

Step 2: Design & Technical Preparation

If your project is viable, our team will guide you through the next stages.

We provide a fully integrated service including:

  • Architectural design

  • Planning permission applications

  • Building regulations drawings

  • Structural engineering coordination

  • Technical detailing

Our approach ensures that design, compliance and buildability are aligned from the outset, preventing delays later in the process.

Step 3: Application Submission & Management

Once your design is finalised, we prepare and submit all required documentation.

We:

  • Compile and submit your planning application

  • Liaise with the local authority

  • Respond to case officer queries

  • Manage amendments if required

  • Provide regular progress updates

You won’t need to chase the council; we handle everything on your behalf.

Step 4: Post-Approval & Construction Support

After securing planning approval, we continue supporting your project through:

  • Building regulations approval

  • Structural engineering integration

  • Construction coordination

Our goal is to provide a seamless transition from concept to completion.

Step 5: Ongoing Support & Communication

If you choose to instruct us, our experts manage the entire process for you.

You receive:

  • Clear timelines

  • Transparent advice

  • Regular updates

  • Direct communication with your dedicated consultant

We make the process straightforward, structured and stress-free.

Frequently Asked Questions

How much does planning permission cost?

Planning application fees vary depending on development type and scale. Local authority fees are set nationally, but consultancy fees depend on complexity.

Can I start building without planning permission?

No. Starting works without required approval can lead to enforcement action.

What happens if planning permission is refused?

You may revise and resubmit or appeal through the Planning Inspectorate within statutory time limits.
