A Practical Guide for Schools & Nurseries

If you're considering a modular classroom or nursery building, one of the first questions that comes up is:

“Do we need planning permission?”

The short answer?
Sometimes yes. Sometimes no.

But the real answer depends on your site, your local authority, and how the building will be used.

Here’s what schools and nurseries actually need to know.

When Planning Permission Is Usually Required

In most cases, permanent modular classrooms and nursery buildings will require planning permission.

This is especially true if:

• The building is intended for long-term use
  
  
• It increases pupil capacity
  
  
• It changes site layout or access
  
  
• It affects neighbouring properties
  
  
• The school is in a conservation area or green belt
  
  

Temporary buildings can sometimes fall under permitted development - but “temporary” doesn’t always mean what people think it means. Even 3-5 year installations may still require formal approval.

The key point:
Modular construction is treated the same as traditional construction in planning terms.

What Often Trips Schools & Nurseries Up

This is where projects slow down.

1. Assuming modular means “no planning needed”

Because the building is constructed off-site, some assume it bypasses planning. It doesn’t.

2. Not factoring in external works

Planning permission often hinges on:

• Groundworks
  
  
• Drainage
  
  
• Access routes
  
  
• Landscaping
  
  
• Parking changes
  
  

The classroom itself is rarely the only consideration.

3. Underestimating timeline

Even a straightforward planning application typically takes:

• 8 weeks for standard applications
  
  
• 13+ weeks for more complex cases
  
  

And that’s before build time is factored in.

How Long Does the Whole Process Take?

A realistic timeline for a modular classroom project looks like this:

Stage 1 - Feasibility & Concept (2-4 weeks)

• Site review
  
  
• Initial design
  
  
• Budget alignment
  
  

Stage 2 - Planning Application (8-13 weeks)

• Drawings submitted
  
  
• Consultation period
  
  
• Decision issued
  
  

Stage 3 - Technical Design & Building Regulations (4-6 weeks)

• Structural calculations
  
  
• Fire safety compliance
  
  
• Energy performance compliance
  
  

Stage 4 - Manufacture & Installation (6-12 weeks)

• Off-site construction
  
  
• Groundworks on site
  
  
• Delivery and installation
  
  

Because modular buildings are manufactured off-site, build time is significantly shorter than traditional construction - but planning remains the pacing factor.

What About Building Regulations?

Planning permission and building regulations are separate.

Planning permission considers:

• Impact on surroundings
  
  
• Use of land
  
  
• Visual appearance
  
  

Building regulations focus on:

• Structural safety
  
  
• Fire safety
  
  
• Accessibility
  
  
• Insulation and energy efficiency
  
  
• Ventilation
  
  

The good news?
If you partner with Eco Classrooms & Nurseries, we manage the full building regulations process on your behalf - including structural engineering and compliance certification.

That means schools and nurseries aren’t left navigating technical requirements alone.

Where RIBA Stages Fit In

Most modular classroom projects loosely follow the early RIBA Plan of Work stages:

• Stage 1-2: Brief and concept design
  
  
• Stage 3: Developed design (for planning submission)
  
  
• Stage 4: Technical design (for building regulations & manufacture)
  
  

Because modular construction is precision-engineered, technical design is finalised earlier than in traditional builds - reducing risk of mid-project surprises.

The Good News: Planning Isn’t a Barrier - It’s a Step

For most UK schools and nurseries, planning permission is entirely achievable and if you’re working with us at Eco Classrooms and Nurseries, we take complete care of planning permission for you. 

Local authorities are increasingly supportive of:

• Eco school buildings
  
  
• Energy-efficient modular classrooms
  
  
• Purpose-built nursery spaces
  
  
• Sustainable expansions
  
  

Especially where projects improve learning environments or early years provision.

The key is entering the process prepared - with compliant drawings, clear documentation, and a realistic timeline.

Final Thought: Start With a Site Assessment

If you're exploring:

• Modular classrooms in the UK
  
  
• Eco school buildings
  
  
• Modular nursery buildings
  
  
• Prefab nursery buildings
  
  

The first step isn’t submitting a planning application.

It’s assessing:

• Your site constraints
  
  
• Your local authority requirements
  
  
• Your projected pupil numbers
  
  
• Your long-term estate strategy
  

With the right groundwork, planning permission becomes predictable - not stressful.

That’s why choosing the right delivery partner matters.

At Eco Classrooms & Nurseries, we manage the entire planning process on your behalf. From initial site assessments and feasibility studies through to preparing and submitting the planning application, liaising with local authorities, and coordinating consultants, we take full responsibility for navigating the process.

Schools and nursery providers shouldn’t have to interpret policy documents or manage technical submissions themselves.

Our role is to make expansion straightforward - handling planning, building regulations, technical design and compliance from start to finish, so you can stay focused on running your setting.
