MMC Consultancy & Modular Build Advice

Cornwall, Devon & UK Projects

If you are exploring Modern Methods of Construction (MMC) but unsure which route suits your project, our consultancy service provides clear, practical guidance from day one.

We help you choose the right system — whether that’s a timber frame annex, a modular home, or a bespoke offsite solution.

We advise:

  • Property developers delivering multi-unit schemes

  • Architects designing high-spec, stylised homes

  • Homeowners planning extensions or annexes

  • Engineers, manufacturers and private clients

The Building with Frames Assessment Tool

Every project carries risks and opportunities. What appears simple on paper often becomes complex once logistics, lifting strategy and access are considered.

Using our Building with Frames Assessment Tool, we assess:

  • Structural system options

  • Delivery and crane access

  • Ground conditions

  • Unit size and weight

  • Cost implications

This ensures you understand the full picture before committing to a build route.

Site Appraisal & Modular Feasibility

We begin with a detailed site and product appraisal. Module size, weight and crane reach all depend on ground conditions, access routes and final position.

By addressing these factors early, we reduce risk, avoid redesign and protect your budget.

Early Stage Planning Saves Money

Engaging an experienced modular manufacturer at concept stage can prevent costly structural or logistical changes later.

A small adjustment in design at RIBA Stage 2 can save significant expense during manufacture and installation.

Offsite Modular Building

Define the Purpose of Your Modular Project

Every successful offsite modular build starts with clarity.

Spending time at the beginning of your project defining scope, performance requirements and design intent will save time and money later.

We ask simple but critical questions:

  • What problem is the building solving?

  • What performance level do you require?

  • Are there bespoke or architectural features to incorporate?

  • Will access or lifting constraints affect design?

Early discussion, idea testing and problem-solving form the foundation of a successful modular project.

Why Early Planning Matters

Small design decisions can significantly affect cost and logistics.

For example:

  • Modules wider than 3.5m require a transport attendant, adding £500–£1,000 per delivery.

  • If modules cannot be doubled up on one lorry due to length, transport costs increase.

  • Tight site access or turning circles may require alternative trailer configurations.

We also assess:

  • Crane size and lifting radius

  • Ground conditions

  • Structural engineering for manufacture, transport and final position

  • Whether the building may need relocating in the future

We address these factors through detailed site appraisals, ensuring no surprises once manufacturing begins.

Projects We Support

We consult on a wide range of modular and timber frame projects, including:

  • Annexes for family accommodation

  • One-bedroom homes

  • Multi-modular housing

  • Holiday park units

  • Commercial and workspace extensions

Whether you are adding space for a relative or expanding a business, we provide practical, experience-led guidance to help you make informed decisions.

Many consultations progress into full Building with Frames projects. However, our priority remains the same: ensuring you select the right construction route for your needs.

Areas We Cover

We primarily deliver modular construction consultancy in Cornwall and Devon, where we have built a strong regional reputation.

We also support projects across the UK following an initial online consultation.
