Design-Led MVHR Installations for Architects and Developers

Architectural design and mechanical systems often conflict—especially when ductwork, grille placement, and access panels disrupt the aesthetic flow of a project.

But it doesn’t have to be that way.

At ClimateWorks, we help architects and developers across Hampshire, Berkshire, and Surrey deliver fully integrated MVHR installations that respect both performance and visual design.

This blog explains how design-led coordination delivers better MVHR outcomes, avoids late-stage redesigns, and keeps clients happy with the finished product.

What goes wrong with MVHR installations that aren’t design-led

MVHR systems often fall short because:

• Duct routes are an afterthought and clash with structure or lighting
• Grilles are placed in awkward or visible positions
• Access to filters or units is difficult or obstructive
• External terminals don’t match the façade materials or layout
• Performance drops due to excessive bends or poor airflow design

These issues usually stem from late involvement or lack of coordination.

We help prevent all of them with design-stage MVHR planning built around your layouts.

How we support architects and developers from concept stage

Our approach to design-led MVHR includes:

• Reviewing ceiling void depths and build-ups early
• Proposing grille positions that match the interior design
• Selecting semi-rigid or radial ducting to reduce space usage
• Providing grille and terminal finish options to match material palettes
• Routing extract and intake discreetly through existing service zones

We’ve done this on new builds in Guildford, conversions in Farnham, and extensions in Winchester—all without compromising the architect’s vision.

Local project examples from Hampshire, Berkshire, and Surrey

Guildford – Contemporary new-build

The architect specified clean ceiling lines and integrated lighting throughout. We proposed grille placements above cabinetry and selected radial ducting to reduce void depth. External terminals were colour-matched to the cladding and fully compliant with planning.

Reading – Loft conversion

In a retrofit with limited structural flexibility, we used compact semi-rigid ductwork and adapted grille locations to avoid clashing with beams. The MVHR unit was concealed in eaves storage with easy-access filters.

Winchester – Extension with open-plan living

This high-end extension needed consistent air quality without visible services. We designed the system to extract from concealed ceiling slots and supplied matched-finish terminals to blend into the new façade.

How we ensure compliance while supporting your design

ClimateWorks handles the technical side so you can focus on design. We:

• Ensure all airflow targets meet Approved Document F
• Optimise duct runs to reduce pressure drops and sound levels
• Select SAP-listed units to support your energy strategy
• Ensure grille locations are serviceable and Part F compliant
• Help you pass TM59 on overheating risk in relevant rooms

You get a fully compliant MVHR system—without compromising on layout, interior design, or finishes.

Our process for seamless integration

We follow a simple but rigorous process:

• Stage 2: Review architectural drawings and ceiling/floor layouts
• Stage 3: Provide indicative grille, duct, and unit locations
• Stage 4: Coordinate with structural, M&E, and interior consultants
• Stage 5: Finalise install drawings and product specifications
• Construction: Deliver, install, and commission with your build schedule

Every step is documented. Every detail is coordinated. Nothing is guessed.

Work with an MVHR partner who understands architecture

If you're designing homes, extensions, or conversions in Hampshire, Berkshire, or Surrey, we’ll help you install systems that:

• Are invisible to the end user
• Comply with all relevant performance and planning standards
• Fit seamlessly with lighting, joinery, and ceiling layouts
• Reduce install time and post-handover adjustments

You don’t need to sacrifice design quality to achieve ventilation performance.
