Custom Modular Systems
Custom Modular Systems are designed-to-brief modular buildings for when ISO layouts are not enough. Therefore, you get more architectural freedom, upgraded finishes, and purpose-built compliance for your sector.
What are Custom Modular Systems?
Custom Modular Systems are modular buildings designed around your brief, rather than a fixed module catalogue. As a result, you can specify façades, glazing, internal layouts, and performance targets with much more flexibility.
In practice, they are chosen when you need a stronger architectural outcome, unusual room schedules, or sector-specific compliance. For example, this suits clubhouses, restaurants, education buildings, medical rooms, and permanent offices.
However, if you need the fastest, standardised route, ISO Frame Systems may be the right first step. Therefore, we include an ISO vs Custom comparison below.
Best for — custom modular use cases
Custom Modular is ideal when the building must look and perform like a “real building”, not a temporary cabin. Moreover, it suits branding-led projects and permanent estate planning.
Clubhouses & Sports Pavilions
Reception, changing rooms, bar/servery, terrace viewing, sponsor branding and higher-end finishes.
Hospitality: Café / Restaurant / Bar
Kitchen back-of-house, counter service, seating layouts, and robust washable interior finishes.
Education & Community Buildings
Permanent classrooms, SEN spaces, meeting rooms, and multi-room layouts designed to brief.
Medical / Clinics
Consult rooms, triage spaces, accessible entries, and cleanable hygienic wall systems.
Premium Offices & HQ Annex
Boardrooms, reception, acoustic upgrades and façade designs aligned to your brand.
Retail & Sales Suites
Showroom layouts, glazed frontages, and fast deployment on commercial sites.
ISO Frame vs Custom Modular — which should you choose?
If speed and standardisation matter most, ISO can be perfect. However, if architecture, layout freedom and permanence matter, Custom Modular is usually the better fit.
| Decision factor | ISO Frame Systems | Custom Modular Systems |
|---|---|---|
| Best when | Fast, repeatable layouts; standard modules; temporary / site deployment. | Architectural finish, bespoke layouts, sector-led compliance, permanent / semi-permanent. |
| Façade freedom | Limited to standardised options. | High — cladding, glazing, branding, feature elevations. |
| Room schedules | Standard room patterns. | Designed to brief (e.g., clubhouses, restaurants, clinics). |
| Long-term estate planning | Possible but more standardised. | Optimised — better for “real building” permanence and user experience. |

Custom Modular specification — what you can control
Custom Modular is specified around your goals. For example, you can prioritise acoustics, energy performance, durability, or appearance. Therefore, the quote pack confirms final build-ups.
Façade & external finishes
Choose cladding profiles, colours, glazing rhythm, feature elevations and brand-led detailing.
Thermal / energy strategy
Optimise insulation, airtightness, and HVAC selection for long-term use and comfort.
Fire & accessibility
Align to building use with fire strategy assumptions and accessible routes/doors/WCs where required.
Interior finish packages
