Mobile Homes vs Static Cabins: B2B Dealer Comparison Guide
Mobile Homes and Static Log Cabins: Understanding the Market Distinction
The timber structure market across the UK and Europe is divided into two fundamentally different product categories: mobile homes (also known as park homes or residential caravans) and static log cabins (fixed timber buildings). While both are manufactured from timber and both can be specified for different project and commercial contexts, they operate under entirely different regulatory frameworks, serve different market segments, and require different sales approaches from dealers and distributors.
For B2B partners evaluating their product portfolio, the distinction between mobile and static timber structures determines everything from planning permission requirements to transport logistics, installation methods, and end-customer expectations. Dealers who understand both categories, and can advise their customers accordingly, hold a significant competitive advantage in the timber building market.
This comparison guide examines every aspect of mobile homes and static log cabins from a dealer perspective: legal definitions, construction specifications, market applications, business economics, and supply logistics. The objective is to equip B2B partners with the technical and commercial knowledge required to position both product lines effectively.
Definitions and Legal Framework
What Qualifies as a Mobile Home?
In the United Kingdom, the legal definition of a mobile home derives from the Caravan Sites Act 1968 (as amended). A structure qualifies as a mobile home (legally termed a “caravan”) if it is designed or adapted for human habitation, is capable of being moved from one place to another by being towed or transported on a vehicle, and does not exceed the prescribed maximum dimensions.
The maximum permitted dimensions for a twin-unit mobile home are 20 metres in length, 6.8 metres in width, and 3.05 metres in internal height (measured from the floor surface to the ceiling at the highest point). Initial-order structures share the same length and width limits. These dimensions are important for dealers to communicate accurately because exceeding them can change the classification route and trigger project-specific planning, building-control, or local authority review.
The transportability requirement does not mean the structure must be regularly moved. It means the structure must be capable of being moved by road, either as a initial order or in no more than two sections. In practice, most timber mobile homes are transported to site once and remain in position for decades. The legal classification relates to capability, not intent.
Across Europe, equivalent definitions vary by jurisdiction. Germany uses the term “Mobilheim” with different dimensional standards. France classifies “résidences mobiles de loisirs” under specific tourism legislation. Dealers operating in multiple markets must verify local dimensional and classification requirements before listing products.
What Is a Static Log Cabin?
A static log cabin is a permanent timber structure erected on foundations and intended to remain in position indefinitely. Unlike mobile homes, static cabins have no legal requirement for transportability and no dimensional restrictions imposed by caravan legislation. They can be specified in a wider range of sizes and configurations, with final suitability reviewed against the client brief, site conditions, and local requirements.
In the UK, static log cabins should be reviewed against the intended use, site context, and local planning route. Where a project is intended for regulated use, the client design team or building-control body must assess the full design, including structure, fire safety, energy performance, ventilation, accessibility, and services. Foundation requirements depend on ground conditions but generally involve concrete slab foundations or strip foundations designed by a structural engineer.
The absence of dimensional constraints gives static log cabins significant design flexibility. Wall thicknesses can range from 28 mm for simple garden storage buildings to thicker insulated specifications for higher-performance project briefs. Floor plans are unconstrained by transport width limits, allowing L-shaped layouts, integrated garages, mezzanine floors, and multi-storey construction.
For dealers, the key distinction is this: mobile homes operate within a defined regulatory framework that simplifies the planning process but constrains the product specification. Static cabins offer unlimited specification potential but require the end customer to navigate a more demanding approval process.
Regulatory Comparison
| Criterion | Mobile Home | Static Log Cabin |
|---|---|---|
| Planning Permission | Site and use dependent; licensed-site, planning, and local authority review may be required | Planning route depends on size, site, intended use, and local authority review |
| Building Regulations | Classification and standard requirements depend on intended use, site licence, and project documentation | Building-control or local authority review required where the intended use is regulated |
| Maximum Dimensions | 20 m × 6.8 m × 3.05 m (twin-unit); legally defined | No legal maximum; determined by planning approval and site constraints |
| Foundation Requirements | Bearer system or levelled hard-standing, confirmed against site and project requirements | Concrete slab or strip foundations; structural engineer specification recommended |
| Site Requirements | Licensed caravan site, agricultural holding, or site with specific mobile home permission | Approved site context, subject to intended use and local authority review |
| VAT Treatment (UK) | Potential treatment depends on HMRC criteria and accountant review | Standard-rated (20%) for kit supply; reduced or zero rate may apply for new-build dwellings with specific conditions |
| Insurance Classification | Specialist park home/caravan insurance; typically lower premiums | Insurance route depends on site, use, and insurer requirements |
| Resale Considerations | Depreciating asset; value linked to site licence and condition | Appreciating asset (with land); value linked to property market |
The VAT treatment is particularly significant for UK dealers. Mobile homes qualifying as residential caravans under HMRC Notice 701/20 are zero-rated for VAT purposes, which can represent a substantial cost advantage for the end customer. Dealers should consult with their accountants to confirm eligibility for each product configuration, as HMRC applies specific criteria regarding dimensions, transportability, and intended use.
Construction and Specification
Both mobile homes and static log cabins are manufactured from northern European spruce using CNC precision cutting technology. However, the construction methodology differs significantly between the two product types, driven by the fundamentally different requirements of transportability versus permanence.
Mobile home construction centres on the chassis and bearer system. Glulam floor bearers (typically 88 mm engineered timber) form the structural base, designed to distribute loads evenly across the transport chassis and site bearers. Wall construction uses 88 mm solid or glulam timber as standard, providing a balance between structural integrity, thermal performance, and weight management for road transport. The roof structure must accommodate transport stresses including wind loading and road vibration, requiring engineering specifications that account for dynamic as well as static loads.
Static log cabin construction uses conventional interlocking log wall systems without transport constraints. Wall thicknesses range from 28 mm (small garden buildings and storage) through 44–70 mm (garden offices and leisure cabins) to 88–220 mm (twin-skin insulated structures for higher-specification project briefs). The absence of weight and width restrictions allows thicker walls, larger roof spans, and more ambitious architectural designs including multi-level construction, integrated verandas, and complex roof geometries.
Both product types share common quality elements: precision CNC cutting on Hundegger machinery, kiln-dried timber processed in Nardi kilns (12–15% moisture content), double or triple glazing options, and stainless steel hardware. The quality differential between mobile and static is not a matter of manufacturing standard but of engineering optimisation for different end-use scenarios.
For dealers, this means both product lines carry equivalent manufacturing credibility. The specification differences reflect functional requirements, not quality tiers.
Transport and Installation
Transport logistics represent one of the most significant operational differences between mobile homes and static cabins, with direct implications for dealer margins, lead times, and customer experience.
Mobile home transport involves delivering a fully assembled or semi-assembled structure by road. Twin-unit mobile homes are transported in two halves and joined on site. The maximum transport width of 6.8 metres requires wide-load permits and escort vehicles in most European jurisdictions. In the UK, loads exceeding 3.0 metres in width require notification to the relevant highway authority, and loads over 4.3 metres require police escort. Route planning must account for road restrictions, bridge heights, and turning radii. Delivery typically requires a specialist haulage company experienced in mobile home transport.
Static cabin delivery uses conventional flat-pack logistics. Wall logs, roof boards, floor joists, windows, doors, and hardware are palletised and delivered by standard curtain-side or flatbed vehicles. No wide-load permits are required. A typical 40–60 m³ cabin occupies one standard truck load. Larger residential buildings may require two loads. On-site assembly requires a team of 2–4 experienced installers working for 3–10 days depending on size and specification. Crane hire may be necessary for structures with heavy glulam beams or pre-assembled roof trusses.
The installation model differs accordingly. Mobile homes arrive substantially complete, internal fixtures, kitchens, and bathrooms can be factory-installed. Site work involves levelling, connection to services (water, electricity, drainage), and joining the two halves for twin-units. Static cabins require full on-site assembly from component parts, including wall erection, roof construction, window and door fitting, and all internal finishing.
For dealers managing customer expectations, this distinction is fundamental. Mobile home customers expect a rapid, low-disruption installation process. Static cabin customers should be prepared for a construction project, albeit one using pre-cut, precision-manufactured components that significantly reduce on-site time compared to conventional building methods.
Market Applications
Mobile Home Market Segments
The mobile home market serves several distinct customer segments, each with specific requirements and purchasing patterns that dealers should understand.
Holiday parks and leisure operators represent the largest volume segment. Park operators purchase mobile homes for rental fleet replacement and expansion, typically ordering multiple units annually. These buyers prioritise durability, ease of maintenance, and attractive design that commands premium rental rates. Holiday park operators usually require documentation for the relevant park licensing and project-review process, and often specify particular colour schemes, layouts, and specification levels to match their brand positioning.
Residential park home site projects require careful review of site licence, intended use, specification, documentation, and local requirements. Higher specification may be expected, including insulation, heating, kitchen, bathroom, and service details confirmed by the project team. This segment commands higher unit values and longer sales cycles.
Agricultural and rural projects may use mobile units for staff or operational requirements where the planning route and site context support that use. The agricultural tie creates a specific market niche that dealers can serve with appropriately specified products.
Temporary and transitional housing is an emerging segment where mobile homes provide interim accommodation during property renovation, insurance claims, or relocation periods. This segment requires rapid deployment capability and flexible specification.
Static Cabin Market Segments
The static log cabin market addresses a broader range of applications, from small garden buildings to substantial residential properties.
Garden offices and home studios have driven significant market growth since 2020. These structures typically range from 10–25 m³, require insulation for year-round use, and often fall within Permitted Development rights, simplifying the sales process for dealers.
Higher-specification timber projects represent a high-value segment. Log homes and glulam houses require project-specific design, technical documentation, structural review, and local approval before any final use claim is made.
Hospitality and leisure projects combine the appeal of timber construction with commercial-use briefs. Dealers should keep final marketing, planning, and rental-use claims within the client project team and local authority review process.
Ancillary-building projects can require detailed local review because use, services, size, and site relationship affect the approval route. Dealers should frame these as project-specific briefs rather than automatic permitted uses.
Energy Performance and Project Review Standards
Energy performance is a project-review topic for both mobile homes and static cabins. Eurodita can provide technical data for wall thickness, timber specification, glazing, insulation options, and supplied components, but final suitability is assessed by the dealer, project designer, certifier, building-control body, or local authority.
Preliminary wall/log thermal data should be treated as element-level information, not whole-building compliance. The attached Eurodita thermal-resistance document lists preliminary wooden wall/log values such as 44mm at approximately 2.43 W/m²K, 70mm at approximately 1.53 W/m²K, 88mm at approximately 1.22 W/m²K, 180mm at approximately 0.59 W/m²K, and 220mm at approximately 0.49 W/m²K. These values do not replace a full envelope calculation.
Mobile home specifications can be developed around the client project brief, including insulation, glazing, ventilation, services, and transport requirements. Where a market requires BS 3632 or another residential-park-home standard, the project team must confirm the complete specification, test evidence, documentation route, and local approval requirements.
Static cabin specifications span a wider range, from seasonal garden buildings to higher-specification insulated structures. Twin-skin construction can support improved thermal performance because it combines two timber wall layers with an insulated cavity, but final U-values depend on the full wall build-up, floor, roof, glazing, air tightness, ventilation, installation quality, and calculation method.
For dealers, the practical message is simple: use Eurodita technical data to support customer and project review, but avoid presenting any wall figure as a finished-building compliance guarantee. Local authority review, designer sign-off, and project-specific calculation remain required where a structure is intended for regulated use.
Dealer Business Case
The commercial proposition for dealers differs significantly between mobile homes and static cabins. Understanding these differences enables B2B partners to build a balanced product portfolio that maximises both revenue and margin.
Order values: Mobile homes typically represent higher individual order values than static cabins. A fully specified 3-bedroom timber mobile home commands a significantly higher unit value than a garden office or standard leisure cabin. However, the static cabin range spans a wider value spectrum, from entry-level garden buildings to larger higher-specification timber projects that can exceed mobile home values. Dealers offering both product lines capture revenue across all price points.
Sales cycles: Mobile home sales often involve longer decision-making periods, particularly for park operators purchasing fleet replacements. Budget cycles, site licensing considerations, and seasonal factors influence timing. Static cabin sales range from rapid decisions (garden offices, garden rooms) to extended consultations (higher-specification timber projects requiring planning, design, and local authority review). A diverse product line stabilises revenue across seasonal and cyclical variations.
Repeat business: Holiday park operators purchasing mobile homes represent high-value repeat customers, typically replacing or adding units annually or biannually. Static cabin sales tend toward one-time purchases per customer, though satisfied customers generate referrals and reviews that drive new enquiries. Dealers should maintain relationships with both customer types through different retention strategies.
After-sales requirements: Both product types require warranty support and occasional maintenance guidance. Mobile homes may require periodic re-levelling, external treatment, and chassis inspection. Static cabins require timber treatment, roof maintenance, and settlement monitoring during the first 12–24 months. Dealers who provide structured after-sales programmes build stronger customer loyalty and command premium positioning in their market.
Market trajectory: Both segments show growth. The UK mobile home market benefits from housing affordability pressures and the expansion of holiday park accommodation. The static cabin market benefits from remote working trends, the garden office phenomenon, and increasing interest in timber as a sustainable construction material. Dealers positioned in both segments benefit from diversified growth drivers.

Frequently Asked Questions
What is the maximum size for a mobile home in the UK?
Under the Caravan Sites Act 1968 (as amended), a twin-unit mobile home must not exceed 20 metres in length, 6.8 metres in width, and 3.05 metres in internal height. Initial-order structures share the same length and width limits. Any structure exceeding these dimensions may move into a different classification route and should be reviewed by the relevant project professional, local authority, or building-control body.
Do mobile homes need planning permission?
Mobile homes sited on licensed caravan sites or park home sites are usually reviewed within the site licence and local planning context. However, creating a new caravan site requires planning permission, and siting a mobile home on private land outside a licensed site may require planning permission depending on the intended use and local planning policies. Agricultural and forestry uses may have specific routes, but these should be confirmed locally. Dealers should advise customers to consult their local planning authority before committing to a purchase. For a detailed analysis of current regulations, refer to the mobile home planning regulations guide.
Can a log cabin be classified as a mobile home?
Potentially, if the project specification and documentation satisfy the relevant Caravan Sites Act classification criteria: the unit must be capable of being transported by road (as a initial order or in two sections), stay within the prescribed maximum dimensions, and be designed or adapted for human habitation. Timber mobile homes manufactured by Eurodita can be specified around the relevant dimensional and transportability criteria while providing the aesthetic and structural qualities of traditional log construction. The timber mobile homes comparison guide examines this classification in detail.
What wall thickness is standard for mobile homes?
The standard wall thickness for timber mobile homes is 88 mm glulam (laminated timber). This specification provides the optimal balance between structural integrity, thermal performance, and weight management for road transport. Glulam construction is preferred over solid timber for mobile homes because it offers greater dimensional stability, higher load-bearing capacity per unit weight, and resistance to warping and twisting during transport and seasonal movement.
How should mobile log homes be assessed for regulated use?
Suitability depends on the selected specification, site licence, services, and approval route. Where a client requires a residential park home route, the project team must confirm the relevant standard, documentation, testing, and local requirements before final positioning or sale.
How do transport costs compare between mobile and static cabins?
Mobile home transport is generally more expensive per unit due to wide-load requirements, escort vehicles, route planning, and specialist haulage equipment. However, the total project cost may be lower because mobile homes require minimal on-site assembly, a mobile home can be sited and connected within days, whereas a static cabin requires several days to several weeks of on-site construction. Dealers should present the total installed cost (transport plus installation) rather than transport cost in isolation when advising customers.
Can dealers offer both mobile and static products from Eurodita?
Yes. Eurodita supplies both product lines under private-label arrangements, allowing dealers to offer a complete timber structure portfolio under their own brand. A single supply agreement can cover mobile homes, static log cabins, garden offices, higher-specification timber buildings, and ancillary structures. This single-source approach simplifies procurement, quality assurance, and logistics management for dealers operating across multiple market segments.
