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 (permanent timber buildings). While both are manufactured from timber and both serve residential and commercial purposes, 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). Single-unit structures share the same length and width limits. These dimensions are critical for dealers to communicate accurately, as exceeding them reclassifies the structure as a building rather than a caravan, triggering full planning permission and building regulations requirements.
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 single unit 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 any size, any configuration, and any specification that complies with local building regulations.
In the UK, static log cabins typically require full planning permission under the Town and Country Planning Act 1990. They must comply with Building Regulations (Part A through Part P) if intended for habitation, including structural integrity, fire safety, energy efficiency, and accessibility standards. 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 220 mm or more for fully insulated residential dwellings. 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 | Often not required on licensed caravan sites; Permitted Development may apply for agricultural/forestry use | Full planning permission typically required; Permitted Development rights may apply for ancillary garden buildings under 15 m³ |
| Building Regulations | Exempt if classified as a caravan under the 1968 Act; must meet BS 3632 for residential park homes | Full compliance required for habitable structures; exempt for small ancillary buildings (under 15 m³, no sleeping accommodation) |
| 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; no permanent foundations required | Concrete slab or strip foundations; structural engineer specification recommended |
| Site Requirements | Licensed caravan site, agricultural holding, or site with specific mobile home permission | Any site with appropriate planning permission; residential, commercial, or agricultural land |
| VAT Treatment (UK) | Zero-rated if qualifying as a residential caravan (VAT Notice 701/20) | 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 | Standard buildings insurance; may require specialist timber structure cover |
| 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 Nordic 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 permanent habitation). 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 (tolerance ±±2 mm), 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 require compliance with the park licensing framework and often specify particular colour schemes, layouts, and specification levels to match their brand positioning.
Residential park home sites serve occupants seeking permanent or semi-permanent accommodation. These units are sold to individual occupants under the Mobile Homes Act 1983 (as amended). Higher specification is expected, including full thermal insulation, central heating systems, and residential-grade kitchens and bathrooms. This segment commands higher unit values and longer sales cycles.
Agricultural and rural accommodation uses mobile homes to provide housing for farm workers, estate staff, and rural businesses where conventional planning permission for a new dwelling would be refused. 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.
Residential dwellings represent the highest-value segment. Log homes and glulam houses built to building regulations serve as primary residences, with floor areas from 60 m³ to over 200 m³. This segment requires dealers to provide comprehensive technical support including architectural drawings, structural calculations, and building regulations guidance.
Holiday letting properties combine the appeal of timber construction with commercial income generation. Self-catering holiday cabins in rural and coastal locations command premium rental rates compared to conventional accommodation. Planning permission for tourism use is often more readily granted than for residential.
Ancillary accommodation (granny annexes) provides additional living space within an existing residential curtilage. This segment benefits from simplified planning routes in many local authority areas and serves the growing demand for multi-generational living arrangements.
Energy Performance and Habitation Standards
Energy performance is a decisive factor for structures intended for year-round habitation. The thermal characteristics of mobile homes and static cabins differ based on construction method, wall thickness, and insulation approach.
Mobile home insulation must balance thermal performance against weight and dimensional constraints. The standard 88 mm glulam wall provides a base U-value of approximately 0.65 W/m³K. Additional insulation is applied within the wall cavity and roof void to achieve overall U-values that meet BS 3632:2015 (the residential park home standard). BS 3632 specifies minimum thermal performance requirements for floor, wall, and roof elements, as well as ventilation and condensation management. Modern timber mobile homes manufactured to this standard provide comfortable year-round habitation with acceptable energy performance.
Static cabin insulation options span a wider range. A basic 44 mm solid log wall (U-value approximately 1.4 W/m³K) is suitable only for seasonal use. A 70 mm wall improves to approximately 0.95 W/m³K. For year-round habitation meeting current Building Regulations Part L (England and Wales), the twin-skin construction method is the preferred solution: two interlocking log walls separated by an insulation-filled cavity achieving U-values of 0.15–0.20 W/m³K, comparable to modern conventional construction.
Both product types are compatible with standard heating systems including gas central heating, electric heating, air-source heat pumps, and underfloor heating. For structures intended as primary residences, dealers should advise customers that static twin-skin cabins will achieve superior long-term energy performance, while mobile homes manufactured to BS 3632 provide adequate performance within the constraints of the caravan classification.
The emerging emphasis on Energy Performance Certificates (EPCs) and net-zero targets across Europe makes energy performance an increasingly important element of the sales conversation. Dealers who can articulate the thermal performance characteristics of each product type — supported by calculated U-values and EPC predictions — will close more effectively than those offering generic specification sheets.
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 large residential dwellings 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 (residential dwellings requiring planning permission and building regulations approval). 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. Single-unit structures share the same length and width limits. Any structure exceeding these dimensions is classified as a building rather than a caravan and requires full planning permission and building regulations compliance.
Do mobile homes need planning permission?
Mobile homes sited on licensed caravan sites or residential park home sites generally do not require individual planning permission, as the site licence covers the use. 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 workers may benefit from specific exemptions. 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?
Yes, provided the log cabin is designed and engineered to meet the Caravan Sites Act requirements: it must be capable of being transported by road (as a single unit or in two sections), it must not exceed the prescribed maximum dimensions, and it must be designed for human habitation. Timber mobile homes manufactured by Eurodita are specifically engineered to satisfy these legal requirements 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.
Are mobile log homes suitable for permanent living?
Yes. Timber mobile homes manufactured to BS 3632:2015 standard are designed for permanent residential occupation. The standard specifies minimum requirements for thermal insulation, ventilation, structural integrity, and fire resistance that ensure year-round comfort and safety. Many thousands of people across the UK live permanently in residential park homes. The key requirement is siting on an appropriately licensed residential park home site with the necessary infrastructure connections.
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 covers mobile homes, static log cabins, garden offices, residential buildings, and ancillary structures. This single-source approach simplifies procurement, quality assurance, and logistics management for dealers operating across multiple market segments.
