Pontoon Houseboat Hulls

Designed specifically to offer a versatile, budget and maintenance free alternative to both traditional floating home hulls and inferior market options, our pontoon floats are able to be arranged in any formation required; to suit beam, length and even extreme loading scenarios. Contact us for advice on choosing the right framing for your application; commonly timber, mild steel or even 316 stainless steel for the most agressive environments. With the purchase of floats we provide acces to a library of technical drawings, fabrication guides and free consulations, making DIY floating homes truly acessible even to home builders. 

Examples of structures used (or proposed) thus far on top of an assembled pontoon 'raft'  include; static caravans, shipping containers, glamping / Airbnb pods, log cabins, steel framed superstructures, timber framed homes, industrial workstations, horseboxes, ramped vehicle decks, launching yacht trailers, wet docks, covered boat storage, balcony decks, butties, tenders, painting platforms, lake houses, mooring pontoons, dragon boat boarding docks, powered party rafts, etc, etc! 

Benefits of using our float units for your floating home include;


  • The ‘hull’ of a houseboat using the system wouldn't require blacking or any standard, expensive. out-of-the-water maintenance

  • Each float effectively works as a floatation ‘cell’. This adds a huge amount to the safety of a vessel. Plus in the unlikely case of puncture, they are replaceable even after being framed

  • Each float can comfortably account for 500kg of required vessel buoyancy, whilee still leaving a healthy 'freeboard' of float above the waterline

  • The floats provide a massive insulatory advantage compared to the thermal bridging issues associated with traditional displacement steel hulls

  • Framed in formations such as trimaran or quadrimaran, gaps between the linear runs of floats mean that a pontoon hulled vessel has no contained bilges like a one-piece craft. This hugely helps solve condensation problems and even protects aginst water leak based sinking dangers, and puddling vented LPG.

Case Study: The Charnwood Ark

Our first, prototype, proof of concept floating home utilised 17 floatation cells, framed with home-fabricated mild steel. Key to the concept was that the 'raft hull' could be built and launched in modular sections before adding roof frames (again mild steel), cladding, roofing, glazing and lining. This enabled the full boat to be built from a riverside mooring without the requirement for unit hire, heavy machinery or slipway fees.

Key Info:

  • 17.15m x 3.84m / 56' x 12'7"

  • Trimaran array of floats for the first 40', changing to catamaran for the final 24' to enable a subfloor 'boat garage' housing canoes and a motor launch

  • Mild steel framing, mig welded and coated in two-pack marine epoxy paint

  • No module exceeding a 'two-man-lift'

  • Clad with shiplap jointed, roofing-torch scorched then oiled, 36mm thick scaffold boards and galvanised steel sheet

  • Single piece EPDM rubber roof

  • Celotex 25mm insulated internally throughout

  • Pump out toilet utilising the central float on the bow deck as a black water tank

  • Solid fuel stove and Worcester Bosch Air-to-Air heat pump / air conditioning

  • Instant hot water via LPG flash water heater, housed outside in a bow locker

  • LPG range cooker, fed from a separate 19kg LPG bottle also sited in a sealed bow locker

  • Moored on a river experiencing heavy flooding, two welded on bull horn cleats rope to rings and vertical poles.
