Architectural flagship · 34.8m²
The A-01 is not a scaled-up M-series. It is a different kind of building, designed from the outset as an architectural statement, with a spec to match. The frame is heavier, the glazing runs floor to ceiling on the primary facade, and the interior finishes are specified at a level that most residential extensions don't reach.
At 34.8m² it is similar in floor area to the L-04, but it sits differently in the landscape. Lower, wider, and more considered in how it meets the ground. It reads as a proper piece of architecture.
We build one or two A-01s per year. It is not a product so much as a collaboration. The right starting point is a conversation.
Planning permission is required in every case. We can recommend experienced local architects or work alongside your architect of choice.
The M-02 arrives as a finished shell with all electrics and delivery included. From there, you choose which facilities you'd like to include. The list below shows what's available: take all of them, or any combination that suits how you plan to use the space.
Shower, basin and WC. Hot water and full plumbing.
Double bed with integrated drawer storage beneath.
Hob, sink, worktop and under-counter fridge.
Seating area with room to configure to your use.
Wood burning stove, flue and first load of logs.
Each facility is priced individually and confirmed during your build conversation. Mix and match to create the environment that suits your brief.
We offer a curated set of exterior and interior material choices to guide the design. These are the options we know perform well and age beautifully. If you have something else in mind, we can work with it: that becomes a bespoke design conversation.
Western red cedar is our default and most popular choice. Naturally resistant to rot and insects, it requires no treatment. Left untreated it silvers gradually to a soft grey. Warm, light-weight, and dimensionally stable even in the Sussex climate.
Weathering steel that forms a stable, rust-like patina as a protective surface layer, eliminating the need for painting or further treatment. It gives the M-02 a distinctly industrial and architectural character. Extremely durable, with a lifespan measured in decades. Note: initial weathering can run slightly; discuss placement near light-coloured surfaces.
Scots pine is a more affordable cladding option with a lighter, more traditional timber appearance. It benefits from a treatment coat every five to seven years and weathers to a warm golden tone if left. Works well where a softer, more rustic aesthetic is wanted.
An ancient Japanese technique of charring timber to carbonise the surface. The result is dramatically beautiful: a deep black finish with visible wood grain. The charred layer is naturally resistant to fire, rot, UV and insects, making it one of the most durable cladding finishes available. We apply this to cedar or pine.
Structural birch ply is our most-used interior finish and what you see in our cabin stays. The face veneer is pale and smooth with a fine, consistent grain. It reads as warm and resolved without being showy, and it handles knocks and life far better than painted plasterboard. Used across walls, ceiling, and floor.
A broader category covering species like poplar, okume, and hardwood-faced ply. Slightly different aesthetic to birch: more visible knots and grain variation depending on species. A good option where texture and character are wanted over the cleaner birch face.
Tongue-and-groove Radiata pine boards give a classic cabin interior: knotty, textured, and warm. It reads very differently from ply, giving a more traditional Scandinavian or alpine feel. Can be left natural, oiled, or painted. Works especially well on ceilings.
Sourced from demolished structures, old school gyms, industrial buildings and barn conversions. Every board has a history. The character varies depending on source, but it is always warm, always rich, and impossible to replicate with new materials. Our cabin stays use reclaimed timber throughout. Uses reclaimed material reduces embodied carbon significantly.
Our curated list covers the materials we know work well and can specify confidently. If you have a particular material in mind that isn't listed, that's not a problem: it simply becomes a bespoke design conversation at the start of the project. We'll assess it for performance, longevity, and compatibility with the M-02 structure and advise accordingly.
