Power & data pack

Connection via Bluetooth Wise Box to control your Arc remotely.


The Arc’s integrated lighting is specially designed to help you to work, play or relax.

LED downlighters provides a gentle ambiant light wash throughout the interior.

The external canopy space is also gently lit with Nordlux Up/Down lights.

Flush threshold Aluminium Doors

The Arc is designed to be enjoyed as an open room. Thin framed doors maximise the amount of glass possible and the flush threshold allows the balcony and interior to become one space.

With high levels of UV protection and thin double glazing, not only does the Arc open up when you want, but protects you from the sun and cold.

Floor finish

Each Arc needs to be warm inside, safe outside in the wet and enable the owner to feel that it is all a single space whether the doors are open or closed.

The optional Ceramic floor tiles from Novabell enable us to offer underfloor heating inside and slip resistance outside, minimising maintenance and wear.

Sustainably sourced Cladding

The Arc deserves to be dressed in the finest materials and we select the finest sustainably sourced Eucalyptus, Red Cedar and Siberian Larch cladding for each one, supplied by specialist timber merchants Millworks.

The cladding can be treated to protect againsat UV or painted in any colour you like.

All-round Insulation

Our Arcs have a combined insulation system, with all-round insulation (roof, walls and floor) providing the highest level of insulation, maintaining the right temperature year round with the minimum of energy consumption.

The optional Sedum Grass Roof insulates and protects in any climate, providing year round flora and fauna, it is butterfly and bee friendly.

Concealed Free Rain Drainage

The Arc has nothing to clutter its external shape, with a patented concealed guttering leading into a Free Rain water drainage system.

All rain and snow is drained and distributed efficiently, and available for recycling if required.

Paint & Decorating

Each Arc is finished internally to a very high quality, with your choice of Little Greene Company paint colours.

ARC BENEFITS Beautifully Simple

Multiple Uses

The Arc is designed for multiple uses, from an inspiring home office to a relaxing reading room, a cool den for teenagers, a serene yoga studio, a dynamic gym, a unique guest bedroom, your imagination is the only limitation.

As a fully insulated, ventilated, heated, well lit, powered and secure building, it can be anything you need your Arc to be.


The Arc, its materials, footprint and height, have all been designed for a quick build; our signature build, Arc 1 needs no planning permission unless local or conservation limitations apply.

All other Arcs will need planning permission.

One our Directors has over a decade of professional experience as a Surrey Planning Authority Officer and will be able to guide you or answer any questions you have.

Site Prep and Groundwork

Our recommended foundation for the Arc is to use screw jacks which are the most environmentally sensitive solution, however, should you prefer to have a concrete base prepared the Arc can be positioned on that.

Your Arc will hover over the ground, safe from damp, clearing drainage and tree roots and can manage a slope of up to 5 degrees as standard.

Our preferred contractors will be able to assess your soil conditions and will recommend and install the correct solution, if required.

Time to build

Assembly of an Arc is a specialist procedure and requires a team of up to three skilled tradesmen.

Assembly of our Arc 1 (4x4m) will take two weeks.

For all other Arcs, we will let you know a detailed programme of delivery, design around you and your circumstances.

Our highly trained carpenters, builders and decorators are self sufficient and will not require access to your house, power or utilities.

We believe that a clean building site is an indication of a good site and it will be kept clear and safe for you throughout.

sustainably sourced materials

When designing the Arc, we wanted to create a structure that is not only beautiful and functional, but also takes care of the world in which it sits.

We choose high quality, sustainably sourced wood and build with recycled and sustainable materials where possible.
