As well as bespoke projects we offer SIPS Shell Boxes, a simple choice of four timber clad Box sizes are available flat packed, off shelf ready for delivery. Pre cut and fully designed Hemsec SIPS panels come with all the components to complete the build using an experienced trades person.

Built as well as our houses and combining aspirational design with quality, our Boxes provide stand alone contemporary structures, offering bespoke lifestyle solutions. Off the shelf designs are supplied in a shorter time, but elements of change can be discussed. supply only or supply and fix options are available subject to location.

The Boxes are pre-fabricated and designed with fire risks in mind, have a cavity and rain screen cladding along with thermally efficient double glazed windows and doors providing comfort and security.

The Boxes also come with an electrical kit & brushed chrome sockets and lighting. As a structure not exceeding 2.5 metres high, planning permission will not be required in many situations.

Our Boxes

Each structure is designed for style, functionality and longevity. The outer shells of our garden boxes are constructed using pre-fabricated Hemsec SIPS (structurally insulated panel system). First used in the 1930’s in the USA to keep the heat out they are fast becoming a popular construction method due to speed of erection on site, strength of build and the added benefits of outstanding airtightness and energy efficiency. They offer an ideal material to create your extra outdoor space, which will outperform and outlive many of the alternatives you may have considered. There are four versatile options for you to choose from:

Micro Box:
A compact space, ideal for an office/study or hobby/craft studio.

Modus Box:
Offering a well proportioned room for a multitude of uses including larger office or fitness room.

Max Box:
A practical space giving extra room for a couple of desks.

Mega Box:
The ultimate space! Escape from drum kits and band practice.
