The Power® Apex Shed comes with heavy duty framing, non-tear roofing felt, extra high wall height, and a 10-year guarantee as standard, however the most appealing feature of this shed is the vast range of door and window layouts available… allowing you to create your perfect shed.

This shed is supplied pre-treated with a quality, brown (golden oak), non-toxic preservative base coat. Each panel is treated inside and out (including end grain, tongues, grooves and cut-outs. This is a long-lasting preservative, allowing you to use the shed straight away. There is no need to paint for the first year, but you can change the colour or over-paint at any time if you prefer.

The doors on this shed are great… they are fitted with heavy framing complete with diagonal bracing stop sagging, they can be hinged on the left or right side, they are fitted internally with a rim-lock c/w mortice key for convenience, and have an easy grab handle.

About Power Sheds


Innovative Design
Expected life expectancy of over 25 years
An unprecedent leap in the garden shed industry. Meet the first modular garden building to combine cutting edge design with the legendary simplicity of a garden shed.

We have created the world’s most adaptable shed – you can put the doors and windows on any side, which you choose as you assemble the building. No other shed gives you as many options.

Equality and diversity in manufacturing

We are committed to promoting equality of opportunity and have developed a number of key policies and procedures in important areas in our organisation. However, having policies is not enough. We ensure all of our polices regarding equal opportunity are implemented and we continually take practical steps to fulfil the commitments expressed in them.

Various sources offer conflicting statistics, but one thing is starkly apparent – UK manufacturing has a large gender and diversity disparity, and progress appears to be moving at a glacial pace. With the country facing a seemingly perpetual skills shortage, industry’s traditional approach towards recruitment and engagement needs to be left in the past, where it belongs. We aim to be a part of this movement.

Responsible & Sustainable Purchasing
We have a passion for high quality slow grown timber with traceable and transparent sourcing:

We have high quality standards from forest to sawmill to our factory;
We have a rigorous sourcing policy across our entire supply base, and our ambition is to make sure our products are manufactured with certified timber under a sustainable forest management scheme;
We are currently in the process of joining the FSC to certify our existing sustainability policy of purchasing timber only from managed forests.

Best of British Quality
Manufactured in Yorkshire
Britain is the birthplace of the industrial revolution – and remains a leading manufacturing nation today, as well as a world leader in hi-tech sectors. There are 2.6 million people directly employed in manufacturing in the UK. We ensure all of our manufacturing is completed in the UK and continue to develop all of our manufacturing staff with our in house training academy.
