With everything from mass-produced kit buildings to bespoke bobby dazzlers out there, the crowded garden room market is difficult to navigate. What are we offering that sets us apart from the others?

Every Blackstone Garden Room project is entirely unique. We start with a blank canvas and use our Consultations to determine exactly what you need and want from your building.

Our expert Sales Team make sure that your final design fits your space, your budget and your intended purpose, so that your completed building is exactly what you need. Nothing more, nothing less.

Our 35+ years in the timber building business demonstrate our commitment to getting things right, even when it takes extra time or effort. And our 30-year guarantee is proof of our confidence in our products and our commitment to our customers.

Buying a Blackstone Garden Room isn’t just about the top-quality building. It’s a complete package of customisation, choice, collaboration, expert attention and a project-management service that ensures everything runs smoothly.

Composite cladding can be a cheaper alternative to timber, but can also be a more expensive alternative to timber. There are just as many different composite products available as there are timber varieties, and these vary in price, quality and suitability.

Unfortunately it’s extremely difficult to assess the quality and longevity of composite products beyond finding a company whose word you trust. That’s why we use timber – its variety, origin and hand-selected quality are proof of its performance.

This is worth being upfront about. The price list reflects the building itself – but your full project cost also includes groundworks and electrics and plumbing (if you opt for this), which aren’t included in that figure. We’ll walk you through a full cost breakdown at Consultation so there are no surprises later.

We coordinate and project manage groundworks and electrics as part of the overall process — introducing you to our accredited trades (including our sister company, Solid Ground, for groundworks) — but these are priced separately from the building itself. This is worth checking when comparing quotes, as some companies bundle these costs into their headline price and some don’t.

There’s no automatic requirement for planning permission for a Blackstone Garden Room – many are built under permitted development rules. That said, position, height, size and your specific property can all affect this, so we’ll confirm your situation at Consultation, and we offer a planning application service if it’s needed.

Our Radiata Garden Room specification is available for buildings up to 12m², while Blackstone Garden Rooms cover buildings over 12m². Blackstone Garden Rooms are also fully bespoke builds rather than standard designs. If you’re unsure which fits your space and budget, that’s exactly what a Consultation is for.

Yes – as long as you have heating and lighting! Our Building Control-compliant specification means that every Blackstone Garden Room is legally suitable for human habitation, whatever the weather.

Whether you need business premises or holiday homes or spare bedrooms for teenagers who won’t stop growing, a Blackstone Garden Room is engineered for year-round comfort.

There are lots of variables to consider when mapping out your Blackstone Garden Room project, including design changes, our lead times, and whether or not planning permission or building warrants are needed.

The process runs through Consultation, design and quotation, groundworks, manufacture, and a multi-stage on-site build (structure, insulation and lining, electrics first and second fix, final finish).

We’ll give you a realistic timeline specific to your project at Consultation and keep you updated throughout each stage.
