At Green Retreats, we know the little details make a big difference. Our B-Range is the perfect starting point as a simple, cost-effective ‘base’ model. The B-Range has fewer features included as standard than our fully inclusive garden room ranges, keeping the price low but the opportunities high! Choose from a range of ‘add-on’ packs, or get crafty with DIY or get quotes from your local tradespeople.

Our packs give you the choice of how hands-on you’d like to be with your B-Range project. Add them on if you’d like us to take care of everything, or leave them off if you’d prefer a more DIY approach. It’s all about making the build work your way and saving costs.
If these pack options are included in your B-Range project, they overall package of your project would match what we offer with our G-Range.
