Our talented designers craft A-framed and flat roofed structures for part-time living, creating new and exciting rooms which inspire and delight from the outside in. 

Think summer house, art studio, music room, gym, library, a teenage hangout, or even a unique holiday let. It can be the perfect space to create a quiet home away from home for some much-needed breathing space - or a really fun place to entertain!

A Bonni could also be the perfect solution to part-time working - and escaping yet another dreaded kitchen table or box room workday.

For many, a stroll down the garden as a daily commute is extremely appealing – we certainly think so. And what better workspace can you ask for than one surrounded by greenery, where distractions are minimised and concentration boosted?

You might even decide your Bonni should accommodate two or more activities - with a bit of clever design you can make the room(s) multifunctional. There are endless possibilities.

As well as enhancing your lifestyle - or working environment - a Bonni provides an important opportunity to increase your property’s square footage, adding value to your home with a building that will stand the test of time. Especially if you’re using a Bonni as an office and you can convert that box room back into a bedroom.

Our outbuildings inject a new purpose to your garden, offering a combination of simplicity and charm.

As part and parcel of working with us, you will get full creative, structural and architectural support every step of the way. 

We will combine ideas and together we’ll build something beautiful that complements your garden space. 

Our process makes the experience simple and easy for you. Our Bonni outbuildings are predominantly manufactured offsite, which means that the messy bits are done on our land and not yours. 

Doing so simplifies the supply and construction chain, speeds up the time from delivery to completion and significantly reduces disruption at your home. Your Bonni can be delivered to your home for completion within an 8-week timescale.

We are passionate about making the most sustainable and eco-friendly choices where feasible.  

A Bonni can enhance the workings of your garden with options to add a green roof, guttering and water butts to collect rainfall and a foundation solution which allows rain to run back into the soil. 

But we can do much better than that. Our outbuildings allow you to choose your preferred method of energy use (solar, wind, biomass), offering off-grid and on-grid set-ups and an ethos of maximum energy efficiency. We can install a combination of technologies such as solar, battery and generators to supply electricity completely off-grid.

This is determined by the site, of course.

Whatever you choose, we can create a truly individual Bonni that you will one day wonder how you ever managed without!

Bonni Outbuildings was founded by Denny in 2020 when his desire to escape a high-pressure, office-based career was accelerated by the loss of his IT business during the pandemic. 

With time on his hands, he was able to realise his dream and pursue his true love of rural architecture and outdoor living. Denny’s ‘passion project’ follows a lifelong love of wood having grown up with a family timber business – just a few miles away from Bonni HQ.

Denny now creates stunning garden building designs that blend with nature. He is proud that each Bonni is timeless, architecturally designed and beautifully crafted.

He is passionate about sustainability, which lies at the heart of the brand.
