Your Garden Studio is a versatile, high quality asset to your home. Whatever the need for more space, (garden lodge, games room, home extension, guest room, personal gym), your Studioni room affords genuine year-round comfort and is built to last.  We have not found any other builder who guarantee their work for 10 years – insurance backed and deposit protected.  That’s what we give.  The very best warranty available.

Our in-house designer has been creating garden buildings for 8 years so we can create a one-off design which perfectly complements the site and purpose you have in mind.  Alternatively, you can choose from our most popular designs through our Products tab or design your own garden room. 

Studioni design and build eco-responsible garden lodges, garden studios and garden offices, sunrooms and home extensions for British and Irish customers.  A top quality, timber frame, room in the garden is a real alternative to moving house and a secure investment in uncertain times. Studioni have carefully researched their building materials so the end product looks beautiful as well as being energy efficient and eco-friendly.

During your search for a garden room, have a look at our blog (access it through the blog tab at the top of our main site).  We publish well written articles on aspects of our industry with the aim of helping customers understand the jargon, spot the false promises and get the very best value for their money possible.  Some clients may need a single skinned timber shed – clearly, this is not what we do.  Our prices start at £9997 for our small office but we can design less expensive rooms which are also well insulated and suitable for daily use, all year round.  Let us know what you need, we have the skills to adapt and reform any design to meet your requirements for extra habitable space.
