Technical intelligence and expertise for UK annexe projects
ABOUT ANX
DELIVERING SPECIALIST TECHNICAL INTELLIGENCE AND EXPERTISE FOR ANNEXE DESIGNS
Headquartered in London, ANX has been serving clients throughout the UK for more than 20 years. We work predominantly with annexe and outbuilding designers and suppliers, property developers, and architecture practices.
We’ve worked on thousands of garden design projects and dealt with over a hundred different local authorities. We know how the system works, what to expect, and how to deal with the unexpected. We’ve probably already come up against the problem before, and even if we haven’t, we’ll know the quickest, easiest, and most cost-effective way round it.
WHAT WE’VE LEARNT FROM EXPERIENCE ABOUT GARDEN DESIGN PROJECTS:
• No two projects are the same.
• No two local authorities are the same.
• No two sites are the same.
• No two suppliers need the same amount of support.
We share our experience and expertise to ensure you don’t make costly mistakes.
BESPOKE SERVICES THAT COVER ONLY WHAT YOU NEED
We know you may only need one standalone service, whether that’s related to planning, building control regulations, or help with the technical and engineering aspects of your project. You might need a construction team, project management, or aftercare.
Alternatively, you might want end-to-end support from the moment you have your design to maintenance of the garden room our construction team have completed.
That’s why, unlike many of our competitors, our pricing is transparent and you can use as many or as few of our services as you require.
EXPERIENCE, EXPERTISE, AND INNOVATION
We pride ourselves on our training, technical intelligence, and carefully developed and maintained relationships with planning officers, buildings inspectors, and other industry professionals.
We take an innovative approach to technology and use that and our experience to solve problems more creatively. We are used to dealing with all stages of large, complex garden-design projects as well as smaller, more straightforward ones. If your annexe or garden room is large enough to require planning permission, we can help.
YOUR QUALIFIED, CERTIFIED, ACCREDITED, AND INSURED CONSULTANTS
Our fully professional, specialist team has all the accreditations and qualifications required to work in the industry. We leave nothing to chance and carry out due diligence before making any assessments or recommendations. ANX is SSIP-registered (Safety Schemes in Procurement.
We can act as your planning consultant, buildings control partner, health and safety adviser, and supplier. We also advise on the certification schemes and how and when they can be used, such as BSI and BREEAM.
We do not offer any services we are not qualified to provide.
SUSTAINABLE AND ECO-FRIENDLY SOLUTIONS
We have extensive experience with environmental standards and policies, including Passivhaus.
This enables us to advise on sustainable and eco-friendly solutions and standards too.
ANX IS COMMITTED TO QUALITY SERVICE
No matter the level of service you require, or the stage your project is at, we are committed to the delivering to the highest standards. Whether it’s project delivery, craftmanship, or safety, our team doesn’t settle for second rate. We do what we’re best at – so you can focus on what you’re best at.
