      Luxury Granny Annexe Experts

      UK-based iHUS specialise in the design and build of luxury granny annexes. Our projects are unrivalled in quality and come with a ten year insurance-backed guarantee as standard. Every aspect of our service is tailored to you — from your free initial on-site consultation to your choice of interior and exterior finishing touches.

      In Safe Hands

      With over 30 years’ experience in construction, and an extensive portfolio of luxury granny annexes throughout the UK, you can be sure that you’re in safe hands with our team.

      Each annex that we build is covered by a ten-year build guarantee against defects in workmanship. This is insurance-backed and covers both groundworks and the annexe structure itself.

      10 Year Build Guarantee


      iHUS dealt with the complicated planning application which needed listed building consent with seamless efficiency. The timescale for completion of the new build appeared impossible to our untrained mind but not only did they keep to it, they dealt with all the many alterations both major and minor.

      Annexe Planning Permission

      A key part of our service is obtaining the necessary permissions from your Local Planning Authority (LPA) to build your luxury granny annexe, which we achieve with a with a 90% success rate.

      A householder planning application is our preferred method of obtaining permission to build. However, we can also submit a Caravan Act application, which if successful, will result in the LPA issuing a Certificate of Lawfulness (COL) — the permission we need to build.


      Spoilt For Choice

      We design and build all annexe structures at our production facility in South Yorkshire, sourcing a wide range of fixtures and fittings to suit the exacting needs of our clients.

      Our HUSCore range offers a wide choice of one and two-bedroom annexes from just £67,800. Our Contemporary annexes deliver the premium specification of a modern penthouse apartment. Plus, we build a wealth of custom annexes, if you want something truly bespoke.

      Quick & Efficient Process​

      Once we’ve received permission to build from the Local Planning Authority (LPA), we agree a start date with you. A typical annexe takes just seven weeks to build.

      This covers everything – from the on-site groundworks and delivery of materials to the final inspection and handover of keys.
