Custom Built Annexe Design

Have it Your Way, have a custom built annexe.

Perhaps you have a specific vision in mind for your custom built annexe, or you need to abide by specific limitations, such as those found in conservation areas? Then our custom design and build service may be the right option for you.



This 1 bedroom bespoke Annexe is home to a family from South Africa, their Annexe has enabled them to live in an area that they love close to their beloved family and grandchildren. Find out how the family are getting on, by watching their interview and Annexe walk through video…


This idyllic annexe is home to Theresa and Austin situated at the bottom of their daughter and son in law’s garden. Having always lived very closely to one another, the family were convinced this way of life wasn’t going to end anytime soon, & their wonderful annexe has made this a reality!

Perfect for all Grand Design Enthusiasts

iHus custom-built annexes are like self-building on a smaller scale, allowing you to add your own design input into both the interior and exterior elements of your annexe from a wide choice of options that are available. We always say to our customers that one of our customers lives in the annexe, but the other one has to look at it.

Custom annexes are perfect for conservation areas or Grand Designs enthusiasts who have always wanted to design and build something themselves but didn’t know-how.

If you haven’t thought about it, you should because there are immense benefits. It’s worked tremendously well for me in a way that I didn’t expect it to be as good as it is.

Annexes in Conservation Areas

Living in our green and pleasant land allows us to enjoy all the benefits of our heritage but also presents us with guidelines and restrictions to work within if you are thinking about erecting a custom built annexe in a conservation area or area of outstanding natural beauty.

With custom exterior finishes that include Green Oak cladding, Rosemary Roof tiles, cottage style doors, timber stained windows and more, all you have to focus on is what colours from Farrow and Ball would suit each room. As we have successfully custom built annexes in strict conservation areas it’s certainly worth contacting us to see how we can help.

Coping with Quirky Garden Plots

iHus custom-built annexes are a perfect choice if you have a quirky garden or plot that suits a specific layout for your annexe to maximise where it should be ideally situated. With added custom annexe choices of skylight roof windows, extra sets of French doors, the position of the front door and the best place to add that all-important sun deck to factor in, our custom-built annexes are flexible enough to cope.

All our custom annexes are drawn up specifically for you by our technical teams and will be built to exceed Building Regulations giving you peace of mind that they have been built to last for a lifetime of daily use.

You’ve got to rate it 10/10. Just take the plunge and go for it. For me it’s been a dream come true.

Custom Kitchens & Bathrooms

Just like our own homes, annexe kitchens and bathrooms are important features of every granny annexe we build. One of the best and most popular aspects of building an annexe for a family member is the ability to adapt it to match the requirements of its new owner.

iHus custom-built annexes not only offer you a greater choice of layout, styles and design elements for your annexe, but if the final look of your annexe simply wouldn’t be complete with a kitchen island, custom annexe design options are for you.

On a more practical side, bathroom adaptations are something we specialise in. So if you have safety for an elderly relative uppermost in your mind, we have you covered.

Free On-Site or Virtual Consultation

Every custom annexe we build starts with you and what you have in mind. We’ll advise you on every aspect of your dream annexe and advise you on the best way to go about obtaining planning permission approval when you book a Free On-Site Consultation with one of our experts. Following government advice about social distancing, we’re introducing a remote consultation service to meet the current high demand for our annexes. This free service will clarify the feasibility and specific costs of building an iHus annexe in your garden — all from a phone or video call.

If you have a particular project in mind that you want to discuss with people who have been building annexes from Armstrong to Cornwall and everywhere in between, then why not see if we can turn your ideas into a dream annexe that you and your family can enjoy for years to come?
