At Wyder Modular Buildings we realise just how hectic family living can be. We know that it gets even crazier when granny comes to live with you, as it’s just one more body in an already crowded home. We have a solution to that as we are expert in totally customised granny annexes. Not only are they affordable, but they are built with a truly authentic English design that assures granny’s comfort whilst giving her a little peace of mind away from all the commotion.

Bespoke Amenities

How much room does granny need? If she prefers to keep to herself much of the time we can construct a granny annexe with more than just a one-room studio design. Perhaps she needs a cloak room to store her keepsakes in and maybe she needs her own kitchenette and bathroom with a shower. We can totally customise any feature that will make her happy and feeling secure.

Interior/Exterior Customisations

Some people like the fact that the back wall has no window whilst others like to let a bit of extra light shine through. It is possible to design a window in the back and along either side wall at convenient locations. The front doors are made from a bi-fold construction which allows plenty of fresh air in on warmer days. What about a deck out front with a table and chairs or benches? Wyder Modular Buildings is proud of our talented design staff that can work any interior or exterior customisation into the layout. That’s just how good our team is!

Cost Effective and Eco-Friendly

If you are worried about cost, we would like to tell you about the cost-effective and eco-friendly features available. With the current rates for electricity, another building might just make those already high payments unmanageable. Here too, we have a solution. We can install solar panels to generate electricity using free energy from the sun – and even better, any electricity that granny doesn’t use can be fed back into the grid as an extra source of income. All of the materials we use are sustainable which means that we haven’t further harmed this lovely planet we live on. This surely will make granny happy. She’s been here a long time and remembers a much cleaner, greener earth.

Not for Granny?

Maybe your granny annexe won’t be for granny at all! Perhaps you just need an extra bedroom or someplace to house older teens as they’ve outgrown the space they’ve been sharing, two to a bedroom. Granny annexes are perfect for adding extra living space for families that have outgrown their homes and have no desire to move.

We can work into the design strategically placed electric outlets, sockets for IT connections and even build special cabinets to house computer and stereo equipment. With our talented team of experienced designers, all you have to do is tell us what you need and we can construct your modular granny annexe to your requirements.

When you’ve finally decided that you’ve had enough of all the noise, confusion and living in such tight quarters, give us a call. We are happy to meet with you for a free consultation to discuss how we can help you add that extra living space you so sorely need.
