Rear Extension Ideas

So you’ve got the budget and some ideas but can’t quite decide on the layout for your rear extension. When you have your initial consultation with your chosen Architect/Architectural Technologist they will look at different options available to your project taking into account regulations, lifestyle, your personal design, budgets and material options. To help you choose the right layout for you we have listed a few ideas of what you could achieve. For more information, make sure that you call Detailed Planning’s planning consultant team.

It can be about creating seamless transitions from the new space to the existing, both inside and outside of your property or a completely separate space.  Rear extensions are the most popular types of residential extensions with wrap around, double or single storey. 


Need an Extra Bedroom?

If you have an ever growing family and the thought of the now toddlers sharing a room when they are teenagers feels you with dread, this could be a fantastic option. The norm for an extra bedroom would be to build a double storey but if your budget doesn’t allow for this then don’t discount a downstairs bedroom. If you need the extra bedroom then the cost of this compared to moving could save a lot of money in the long term.

Utility Room?

Thinking of building an open plan kitchen towards the rear garden? Look into an option of adding a utility room into the design. It will save you having to shout over that noisy washing machine and tripping up those clothes dryer in the winter.

Additional Bathroom/Shower/Toilet?

It’s said bathrooms can add 4-5% on to the value of your home. Just think of what an extra toilet, bathroom or shower room could do to your day to day living in a busy family home (no more queues for the bathroom). The long-term benefits are great also for people thinking of their forever homes, as a downstairs bathroom/loo are a great help with young children and the elderly.


Just think when the kids go to bed and you just want to sit on the sofa ready for an evening of Netflix, but now you have to spend most of your evening tidying toys away that you know will be straight back out in the morning. Imagine an evening where you don’t have to do this and you just close a door! Amazing right? You have your evenings back to enjoy. Now we’re not saying spend 30-50k on extending just for a playroom. Being clever with your layout by extending other rooms such as the kitchen could allow for you to make some internal changes that will mean you can change the use/split with other rooms to create a playroom. In the long term this room could be used as an office, extra/guest bedroom, gym, etc!

Snug Space?

A snug is a small and private space that’s designed to offer peace and relaxation. Just think of those cosy nights on the sofa in front of a good box set. If you have a large open plan living space then adding on a snug is a great place to hide away at the end of a long day.

Gym? – Saving those monthly membership

Adapting a garage is sometimes the most obvious way to create a gym at home but not everyone will have this luxury. A gym won’t add value to your property but if you choose to sell then the gym can be marketed as a spare bedroom etc. If it will suit your lifestyle and you have the space we say go for it!



This is the most popular option for a rear extension and there is good reason why… extra space, open plan living, adding value to your home, and bringing people together in a central space. There are so many design/layout options for open plan/extended kitchens.

Living Room?

If you have a layout where your kitchen is in the front of your property increasing your living room or adding a new space on the back without going to an open plan design is a great option to allow for more space for a growing family.


Office – Where you will create your multi million pound business!

Much like a playroom this is a luxury to be able to extend only for this room so we say look at the same principles as the playroom and go by that. Top Tip for offices – if space and layout allow, place your desk facing towards a window to allow you to look out into the garden when working, this may seem counterproductive but just the little break looking out the window on to a lovely view may help you be more productive.
