The internal layout of your home is as individual as you are, however, there are some common themes in my 16 years of experience of remodeling homes for family living and raising two children with my wife.  Each home is different in terms of space and layout, and everyone has their own preferences and way of living.  I created the Home Consultation to provide homeowners with advice as to the best way to extend and reconfigure their homes. 
 
Front Entrance Door 
It is surprising that some homes do not have a front door or a front door which makes an impression.  Your front door should say ‘this is the entrance to our wonderful home’.  Making the front entrance door a little wider than a standard door can make a statement and also help practically with moving large items of furniture in and out.  Adding sidelights or a top light is another way of bringing natural light into the entrance hall.  Having a small canopy provides shelter to you while opening the door and also helps protect your door from the weather (a must for solid timber doors).  

Entrance Hall
Your entrance is most likely your home’s main circulation route, with your main living areas coming off of it.  If space allows, making your entrance hall as wide as possible can make a big difference to the circulation of your home, as well providing space for your child’s buggy and shopping when you come through the door.  Off of the hall and near to the entrance door, it is handy to have a cloak store for coats, shoes, cleaning equipment and other household goods where you can hide things away.  A WC off of the hall is also practical, rather than it being off of another room such as a living room or kitchen. 
 
Kitchen Dining Area
A lot of extensions I design create a combined kitchen and dining area instead of two smaller individual areas.  This provides the primary area of family interaction and social interaction, as well as an area for entertaining.  Usually, this is located to the rear of the home but depends on the layout of the existing house and personal preferences.  Usually, at the rear of the home, you can enjoy the views into your garden while cooking and eating.   The kitchen area should be practical with lots of storage space.  An island unit if space permits can be great to help achieve this.  I am a huge lover of traditional but modern shaker style kitchens, which I feel are elegant and timeless.  I absolutely love the kitchens from Humphrey Munson as below:

Pantry
Over the last year, something which I am now designing a lot of is the traditional pantry.  This is a separate small room directly off of the kitchen for storage of dry goods and bread etc. It helps keep the main kitchen area uncluttered.  If space is limited, a pantry cupboard can be incorporated within the main kitchen.

Utility/Laundry Room
If you have an open plan kitchen, a utility/laundry room is very beneficial. Getting the washing machine and tumble drier out of the Kitchen and having a dedicated area for washing, ironing, cleaning, drying and storage of laundry can be really useful.  It is recommended that the style of the kitchen cabinetry is carried through to prevent a mix of styles.

When designing a utility/laundry room, your kitchen should not be sacrificed by creating a utility room within the corner of it.  It usually makes the kitchen smaller and the utility room unpractical.  

Separate playroom
If space permits, a playroom is a great way of keeping all your children’s toys and computers in and shutting the door on,  so you can keep the rest of your living accommodation organised and tidy.

Separate office
A lot of people either work from home full-time or on a part-time basis.  Having a dedicated area for this, even if it’s just a small space can help free up other areas of your home.
