Types of home extension

  • Over-structure extension

Single storey extension

Extending your home on one level, usually to the rear or side of the property ( sometimes both see wraparound extensions ).
A popular choice for kitchen extensions, often creating an open plan kitchen / diner, opening up your kitchen and improving your connection to the outdoor space at the rear of the property.

  • Kitchen / diner
  • Dining room
  • Additional bedroom
  • Home office
  • Playroom
  • Utility room

Double storey extension

Extend outwards and upwards ! Double multi-storey extensions are most commonly utilised to provide an extra bedroom or bathroom above a kitchen extension.

Side return extension

Also known as “side infills”. Extending outwards to include the full width of your property. Contructing a side return extension, ie. utilising the dead space at the side of your home, possibly an alleyway, path, patio could result in a considerably bigger kitchen, especially if there is available space on both sides of the property.

Rear extension

Extending your home outwards at the back of the property, into an existing garden, courtyard or patio space with a seemless transistion between indoor and outdoor spaces with the use of bifold doors.

Wrap around extension

A wrap around extension most commonly combines a side return extention with a rear extension, essentially forming an ‘L-shaped’ footprint.
However there are many other possibilities and permutations. If space allows, you could extend out the front and side, you could also combine multiple wraparound extensions, thus completely enclosing the original property.

Extending your property in this way is an opprtunity to really maximise the avalaibe light and space. It can result in significantly altered internal spaces, the creation of substantial open plan layouts, extended kitchen area, additional dining room and extra bedrooms.

Over-structure extensions

Over-structure extensions are built over the top of an existing structure, most commonly a garage, but sometimes a Bungalow or other single storey dwelling.

This type of extension will give you the benefit of adding an extra bathroom, home office or bedroom, whilst preserving your precious your garden space.

Other options for extending your Northamptonshire home

Cellar conversion

Cellars are a pretty common feature in Northamptonshire, particularly in Victorian properties in the larger towns – Northampton, Wellingborough, Kettering and Rushden. Originally, they would have been used for storage – a cool space for keeping food, before the invention of domestic refrigeration. Many were used as workshops, especially for those who worked in the Boot & Shoe industry.

Dormer extension

A dormer extension could be the answer iff you have an unused space in your attic. A dormer consists of a roofed structure, often containing a window, that projects vertically beyond the plane of a pitched roof. Percfect for that extra bedroom, home office or child’s playroom.


Though not often though of as an extension per se, a porch can be exacatly that !
Defined as “a structure that is outside the main walls of a building or house” – A porch is essentially a small extension at the front, rear or side of the house. Sealed from the weather, porches can double up as a bootroom / cloakroom and even have lighting and electrical sockets.

Accessible Homes

You maybe living in an inaccessible home with a life-changing injury or disability. It can therefore be a struggle to do simple tasks that others take for granted. Problem areas may include :-

  • Steps up to the entrance of the property
  • No bathroom facilities on the ground floor
  • The internal doors are not wide enough
  • Inaccessible shower

A ground floor single story extension can accomodate a new accessible bathroom / wetroom and provide level access to exterior of the property.


  • Size of the extension
  • How will the roof work with the existing building?
  • Impact upon neighbours
  • Location of drains and other services
  • Additional excavations / foundations
  • Can my existing structure support another storey without the need for reinforcement ?
  • Planning permission

The experienced building team at Liberty design and build can help with all these queries. Call us on 01933 716018 or contact us via the contact form on this page, to discuss your project.
