Does the property feel more and more cramped? Is the household getting bigger and will be soon in dire need of more space? Or perhaps, thinking of getting that office or playroom room you always wanted? There are thousands of dreams and reasons as to why build up an extension, too many to list. But it is clear, the we all want to make the best of our living space. And an extension may be just what you need.
Our team, at AFL Construction, have had the pleasure to make those dreams come true. Through our experience in building extensions for our clients, we have picked up a few things along the way that might help you into finding your reason.
One of the first question that always comes to mind is: How much would it cost to build an extension?
Do keep in mind that every property is unique, therefore it would be complicated to give a figure that would cover every type of residence. But after years of estimating extension projects, we can say that a typical terraced extension shell in London would cost £35k upwards (subject to VAT).
For this brand new home space, the potential additions (assuming basic to mid range) and inclusive of building works and supplies would be:
Bi-fold doors £2k to £5k
Kitchen £3k to £15k
Bathroom £3k to £7k
Toilet or Utility room £1.5k to £3k
Flooring and skirting £3-5k
Lighting and electrics £1-7k
- Alterations to the existing property are subject to scope and size. An average of £700 to £1500 per m2
- Landscape and external works are also subject to scope.
The figures above would cover the building cost of the project. However before building works start there are some pre contruction costs that you may incur:
- Planning permission application,
- Party wall agreement
- Structural engineer fees
- Architect fees to for the design consultations before the works. You might also have the Architect to advice during the build.
- Planning and construction drawings, and structural design. Which would altogether come to around £1,5 to £5k.
All in all, these figures are an approximate and we would strongly advice you to get a specific estimate of your project.
On another note, we would be happy to welcome you to work these numbers with our team at AFL Construction.
In order for us to help provide an accurate quote, we would need the drawings, scope of works and the schedule of the fittings.
We will come back to this later, as we would like to tell you first about the legal obligations entailing your future construction.
