EXTENDING IS A POPULAR WAY TO ADD SPACE WITHOUT NEEDING TO MOVE.
If you want to add more space to your home and renovating or converting existing space just isn’t
going to do it, then you should consider extending as this is often a much more cost effective option
to moving once you factor in estate agent / legal fees, moving costs, stamp duties etc. Extending
your existing property can also reignite old flames and help you fall in love with your home all over
THIS IS WHERE AVANT GARDE CONSTRUCTION COMES IN!
Extensions are the backbone of our company and we can undertake any size extension, from a
simple porch to an extremely complex, multiple floor level construction with a fully pitched roof with
or without dormer/s. We have many years of experience and always build to the best building
quality standards and adhere to all building regulations.
DESIGN AND BUILD
To help you get the most from your extension, we offer all our clients a “Design and Build” option where we can assist you, alongside our Architect, on the best and most practical ways to achieve
what you wish for.
HOW MUCH DOES AN EXTENSION COST?
The cost of your extension will be affected by many variables, from soil type (which impacts on the foundations), whether you are building a single or two storey extension, what the extension will be
used for to how much glazing you would like. Depending where you are based in the South East region, you should allow around £1,850 – £2,550/m² for a straightforward extension. Note that the standard of specification you choose will
also have a great influence on the build cost.
