Four steps, one estimate
Start from your house
You draw the existing home or begin from a matching starting plan.
Describe what it is made of
Answer a short questionnaire: the year it was built, its wall materials, its services and its envelope.
Plan the changes on the drawing
Knock through a wall and place a beam and columns, add an extension or a new storey, convert the loft, or move windows and replace finishes.
Get your estimate
The result is an itemised estimate with an honest price range and a construction timeline.
Lynx compares the two states line by line
It works out what must be demolished and what gets built new, estimates the waste, and says whether you need a building permit and a structural engineer.
See exactly what stays, what goes and what is new
Before-and-after plans and a colour-coded 3D view show exactly what stays, what goes and what is new, so you can decide with the full picture in front of you.
