Question 1

What does a rear extension on a Victorian terrace in Hornsey N8 typically cost?

Accepted Answer

A single-storey rear extension on an N8 Victorian terrace — strip foundations, structural steel carrying the original rear wall, a lantern or pitched roof, bifold or sliding doors to the garden, screed floor, and plastered-and-decorated interior — typically falls between £46,000 and £76,000 before kitchen fitting. Variables include ground conditions on your specific plot, the depth of steelwork needed at the junction with the existing house, and whether a Haringey planning application is required or a lawful development certificate suffices. PrimeCraft breaks every element into a line-by-line figure on the day we visit the site.

Question 2

Do Hornsey N8 homes lose permitted development rights for a side-return extension?

Accepted Answer

Many N8 addresses keep full permitted development rights, so a side-return infill can proceed under a lawful development certificate — provided it stays within half the original side-flank width, clears the existing eaves height, and sets back from the front elevation. The complication is that Haringey has issued Article 4 directions on a number of Hornsey roads, withdrawing those rights and requiring a planning application regardless of the size of the proposal. PrimeCraft checks which regime covers your specific address at the survey stage and manages whichever consent route applies through to sign-off.

Question 3

What renovation options make most sense for the Edwardian bay-fronted semis on Hornsey's residential streets?

Accepted Answer

Hornsey's Edwardian semis generally offer four routes worth pricing: infilling the side return to grow the ground-floor kitchen; a rear-dormer loft conversion adding a usable bedroom or study; a full ground-floor reconfiguration opening the front reception through to the back; or a whole-house programme combining new services, refreshed finishes, and careful restoration of original cornicing and picture rails. Where a boiler or heating system needs replacing, PrimeCraft co-ordinates that work through a Gas Safe registered partner. All trades run under one contract with a single point of contact.
