Question 1

What does a rear extension and kitchen refit typically cost on an N19 Archway terrace?

Accepted Answer

Budget roughly £57,000–£98,000 for a single-storey rear addition with a fully specified new kitchen on a period Archway terrace. Extension depth, structural opening width, roof glazing choice and the kitchen itself all move the figure. A good number of N19 addresses fall within permitted development limits, though properties near the Highgate fringe can sit close to conservation boundaries or be covered by Article 4 directions — we check the planning position for your specific address when we visit and confirm it in writing alongside the quote.

Question 2

Do I need planning permission to extend my Archway house near the Highgate side of N19?

Accepted Answer

On most residential streets across N19, a single-storey rear extension stays within permitted development, provided it respects the relevant depth, height and materials conditions. Addresses toward the upper part of Archway, close to the Highgate Village boundary, may fall within or adjacent to conservation areas administered by Islington or Haringey — and in those cases an Article 4 direction may require a planning application instead. Because the boundary runs through the postcode rather than along it, each address needs its own check, which we carry out before preparing the quote.

Question 3

Can a loft conversion and rear extension be run as one project on an Archway Victorian terrace?

Accepted Answer

Combining both into a single contract is common on N19 period terraces and usually makes financial sense: the scaffolding, structural engineer's visits and site management costs are shared rather than duplicated, and the trades are sequenced across one programme instead of two. A dormer or hip-to-gable loft conversion added to a rear extension and kitchen refit in the same build typically saves several weeks of disruption compared with separating the projects. Heating work, where it forms part of the scope, is carried out through our Gas Safe registered partner.
