Question 1

What does a hip-to-gable loft conversion cost in Ruislip or Northwood (HA4, HA6)?

Accepted Answer

Squaring off a hipped-roof semi in HA4 or HA6 to create a full-width habitable room typically costs £55,000–£90,000 finished, depending on dormer specification, staircase routing and fit-out level. The geometry of these 1930s Metroland properties suits the conversion well: extending the ridge to the flank wall delivers space that a simple dormer cannot match. Most HA4 and HA6 properties fall within Hillingdon's permitted-development thresholds, needing a Lawful Development Certificate rather than a full planning submission — but ridge height, roof pitch and Party Wall Act obligations are all confirmed at the survey before the price is fixed.

Question 2

Can I extend the rear kitchen of my Hayes terrace without a full planning application (UB3, UB4)?

Accepted Answer

For most post-war terraces and semis in Hayes, a single-storey rear extension stays within permitted development — 3 m on a terrace, 4 m on a detached or semi — and requires only a Lawful Development Certificate before work starts. The Elizabeth line at Hayes and Harlington has strengthened buyer demand across UB3 and UB4, making a well-specified kitchen extension a sound investment; budget around £40,000–£68,000 fully fitted, depending on structural span and kitchen spec. Every quote we issue breaks each trade and material into its own line.
