What slows a Faversham project down
Faversham's conservation requirements and the lead-time on heritage materials (peg tiles, oak, lime mortar) are the two biggest sources of delay we see. We pre-order long-lead items before we start on site to keep the programme.
- • Conservation officer requesting material samples (add 1–2 weeks)
- • Bespoke joinery lead-times — typically 4–6 weeks from sign-off
- • Engineer revisions if structural assumptions change once opened up
- • Client decision delays on finishes (we set a "lock-by" date per stage)
In short
12–22 weeks on site for a house extension in Faversham, plus design and planning lead-time. Every project gets a written week-by-week programme up front.
Programme questions we get from Faversham
Can a house extension in Faversham be done faster than 12 weeks?
Occasionally — small straight refits with no structural change can run shorter, but we don't quote unrealistic programmes to win work. A 12-week minimum is what we deliver to.
Do you work on site every day in Faversham?
Monday to Friday 7am–5pm, Saturday morning when programme needs it. Faversham's residential conservation areas have noise restrictions we comply with.
What happens if you run over the programme?
Contract has liquidated damages clauses on programme slip caused by us. Weather and client variation changes are flagged in writing as they happen so the programme stays accurate.
Can we live in the house during a house extension in Faversham?
For loft conversions and most kitchen / bathroom refits — yes, with one room out of action at a time. For full house extensions opening up the back of the property, moving out for 4–6 weeks is usually easier.
