Kitchen Extension Herringbone & Parquet Flooring — Croxley Green, WD3
Kitchen-extension Herringbone & Parquet Flooring in a Croxley Green home is a level-matching, batch-matching and UFH-commissioning job before it's a board-fitting job. We plan all three before ordering material — because you can't unfit a 40mm board mismatch after the fact.
Blending new extension floors with existing kitchens in Croxley Green
For 1930s semi Croxley Green kitchens where the retained floor is Victorian solid pine and the extension is a new engineered oak, we design a deliberate transition — solid oak threshold band between old and new. Reads intentional, not retrofit.

Level, thickness and step control on Croxley Green extension floors
The new screed in a Croxley Green kitchen extension is rarely at the exact height of the existing kitchen subfloor. On our surveys we measure both — target is under 3mm difference across the join. Above 3mm and we ramp with a matched threshold; above 8mm and we level with SLC before fit.

Getting the heating right in a new Croxley Green extension floor
Glue-down to screed on 1930s semi Croxley Green extensions gives the best heat response and eliminates drum-resonance on a hollow-sounding floor. On Croxley Green extensions we glue-down 85%+ of UFH installs.
Kitchen Extensions in Croxley Green — questions
- How long after the extension is finished can I fit the floor in Croxley Green?
- New screed needs 1 week per centimetre to dry — a 75mm slab needs 7–10 weeks before flooring is safe. Dehumidification can accelerate; guessing cannot. We CM-test on every Croxley Green extension fit.
- How long does a full Croxley Green kitchen extension floor take to fit?
- 5–7 working days for a typical Croxley Green rear extension (18–25m²) plus retained kitchen, including UFH commissioning, subfloor levelling and silicone perimeter.
- How much does a Croxley Green kitchen extension floor cost?
- Typical Croxley Green extension (20–25m² new + 10m² retained kitchen) in engineered oak with UFH: £3,800–£6,400 fitted. In LVT: £2,200–£3,900. Both include commissioning and silicone perimeter.
- How do I match the level between my Croxley Green extension and existing kitchen?
- Under 3mm difference we ramp with matched threshold. Above 3mm we level with self-levelling compound before fit. We measure both levels on the survey and price accordingly.
- Can I have engineered wood in a Croxley Green extension over UFH?
- Yes — engineered wood is the ideal spec for Croxley Green extensions over UFH. Certified UFH-compatible ranges, glued down to screed, run at up to 27°C surface temperature. Solid wood cannot go here.
- Do we need to remove existing kitchen units on a Croxley Green extension floor job?
- Usually no — we fit up to the plinth line with colour-matched beading. Only jobs where the kitchen is being replaced anyway get full floor-under-cabinets install.
