Marshalswick Rear-Extension Flooring: Herringbone & Parquet Flooring Fitted
Kitchen extensions are the busiest flooring category we quote in Marshalswick. Most are rear extensions or side-returns on Victorian, Edwardian or 1930s 1930s semi homes, adding 12–25m² of new floor to a kitchen that already exists. The floor has to blend — same board, same direction, same level — even though the two subfloors are 100 years apart.

Getting the height transition right in Marshalswick rear extensions
Where the two levels genuinely can't be matched (rare, but real), we design a two-step visual transition with a matched threshold ramp — never a 'hope no-one notices' butt-join.

Making the extension read as one floor with the existing kitchen
On Marshalswick kitchen extensions we specify the whole floor — extension plus retained kitchen — as one order, from one batch. Trying to match into a 5-year-old kitchen board never works; the new boards read fresh, the old ones read weathered. Better answer: re-do both, so they're the same age from Day 1.

Kitchen Extensions in Marshalswick — questions
- How long does a full Marshalswick kitchen extension floor take to fit?
- 5–7 working days for a typical Marshalswick rear extension (18–25m²) plus retained kitchen, including UFH commissioning, subfloor levelling and silicone perimeter.
- How much does a Marshalswick kitchen extension floor cost?
- Typical Marshalswick 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 Marshalswick 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 Marshalswick extension over UFH?
- Yes — engineered wood is the ideal spec for Marshalswick 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 Marshalswick 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.
- Can I blend a new extension floor into my existing Marshalswick kitchen?
- Yes — but the winning strategy is to re-do both floors together, from one batch. Trying to match into an existing floor almost always shows the join. Costs more but reads seamless.
