Project types

Extensions, conversions, self-builds, renovations and small commercial fit-outs — what screeding each project type actually involves, start to finish.

The screed decision looks very different on a rear extension than it does on a barn conversion or a shop fit-out, even when the area is identical.

These pages walk through the common project types we are asked about, and the build-up, sequencing and programme issues each one brings.

Single-Storey Rear Extension

A rear extension usually means matching a new floor build-up to an existing house level while adding underfloor heating, so junction detailing and depth planning matter more than raw floor area.

Wrap-Around Extension

Wrap-around extensions create a larger, often L-shaped open-plan floor than a simple rear addition, which changes how heating zones, pour sequencing and access are planned.

Two-Storey Extension

A two-storey extension typically needs two different screed approaches — a heated ground floor build-up and a lighter upper floor solution suited to the structural deck below it.

Whole-House Renovation

A whole-house renovation strips floors back to sub-base or joists across every room, giving the opportunity to specify one consistent, heated screed floor throughout rather than patching room by room.

Kitchen Remodel

A kitchen remodel puts more emphasis on a dead-flat, level surface for large-format tiles or stone than on heating output, and often has to match the level of an adjoining hallway or dining space.

Bathroom & Wet-Room Floors

Bathroom and wet-room floors need falls to a drain built into the screed itself, plus careful sequencing with waterproofing, which sets them apart from a standard flat room pour.

Open-Plan Knock-Through

Knocking two or more rooms into one open-plan space often exposes that each room was built to a slightly different floor level, which a new screed can resolve into a single flat surface.

Orangery

Orangeries have more glazing and a lantern roof than a standard extension, so the floor build-up leans on underfloor heating and insulation to offset the additional heat loss.

Garden Room / Annexe

A standalone garden room or annexe is screeded as its own small, independent structure, which brings different access and heating considerations to a house extension.

Granny Annexe

A granny annexe is generally built for full-time living rather than occasional use, so the floor is specified around accessibility, level thresholds and a reliable, consistent heating output from day one.

Self-Build New Home

Self-build clients often manage their own trades directly rather than through a main contractor, so clear communication about programme, specification and site readiness matters as much as the pour itself.

Custom-Build Plot

A custom-build plot sits within a wider serviced site but is designed and built individually, meaning the floor specification is bespoke to that plot even though roads, services and access are often shared.

Small Housing Site

A small housing site of several plots benefits from a repeatable screed specification and a pour schedule that keeps pace with the wider build programme across all units.

Apartment Block / Upper Floors

Upper floors in apartment blocks need acoustic separation between units as much as a flat surface, and delivery logistics are shaped by lift or hoist access rather than ground-level pump positioning.

Listed-Building Sympathetic Works

Working in a listed building means the floor specification has to respect existing fabric, moisture movement and any conditions attached to listed building consent, not just current best practice for a new floor.

Side Return Extension

Side return extensions squeeze extra kitchen and dining space out of a narrow side passage, and a pumped liquid screed copes well with the tight, awkward shape.

Kitchen-Diner Refit

A kitchen-diner refit often means stripping the existing floor back to the slab and starting again, and liquid screed provides a genuinely flat base for the new finish.

Garage Conversion

Converting a garage into a habitable room usually starts with the floor, since garage slabs sit lower and are less insulated than the rest of the house.

Barn Conversion

Barn conversions bring their own floor challenges, from uneven original ground levels to large open-plan spans, and liquid screed adapts well to both.

Garden Office

A garden office needs a comfortable, level floor within a compact footprint, and liquid screed with underfloor heating suits these small insulated buildings well.

Bungalow Renovation

Bungalow renovations often involve reworking the entire ground floor at once, and liquid screed's single-pour coverage suits that scale of project well.

First-Floor Screed

Screeding upper floors in a new-build home calls for particular attention to weight, acoustic performance and drying, and liquid screed is regularly specified for the job.

Basement Conversion

Basement conversions bring particular challenges around headroom, damp management and access, and liquid screed offers a shallow, level solution.

Loft Conversion Floor

Loft conversions call for careful attention to floor weight and depth, and lightweight liquid screed formulations can help keep the build-up within the available headroom.

Conservatory Replacement

Replacing an ageing conservatory with a solid-roof garden room or orangery-style space is a good opportunity to upgrade the floor to a warm, level liquid screed.

Utility & Boot Room Extension

Utility and boot room extensions take a lot of daily wear, and a level, hard-wearing liquid screed base helps the final floor finish perform well over time.

Office Fit-Out Screed

A fast, low-height liquid screed system suited to office refurbishments where programme certainty and a genuinely flat floor matter more than anything else.

Retail Unit Fit-Out Screed

A pumpable liquid screed solution for shell-and-core and refit retail units, poured to suit shop-fitting timescales ahead of finishes and shopfronts.

Restaurant & Café Floor Screed

A level, robust screed base for restaurant and café fit-outs, tailored to the different demands of front-of-house floors and commercial kitchen areas.

Gym & Studio Floor Screed

A flat, well-consolidated screed base for gyms, fitness studios and yoga spaces, laid to support rubber, sprung timber or resin flooring above.

Veterinary & Clinic Floor Screed

A flat, dependable screed base for veterinary practices, clinics and consulting-room fit-outs, chosen to support hygienic, washable floor finishes.

Nursery & Preschool Floor Screed

A flat, warm floor base for nursery and preschool fit-outs, frequently specified with underfloor heating to keep low-level play areas comfortable.

Church & Community Hall Floor Screed

A level screed solution for churches, chapels and community halls, suited to large open floor areas and often installed alongside underfloor heating upgrades.

Holiday-Let Refurbishment Screed

A warm, level screed solution for holiday-let refurbishments, planned around the tight off-season windows that many self-catering properties rely on for building work.

Student Cluster Flat Screed

A repeatable liquid screed build-up for student cluster flat developments, laid across multiple study bedrooms and shared kitchen and living areas within a fixed academic-year deadline.

Care Home Refurbishment Floor Screed

A flat, warm screed base for care home refurbishment projects, planned carefully around residents and staff so occupied areas are disrupted as little as possible.

Mixed-Use Development Screed

A flexible liquid screed approach for mixed-use developments, addressing the different floor build-ups and programme demands of commercial and residential space within the same building.

Phased Multi-Plot Housing Screed

A plot-by-plot liquid screed service for phased housing developments, matched to build programmes, site logistics and staggered NHBC-style handover dates.

Pool Houses & Spa Rooms

Pool house and spa floors combine constant humidity, standing water and chemical splash with a need for gentle, even underfloor heat, making screed build-up a critical part of the design.
