How is residential measured under RICS NRM2?

Whether pricing a rear wrap-around extension in Kent, a loft dormer in London, or a 24-dwelling residential parcel in Yorkshire, we measure every domestic trade—from strip footings and party-wall steelwork to Part L insulation, roofing, kitchens, and external paving.

Explicitly separates strip-out, temporary propping/needling, and party-wall protection from new fabric works on UK extensions and Victorian terrace alterations.
Highlights Approved Document Part L, Part F, and Part O compliance cost drivers cleanly.

Measurement & Deliverable Parameters

How are UK residential takeoffs structured for tender accuracy?

Residential Estimating — UK Measurement Units, Deliverables & Workflow Specification
Estimating Parameter	Technical Specification	Standard / Audit Basis
Work Breakdown & Units	NRM1 / NRM2 Housing Elements in m2, m3, m, nr, item	Scaled PDF / DWG plans at 1:50 & 1:100 (dimensions in mm / m)
Waste & Prelim Separation	Net physical takeoff plus 5%–10% typical trade waste split	Keeps net order counts transparent for merchant tenders
Deliverable Workbook	100% unlocked formula Excel + colour-coded PDF overlays	Includes formal RFI log flagging drawing ambiguities
Turnaround & File Transfer	24–48 hrs (domestic/single trade) · up to 25 MB uploads	3–5 working days typical for multi-trade commercial tenders

Calibration note: 1:50 and 1:100 architectural and structural drawings are scaled to 25 mm masonry tolerances and 100 mm thermal zones, isolating 5 percent to 10 percent wastage from net quantities.

Residential Estimating FAQs

Can you separate demolition/strip-out from new construction in refurbishment jobs?

Yes. Existing removal, propping, waste skips, and make-good allowances are itemised separately from new-build elements.

Do residential estimates help win homeowner jobs with transparent breakdowns?

Yes. You get an internal cost workbook plus a clean room/element summary tab structured for UK domestic tender proposals.

Can you price multi-plot house types from a single typical unit plus sitework drawings?

Yes—house types are measured once per archetype and multiplied cleanly across your site layout, paired with bespoke plot foundations and external civils.
