Welcome to Ellis Construction Services
Ellis Construction Services grew out of years working alongside architects and landscape designers across the city — we saw too many good drawings let down by building work that was rushed, under-specified, or handed to whoever was cheapest that week. We run every job the way a technical drawing is read: measured first, agreed in writing, then built to the millimetre.
On Site
In Cambridge
House Extensions
Single and double-storey extensions, orangeries and side-return builds matched to your existing brick and roofline.
Loft Conversions
Dormer, hip-to-gable and mansard conversions that add a full storey without touching your footprint.
Renovations & Refurbishment
Whole-house refurbishments, kitchen and bathroom strip-outs, and period property renovation done with care.
Groundworks & Foundations
Excavation, drainage, footings and concrete groundwork — the part of the job that decides what lasts.
New Build Construction
Self-build and infill new homes managed from planning drawings through to a finished, warranted property.
Maintenance & Repairs
Ongoing maintenance contracts for landlords, schools and estates — roofing, brickwork and structural repairs.
Fixed price, in writing
Every job gets a written specification and price before a tool touches site.
One point of contact
A named project manager runs your job start to finish.
Fully insured
£2m public liability cover, and accreditation applications in progress with the FMB and SafeContractor.
Tidy, considerate sites
Fenced and swept daily, neighbours notified before disruptive work.
What Our Clients Say
They gave us a fixed price for the extension and stuck to it — no surprise invoices at the end.
Site was left tidy every single day, and our project manager rang us weekly. Made a stressful job calmer.
We've used them for three maintenance contracts across our estate now. Same team, same standard.
Working towards Federation of Master Builders membership and SafeContractor approval — applications in progress. Gas work is carried out by Gas Safe registered engineers and electrical work certified under Part P. More on our accreditations
