How we work
Our process
Consultation, survey, design, build, completion. Five stages, each with a defined output, so you always know where the project is.
In detail
What happens, and when
Most of the anxiety around building work comes from not knowing what is supposed to happen next. This is what does.
-
01Consultation
We sit down with you and your planning representatives to turn a rough idea into a defined brief — what is possible, what it is likely to cost, and what the realistic programme looks like.
-
02Survey
A full measured survey of the property. We check structure, services, drainage, party wall implications and access before a single figure goes on paper.
-
03Design
We collaborate with your architect, structural engineer and consultants through drawings, building regulations and planning so the design is buildable as well as beautiful.
-
04Build
Qualified, directly-employed craftspeople on site to an agreed programme, with a single point of contact, weekly progress updates and a clean, protected site throughout.
-
05Completion
Snagging walked with you room by room, certificates and guarantees handed over, building control sign-off, and a site left cleaner than we found it.
Money
How pricing and payment work
The commercial side, set out plainly, because this is where most disputes in our industry start.
Written and itemised
You get a breakdown of what is included and, just as importantly, what is not. Provisional sums are identified as provisional rather than buried.
Stage payments
Payments are tied to completed milestones, not to a calendar. We do not ask for a large deposit before work starts.
Variations in writing
If the scope changes — because you have changed your mind or because the building has surprised us — it is priced and signed before it is carried out.
Contingency
We recommend holding ten to fifteen per cent on a period property. Unspent contingency stays yours; it is not a fee.
Why Dion
Why clients choose us
One accountable contractor
Structure, carpentry, electrics and plumbing handled in-house. No chasing five different trades for one snag.
We speak architect
We work alongside your designers and engineers from concept, so drawings arrive on site already resolved.
Fixed, itemised pricing
A written breakdown before work starts. Variations are agreed and priced in writing, never sprung on you at the end.
Programmes that hold
A dated programme at the outset and a weekly written update against it for the life of the project.
Respect for your home
Dust sheeting, floor protection, sealed zones and a daily clean-down. Most of our clients live in the property while we work.
Certified and insured
CSCS and CITB certified, Trust A Trader vetted, fully insured, with building control sign-off on every notifiable job.
FAQs
Process questions
All 33 London boroughs plus the immediately surrounding counties. Our office is in Enfield in North London, so North and East London are our busiest areas, but we work across the whole of Greater London.
Yes. We visit the property, survey what is actually there, and provide a written, itemised quotation. We do not price significant work from photographs or a phone description, because quotes produced that way are the ones that change later.
Yes — we hold public liability insurance and can provide certificates on request. We are also CSCS and CITB certified and a vetted Trust A Trader member.
Against an agreed schedule of stage payments tied to completed milestones, not a large deposit up front. Any variation to the scope is priced and agreed in writing before it is carried out.
We work alongside your architect and structural engineer on the technical content, liaise with building control and arrange the staged inspections. Where you do not have a designer we can introduce you to practices we have built with before.
For most single projects, yes — loft conversions and extensions in particular. For a whole-house renovation involving a rewire and replumb there will usually be a period where it is not practical. We tell you honestly at survey rather than after you have committed.
Dion Construction Ltd is a well-established North London contractor with more than 120 completed projects and long-standing commercial clients who have used us repeatedly over a number of years.
Our workmanship is warranted and manufacturer guarantees are registered in your name. If something needs attention after handover, you call the same number you have used throughout the project.
