NEW Project - Battersea, Aspect 4 Construction, Residential extension and refurbishment

A little behind the scenes of what we’re working on at the moment…

We’re at the early stages of a new project supporting Aspect 4 with Cost management of their newly awarded project that we also helped tender for.

Before the job really gets moving, the priority is making sure the commercial side is properly nailed down, with a clear scope, pricing that can be defended, and a clear view of where the risks sit early.

That is often the bit that protects profit long before the site starts.

Project type: Extension and refurbishment of the existing residential property.
Location: Battersea
What we’re supporting: Tendering and Cost management

We love working with contractors like Poole Construction because they care about doing it properly.

Here is what they had to say :

"CNJ have been a great support to our business, particularly with estimates. Their work is detailed, well-structured, and easy to follow, and they’re always happy to talk through assumptions, exclusions, and any areas that need refining as a project develops. We’d happily recommend them to any contractor looking for a reliable estimating/QS partner"

We’re trusted by contractors, architects, and developers because we keep it transparent, practical, and grounded in the realities of delivery.

If you’ve been burned by unclear agendas or fuzzy cost positions before, we’re happy to talk through a better way.

“POV: You thought the quote was done… then the client asks one question”

If your tender answer is “I think”… that’s commercial exposure.

Clear scope, measured take-offs and explicit assumptions stop small questions turning into expensive arguments.

👷‍♂️ CNJ provides independent, contractor-side cost support, from accurate pricing and tender clarity through to commercial control on live projects. If you want to protect margin and reduce the admin burden that pulls you off site, get in touch and we’ll talk through how we can support your next project.

When the market gets tighter, the cracks show faster.

Costs move.
Labour gets stretched.
Clients push harder.
Contracts get tighter.
And suddenly all the loose bits in a job start getting expensive.

That is usually when people realise how much a good QS matters.

Not just for pricing the work…
but for protecting the margin, tightening the scope, keeping procurement under control, and making sure valuations and variations do not turn into a monthly headache.

In an easier market, people can sometimes get away with being a bit loose.

In this one, that gets punished quickly.

Quoting is one of those things that looks “free” until you add up how much it’s actually costing you. 😅

Time.
Admin.
Take-offs.
Subbie pricing.
Revisions.
Chasing.

And if you are winning 1 in 5, that one job is having to pay for a lot more than people realise.

That is why better quoting is not just about looking professional.
It is about protecting time, improving win rates, and making the numbers work harder.

“We’ll sort it on site” has probably eaten more margin than most people realise. 😅

When measurements are rushed, the problem does not go away.
It just gets passed forward.

Into your pricing.
Into your programme.
Into your variations.
Into all the awkward conversations later.

The builders who protect margin best are usually not doing magic.
They are just getting clearer earlier.

If you want to explore what support looks like for your type of projects, we are happy to have a conversation.

We have been working on small extensions, new build houses, medium and large commercial works, and plans for a new roller coaster at one of the UK's most popular theme parks.

We’re looking forward to supporting the next batch of projects and helping keep budgets and margins on track.

If you’re pricing work at the moment and want a stronger commercial position before you commit, we’re happy to have a chat.

Phasing is often sold as “flexible”… but it’s rarely cheaper.

When a project is split across years (phase 1 in 2025, phase 2 in 2026, phase 3 in 2027) you’re not just delaying work, you’re multiplying cost drivers: repeated prelims, lost buying power, extra design rounds, repeated mobilisation, and longer overhead exposure.

Phasing can be the right decision… as long as the commercial reality is priced properly at the start.

At CNJ, we help contractors and developers sense-check phased strategies early and quantify the cost impact before commitments are made.

If you’re looking at phased delivery and want a clear commercial view, we’re happy to help.

Contractor-side. Defensible. Trusted.

Contractors don’t come to us for “a price” they come for a commercial position they can stand behind.

CNJ exists to support contractor decision-making at the points where risk is created: pre-contract pricing, tender submissions, and live project cost control. We’re independent, commercially focused, and experienced in the realities of delivery, which is why we’re trusted by contractors, architects, and developers.

If you want clearer numbers, fewer assumptions, and more control from tender through to delivery, we’re happy to talk.

We’re getting close to our £10,000 target.

For those of you who may not know, Joshua, our Founder, and his family, for the last two years, have been supporting their son Winter’s fight with severe epilepsy.

Winter has already been through major surgery, with more still to come, and his courage through all of it has been incredible.

To give something back, Joshua is taking on 100km from London to Brighton in under 24 hours alongside Megan and Holly, making it a real team effort.

Together, they are raising money for Great Ormond Street Hospital Children’s Charity and are now getting close to that £10,000 target.

It is a challenge with purpose, to give something back to the teams who have given so much to Winter and to so many other children and families.

If you’re able to support, it would mean the world.

And if donating isn’t possible, sharing this post is hugely appreciated too.

Thank you for supporting Winter, Joshua, Megan, Holly, and the incredible teams helping save children’s lives every day.
