We completely understand the frustration. You’ve got a clear vision for your barn conversion, home extension, or dream new build, you’re excited to get started — and then… weeks go by while you’re waiting for a quote.
It’s enough to drive anyone round the bend.
But here’s the truth: there’s method in our madness, and it all comes down to making sure your budget is right from the start.
Every Project Is Different (and That’s a Good Thing)
Unlike putting together a quote for a kitchen worktop, barn conversions, renovations, and major extensions are incredibly complex. No two properties are the same — and that means no two quotes ever will be either.
That Victorian farmhouse you’re extending? It might have limestone foundations that need specialist work.
That 18th-century barn you’re converting? It could have oak beams that need structural assessment before we even start pricing timber.
We’re not just counting bricks and tiles. We’re:
Assessing soil conditions and groundworks
Checking for asbestos or hidden defects
Measuring for bespoke joinery and finishes
Calculating insulation and thermal performance upgrades
Considering access routes for deliveries and machinery
Factoring in current building regulations and planning conditions
Every detail affects the final cost — and every detail matters.
We Don’t Believe in Guesswork
The truth is, rushing a quote often leads to nasty surprises later. Too many homeowners are burned by builders who quote low to win the job, then add “unexpected extras” once work begins.
That’s not how J&K Developments operates.
When we give you a price, we want it to be accurate, transparent, and dependable. That means taking the time to get it right — not pulling a number out of thin air that doubles halfway through your project.
Our Commitment to Transparent Pricing
We know that budget is everything when you’re planning a major build. That’s why we’ve refined our quotation process to be as clear, efficient, and honest as possible — without cutting corners.
Here’s what you can expect:
10–14 working days for a detailed barn conversion quote
7–10 working days for a straightforward extension or renovation
Faster turnaround where possible — and clear communication if more time is needed
During that time, we’re not just sat in the office with a calculator. We’re:
Liaising with structural engineers and planning authorities
Checking current material prices and supplier availability
Consulting with our trusted tradespeople to confirm realistic labour times
Ensuring your design meets all building control and insulation standards
Factoring in fair contingencies for those inevitable “while we’re at it” extras that every homeowner adds mid-project
So when your quote lands in your inbox, you can trust that it’s based on real numbers, not rough guesses.
Why Accuracy Matters – Materials and Quantities
Here’s a quick look at some of the most common building materials used in construction and renovation — and why accurate pricing makes all the difference:
Material | Why It Matters | What We Consider in Your Quote |
|---|---|---|
Bricks & Blocks | Structural integrity and insulation | Wall thickness, brick type, mortar quantity |
Timber | Framework, roofs, and bespoke joinery | Moisture content, treatment, and strength grade |
Steel | Structural support in conversions and extensions | Load calculations, fabrication, and delivery access |
Roof Tiles & Slates | Weatherproofing and appearance | Roof pitch, underlay type, and fixing method |
Insulation | Thermal efficiency and energy savings | U-value targets and regulation compliance |
Windows & Doors | Light, ventilation, and design | Glazing specs, sizes, and energy performance |
Concrete & Foundations | Stability and longevity | Soil conditions, trench depth, and load-bearing capacity |
Every cubic metre of concrete, every steel beam, and every roll of insulation has to be measured, checked, and costed correctly — because getting it wrong can mean overspending later.
That’s why we take our time — to save you money, stress, and surprises in the long run.
