You’ve got drawings. Maybe a quote. But no one’s written down what’s actually being built.
That’s where problems start.
At SpecWorks.uk, we write clear, builder-ready specifications for domestic projects — extensions, loft conversions, internal refits, you name it. Our job is to protect you from vague allowances, scope creep, and costly misunderstandings.
Most domestic projects fall into trouble not because of the work — but because nobody agreed what the work actually was. If it’s not on paper, it’s up for interpretation. And interpretation leads to arguments, extras, and stress.
A written specification (or schedule of works) makes sure everyone’s working from the same page — literally..
No software. No fluff. Just clarity.
The JCT Home Owner Contract is a simple, official agreement used across the building industry. It sets out:
– What’s being built
– Who’s responsible for what
– When it should be finished
– What happens if things change
It’s ideal for domestic extensions, lofts, and renovation projects. You don’t need a lawyer — just a good specification to go with it. We’ll help you fill it in properly, and your builder gets clear rules from day one.
Please reach us at contact@specworks.uk if you cannot find an answer to your question.
Yes. Drawings show layout and size — but not finishes, materials, or standards. A spec fills the gap.
“From the foundations to the roof—including walls, insulation, windows, doors, plumbing, electrics, plastering, and finishes—all broken down clearly so nothing gets missed. We can even include items like your chosen kitchen if you send us the details.”
No. If it’s more than a few hundred pounds, a written schedule is worth it. It stops disputes before they start, we would advise that all major domestic work such as extensions and loft conversions should have a written spec (scheduled of works)
Yes. A written spec helps both sides. It gives the builder a clearer idea of what’s expected — and gives you something to fall back on if anything is missed.
That’s fine. Our spec can be used to test whether that quote is covering everything. If it is — great. If it’s not — you’ll be glad you checked.
“A basic single-storey extension spec starts from around £250, depending on the job. A small price for a big piece of peace of mind.”
