Blackheath combines Georgian terraces and villas around the heath, the Cator Estate and a lively village centre. Projects are typically period-home refurbishments, extensions and interiors.
We are a London-based design and build contractor, founded in 2016, with our office on Buckingham Palace Road. One team takes your project from survey, design and consents through construction to handover — with around 60% direct labour, ISO and CHAS accreditation, a 4.9★ Google rating and every project to date delivered on budget and ahead of programme.
What we build in Blackheath
We only offer services in Blackheath that suit its buildings and market. These are the projects we are asked for most here:
Prime residential refurbishment
Prime residential refurbishments in Blackheath: whole-house and apartment refurbishments, structural alterations, extensions, M&E renewal, bespoke joinery and high-end finishes, managed discreetly with neighbours in mind.
High-end interior design
Interior design in Blackheath by our in-house team: space planning, joinery design, lighting, materials and finishes, carried through to delivery so the finished home matches the drawings.
Residential architecture & design
Residential design and architecture for Blackheath homes: measured surveys, design options, planning drawings and technical packages, coordinated with our construction team from day one.
Planning consultancy & permission
Planning consultancy for Blackheath: pre-application advice, planning and listed building consent applications to London Borough of Lewisham and Royal Borough of Greenwich, and the drawings and reports that go with them.
Planning, consents and site rules in Blackheath
Local authority: London Borough of Lewisham and Royal Borough of Greenwich. Before any design is fixed we check the planning and ownership position for your address, because in Blackheath this decides what is possible and how long it takes:
- Blackheath is split between Lewisham and Greenwich, and much of it is within the Blackheath Conservation Area.
- Many period houses are listed.
- Estate covenants can apply on some roads, adding landlord approval.
We prepare the drawings and statements, submit the applications and build the approval time into your programme — so construction starts on a date you can rely on.

Questions about building in Blackheath
Do you work on listed houses in Blackheath?
Yes. We manage listed building consent and use appropriate materials and methods.
Can you design the extension too?
Yes. Our in-house team designs, obtains consent and builds.
How much does a project in Blackheath cost?
It depends on scope, condition, specification and access, so we don't publish a price per square foot without seeing the building. As a reference, the table above shows what recent Craftex projects actually cost. Our Feasibility & Costing Study gives you a detailed, unit-by-unit cost plan before you commit.
How long will my Blackheath project take?
Programme depends on size, consents and whether the building stays occupied. Our projects have ranged from three weeks for a 750 sq m office refurbishment to seven months for a £2.2M conversion. We give a realistic programme with the cost plan, and every project we have delivered so far has finished ahead of programme.
Who handles consents with London Borough of Lewisham and Royal Borough of Greenwich?
We do. Our design and planning team prepares drawings, applications and method statements, and manages planning, listed building consent, building control and landlord or estate licences alongside the build programme.
Do you use subcontractors?
Around 60% of our labour is direct, and one Craftex project manager controls every trade. That gives you one accountable team, consistent quality and no gaps between designer and builder.
What is the minimum project size you take on?
We typically take on projects from around £100k, from single floors and units to whole buildings.
How do I start?
Send us the address, a short description and any drawings or photos. We arrange a site visit, then prepare a Feasibility & Costing Study with design options, consents, a cost plan and a programme for your Blackheath project.
