What we build in Wandsworth
We only offer services in Wandsworth that suit its buildings and market. These are the projects we are asked for most here:
Prime residential refurbishment
Prime residential refurbishments in Wandsworth: 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 Wandsworth by our in-house team: space planning, joinery design, lighting, materials and finishes, carried through to delivery so the finished home matches the drawings.
Permitted development & prior approval
Permitted development checks and prior approval applications for Wandsworth properties, including lawful development certificates, so you know which route applies before you spend on design.
Planning consultancy & permission
Planning consultancy for Wandsworth: pre-application advice, planning and listed building consent applications to London Borough of Wandsworth, and the drawings and reports that go with them.
Planning, consents and site rules in Wandsworth
Local authority: London Borough of Wandsworth. Before any design is fixed we check the planning and ownership position for your address, because in Wandsworth this decides what is possible and how long it takes:
- Several Wandsworth neighbourhoods are conservation areas with extension guidance.
- Permitted development rights often apply outside conservation areas.
- Party wall agreements are standard on terraced streets.
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 Wandsworth
Is my extension permitted development?
It depends on the house and location. We check the rules for your address and apply for a lawful development certificate or planning as needed.
Can you manage design and build?
Yes, one team from design to handover.
How much does a project in Wandsworth 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 Wandsworth 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 Wandsworth?
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 70% 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 Wandsworth project.
