What we do
From a single extension to a whole new home.
Extensions, loft conversions, renovations and new builds for period, listed and contemporary homes — plus garden rooms, commercial work and the trades that go with them. One firm, one standard, across Tunbridge Wells, Kent & East Sussex.

01
Home Extensions
Single and multi-storey rear and side extensions, built to last
Extending a home is our core work. Harlequin design and build single-storey and multi-storey rear and side extensions across Tunbridge Wells — from a light-filled kitchen-diner to a whole new wing — with the structure, glazing and finish all handled by one firm.

Loft Conversions
Dormer and zinc-clad conversions — master suites and extra bedrooms
A loft is often the most valuable room a period home can gain. Harlequin convert lofts into master suites, bedrooms and bathrooms — dormer and zinc-clad dormer conversions worked carefully into the existing roof of Victorian townhouses and other period homes.

Renovations & Refurbishment
Full ground and first-floor refurbishments, including listed work
Renovating an older home well means getting the things you don't see right as well as the things you do. Harlequin take on full ground and first-floor refurbishments — including sensitive work to listed period properties — coordinating every trade so the standard holds across the whole home.

New Builds
Bespoke contemporary homes, from demolition to completion
Some sites are better started again. Harlequin take on demolish-and-rebuild projects and bespoke new builds — contemporary homes with spray render, timber cladding, large windows and separate annexes — managed from demolition through to a finished house.

Garden Rooms & Offices
Timber-framed, larch-clad garden offices — a proper room outside
A garden room is one of the most useful spaces a home can add. Harlequin build timber-framed, larch-clad garden offices — properly insulated, wired and finished — with WiFi, remote lighting and app-controlled alarms, so it works as a real room all year round.

Commercial & Property Maintenance
Offices, schools and ongoing maintenance for property agents
Alongside our residential work, Harlequin take on commercial building — offices and schools — and provide ongoing property maintenance for letting agents and property management agencies across the Tunbridge Wells area.

Carpentry & Joinery
The joinery a good build is made of
Carpentry runs through everything we build. Harlequin handle the structural timber, first and second fix and fitted joinery that an extension, conversion or renovation is built on — done by the team running the whole job.

08
Plumbing & Heating
New heating, bathrooms and the pipework a build runs on
Plumbing and heating sit at the heart of every renovation and extension. Harlequin handle new heating systems, bathroom plumbing and underfloor heating as part of the build, so the services are designed around the finished home.

09
Electrical & AV
From a small alteration to a full rewire — including data and AV
Refurbishments and new builds need their electrics done properly and in the right order. Harlequin handle everything from small alterations to complete rewires, including data, audio and visual installations, as part of the build.

Plastering
The flat, true surface a good finish needs
Plastering is the quiet trade that decides how good the decoration looks. Harlequin handle the skimming, floating and rendering our builds need, so walls and ceilings are flat and true before a brush touches them.

Painting & Decorating
The finishing coat that ties the whole project together
Decoration is what pulls a build together. Harlequin finish the projects they build — proper preparation and filling, then a clean, precise final coat — so the last thing you see matches the standard of everything underneath.

12
Patios & Decking
Finishing the garden the extension opens onto
An extension or garden room is only finished when the space outside it works too. Harlequin lay patios and decking and carry out the hard landscaping that connects a new build to the garden around it.

Property Maintenance
Ongoing maintenance for homes and managed property
Not every job is a full build. Harlequin also provide ongoing property maintenance — for private homes and for the letting agents and property management agencies we work with around Tunbridge Wells.
