02 What matters to us
Exceptional renovations. Practical priorities.
Construction Worx has built a reputation for exceptional property renovations. At the heart of our approach are three straightforward commitments: reliability, professionalism and affordability.
Professional
We bring design and building expertise together, considering how new spaces look, connect and work as part of your home.
Affordable
We pride ourselves on affordability. A useful starting point is understanding your priorities and the budget you have in mind.
03 Space to stay
A bigger home. A familiar address.
Moving is not the only way to find more space. An extension can give you room to grow while keeping the neighbourhood, connections and everyday routines you value.
We design and build home extensions that include new kitchens, utility rooms, dining rooms and bathrooms. The aim is more than extra floor area: it is a home that works better for the way you live.
Start with what your current home is missing. A sociable kitchen? A separate utility room? More space around the dining table?
Below ground. Beyond storage.
A new purpose for your basement.
Our expertise includes basement excavations and turning underused lower-ground spaces into beautiful, functional rooms. Previous projects have included cinema rooms, gyms, play rooms and even entirely new flats.
Different spaces. Different possibilities.
- Cinema rooms: a dedicated place to settle in and enjoy a film.
- Home gyms: room for exercise within your own home.
- Play rooms: space for family life beyond the main living area.
Experience beyond an extra room.
We have also created entirely new flats from basement space. What is possible for your property depends on its structure, access and the permissions required.
04 Look up
From dusty attic to light-filled living.
We turn unused attic space into modern new bedrooms and bathrooms, filled with natural light. A loft conversion in London can open up possibilities within the roof space you already have.
Good loft bedroom design considers more than the room itself. Headroom, daylight, the staircase and the relationship with the floor below all help shape a space that feels part of your home.

06 Before you begin
A few useful starting points.
You do not need every detail resolved to start a conversation. Tell us about your property and what you would like to change.
What kinds of projects do you take on?
We specialise in home extensions, loft conversions, basement excavations and property renovations in Wandsworth and London. Our work includes new kitchens, utility rooms, dining rooms, bathrooms and bedrooms, as well as basement cinema rooms, gyms, play rooms and flats.
Does an attic conversion need planning permission?
Some attic conversions may fall within permitted development rights, while others need planning permission. The property type, location and proposed roof changes all matter. Building regulations are a separate requirement, so the planning position and technical requirements should both be checked before work begins.
How much does it cost to do a loft conversion?
The cost depends on the roof structure, usable space, access, specification and whether you want to add a bathroom. Share your ideas and any plans through our contact page so we can discuss your project and a quote.
