These are only for ideas

Choose The System

Weight sash windows

If you're working on a period property or want a more traditional look, weight sash windows are the right choice. They use a classic weight and pulley system — hidden inside the frame — to make the sashes move smoothly and stay balanced.

This setup is often required in listed buildings or conservation areas, where keeping the original appearance matters. It also adds a level of detail and authenticity that spring systems can’t match.

  • Traditional mechanism – Weights and pulleys hidden inside the frame

  • Authentic style – Ideal for heritage homes and period renovations

  • Smooth operation – Balanced sashes that are easy to open and close

  • Conservation-ready – Meets typical planning requirements in listed areas

These windows take more work to install, but if you care about getting the details right, they’re worth it. We’ll build and fit them to match your property, with clean lines and the right finish.

Spring Sash Window

If you want the look of sash windows without the bulk of a traditional setup, spring sash windows are a solid option. They use a spring-loaded mechanism instead of weights and pulleys, so there's no need for hidden weight boxes — which means slimmer frames and more glass.

They’re easier to maintain, cost less to install, and work well in both modern homes and refurbishments where space is limited but style still matters.

  • Slimmer frames – No weight boxes means more light and cleaner lines

  • Lower cost – Quicker to install and more budget-friendly

  • Easy to use – Smooth, reliable operation with less maintenance

  • Classic look – Keeps the sash window style without the traditional setup

If you’re not restricted by heritage rules and want a more efficient solution, spring sash windows give you the look without the complexity. We’ll make them to fit your space and finish them the way you want.

Sash Wood Styles

  • Box Sash window supplier in London

    Box Sash Window

    If you're restoring a period home or working in a conservation area, box sash windows are the right choice. These are traditional sash windows that use a weight and pulley system, with the counterweights hidden inside a full box frame. That’s what gives them their name — and their smooth, balanced movement.

    Box sash windows are typical of Georgian and Victorian homes. They’re often required for listed buildings, where keeping the original look is part of the planning rules. But even outside heritage projects, they offer a timeless design that adds real character.

    Key Features

    Timeless Design: Retains the classic charm and elegance of traditional sash windows, making them perfect for period properties and conservation areas.
