Bespoke flush casement timber windows with leaded glass detailing installed throughout this Edwardian home near Wandsworth Common.

Energy-efficient, draught-proofed timber windows designed to preserve period character while improving comfort and performance across a prominent bay-fronted facade.

Featured Ranges in Our Earlsfield Installation

The flush casement timber windows installed at this Earlsfield property were chosen for their understated, traditional styling. The flush design allows the sash to sit level within the frame, creating a smooth, elegant finish that complements the property’s prominent bay windows and detailed brickwork.

Finished in RAL 9016 (standard white), the windows offer a classic and neutral appearance, with each unit fitted with polished chrome ironmongery, adding a refined, high-quality touch. Another key feature of this installation was the use of custom leaded glass detailing within the double-glazed units, which replicated the original decorative pattern.

Timber Casement Windows in South London

This detached Edwardian property on Lyford Road, Earlsfield, just moments from Wandsworth Common, features a symmetrical facade and brickwork typical of homes in this part of South London. We were appointed to design and install classic flush timber casement windows throughout, complete with bespoke leaded glass detailing. 

The result is a careful balance between maintaining the home’s heritage proportions and delivering the benefits of modern, high-performance timber windows tailored to suit this distinctive period property.

Project Details & Challenges

This property on Lyford Road is a well-preserved example of Edwardian architecture, defined by its symmetrical facade, detailed brickwork, and large bay windows that frame the front elevation. The homeowners sought to upgrade the original timber windows while retaining the property’s distinct period style.

One of the main challenges was replacing the windows without disrupting the rhythmic symmetry of the facade, particularly important with the full-width bays. Each new window needed to match the exact dimensions and sightlines of the originals.

Another focus was the integration of leaded designs into double-glazed timber units. This required a careful balance between visual authenticity and thermal performance. With several elevations and bay structures to address, precise coordination was needed to ensure a smooth installation across the entire property.

About Our Timber

All our timber windows are made using high-quality, sustainably sourced materials chosen for their durability, performance, and finish. We primarily work with two premium timber types:

European Redwood is a dense, slow-grown softwood known for its strength and dimensional stability. It provides an excellent base for paint finishes and is ideal for projects where a smooth, uniform appearance is required.

Red Grandis, a premium hardwood, offers a finer grain and enhanced resistance to movement. It’s especially suited to more exposed locations and clients seeking a high-end natural or stained finish.

All of our timber is FSC-certified, meaning it comes from responsibly managed forests that meet the highest environmental standards. Every window undergoes a multi-stage finishing process, including anti-rot treatment, microporous primer, and two factory-applied topcoats, ensuring long-term protection against the elements.
