There’s barely a spare corner in the finishing area of our joinery workshop at the moment. Everywhere you look, there are timber windows and doors waiting for the next step.

We make our timber windows and doors to measure and finish them in our Orpington workshop. Our own team fits them on site.

It’s a busy time for us, and we’re still taking on new projects. If you’re planning new timber windows or doors for your home, get in touch. We’d be happy to talk through your options.

A day in our joinery workshop.

There’s usually more than one job on the go. While one order is being machined, the next might already be ready for finishing.

It all happens in our Orpington workshop, where we manufacture made-to-measure timber windows, doors and other joinery in-house for projects across London and the surrounding areas.

Two floors, two bespoke timber bay windows, one beautifully symmetrical design.

Each six-section bay features timber casement windows and a distinctive curved external sill, carefully designed to complement the architecture of the building.

From manufacturing in our Orpington factory to installation on site, every element is made to measure and fitted by our experienced team.

The installation of these timber bay windows requires precision, careful alignment and attention to detail, particularly when working with multiple sections that need to come together seamlessly.

Traditional design, skilled craftsmanship and a consistent finish across both floors.

Our painter is brilliant at what he does. And when he takes a well-earned holiday or needs a sick day, our paint shop can keep moving.

Here, our spray robot is applying primer to a timber door leaf. One stage in the process, before the finishing coats. Automation supports our skilled team and gives us flexibility to keep production running.

Our bespoke timber windows and doors are manufactured in-house at our Orpington factory.

Afraid of spiders? Not us🕷️ Especially when they help us lift 300kg of glass.

With Halloween just around the corner, here’s a different kind of spider in action.

Installing large aluminium windows on the first floor isn’t always straightforward, especially when a single glass unit weighs 300kg.

For this installation, we worked alongside specialist crane operators, using a spider crane and vacuum lifting equipment to position the glass safely. Our team guided the unit into its previously installed aluminium frame, carefully securing it before releasing the lifting equipment.

Heavy glazing installations are something we’re very familiar with. With the right equipment, experience and teamwork, even the biggest panes can be handled with precision.

Some spiders are definitely welcome on our building sites🕷️

One front door, two carefully chosen colours.

Made to measure in our Orpington factory, this bespoke timber front door is finished in Farrow & Ball Serge No. 9919 on the outside and Little Greene Slaked Lime Deep 150 on the inside. Both the frame and door leaf have a semi-matt finish.

Decorative arches and raised panels give the design its character. The sandblasted glass toplight carries the house number, 98, while a Banham lock in polished gold and antique brass door furniture complete the look.

Finished in our factory and ready for installation.

The room is still taking shape. Its window colour is already part of the plan.

Finished in Farrow & Ball India Yellow No. 66 inside and Reduced Green No. 313 outside, this fixed timber casement window follows the same approach as the rest of the property: a consistent exterior, with internal colours chosen to suit the individual rooms designed by Project Home.

Manufactured in our Orpington factory, it was glazed directly into the frame on site by our experienced fitters, who also fitted the trims and completed the silicone finishing.

The surrounding internal work is still unfinished. We’re looking forward to seeing how the yellow comes together with the completed interior.

One colour outside, a different one in nearly every room.

These timber sash windows share the same exterior finish, while their internal colours were chosen to complement the room schemes designed by Project Home.

Antique brass locks and opening restrictors bring a consistent finish across the different internal colours, while decorative sash horns add traditional character to the exterior.

The house is still under construction, with internal finishing around the windows yet to be completed. We’re looking forward to seeing these colours alongside the finished interiors.

These dual-colour Vertical Sliders were made in our Orpington factory and installed by our experienced fitters.

Three doors, one house, and no two of them doing the same job.

The timber front door has a more formal character, with decorative glazing, shaped panels and traditional details. The residential door and stable door take a simpler approach, with routed panels and lever–lever handles. On the stable door, the top and bottom sections open independently, adding flexibility to everyday use.

A shared colour, RAL 7032, and polished gold ironmongery bring all three together. Each entrance has its own purpose and character, while the consistent finish keeps the overall design connected.

All three timber doors were made to measure in our Orpington factory. Planning more than one door for a home? It’s worth thinking about them together.

One frame, two colours. Designed by Project Home, manufactured and installed by Grabex Windows.

Made in our Orpington factory, these French doors with sidelights are finished in Farrow & Ball Reduced Green No. 313 outside and India Yellow No. 66 inside. Clear glazing above raised panels gives them a traditional look, complemented by a heritage-style handle and concealed hinges in antique brass. The hinges stay hidden when the doors are closed.

We glazed the sidelights on site to keep the construction lighter for carrying to the rear of the house. Our experienced fitters completed the glazing and hinge adjustments while the surrounding building work continues.
