Gibberd’s New Town
Harlow was designated a new town on 25 March 1947, and Frederick Gibberd’s masterplan shaped almost everything that followed. The town was built as a series of neighbourhoods separated by green wedges, and Mark Hall was the first to be finished. Gibberd brought in different architects for different areas, so a street of 1950s terraces in Netteswell can look very different from one in Little Parndon or Tye Green. The Lawn, built in 1951, was Harlow’s first modern-style residential tower block and is now Grade II listed.
The result is a town where most homes date from the late 1940s to the 1970s, many with large, simple window openings and flat or low-pitched roofs. Later expansions at Church Langley, completed in 2005, and Newhall, from the early 2000s, added more recent houses, and the Harlow and Gilston Garden Town is bringing further growth, including land north of the River Stort.
Harlow’s conservation areas and Article 4 direction
Harlow District Council is the planning authority and has ten conservation areas. Unusually, several protect New Town housing as well as older settlements:
- Mark Hall North and Harlow Garden Village Estate, both covering planned twentieth-century housing;
- Old Harlow, Harlowbury, and Harlow Mill and Old Road North around the older town;
- Churchgate Street, where an Article 4 direction confirmed in force from 4 March 2026 means certain changes to houses need planning permission;
- Netteswellbury, Puffers Green, Town Park Netteswell Cross and Tye Green.
If your home is in any of these, check with Harlow District Council before changing window styles, frame colours or materials. Elsewhere, like-for-like replacements are usually permitted development, but flats, including the many maisonettes and blocks in the town, have no householder permitted development rights and often need freeholder or council landlord consent. Our planning guide has more detail.
Getting the right product for a Harlow home
For a typical New Town terrace or semi, the priority is usually warmth and low maintenance at a sensible cost, which is where our UPVC windows and doors on the Selecta Advance 70 system fit in. A composite front door improves security on homes that still have an original or early replacement door.
Gibberd-era houses with wide horizontal windows can also look very good in slim aluminium. Reynaers SlimLine 68 aluminium windows, an outward-opening casement, along with Cortizo and Alunet ranges, can respect the clean lines these houses were designed with. At the back, a Reynaers ConceptPatio 130 sliding door or a Smart Visofold bifold opens up a kitchen; see our patio doors. For extra space, consider a conservatory, orangery or roof lantern.
Homes near the Stort, on the northern edge of town, are worth checking against the Environment Agency flood map before planning an extension.

Distance, survey and fitting
Our only premises are at Coningsby Farm, Fifield. Harlow is roughly 55 miles away by road, usually around an hour and a quarter via the M25 and M11. Because of that, we plan surveys and installations in advance and group the days together, rather than offering same-day call-outs.
Your surveyor will measure each opening and talk through options and any planning points. You will then get a written quote. Aluminium windows start from £400, and our double glazing cost guide explains the rest. Aluminium frames are made in our workshop with lead times from 10 days, fitted by our own team, and covered by a 10-year guarantee. We are a listed Reynaers at Home installer partner and hold Constructionline Silver. We do not make timber windows.

Frequently asked questions
Do I need planning permission for new windows in Mark Hall North?
Mark Hall North is a conservation area, so check with Harlow District Council before changing the design, material or colour of your windows. Conservation area status can affect what is acceptable, especially on frontages. Tell our surveyor your address and we will plan the specification around the council's advice.
What is the Churchgate Street Article 4 direction?
Harlow District Council made an Article 4 direction for the Churchgate Street conservation area, confirmed in force from 4 March 2026. It removes some permitted development rights, so certain changes to houses there need planning permission. If you live in Churchgate Street, ask the council whether your window or door replacement is covered before ordering.
Can you replace windows in a Harlow maisonette?
Yes, with the right approvals. Maisonettes and flats have no householder permitted development rights, so planning permission may be needed, and you will usually need consent from the freeholder or the council if it is your landlord. Once you have that, we can survey, manufacture and fit as normal.
How far is Harlow from your base?
Our workshop is in Fifield, near Windsor, roughly 55 miles from Harlow by road, which is usually around an hour and a quarter via the M25 and M11. We do not have a local office or showroom, so we plan surveys and installation days ahead and bring samples to your home.
Which windows suit a 1950s Harlow New Town house?
Many 1950s Harlow homes have wide, simple window openings. UPVC windows on the Selecta Advance 70 system are a cost-effective choice, while slim aluminium frames such as Reynaers SlimLine 68 suit the clean modernist lines. Our surveyor will look at the house and the street and suggest what fits best.
