Working in Garston

What we know about building in Garston

The housing is overwhelmingly mid-century and post-war. A great deal of Garston was built in the 1930s and then extended again through the post-war decades, which gives you the familiar mix of semis with generous rear gardens and reasonably steep roofs, plus the terraced streets and flats that filled in afterwards. It is, in short, close to ideal territory for extensions and loft conversions.

Garston is also unusually well connected — the A405 North Orbital and the M1 at junction 6 are right there, and the Dome roundabout is the local landmark everyone navigates by. That accessibility is part of why the area stays popular with families, and why the housing here keeps being improved rather than replaced.

The semis that make up most of Garston are the reason we do so much work here. They generally have three things going for them: a decent rear garden, a roof pitch that will take a dormer, and a ground floor that can be opened up without touching the structure. That combination means a single-storey rear extension plus a loft conversion can transform a three-bedroom semi into a five-bedroom house without moving a single party wall. The terraces and flats on the estate's later phases have their own logic, and are more often about careful internal reconfiguration than extension.

Planning authority
Watford Borough Council — Garston is within Watford Borough Council, and much of the area is covered by policies encouraging family-sized housing, which is generally helpful for extension and loft conversion applications. There are no large conservation area constraints across most of Garston, which makes permitted development a realistic route for many projects here.

FAQs

Garston questions

Can I extend my Garston semi without planning permission?
In most cases yes, provided the extension complies with permitted development limits on depth, height, materials and the amount of the original garden covered. Garston has relatively few of the conservation area and Article 4 restrictions that affect other parts of Watford, so permitted development is a genuinely realistic route for many of our projects here. We confirm your specific position at the free site visit.
How much space can a loft conversion add to a Garston house?
On the typical 1930s or post-war Garston semi, a rear or full dormer conversion will usually give you a comfortable double bedroom with an en-suite, and often a small study area as well. Where the roof is hipped, a hip-to-gable conversion adds noticeably more usable floor area and is usually worth the extra cost.
Do you do roofing work in Garston?
Yes. A large proportion of Garston's housing is now at the age where roofs need attention, and we carry out repairs and full replacements, re-tiling, flat roof replacement on extensions and garages, and roof window installations. We will tell you plainly whether yours needs replacing or simply repairing.
How disruptive is an extension or loft conversion?
For a loft conversion we make a temporary opening in the roof for access, generally during a defined early phase, so disruption is concentrated rather than spread across the whole job. For an extension we plan the groundworks and the opening-up phase to keep your kitchen and bathroom working for as long as possible.
