Local knowledge & expertise

If you’re looking for the best architects working in Hertfordshire and interested in massively effective projects delivered on time that need minimal revisions, you’re going to love working with us

Since 2013, we’ve been working with the planning and building control departments of all the Hertfordshire councils on projects from extensions to new build houses, so we know their local planning policies, building regulations and requirements inside out.

The majority of our projects take place in the areas covered by North Hertfordshire, Stevenage, East Hertfordshire, Dacorum, St Albans, Welwyn Hatfield, Broxbourne, Three Rivers, Watford and Hertsmere district councils.

Most of our work in Hertfordshire happens in Cheshunt, Waltham Cross, Hoddesdon, Hemel Hempstead, Berkhamsted, Tring, Bishop's Stortford, Buntingford, Sawbridgeworth, Ware, Borehamwood, Potters Bar, Bushey, Letchworth Garden City, Hitchin, Baldoc, Royston, Harpenden, London Colney, Redbourn, Stevenage Old Town, Rickmansworth, Chorleywood, Croxley Green, Welwyn Garden City, Welwyn Village, Hatfield and Old Hatfield.

Recognised as one of the best residential architecture firms in the South-East of England, we work across the entire residential architecture spectrum with construction budgets of 100k - 10m. With a proven track record delivering home extensions, flat conversions, HMOs, new build houses and flats, we deliver incredibly successful projects for national house builders and seasoned property developers right through to first-time investors and homeowners.

What makes Hertfordshire special?

Hertfordshire starts on London’s northern border and yet also runs up to the Chiltern Hills Area of Outstanding Natural Beauty. Much of the county other than the big towns lies in the Green Belt – if you live in a Hertfordshire village, this will be (in the jargon) “washed over” by the Green Belt, meaning its rules apply there.

St Albans is the county’s only city and has ancient roots, first as a Celtic settlement and then as Verulamium, the second-largest city in Roman Britain.

There are a number of spectacular stately homes in Hertfordshire, including Hatfield House, a Jacobean masterpiece. Hatfield House also has a surviving wing of a Tudor palace. Open to the visiting public, it’s also a frequent movie location. Moving on a century and a half to the 1770s, we get the Palladian grandeur of Gorhambury House.

You can also visit the ruins of Old Gorhambury House, its Elizabethan predecessor. Grade-II* listed Knebworth House shows off the Gothic revival style of the Victorian era at its most extravagant, although the estate is probably most famous – at least for Brits of a certain age – as the location for huge rock concerts, including Led Zeppelin in 1979 and Oasis in 1996.

The architecture of Hertfordshire

You can get a good sense of the full span of British history in Hertfordshire, from Roman remains through to considerable surviving medieval and Tudor buildings through all the eras since. In Hertfordshire, you can see some of the great experiments in creating fully planned new settlements: the garden city of Letchworth, founded at the start of the 20th century, and the post-Second World War New Towns of Stevenage, Hatfield and Hemel Hempsted. Welwyn Garden City is the link between the town: founded by Ebenezer Howard in 1920, it was designated as a New Town in 1948.

The garden city movement has left a legacy of long, low houses with a ground floor and then the first floor partly in the pitched roof. Redbrick is the dominant building material. Certainly to anyone more used to big city life, homes in Hertfordshire outside of the medieval towns tend to seem refreshingly spacious. Towards the south of the county, as you get towards the capital, you see more of the yellow London stock brick.

Planning applications in Hertfordshire

In the year ending June 2020, all the Hertfordshire councils received 11,293 planning applications. The approval rate was 79%, which is substantially below the English average of 87%. Different district councils have very different records, ranging from North Hertfordshire (93%), Stevenage and Dacorum (both 92%) to Watford’s 68%, which is one of the lowest approval rates in the whole country.

Our expertise in planning applications means we have a 97% success rate of getting planning permission for our clients (across all councils). Hertfordshire is a place where we have a deep knowledge of the workings of the local authorities. As our client, we will increase your chances of getting planning consent for your project.

Most popular projects for homeowners

Our projects for homeowners in Hertfordshire range from home extensions, loft conversions, full house refurbishments and barn conversions. We also have substantial experience in projects located in the Green Belt. This includes getting planning permission for houses using all the exceptions allowed under the regulations, including Paragraph 80 houses (aka Paragraph 55 houses) in the countryside.

Whether you want a house extension that will transform how your house feels inside and out or you have a large plot you want to build a new house on, we would love to help.

Most popular projects for developers

Our projects for developers in Hertfordshire range from listed building renovations to medium-scale new build housing schemes in the Green Belt. We have a strong track record of getting the most from constrained plots with planning restrictions.

Whether you want to make changes to a listed building, breathe life into a neglected midcentury new townhouse or are aiming to build new homes in the Green Belt, we’ve got the skills and knowledge to turn your wishes into reality.
