Howard Pease Architects has extensive experience and expertise in working with locally listed buildings and Conservation Area properties in Harpenden and St Albans. The unique constraints and issues surrounding these projects means that a full understanding of the planning department's specific design criteria for redeveloping Conservation Area properties is essential to arrive at an appropriate solution that still meets the client's needs.

The properties were built by Oakbridge Homes and are laid out over three floors with the style matching the Edwardian houses in the road. A large family living area was created as the focal point of at the back of the new house opening on to the rear garden area.


two storey extension of locally listed house, Park Avenue North, Harpenden conservation areaThis Locally Listed house on Park Avenue North Harpenden benefitted from a carefully considered rear two storey extension as well as a single storey extension providing a more open and spacious kitchen dining family room area. Understanding the Conservation Area issues relating to such older houses was essential resulting in a planning approval being achieved at the first application.

modernisation in a conservation area West Common Way, HarpendenHoward Pease Architects were asked for this major Conservation Area project to completely modernise, redesign internally and extend sympathetically this period house in West Common Way, Harpenden.

It was essential that the new and existing parts of the property blend together so well that they cannot be distinguished apart. The careful choice of matching materials was an important part of this process.

The whole house was also completely refurbished and modernised inside giving the client a luxury family home.

conservation area HarpendenLocated in the centre of Harpenden within the Conservation area, this pair of semi detached houses were almost completely re built to give accommodation over three floors. The split level plan to the rear responded to the sloping site condition and meant that the new large dining area opened more directly onto the patio garden space. Although a major project on a sensitive site, this potentially difficult to extend conservation property achieved planning at the first attempt.

The architectural style and character of the new house was to match that of the other period properties in the road. The layout internally is more open plan with a double height main living area, top lit and overlooked from the first floor gallery landing.

architects extension to an arts and crafts house in the conservation area of HarpendenLocated within the Conservation Area of Harpenden, the original Arts and Crafts house had been untouched for many years and had fallen into disrepair.

It was essential in this case to be sympathetic to the architectural style of the original Locally Listed house.
