For Annie Martin and her younger brothers, Will and Joe, Seacombe will always hold fond memories of childhood holidays and long, hot summers spent playing on the nearby beach. Back then, however, their parents’ seaside holiday home in East Portlemouth, Devon, was little more than a timber shack with a corrugated tin roof and absolutely no mod cons — a far cry from its newly built successor.

Glyn and Jane Martin were initially attracted to the property’s totally secluded setting and the incredible sea views which may be enjoyed from its elevated 1.5- acre site. Accessed by an unassuming stone track off the lane between East Prawle and East Portlemouth it stands above sandy Seacombe beach in an Area of Outstanding Natural Beauty, with spectacular coastal scenery spreading out below.

Project Details

  • Name: Glyn and Jane Martin
  • Build Cost: £350,000 (£1,750/m²)
  • Build Time: 1 Year 5 Months
  • Build Route: DIY and subcontractors
  • Region: Devon

“We loved spending time at the house, despite the fact that it was literally falling down, with just a generator for electricity, gas lighting, no phone and rotten floors,” Annie, now 31, recalls. “My parents originally bought it at auction more than 20 years ago, and over time we extended the 1930s chalet and did it up on a DIY basis.”

Years passed, and when Annie qualified as an architect the family began to consider the possibility of replacing their old single storey holiday home with a new dwelling, specifically designed to take full advantage of the south-facing panoramic views and to provide more comfortable accommodation.

“With no near neighbours we hoped the planners would allow us to build something contemporary,” explains Jane, “but we’re surrounded by National Trust land and there was a covenant which restricted the height of the property, so there were numerous hurdles to overcome before our plans were finally approved after about a year of negotiations.”

In order to reduce the impact of the new two storey building it has been positioned further back on the site and the ground floor was excavated into an existing steep bank. The garage is constructed so that its planted roof is a continuation of the boundary bank — ensuring that the house only comes into view from the track near the entrance gate.

From the north and west it appears to be a modest bungalow, accessed from the driveway by crossing a timber bridge to the cedar-clad entrance. Walk inside, however, and the true nature of the house reveals itself, with huge windows and glazed balconies offering stunning sea views.

Three bedrooms are located on the first floor with two en suites and a family bathroom, which take full advantage of the elevated view. The two main bedrooms both have recessed balconies, which provide sheltered external areas as well as helping to reduce the apparent weight of the first floor by cutting away the corners.

An oak staircase leads downstairs from the main entrance to the spacious living area and a large private walled garden beyond. Finishes are luxurious, with oak and limestone floors, underfloor heating and an air purification system. There’s wi-fi throughout, a bespoke kitchen and a state-of-the-art cinema concealed behind a wheeled ‘bookcase’ door.

“My brothers insisted on a cinema as part of the brief, and we liked the idea of building it within a secret room because the old bungalow had a bedroom extension which could be accessed through a doorway hidden inside a cupboard,” says Annie. “We wanted to keep some references to the original building, such as the external timber boarding, and to choose materials which would be in sympathy with the site.”

The ground floor of the new building is embedded into the bank and has been constructed in solid rendered masonry, with the first floor structure in steel and timber, clad with untreated horizontal cedar boarding. Large areas of glazing are restricted to the south façade and durable zinc was chosen for the monopitch roof which will weather to an inconspicuous matt grey.

“My partner, Mark, is a carpenter who worked fulltime on site during the build, so we decided to move into the old timber bungalow and lived there for 18 months while the new house was completed,” recalls Annie. “It wasn’t too bad during the summer, but in the winter it became really cold and damp, and we were glad to move out in the end.”

Jane and Glyn purchased a caravan so that they too could stay on site and be involved in the build process, with Jane taking a year out from teaching in a further education college. Building was largely completed on a DIY basis with subcontractors used to excavate the site, erect the steel frame and clad the roof with zinc. A glazier, electrician and plumber were also employed.

“As children we’d helped to do up the old bungalow, painting windows and getting involved, and here we were all working together again on its replacement,” says Annie. “In summer it was fantastic to be outdoors in such a beautiful setting, but winter was a very different story in such an exposed location, and the weather could be quite wild.”

Access onto the site was also problematic, and at one stage it was left to Annie to drag a stranded Jewson lorry out of the muddy field using a tractor.

Progress was slower than expected, which encouraged Glyn, with help from the rest of the family, to tackle even more of the work — including installing the ground-source heating, tanking the blockwork, plasterboarding, cladding the retaining perimeter walls with stone, landscaping and much more.

Mark undertook the carpentry work while Jane helped out with insulating, applying anti-corrosion agents to the steel, decorating and replanting the garden.

Stone excavated from the site has been recycled and used for garden and garage walling, a ground-source heat pump from Kensa is employed for the underfloor heating and a ventilation heat exchange provides clean, warm air throughout the heavily insulated house.

“I’m particularly pleased with how well the overhanging roof shades the glass in summer, and yet still allows the lower winter sun to warm the rooms,” says Annie. “The ground floor is largely underground, so this also helps to keep the space at a fairly constant temperature throughout the year.”

It was Glyn who ordered many of the materials, negotiating hard for the best possible prices, while Annie obtained quotes from various subcontractors and Jane kept detailed financial records. “There was no designated project manager, we all worked well together,” says Glyn, an artist.

“Annie worked on site on Mondays, and her detailed plans were consulted to solve every issue. We were nervous about working with our daughter on a professional level, but we’ve been highly impressed with her abilities and, if anything, it has strengthened our relationship.”

With the new Seacombe completed the old timber bungalow could finally be demolished in accordance with planning conditions. At last the Martins are able to enjoy the beautiful coastal setting all year round, retreating to the sheltered balconies and first floor landing ‘lookout’ during particularly inclement weather.

Annie has recently given birth to her and Mark’s first baby, Leah, and can already envisage history repeating itself. “It’s lovely to think that Leah will enjoy the same kind of seaside holidays that we did as children, and we will look forward to spending time at Seacombe with the family,” she says. “Building the house has certainly brought us all closer, and it’s been rewarding to think just how much of the work we managed to complete ourselves.”

It wasn’t just the site that swayed the judges — spectacular though it was. Any old house wouldn’t have made such perfect use of this unique and awe-inspiring setting so the plaudits have to go to the architect — Glyn and Jane’s daughter Annie. Getting coastal homes right isn’t easy — the traditional design solution is to go for an ‘upsidedown’ layout but this usually sacrifices the bedrooms to be small, poky and dark. Here, every room feels like it’s outside and it’s something that works with the site rather than railing against it. This wasn’t simply a spectacular design on an awesome site, but a real gritty self-build story, and a family affair at that. Glyn and Jane spent many hard days on site themselves and that mix of contemporary craft, sustainability and DIY work is very rare, especially in a design of this quality. We also got the distinct impression that this is a home that would be as cosy in winter as it would be serene on summer nights. We don’t know why Glyn and Jane should feel luckier — having a house like this to use when they feel like it or an architect like Annie on tap!
