Bohemia House

Works are nearing completion with contractor Jamie Allez Construction to the extension and significant reconfiguration of Bohemia House. We couldn’t be happier with the quality of work and patience on site to achieve the meticulous detailing throughout the project. From backlit recessed skirtings that wrap vertically up the face of walls, to vertically clad hidden joinery details, everything is pulled together by a seamless polished plaster floor. The home presents an open living space broken in plan through dramatic changes in volume, height, lighting and material. It takes a lot of dedication and passion from the client, architect and contractor to commit so fully to achieving this level of detail, and we cannot wait to see it all finished and lived in.

In Planning

We have recently submitted planning for an extension to a family home on the west coast, tucked away behind the sand dunes. The site topography means that the proposal will be unseen from the road, retaining the existing traditional frontage, whilst providing increased bedroom accommodation and generous living space opening onto the south facing garden. Importantly it rationalizes the varied levels across the site and establishes a level point of entry, and the functional arrangement of space for our client to live their way.

La Vallette Development

Vive La Vallette

We are pleased to announce that we have been chosen as the preferred bidder for the development of La Vallette Bathing Pools. DLM are a central member of the not-for-profit group ‘Vive La Vallette’ and during the last few months we have been working to develop a proposal that will enhance the area for the whole community. 

We now have a four month exclusivity period, which will allow us to engage with numerous stakeholders and the public to further develop our plans. 

“We are really excited about the potential for La Vallette and our ideas for the area will take in the arts, the natural environment and physical and mental health and wellbeing. This will be something not for an exclusive group, it’s for the whole community.’

In Design

SLA is an exciting new build concept for a large family home overlooking the west coast. The scheme is configured to respond to the sloping site typography and will be nestled under a cluster of large pine trees. A carefully selected material pallet will ensure the building, although bold in form, blends seamlessly into the surrounding landscape. We are developing further detailed drawings over the coming months.

The Barn

Works are progressing well on site at the Barn.  The cantilevered staircase and bridge have been fabricated and installed by Stainless Steel Fabrications and the reclaimed oak treads are being CNC machined at Swan joinery and assembled ready for fitting when decorations complete.  The double height lobby blends a contrast of traditional reclaimed material with modern engineered fabrication techniques, providing a soft and natural transition between the protected structure and internal fit out.


Planning approval has been achieved for the remodel and extension to a bungalow on an elevated west coast site, forming a generous single level family home. The proposal seeks to re-configure and expand the floor plan, utilising existing structure and providing an open plan living space to fully capitalise on the views and better address the level changes across by the site. Planners commented ‘The proposed building is a well designed dwelling which has been designed taking the site’s topography and surroundings into account’


At DLM Architects there is nothing we love more than a good model.
Getting hand’s on and engaging in physical model making is an invaluable tool that we use to investigate and test our ideas. It is a integral part of our design process, and is usefull at every stage, from testing simple concepts, to communicating more developed schemes.

By making physical models, we are able to bring our ideas out of the ‘2D’ – of sketches and drawings, and into a three-dimensional form. This is typically much easier to understand, and will often allow us to take a different point of view on an idea, highlighting things which are not as clear on paper.

Finally a physical model is one of the most communication tools at our disposal; not everybody is able to read plans fluently, but nearly everyone will have an innate understanding of proposal when it is committed to physical form. This is effective for demonstrating ideas and principles to clients, planners, consultants and contractors, and really helps to open up a discussion.

Another tool at our disposal is the use of digital models. By producing a three dimensional digital model we are able to quickly test and iterate our ideas, at every stage of the design, from loose massing concepts, to specific interior design.

Digital modelling also opens up the world of Architectural visual visualisation. The basic principle is using the digital model to produce a ‘photograph’ of our proposal. We are able to construct a scene digitally, or superimpose onto a real photograph. The later is particularly useful for example when demonstrating how an extension might look on an existing building.

Architectural visualisation allows us to experiment with different material options, furnishings, and conduct accurate and realising daylight simulations for any given scheme. We use this as an essential part of our process as we refine a design.

GSPCA Wildlife Hospital

GSPCA & DLM Architects launch design and build campaign for new GSPCA Wildlife Hospital.

DLM and the GSPCA are delighted to showcase the proposed designs for the new GSPCA Wildlife Hospital.

Having worked with DLM previously the GSPCA approached David De La Mare to help design a much-needed new Wildlife Animal Hospital. DLM understand the limitations the GSPCA face with their existing building stock, much of which is requiring significant investment to ensure it is fit for purpose. The team at DLM have created a design that will meet the current and future needs of wildlife on the island.

David De La Mare Director DLM Architects said “As a chartered architecture practice we have a responsibilty to design buildings that have a positive impact on our natural environment through sustainable intervention. This can range from thermal performance, energy consumption, building materials, planted walls and roofs, and aesthetic appearance to the specific use of the building. The proposed wildlife centre will allow the GSPCA to work more efficiently and cope with the increasing demand on injured wildlife in a purpose built space giving the animal the best chance of recovery and integration back to the wild. DLM Architects is a team of animal lovers and whilst we enjoy designing a building within a detailed criteria for the benefit of our local wildlife, it is also very rewarding to show our support for the great work done by all at the GSPCA.”

“The design has evolved primarily from the requirements of the brief, isolating various species within suitable zones and necessary room size in relation to the duration of treatment required. Consideration has been made to minimise ongoing maintenance costs, centralise storage, administration and cooking facilities, and reduce the trauma of moving the wildlife to and from the relevant zones. The overall form has been developed to respond to the topography and orientation of the site, locating treatment rooms to the outskirts of the footprint where the wildlife will endure less disruption from the central circulation space. We have also considered how fundraising can be integrated into the design and construction of the building and these ideas will be launched a little further into the project.”

Steve Byrne GSPCA Manager said “The GSPCA are hugely grateful to DLM Architects who have listened and understood our requirements and turned them into this wonderful design. We believe this much needed purpose-built Wildlife Hospital will enable us to meet the growing demands of wildlife on our island.”

The Barn

Works continue on site with the conversion of a protected 18th century barn. The existing granite shell and been completely repaired and repointed with hydrated lime, replacing all rotten timber lintels with granite. Internally the structure has been fully waterproofed and insulated with replacement concrete ground and first floor slabs providing a robust and thermally efficient envelope. Glulam A-frames and purlins support a new slate roof with several rooflights providing natural light and ventilation to the vaulted and double height spaces below. Combining carefully selected natural materials and finishes to compliment the historic structure, with the latest technology, offers the performance of a modern family home whilst retaining the character of the original building.

Les Massies

Works are nearing completion with contractor CA Duquemin, to this single storey extension to a traditional Guernsey farmhouse.

The extension replaced a conservatory and reconfigured the kitchen to provide a larger open plan living and dining space with associated utility and plant. The room volumes are far more suitable to modern living, with abundant natural light and improved connection to the maturely landscaped surroundings.

The design incorporates an exposed oak frame spanning between a granite retaining wall and the original house, with structurally glazed elements framing key views, and drawing light deep into the plan.
