How realistic are builders initial costings? Watch John talks more about this topic which we come across regularly.
At the end of last year we celebrated planning success for our new build home in Drax Avenue. 4 months later, after a thorough competitive tender process we are on the precipice of signing the construction contracts. We are only a few weeks away now and can’t wait to break ground with the client on this project.

While we wait for professional photographs of the new interiors of the house by, we bring you some externals of our recently completed
‘restoration’ projects on Belvedere Avenue in the heart of Wimbledon Village. Refurbishments of houses which are very specific architectural styles is something we relish; you could say sub-genres to a main genre. This large Edwardian Arts & Crafts house, more in the style of
‘Norman Shaw’ with the large Oriel window and covered porch has a restrained feel to it’s elements and detailing.
Together with the client who had recently purchased the property, we decided the best course of action was to restore the original fabric to new as opposed to large scale interventions. We added a new boundary treatment in the style of ‘Bedford Park’ in Chiswick, one of Norman Shaw’s most notable historic projects to enhance the style of the existing house. We feel the best Architectural proposals look as though it may have always been there, and we hope to have achieved that with this project.

At Dyer Grimes Architects we do not posses a specific set architectural style as such. Our dextrous team of Architects are highly skilled and knowledgeable in a variety of building styles, both modern and traditional and we believe each project has a different set of requirements one must adapt to. 
Our latest projects in Wimbledon Village is a perfect example, where the client owns a very large and quite plain rendered house and wishes to adopt a more international ‘LA’ style rear extension and modifications to their home. We were quickly able to come up with some loose concept designs of the rear façade and interior layouts based on some of the home she had been inspired by, passing this information over to our independent QS, EleyQS to carry out a cost estimate so we could very quickly establish if their brief was in line with their budget. A great client and a project we are really looking forward to seeing this take shape in the latter half of 2026.
 
Project led by DGA directors John-Dyer Grimes & Harrison Groot.
The appointment of an architect is rarely given the weight it deserves, yet it defines the trajectory of the entire project.

Beyond aesthetics, it calls for demonstrable expertise, sound judgement, and the support of a capable team able to navigate complexity with consistency. These early decisions shape not just the design, but the clarity and confidence with which a project moves forward.
A basement is not simply an extension of space below ground, it is an engineering exercise defined by what lies beneath.

Ground conditions, water levels, and soil composition introduce variables that must be understood in detail before any design is resolved. Without that insight, risk is introduced early, often revealing itself later in costly and avoidable ways.
When working on historic buildings we often come to the realisation amazing and conscious design work has already been completed, but some 100-200 years before our involvement. Things do not always require redesigning. Often they are already fully resolved. They just require careful consideration and restoration. The facade of this beautiful Grade II listed townhouse along Clapham Common North Side is such an example.

What stands out most is the quiet elegance of the façade. It feels both refined and lived-in. The warm, textured brickwork has a beautiful rhythm, especially with the contrasting red brick arches framing each window. The repeated window shapes create a strong sense of symmetry, but the slight variations and the natural aging of the materials keep it from feeling rigid.
The sash windows themselves are tall, evenly spaced, and painted in a soft crisp white that contrasts the earthy tones. 

Above, the roofline adds character with its dormer windows and chimneys, giving the building a layered, almost storybook silhouette without being overly ornate.
We also love how the entrance is understated yet inviting. The small portico and muted green door provide just enough contrast to draw your eye without overpowering the rest of the structure. And the wrought-iron fence in front adds a touch of classic urban charm, creating a gentle boundary while still keeping the house visually connected to the street.

Listed buildings and conservation areas come with rules - and no two are quite the same. Every location has its own planning constraints, and understanding them early makes all the difference. Whether it’s navigating permissions or working within heritage guidelines, the right approach helps turn complex projects into achievable ones.
For this special master en-suite, our clients came to us seeking a restorative and organic sanctuary that avoided the clinical feel of typical modern bathrooms. Collaborating closely to bring their vision to life we anchored the space with a bespoke warm oak double vanity featuring rich reeded detailing, fulfilling their desire for mid-century tactile warmth. To complement the timber, we incorporated vertically laid, sage-green kit-kat mosaic tiles and wall-mounted brushed brass taps over a crisp marble-effect worktop, ensuring the clutter-free quiet luxury they requested. We then softened the room’s linear architecture with charming scalloped-edge brass mirrors and ribbed glass wall sconces and grounded the entire scheme with a large-format terrazzo floor that seamlessly tied the earthy greens and warm wood tones together into the serene, cohesive retreat they had always hoped for.

Designing a family home today isn’t about creating a showpiece - it’s about planning for real life. From multi-generational living to future mobility needs, smart design looks ahead. Features like adaptable spaces and even lifts aren’t just practical, they can add long-term value too. A home should grow with you, not work against you.
This homage of ours to Pitshill House in West Sussex is an all-time favourite of our Directors Philip and Harrison. Their view is it is one of the most beautiful country homes ever built.
 
Constructed in 1794 this Grade II* listed house is built in neoclassical style. At the heart of the landscape sits a stately manor that echoes the precise, mathematical symmetry central to Palladian design. Its crisp, ashlar facade features a distinct central projecting bay capped with a prominent classical pediment. Along with its tall evenly spaced sash windows the building’s strongly reflects the 18th-century British enthusiasm with Andrea Palladio’s architectural principles.
 
With a reflecting pool reflecting the strict symmetry of the facade, the misty trees and the golden morning sky, beautifully amplifying the homes stately presence. The grounds feature a seamless transition from the rigid geometry of the house to the natural landscape. Directly in front of the building are manicured terraced lawns, low hedges, and precise, spherical topiary, which gently give way to the sweeping, open parkland.

John talks through the importance of integrating a new extension with the existing building, rather than allowing it to feel like an afterthought.

The starting point is always the original architecture. Every building has its own character, from the proportions of its windows to the materials, detailing and overall rhythm of the façade. When those elements are properly understood, they give you a clear direction for how an extension should be approached.
Craft. Space & Time.
John explains part of the early construction process, focusing on the structural work happening below ground level.

Circular concrete columns are drilled around 10 metres into the ground, forming the foundations of the build. Once in place, the surrounding earth is excavated to create what becomes a concrete box, the base structure that everything else will sit on.
This doorway is a perfect example of why symmetry doesn’t always have to be followed slavishly. The left-hand side sash windows help turn the corner and provide dual aspect windows to the room to maximise views out into the corner of the garden.
 
The entrance is crowned by a prominent, closed triangular pediment finished in stepped leadwork, supported by a simplified entablature consisting of an unadorned pulvinated frieze and a stepped architrave. Directly below, a segmental fanlight bridges the doors and the pediment. This fanlight features a classic radiating sunburst pattern formed by slender mullions.
 
Looking into the guest wing beyond an enfilade neatly arranges the doorway and the front window beyond, strengthening the connection to the bedroom and creating a greater impression of space.

Steel reinforcing bars, shaped, cut and tied together on site to form the framework of a reinforced concrete beam.

Each section is set out to the engineer’s exact specification before concrete is poured over the top, combining the tensile strength of steel with the compressive strength of concrete. Every measurement matters at this stage, because once it’s cast, it’s there to stay.
John has spent the last 30 years building a supplier network who care about quality, detail, and getting it right first time.

From hand-selecting marble in person to sourcing heritage mouldings, it’s about making the right choices early on, because those decisions shape everything that follows.

We love a stunning kitchen. Kitchens matter to families for much more than just cooking; they’re often the emotional and practical ‘centre’ of the home. Families naturally gather in the kitchen. Whether it’s chatting while dinner cooks or grabbing a quick snack, it creates everyday moments to talk, bond, and stay connected. This kitchen, in our home Wildwood is by @blakesldn

Our interior designers at @gordondufflinton created this artistic visualisation to show exactly how the finished room will look and now we’re into the first stage of making it real.

The carcasses are in, the steel bedhead reinforcement is set for the floating design, and we’re preparing the air conditioning slot to keep everything sleek and hidden.

The goal is a hotel-style finish, where every detail works without interrupting the look.

As with all our projects, the style of the interior design of our new-build house in Harpenden from 2024 is moulded to our client’s particular preferences.

We involve our clients every step of the way. Every project we undertake is a reflection of the people we design for. We take the time to understand each client’s tastes, vision, and lifestyle, allowing these elements to shape every decision; from layout and materials to the smallest finishing details. Rather than imposing a signature style, we adapt and evolve our approach, ensuring that each space feels personal, functional, and truly aligned with how our clients live. The result is not just a beautifully designed interior, but a space that feels authentically theirs and one they feel they have designed

Excavation work is well underway in Richmond where our team is delivering a £2.6m new-build residential project in partnership with @thamesandnewcastle 

We’re maximising space on this narrow plot, creating a circa 200 square feet basement. This specialist work is being carried out by our in-house team to seamlessly integrate the basement construction into the wider programme.
