Drawings for a whole new home — an infill plot, a backland site or a house replaced with something better on your St Albans land, taken from feasibility through a full planning application with its design and access statement to the building-regs set, coordinated as one package and revised free until approved, with a free plot check first.
St Albans City & District Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Over 80 per cent of the district is Metropolitan Green Belt, the dominant constraint and the reason the emerging plan must justify green-belt release, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. St Albans carries at least one Article 4 direction, and conservation areas including St Albans city centre, Fishpool Street and St Michael's Village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in St Albans is determined against an 8-week statutory target.
St Albans city centre (the medieval and Georgian historic core around the cathedral and Fishpool Street), Harpenden (affluent commuter town of Edwardian and interwar semis and detached houses), Marshalswick (interwar and postwar St Albans suburb of detached houses and semis), Redbourn (historic village with a large common, period cottages and modern infill), Wheathampstead (historic village between St Albans and Harpenden) and London Colney (large village with mixed twentieth-century estate housing) — these are the St Albans pockets our drawings cover most. Heritage designations here include St Albans city centre, Fishpool Street, St Michael's Village, Verulamium, Harpenden and Redbourn. St Albans City & District Council weighs each proposal against the saved 1994 St Albans District Local Plan Review, with a new Local Plan to 2041 at examination, where the historic city core carries dense conservation coverage layered over the scheduled Roman remains at Verulamium. Converted flats concentrate in the city centre and along the commuter-rail corridors, and carry no householder permitted-development rights.. On roofs the borough is pitched plain-clay-tile roofs on the historic core and hipped roofs on the interwar suburban semis, over medieval, Georgian and Victorian stock in the historic city core, Victorian and Edwardian commuter terraces, interwar and postwar suburban semis and detached houses in Marshalswick, Harpenden and the larger villages and period cottages in the green-belt villages.
A new-build application is a different animal from an extension: you are not adapting a house, you are proposing a building where none stands. Across St Albans the opportunities sit in the gaps — an infill plot between two houses, a backland site behind a garden, a large corner or driveway, or a tired bungalow worth replacing with a full house. The medieval, Georgian and Victorian stock in the historic city core, Victorian and Edwardian commuter terraces, interwar and postwar suburban semis and detached houses in Marshalswick, Harpenden and the larger villages and period cottages in the green-belt villages that set the local grain also set the bar the new home is judged against, because St Albans City & District Council weighs whether the design belongs on the street.
The drawings have to make the planning case and the buildable case at once. A scaled site plan fixes the footprint, the boundaries, the parking and the amenity space; the floor plans and elevations show a house that works and reads well; and the design and access statement argues the scheme against the local plan — its scale, its massing, its relationship to the neighbours' daylight and privacy. Over 80 per cent of the district is Metropolitan Green Belt, the dominant constraint and the reason the emerging plan must justify green-belt release, precisely the kind of policy a new-build design has to satisfy from the first sketch.
Where a plot sits in or beside a conservation area — St Albans city centre, Fishpool Street, St Michael's Village, Verulamium, Harpenden and Redbourn among St Albans's — the new house is judged on how it preserves or enhances the character of the place, and a contemporary or a contextual design each has to be justified. The Verulam and Fishpool Street Article 4 direction, covering the historic core around Fishpool Street and St Michael's, removes permitted-development rights so even minor external changes to these medieval and Georgian frontages need consent. We resolve the design approach against the setting before the application is drawn.

Yes — a new dwelling always needs a full planning application to St Albans City & District Council. The design has to answer these questions before it is likely to be approved:
We take the plot from a free feasibility check through the full planning application — site plan, floor plans, elevations and design and access statement — to the building-regs and structural set, coordinating the whole thing so the house that gets permission is the same house that gets built and signed off by St Albans City & District Council.
Below is St Albans City & District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. St Albans grants a fair share of householder applications, with near-total green-belt coverage and the sensitivity of the historic city core the constraints behind most refusals. A new dwelling is a full application judged on design quality — a scheme presented with a proper site plan and design and access statement is far more likely to land than a bare set of elevations.

A new-build permission is won on the argument that the plot can take another house and that the design earns its place. St Albans City & District Council's officers weigh the principle of development on the site, the scale and massing against the neighbours, the daylight and privacy impact, the parking and drainage, and the quality of the design itself. Across St Albans city centre, Harpenden and Marshalswick these are the tests that separate a plot that gets developed from one that stays a garden — and the design and access statement is where the case is made.
The historic city core carries dense conservation coverage layered over the scheduled Roman remains at Verulamium. We often recommend testing the principle first — a pre-application enquiry to St Albans City & District Council, or an outline application to fix the acceptability of a new home before the full design spend — then take the approved principle through to a detailed permission and the building-regs set, so a St Albans plot is de-risked before the money goes in.

We design new dwellings on the infill, backland and replacement plots across the borough. A few of the St Albans neighbourhoods where new-build sites come up most often:
New build drawings for a plot around St Albans city centre's the medieval and Georgian historic core around the cathedral and Fishpool Street — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
New build drawings for a plot around Harpenden's affluent commuter town of Edwardian and interwar semis and detached houses — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
New build drawings for a plot around Marshalswick's interwar and postwar St Albans suburb of detached houses and semis — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
New build drawings for a plot around Redbourn's historic village with a large common, period cottages and modern infill — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
New build drawings for a plot around Wheathampstead's historic village between St Albans and Harpenden — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
New build drawings for a plot around London Colney's large village with mixed twentieth-century estate housing — designed to sit in the street and drawn for St Albans City & District Council's full planning process.
A new dwelling is judged as a building in its own right. This is what the set has to include and what each part is judged on.
| Document | What it shows | Judged on | Stage |
|---|---|---|---|
| Site plan | Footprint, boundaries, parking and amenity space | Whether the plot can take the house | Planning |
| Plans & elevations | The house that will be built | Design quality and how it sits in the street | Planning |
| Design & access statement | The argument against the local plan | Scale, massing, daylight and character | Planning |
| Structural & regs set | Construction, drainage and structure | Buildability and compliance | Building control |
On a plot in a conservation area — such as St Albans city centre and Fishpool Street, green belt or a flood zone — St Albans City & District Council requires further justification before a new dwelling is acceptable.
A staged route that de-risks the plot before the full design spend — the principle first, then the detail, then the build.
Send us the St Albans plot and what you want to build. We check St Albans City & District Council's local plan, the site's designations and the likely acceptability of a new dwelling before you commit to design.
We develop a concept and, where it de-risks the plot, test it with a pre-application or outline enquiry to St Albans City & District Council so the principle of a new home is confirmed before the detailed spend.
We produce the site plan, floor plans, elevations and design and access statement, with daylight/sunlight and drainage information where the site needs it, as a complete application.
We submit to St Albans City & District Council, negotiate the design through determination, then produce the building-regulations and structural set and revise it free until the new home is approved and buildable.
Always. There is no permitted-development route to a brand-new dwelling, so a new house — whether on an infill plot, a backland site or as a replacement — needs a full planning application to St Albans City & District Council. The application is judged on the principle of development on the plot and the quality of the design. We check the plot's realistic prospects against the St Albans local plan before you spend on a full scheme.
It depends less on raw size than on whether the plot meets St Albans City & District Council's standards for a new home — adequate amenity space, parking or access, privacy distances to neighbours, and a footprint that sits comfortably in the street. A garden or driveway that looks generous can still fail on overlooking or access. Our free feasibility check tests your St Albans plot against these before you invest in design.
A design and access statement explains and justifies the design of the new dwelling — its scale, massing, materials and how it responds to the site and the local plan — and most new-build applications in St Albans benefit from or require one. It is where the planning case is argued, so St Albans City & District Council's officer can see the reasoning rather than infer it from drawings. We write it to answer the specific policies your plot engages.
Outline permission fixes the principle that a new home is acceptable on the plot without committing to the full design, which can de-risk a site before heavy spend; full permission settles both principle and detail in one go. For a single dwelling in St Albans we often recommend a pre-application enquiry to St Albans City & District Council first, then a full application, but on a marginal plot the outline route can protect you. We advise which fits your site.
Often yes. Replacing a tired bungalow or small house with a better dwelling is a common and viable route, but it is a full planning application judged on whether the replacement is a proportionate improvement in scale and design — St Albans City & District Council will not simply wave through something much larger. On a plot near a conservation area such as St Albans city centre and Fishpool Street the design is scrutinised more closely. We test the replacement's likely scale before designing.
We price each St Albans new build individually, because the plot, the design ambition and whether the site needs daylight, drainage or ecology support all vary enormously, and send a fixed, no-obligation quote within one working day. It covers the coordinated planning and building-regs set with free revisions until St Albans City & District Council approves.
