Two-storey extension drawings for Clarendon Park homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Leicester City Council's design guidance, delivered in days and revised free until your decision.
Leicester City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The HMO Article 4 Direction means any new small HMO needs consent, and the council usually refuses further conversions where student occupation is already concentrated, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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. Clarendon Park carries at least one Article 4 direction, and conservation areas including Stoneygate, New Walk and Knighton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Clarendon Park is determined against an 8-week statutory target.
Queens Road (the shopping spine framed by tightly packed Edwardian terraces), Montague Road (grid of red-brick terraces with front bays and small forecourts), Springfield Road (wider terraces edging into the Stoneygate conservation area), Howard Road (student-dominated terraced streets close to the University of Leicester), Avenue Road Extension (later terraces linking Clarendon Park to Knighton) and Clarendon Park Road (the district's namesake terraced street of period frontages) — these are the Clarendon Park pockets our drawings cover most. Heritage designations here include Stoneygate, New Walk and Knighton. Leicester City Council weighs each proposal against the Leicester Local Plan and the council's Student Housing SPD, where the Stoneygate conservation area boundary reaches into Clarendon Park, so frontage, boundary-wall and roof detail are held to conservation standards on those streets. Many Clarendon Park terraces are subdivided into student flats or run as HMOs, and converted flats hold no householder permitted-development rights.. On roofs the borough is gabled and hipped slate roofs on the terraces and rear back-addition roofs shaping side-return schemes, over late-Victorian and Edwardian red-brick terraces, larger bay-fronted villas towards the Stoneygate edge and period houses widely converted to student flats and HMOs.
Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Clarendon Park is largely late-Victorian and Edwardian red-brick terraces, larger bay-fronted villas towards the Stoneygate edge and period houses widely converted to student flats and HMOs, and gabled and hipped slate roofs on the terraces and rear back-addition roofs shaping side-return schemes set what a matching roof actually means here.
The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.
The HMO Article 4 Direction means any new small HMO needs consent, and the council usually refuses further conversions where student occupation is already concentrated. Clarendon Park sits at the heart of Leicester's HMO Article 4 area, first introduced in 2013 and extended in 2022, so converting a family house to a small house in multiple occupation needs planning permission and is routinely refused near the universities.
Some two-storey rear extensions are permitted development. You will need a full application to Leicester City Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things Leicester City Council checks first — then submit a validation-complete pack.
Below is Leicester City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leicester grants the large majority of householder applications, but in Clarendon Park the defining tension is intense student-HMO demand meeting the Article 4 controls that restrict further conversions. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

Across Queens Road, Montague Road and Springfield Road, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On late-victorian and edwardian red-brick terraces, matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.
The Stoneygate conservation area boundary reaches into Clarendon Park, so frontage, boundary-wall and roof detail are held to conservation standards on those streets. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.
We draw two-storey extensions across Clarendon Park. A few of the areas where they come up most often:
Two storey extension drawings for Queens Road — the shopping spine framed by tightly packed Edwardian terraces — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
Two storey extension drawings for Montague Road — grid of red-brick terraces with front bays and small forecourts — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
Two storey extension drawings for Springfield Road — wider terraces edging into the Stoneygate conservation area — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
Two storey extension drawings for Howard Road — student-dominated terraced streets close to the University of Leicester — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
Two storey extension drawings for Avenue Road Extension — later terraces linking Clarendon Park to Knighton — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
Two storey extension drawings for Clarendon Park Road — the district's namesake terraced street of period frontages — dimensioned against the 3m and 7m limits and drawn to Leicester City Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Leicester City Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how Leicester City Council validates and decides two-storey applications.
Send us your Clarendon Park postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Leicester City Council decisions.
We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.
Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.
We submit the application, manage validation and case-officer queries, and revise the drawings free until Leicester City Council issues its decision.
Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Clarendon Park, the 7-metre rule is what most commonly forces a full application to Leicester City Council.
No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Clarendon Park gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Leicester City Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Leicester City Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference. This applies to your Clarendon Park address specifically.
Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Clarendon Park address specifically. Leicester City Council is the decision-maker.
Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from Leicester City Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Clarendon Park address specifically.
Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Clarendon Park address specifically. Leicester City Council is the decision-maker.
